Konfigurator2 V166 Beta test:

Since this week, two dozens of soundman and colleagues have been busy with the new K2 Beta release.
This is the largest K2 field test ever made. From Windows XP SP3 to Windows 10.
The Apple Beta version will follow in the coming days.

The first feedbacks are very positive, but it remains exciting to see if any optimizations are necessary
and how these might look.






Hoellstern Calendar 2017
 

In the next few days, our beautiful calendars will be sent to all Hoellstern users.

If you have not received one yet, but would like to have one or more:
Please let us know! The calendar will be sent free of charge as long as stocks last.




Konfigurator2 library - october 2016:

A new K2 library was stored on the K2 server to add E5 and X12.
Please make sure that the amplifier firmware must correspond to load0007 (7,7,3,1,1 September 2013).



K2 firmware:

A new firmware load is underway. Among other things, the mute functions and internal self-test functions have been optimised.
The soft mute functions now offer a considerably shorter attack time, enabling a faster setup check with larger applications.
Once the new K2 firmware has been released, all registered K2 users will be notified by e-mail.



Konfigurator2 V16X:

A new Konfigurator2 is work in progress. Various features and functions to facilitate your daily routine have been added and optimised.
Among them is also the K2 installer which incorporates the latest programming directives from the operating system makers (Windows and Apple) for the supported OS versions.
And: WIN XP is still supported. Once K2 V16X has been released, all registered K2 users will be notified by e-mail.



K1 to K2 amplifier update service to be discontinued:

After 48 months of successful K1 to K2 updates, this service shall be discontinued with effect from November 30th, 2016.



In-house event technology trade fair on May 3, 2016

Dear PA renters, sound engineers and business partners,

on May 3rd we will be represented at the Wonneberger in-house event technology trade fair in Chemnitz, where several PA systems will be driven by Hoellstern amplifiers. On the site we will answer your detailed questions regarding the Konfigurator2 software, K2 loudspeaker libraries and the amplifiers.

The official opening is on May 3., 2016 at 2 p.m. in 09117 Chemnitz, An den Gütern 7.

You are cordially invited to this event.
We are looking forward to meeting you.



Cologne-Huerth April 19, 2016 – Successful and efficient sound reinforcement the easy way

We would like to express our heartfelt gratitude for the lively participation in Cologne-Huerth and the numerous intense talks.

The guests came from England, the Netherlands, Sweden and Germany. In the hall the Hoellstern amps could demonstrate on the speaker systems how a successful sound reinforcement on a high level can be achieved easily and efficiently by using innovative solutions.
The horn-loaded groundstack system was run on one DELTA20.4-DSP, likewise the groundstacked line array was driven by only one DELTA20.4-DSP, and the two bananas including flying subs and infras were fired by only four 20.4-DSP amps on four 16 A Schuko outlets.

The sound was great and near the end of the event at higher volume levels we still had 6db of headroom and a mighty output above 25 Hz. Totally controlled without breaking away or getting mushy.

The acoustic excitation of the 1800 sqm [19,375 sqft.] hall below 40 Hz got indeed quite massive or even frightening. Prolonged subbass test sweeps from electronic music were equally pumped out mercilessly and with utmost control by the 20.4-DSP amplifiers.
Much to the delight of road-proven sound engineers, who, in view of the hall size and the achieved sound levels, typically would rather have fallen back on 10 or 12 4-channel power amplifiers from other makers on 32 A phases each. Four 16 A Schukos and 4 x 2 RU caused a good deal of positive irritation.
The four DELTA20.4-DSP amps were kind of self-explaining.





Technology Day Cologne-Huerth on April 19, 2016

The official invitation with all the details can be found here.
We are looking forward to your visit!



Prolight+Sound | Cologne Technology Day | Paul Carrack's UK Tour

We would be pleased to welcome you in hall 4.1 at the SOMMER CABLE booth E40. On Wednesday and Thursday we from Hoellstern Amplifiers will be in attendance.

Please put a big red mark in your calendar for April 19: a Technology Day will take place in Cologne where interesting PA solutions with Hoellstern amplifiers will be demonstrated. Details and invitations will follow.

Early this year the Paul Carrack tour was underway in the UK. Around 35 shows took place in a wide set of renowned houses. PA and monitoring were driven by Hoellstern amplifiers.Video footage on this including statements and more can be seen at youtu.be/OTYqAmOssbE or at proaudio-technology.de
The Birmingham Symphony Hall enjoys a first-class reputation worldwide.

Dante Audio Network - (cost) effective

From late April 2016 the batch production of the Dante module unD4O will be launched at Atterotech USA.
The module feeds the corresponding signals to the four analogue inputs of the Hoellstern 4-channels power amplifiers.
Those signals can then be slaved further from amp to amp again.
That way linking Hoellstern amplifiers to Dante becomes a cakewalk.

This is practice-oriented, because not every amp needs to be implemented elaborately into Dante, which greatly reduces the time requirement on real jobs.
Moreover, the audio system setup does not depend on the Dante audio network, but is effectuated autonomously like before with the DSP amplifiers serving as "black boxes".
This clear separation guarantees a markedly enhanced safety during the jobs.

Please contact us for more specific details.

The sound was crystal clear

The positive electrical and acoustical qualities of Hoellstern amplifiers are widely known among those sound engineers who work with them regularly. Sure, one can explain acoustical properties, but you have to listen to and work with them to have a strong say.

Currently there’s a major live tour in the UK which is powered by Hoellstern amplifiers exclusively. Extensive coverage on this will follow later, of course. A topical quotation from the internet may serve as a preliminary teaser:
"...Thank you for the fantastic gig last night at the G Live in Guildford. ... It was one of the best gigs we have been to, the sound was crystal clear, you could even hear the hi-hat patterns from Jack and Dean on drums..."



Amsterdam ISE 2016



Meet us at the ISE 2016 in Amsterdam from February 09 – 12. Many relevant manufacturers from Germany, UK, USA and other countries will be present at this exciting trade show. Flight connections to Amsterdam are very good throughout, flying outward in the morning and getting back home in the evening is just a breeze.

The Hoellstern distributor for Benelux will be on duty with Rob Roosen and his colleagues not only at the ISE booth, but also in a demo room 15 minutes away from the exhibition grounds where a number of Hoellstern amplifiers will drive various PA systems.
Talk to us. We will gladly arrange a meeting in advance and look forward to your visit.

Return on Investment

Recently the ProMedia News Weekly e-mail brought the following report about the dry-hire situation (quote):
"The dry hire market currently doesn't have an easy time. The fast product cycle is badgering the Return on Investment, the big players – favoured by high purchase discounts – offer rental fees that are hard to beat, and the lack of market transparency does one last thing."

The described situation is grist to our mill. Since the year dot, Hoellstern amplifiers have had a power circuitry which, because of its positive qualities, does not require any changes.

5 or 8 kW of audiophile Hoellstern power were audiophile power without any discussions back in 2004, they still are in 2015 and also will be in the next decade. There's no getting around it.

Moreover, the fact that the Hoellstern Konfigurator2 and the Hoellstern DSP library help to achieve a future-proof and unique flexibility, is equally undisputed.

To pick up the quote in the ProMedia News Weekly again in a positive sense: right from the start Hoellstern amplifiers were not just load stable, but also offered lasting value. This is partly because we do not reinvent the wheel every year, but because we develop and produce in an uncompromising manner.

This is our contribution to the Return on Investment with Hoellstern customers, to the environmental protection and the healthy way for the almost family-like pro audio branch.



Germany’s #1 Techno Parade


The Beatparade – 25th July 2015 – is growing more and more into a large festival.
For years the Hoellstern amplifiers have been around here.

This year one thing was particularly striking:
All the trucks (one truck with Kling & Freitag and five trucks featuring ProAudioTechnology) were equipped with a total number of more than 20 Hoellstern DSP amplifiers.

The experience of the organising companies gathered over the years has shown that with high temperatures and maximum strain Hoellstern amplifiers are the right choice to bring big power to the ravers in a no-compromise, audiophile way. So here again it’s not just about sound levels.

The impressions from the Beatparade:

Summer Never Ends Festival 2015


Once more the SNEF was technically supervised by the Megatron Veranstaltungstechnik AG from Switzerland.
Like in the previous years, technical director Dirk Stirnimann was responsible for the Kling & Freitag system design.
This year 14 Delta 14.4s, 14 Delta 20.4s and 4 Delta 12.2s were in use. That's badass Hoellstern power under badass conditions.
Goa festivals are known to strain the material to the limits.

Hoellstern amplifiers at the Prolight+Sound 2015

In the Live Sound Arena at the PLS2015 three DELTA20.4-DSP amplifiers were used to drive the new VT20 line-array system by ProAudio Technology with a total of 12 VT20 elements and 16 18" drivers in the VS18 and VS28 subwoofers in a cardioid mode. Due to the cardioid bass array the PA was powered with a third DELTA20.4-DSP amplifier. In omnidirectional mode only two DELTA20.4-DSPs would have been required.

On the VT20 system the Hoellstern amplifiers could show what they’re made of.

With a relaxed headroom between 9 and 15 dB, the level limits were very well observed, as the trade fair organisers said. Renowned sound engineers who are regularly on tour working on different systems, were greatly impressed by the overall performance. According to their statement the entire system had stood out very pleasantly against all others.
Because of the high resolution of the custom-equipped VT20 tops, the DELTA20.4-DSPs could very well demonstrate how cleanly a PA can play in terms of reverberation rooms, spatial imaging, resolution and directness – even over larger distances.
Bringing up the song "Die Tänzerin" by Ulla Meinecke as the first track is a very risky endeavour for testing PAs, but here the listeners got goose bumps.
Supported by the subwoofers the result was a very punchy, assertive, extremely controlled and natural sound image down to below 30Hz.

Hall 8.0 saw the presentation of the new Hoellstern Remote Unit with its large graphic touch display.
For users who want to go without a computer with K2 to set up the basics via DSP on site, this proved to be a fine novelty. The corresponding data sheet can be found here under Products.
We would like to say a big thank you
to all visitors and wish you a successful year 2015.



Prolight+Sound 2015 – Frankfurt, Germany



From April 15 until April 18, 2015 we invite you to visit our exhibition booth in Frankfurt.
Here you can talk shop with us about Konfigurator2™, loudspeaker libraries and amplifiers.

In the Live Sound Arena 4-channel amplifiers will drive an extremely powerful and
audiophile front PA (vertical line array).
Two DELTA20.4-DSP amplifiers impressively demonstrate in 2.7-ohm and 2-ohm mode
what they can do and what makes the Hoellstern amplifiers and their technology so unique.

We’re excited to get your feedback. We will also gladly arrange a fixed appointment with you
to discuss goal-oriented solutions and options.

Booth: Hall 8, booth C18. Only 3 minutes walk away from the booth:
Live Sound Arena, daily at 11:15 a.m., 01:15, 03:15 and 05:15 p.m.



Konfigurator2™ Loudspeaker Library - Hoellstern amplifiers
are audiophile all-purpose talents:

The comprehensive Konfigurator2™ loudspeaker library keeps growing, based on the
user requirements. An up-to-date table of the available setups, sorted by manufacturers,
can be found here: Konfigurator2™Library

Nexo - Presets, Loads and Hardware

Hoellstern amplifiers join everything on one common ground.
No matter if NX AMP 4x1, NX AMP 4x4, NX241, NX242, with or without
CAI card, analogue TDMK2, new or old loads – with the Konfigurator2™
the Hoellstern loudspeaker library brings everything down to a common
denominator: Hoellstern amplifiers.
Irrespective of the Hoellstern amp model.

How does this work?
In Konfigurator2™ select the DSP technology and move the loudspeakers for each channel by drag&drop to the memory.

Upload, activate, demute.
And it performs. Time and again. Also in the future.


P.S.
Currently the K2 library is updated on the basis of the NX AMP setups.

NX AMP setups are not comparable to and incompatible with the setups of
the external Nexo controllers.
At Hoellstern we therefore distinguish between Nexo and Nexo-NX.
Of course, the same also applies to other loudspeaker manufacturers, and
Nexo is just an example.

With Hoellstern Amplifiers you get the free choice and the longterm support.

DELTA 6.2-DSP

The DELTA 6.2-DSP is a 2-channel Hoellstern amplifier with built-in DSP and 2 ohm load stability, which can be operated and configured from the K2 version V159.

Besides the technical properties and the ample, universal loudspeaker library the amplifier impresses with an extremely attractive price-performance ratio.

Considering the costs per speaker, these cannot be achieved in this high quality even with self-powered solutions.
The roll-out of the DELTA6.2-DSP amplifiers has begun.



CAUTION!
Important note on pre-owned Hoellstern amplifiers offered for sale

In the light of recent events it is highly recommended to communicate us the serial numbers, pictures and owner contact data.
When in doubt about the alleged owners, it is very advisable to pay only after a validation of the data and if you have the amplifiers physically in front of you.

Otherwise it might happen that you will never receive the already paid 2nd-hand amplifiers, and the alleged seller has dropped off the face of the earth.



DELTA 20.4(-DSP)

The DELTA 20.4(-DSP) is the most powerful 4-channel Hoellstern amplifier.
The rollout has now begun.



DSP loudspeaker library keeps growing

The Konfigurator2™ loudspeaker library is permanently enlarged.
Please contact us in time if specific loudspeaker setups are required.
The appropriate K2 loudspeaker block will then be made available.

For instance, TW AUDiO presets in the A03 version, like T24N-A3 and B30-A3, are also available as of now.
As a feature the internal DSP delay has been left open in these loudspeaker blocks, i.e. the normally fixed latency of the A03 version can be reduced from 5 ms to e.g. 2 ms.

Prolight+Sound 2014



Thank you very much to all visitors for their keen interest.

During the trade show days all questions regarding our amplifiers, new products, the K2 software and the comprehensive loudspeaker library could be answered in a competent way.
The daily presentations in the outdoor area (ProAudio Technology stage in front of hall 8.0) were an excellent example of what could be done easily with two DELTA14.4-DSPs.
The acoustic performance of the 12 subwoofers, 4 horn-loaded tops and 2 infills (see review Production Partner 10/2013) offered an incredibly spatial acoustic rendition with a very deep stage imaging.

Quite often one could hear people say: "Now that’s high-class sound reinforcement."

Prolight+Sound 2014 – Frankfurt, Germany

Meet us at the Prolight+Sound in Frankfurt from March 12th – 15th, 2014 in hall 8.0, booth C18.

Here you can catch up on Hoellstern amplifiers, vendor-independent loudspeaker libraries,
K2 software and accessories.

Besides product novelties our new sales representative Torsten Grosse will also be present.
With 25 years of work experience Torsten Grosse is a competent reference person for professional sound engineering.

In the outdoor zone (Live Sound Arena), not far from our exhibition stand, Hoellstern DSP amplifiers can be checked out each day at 2-hourly intervals (11:15 a.m. and 01:15, 03:15, 05:15 p.m.).

We are looking forward to your visit!



New Distributor for Italy

We dearly welcome Audio Network as the new Hoellstern distributor for Italy!
The company based near Milano has been active for many years as distributor in the pro audio sector for renowned manufacturers like CADAC Mixing Consoles.

Mr. Damiano, CEO of Audio Network:
"Markets move increasingly forwards to the low-cost manufacturing, every day the overall quality perceived drops a lot ... our the passion and mission of our company is to bring back the hi-fi quality in the professional audio industry.
Since the early tests with Hoellstern amplifiers, Hoellstern we realized there was something really special, Hoellstern amplifiers are the missing link in the chain of audio quality! The great buildt-in quality and superb sound, are really impressive!
We believe deeply that Hoellstern can really change the way we listen to music, for these reasons we decided to distribute Hoellstern amplifiers in Italy."

Hoellstern Amplifiers are System

The principally infinite number of base setups in Konfigurator2 allows different combinations of IIR filters and FIR with totally variable distributions of DSP resources of the base setups. We call this DSP SoftCore technology.
This DSP technology constitutes the basis for the ample, constantly growing Konfigurator2 loudspeaker library.
That’s future-proof lego for all sound reinforcement and PA systems.

The HT16 Tourset review in the Production Partner pro magazine, issue 10 / 2013, attests the performance capability in the measurements. Despite a passive 2 way crossover in the HT16 top a perfect acoustic phasing from 250 Hz up to 20 kHz is achieved. This produces an outstanding acoustical imaging and an amazing in-the-face directness.

Alcons Audio reveals its potential on the DELTA13.4-DSP

A DELTA13.4-DSP amplifier is the perfect drive to replace 2 or 4 ALC4 power amplifiers.
For the users the performance increase in the sub range just like in the high/mid range of the line arrays
is a true revelation.

The effect of the missing sense return is neglectable. Owing to the load stable dynamics, the 3-D sound image and the clean, controlled reproduction even with high levels and over the entire frequency bandwidth, the systems receive an enormous quality push, also with the Hoellstern® amplifiers driven in a 4 x 2 ohms operating mode.
In practice the overall improvements bring about key benefits.

Any questions regarding the upgrade? Please contact us in writing.

All company names, product names, product designations and logos mentioned in this text are
registered trademarks owned by their respective holders of rights.



DELTA12.2 and DELTA12.2-DSP



As of now the new Hoellstern® DELTA12.2 and DELTA12.2-DSP 2-channel amplifiers are ready for sale.
Their output power is 2 x 2,2 kW into 8 ohms, 2 x 4,4 kW into 4 ohms and up to 2 x 8 kW into 2 ohms
with a peak current of 2 x 125 A.

The amplifiers weigh 10 kg in a 2 RU enclosure of 30 cm depth. Because of their high efficiency,
a 16 A mains connection is sufficient.
In practice the relatively small no-load current and the high efficiency will result in lower mains
requirements and reduced energy needs.

Like with all Hoellstern® amplifiers the sound properties are on a high level.
Due to the modest fan noises they can also be used at industrial events.



Astonishing:

"We set up the Danley today with DELTA14.4-DSP so we can hear what it really sounds like;
The amplifier is astonishing, certainly the best PA amplifier I have ever heard.
Maybe even as good as my favourite high end hi-fi amp!
Thank you!"

"I know these monitors could sound better!"

A nice anecdote from a hip recording studio in the Zurich area:
Prince Rogers Nelson dropped by this August after a concert for some recordings and commented on the sound of the studio monitors "I know these monitors could sound better!"
Not without reason the studio crew had already got scent of Hoellstern® amplifiers some time ago through the Swiss-based Tucton company.
Without further ado Tucton had to deliver an amplifier from their demo pool to the studio.
The bottom line was: "Hey man, that's it!"
You need to know that the multi-talented artist runs his own studios in the USA.



Large GOA festival

A Hoellstern® AMP city with DELTA13.4 and DELTA14.4 was used this summer to amplify a very large GOA festival.
Just like in 2010, both the organisers and visitors were very pleased with the performance of the entire sound system.

Slim 8 KW amplifier solution for 4 to 16 ohms: DELTA8.4-DSP



From 4-way monitoring to full-fledged front PA applications, ASID GmbH presents a new Hoellstern® power amplifier: the DELTA 8.4-DSP. With a built-in 4-channel DSP, remote control option, free DSP configuration, powerful and stable outputs plus all IN and OUT protections of the DELTA amplifier series.

In "ON" mode each of the 4 channels of the DELTA 8.4-DSP delivers 1,300 watts at 8 ohms and 1,700 watts at 6 ohms, in "OFF" mode the output power is 4 x 850 watts at 8 ohms or 4 x 1,700 watts at 4 ohms resp.

The proven Hoellstern® DSP loudspeaker management with 4 discrete audio inputs has also been integrated. The setups of the global manufacturer-independent Hoellstern® loudspeaker library are available free of charge. They raise the safety margin, facilitate your daily routine and are future-proof. Like all other Hoellstern® amplifiers, the DELTA 8.4-DSP may be comfortably operated via an RS-485 network under Windows and Mac using the free Konfigurator2™ software.

Who doesn’t need the flexibility typical of Hoellstern® amplifiers (load stable down to 1 ohm with certain models) won’t have to pay for it, either. Owing to the current limitation to 35 ampères on the output side, the design of the DELTA 8.4-DSP – with the same high quality level – could be realised in a more cost-effective model. Looking at the resulting overall performance and its four separate inputs, under economic aspects the DELTA 8.4-DSP is a very interesting 4-channel amplifier for all loudspeaker systems. It is easy to operate, highly flexible and the constantly updated loudspeaker library will reduce your costs even further.

The new Hoellstern® DELTA 8.4-DSP rounds off the series of 4-channel amplifier models by Hoellstern® in a reasonable way.

Successful start in Korea
with BLS Best Leading Solutions Co., Ltd

Since mid 2010 BLS has been the exclusive Hoellstern distributor for Korea.


Udo Höllstern, the managing director of Hoellstern Amplifiers: "We are really glad to have found such a professional partner for Korea. During the past five years a lot of Korean sales companies were knocking at our door, but with BLS we have found the optimal distributor.
Only a few months later we could already see that, despite the large geographical distance, a very close and efficient communication is possible – for us a basic prerequisite with regard to optimal results. A short time after the first ProAudio projects were already stipulated, and in November Hoellstern Amplifiers will be represented by BLS at the Korean KOSOUND + STAGETECH 2010 (Kintex exhibition ground)."



Authorisation for the Korean market received: K-Mark certificate

In the 4th quarter of 2010 the products from Hoellstern Amplifiers have successfully passed all international
EMC and safety tests.
An important milestone of our international activities and another evidence for the quality of our products.



Konfigurator2: The release of the first version ...

will take place within a few weeks in the 4th quarter of 2010.
During the past few months the Hoellstern team has tested extensively and, among other occupations, made the distribution partners familiar with the powerful functions. Some practical things have been added and improved since the demonstration at the Prolight & Sound 2010 - thank you very much for your constructive feedback.
Thus e.g. the integration of any desired loudspeaker systems in one (!) software interface and amplifier platform will open up new, promising horizons in the daily routine of sound reinforcement.

Essential factors are brought down to a common denominator.



Mini rock festival 2010 in Horb am Neckar

Audiophile Cost Effectiveness: Hoellstern® DELTA13.4




The Hoellstern® DELTA13.4 amplifier will particularly please those users who don’t need the tremendous 5,000 watts output power at 2 ohms delivered by the DELTA14.4 amplifier.
In one operation mode each of the 4 channels of the DELTA13.4 amplifier provides 1,300 watts at 8 ohms or 3,800 watts at 2.7 ohms with the load stability that Hoellstern® amplifiers are known for. In the second operation mode it delivers an output power of 850 watts at 8 ohms or 3,400 watts at 2 ohms resp.
The DELTA13.4 amplifier is available with or without DSP loudspeaker management. The DSP option features four separate, simultaneously operative audio inputs, something which is compulsory for practice-oriented and cost-efficient monitor applications.
As to its weight, it ranks barely below the DELTA14.4 amplifier. Given its overall performance the Hoellstern® DELTA13.4(-DSP) amplifier should be extremely interesting for both permanent installations and technical service providers, and this not only for economic reasons.
Like all other Hoellstern® devices, the amplifier can be comfortably operated via an RS-485 network using the Konfigurator2™ software. The Hoellstern® loudspeaker library is equally available and can be easily used by drag & drop. Hence your cost-benefit calculation will work out fully.



Hoellstern Amplifier Day Wilhelma Stuttgart


In Stuttgart the new Hoellstern® Konfigurator2™ software was demonstrated and explained in detail to the audience which was principally involved in the permanent installation sector.
Despite their technical complexity, the freely configurable individual channels and the DSP architecture and also the Hoellstern® loudspeaker library can be operated with Konfigurator2™ in an easy, practice-oriented way.
We give thanks to all participants for your visit.

Our heartfelt thanks go also to the Wilhelma Theatre for their kind support.

Hoellstern Distributor for BeNeLux:
Tau Audio Solutions


One year ago, Hoellstern Amplifiers and Tau Audio Solutions from the Netherlands started to investigate the possibilities of a distribution in The Netherlands and BeNeLux.
Since April 1st, 2010 Tau Audio Solutions has taken over the exclusive distribution of Hoellstern Amplifiers for the entire BeNeLux area.
We are glad to have found a serious partner such as Tau for distributing our audio amplifiers in the ProAudio market. Tau Audio Solutions is in the position to serve the ProAudio market with our Hoellstern products.

Ron Vossen (CEO of Tau Audio Solutions):
"Tau was established in 1997, this month we have been in the business for 13 years. Starting out in the market niche of audio induction loop systems, we soon included 100V public address systems as well, followed by voice alarm systems. The nature of these products and business fields implicates that quite some time and effort were involved in advising our customers. We just can't deliver some amplifier without knowing exactly what the customer intends to do with it. Apparently we have chosen the right strategy because suppliers and customers appreciate this approach.

Brands we represent in the NL are:
Ampetronic since 1997, Australian Monitor, Baldwin Boxall and Penton since 2000 and Soundtube since 2004.

With a staff of 8 people we keep trying to improve in what we do.
As a reference for our quality of work:
Right now we are completing a project regarding an induction loop system for the Dutch parliament, the most important conference and congress room of our country."

Hoellstern Amplifier Days at the Prolight+Sound 2010


The Hoellstern Amplifier Days at the Prolight + Sound were used extensively by the visitors to establish and deepen personal contacts. The Hoellstern amplifier users could take a close look at and operate the comfortable Konfigurator2™ software during operation.
Besides the chance to create your own user setups, the expanding Hoellstern loudspeaker library may be accessed in a freely programming manner. Currently the brand-independent Hoellstern loudspeaker library is worldwide unique in this style and quality. The freely and reasonably selectable DSP architecture offers an enormous, future-proof flexibility and allows to utilise DSP setups of any given loudspeaker manufacturer in high quality. Due to the extremely short latency of 0.2 ms, all external controllers and power amplifiers can also be emulated with respect to their latencies.
It's reassuring to know that during the past three years the team of Hoellstern Amplifiers has measured and analysed more than 5,000 setups regardless of their brandnames.Thus we were able to build up a pretty comprehensive wealth of experience comprising all kinds of analogue and digital setups of many loudspeaker makers. This knowledge is successfully made available to the users free of charge in the form of the ample and steadily growing Hoellstern setup library, the Konfigurator1™ and the new Konfigurator2™ software: Hoellstern amplifiers as the universal platform.
The roll-out of the Konfigurator2™ (Windows and MAC) will begin in June 2010. For additional information please contact the Hoellstern team.

To all our visitors we would like to give our warm thanks for their great interest and the confidence shown to us.

Summer Never Ends Festival 2009

From July 30th until August 2nd 2009 the Summer Never Ends Festival took place in Switzerland.
Live acts and DJs from all over the world were performing nonstop action on two floors, playing electronic music from Elektro to Dark Psy.
http://www.summerneverends.ch/summer_never_ends/
In 2009 the sound technical planning and coordination lay in the hands of the Tucton company from Switzerland.
The open air mainfloor covered an area of 100 x 70 metres.
It was the stated aim to fill both floors with as little frequency response and SPL deviations as possible.
According to the organiser and all people involved the requirements were met to the utmost satisfaction or even surpassed.
All loudspeakers used were exclusively driven by Hoellstern power amplifiers.

The sound system for the open air mainfloor consisted of:
18 x Hoellstern DELTA14.4
30 x K&F Sequenza 10 linearray unit
24 x K&F Sequenza 10B subbass
14 x K&F Access B10 ultrasub
04 x K&F CA 1515 monitor
09 x K&F CD44 controller

The sound system for the dancefloor tent consisted of:
08 x Hoellstern DELTA7.2.2
12 x K&F Access B5
04 x K&F Access T5
04 x K&F CA 1515 monitor
07 x controller K&F CD 44

The entire sound system was running nonstop at high volume levels from Thursday 6 p.m. until Sunday 8 p.m.

The Hoellstern Setup Library is constantly updated and extended

As of now four setups (with and without LowCut) for the small Meyersound MM4 loudspeakers are also available. The equalisation and limiting functions of the Meyersound MM4-ECU controller have been very precisely emulated. No less than 64 of these midgets can be driven by one Hoellstern DELTA12.4(-DSP) 4-channel amplifier in SYM mode without exhausting its power limits. Thanks to this modern amplifier solution various analogue controllers and the necessary sense-return cabling can be dispensed with completely.

And by using the digital delay function you can also create typical delay lines (as they are commonly found with music and voice reproduction for theatres and industry) without the need for additional devices.

The benefits and utility are quite obvious: on balance, the expense, costs and sources of error can be greatly reduced with a Hoellstern DSP amplifier solution.

Furthermore, this application shows that even such tiny industry loudspeakers can be driven in a cost-efficient manner with a Hoellstern high-power amplifier.

Hoellstern Amplifiers with internal DSP

In connection with the Hoellstern setup libraries Hoellstern amplifiers make an innovative and highly profitable platform. By combining powerful electronics with setup libraries for a wide array of loudspeaker brands, Hoellstern users get an "open" system electronics able to drive any available loudspeaker systems. Classic external controllers and power amplifiers as well as power amps with built-in DSP may be replaced entirely by Hoellstern amplifiers.



3rd Hoellstern Amplifier Day near Berlin

The 3rd Hoellstern Amplifier Day was a highly informative experience for the invited guests. Especially impressive were the load stability and the high tonal level of the DELTA amplifiers, but also the precision of the Hoellstern setup emulations. Besides thorough technical information on the Hoellstern amplifiers and details about the product and company philosophy the visitors were shown how to operate the Konfigurator1 software, the extensive Hoellstern setup library comprising a wide range of manufacturers which will be available by the end of 2009.

Our established A/B crosschecks with "on the fly" switching option were demonstrated in Berlin in a practical way on 3 exemplary setups:

  • 12 T10 elements (line source configuration) with 8 Q-subs and 4 D12 power amps by d&b against one Hoellstern DELTA14.4-DSP amplifier.
    It was impressive for the guests attending how one DELTA14.4-DSP with 2 RU and a weight of about 12 kg can replace four D12 power amplifiers with a total of 12 RU and a weight of approx. 52 kg with no losses in terms of audio quality.
    Technical Info (PDF)

  • 10 EAW KF730 elements with 6 Concert Audio ESX subs, EAW UX8800 controller and 2 LAB FP10000Q 4-channel amplifiers against 2 DELTA14.4-DSP.
    Whereas LAB Endstufen power amps and 2 x 18" subs at 2 x 8 ohms (8 ohms per channel) revealed minor weaknesses regarding bass control, with Hoellstern amplifiers all visitors were noticing a subjective 4-6 dB level increase in the 2.7 ohms mode (3 x 18" subs with 2.7 ohms per channel) with a markedly improved bass control and came to the conclusion that at least 3 LAB Endstufen would be needed to achieve an approximate performance like 2 DELTA14.4s.
    Technical Info (PDF)

  • 4-channel NEXO PS15, 2 NEXO digital controllers NX241 and 2 Camco V6 power amplifiers A/B'd against a DELTA14.4-DSP with the analogue (TDMK2) and digital (NX241/2) PS15 setup emulation in 4-channel (4 IN – 4 OUT) fullrange operation mode.
    Here again it became obvious: using only one DELTA14.4-DSP amplifier, notable savings in weight, rackspace and costs are achievable without compromising in the least on audio quality.
    Technical Info (PDF)

The Hoellstern team is giving a warm thankyou to all visitors.

We will continue to hold the Hoellstern Amplifier Days in 2010 once more. The dates will be announced in due time.
We are looking forward to meeting with you again

2. Hoellstern Amplifier Day in Stuttgart / Wilhelma Theater

"The amplifier is the engine and gearbox of a PA system"

On June 15th 2009 the 2nd Hoellstern Amplifier Day took place in Stuttgart. Already before the official opening at 4 pm many listeners and interested guests had gathered in the Studio room. Experts representing the business fields of event technology, technical service, permanent installation and theatre were on the scene.
In a direct A/B comparison with the original system electronics, the visitors were listening very closely to the systems from d&b and Nexo powered by Hoellstern amplifiers. Not only was the obvious precision of the Hoellstern setup emulations impressive, but also the A/B-demoed electrical stability of Hoellstern amplifiers at loads below 4 ohms striking. Until 9 pm A/B checks were conducted with almost no break and – which is equally important – comparisons made of acquisition costs, weight and truckspace. The practical listening and viewing brought the message home to the audience how easy and convenient it is to use Hoellstern amplifiers with built-in loudspeaker management and 300 setup memories. And one more point became very clear: the amplifier is the engine and gearbox of any sound system.

Their acoustic performance, 4 ultra-stable channels, a weight of 12 kg and a switchable 4-IN DSP controller with precise setup libraries for many loudspeaker manufacturers make Hoellstern amplifiers a truly audiophile, economic and versatile tool.

The Hoellstern team gives warm thanks to all visitors and is looking forward to the next listening reunion in Stuttgart 2010.
A special "thank you" goes out to the Wilhelma Theater Stuttgart for the uniquely beautiful ambience.



Advance notice 3rd Hoellstern Amplifier Day:

The 3rd Hoellstern Amplifier Day will be held in Berlin in September 2009. Once again, four products from various loudspeaker manufacturers will be used for the A/B comparison. Furthermore we will also demonstrate a 4-channel power amplifier A/B check with an external controller. Probably at least one large line array system will be at hand. Details will be published in the News section. You will also receive an invitation in writing.

Africa! Africa!

The international magic circus event (www.africancircus.de) from the continent of wonder - exclusively amplified by eight 4-channel Hoellstern DELTA power amplifiers.




DELTA14.4(-DSP) on the road

Since June 2007 Hoellstern 4-channel DELTA14.4(-DSP) amplifiers have driven successfully various Nexo Line Arrays Geo S and D plus Cardioid Subs CD12 and CD18.
8 RU of 4-channel Hoellstern amplifiers replace a full 16 RU of stereo amplifiers, i.e. reduced weight + cost + truckspace and increased overall performance. Built-in DSP available as an option.

(Nexo is a registered trademark of the respective rights holder.)




PS15 and PS10 powered by DELTA14.4-DSP

The European tourn 2007 of rock legend Lou Reed (USA) was successfully amplified using a 16-channel PS10 and PS15 monitoring powered by DELTA14.4-DSP.
With a latency of 0.2 ms, the internal 4 IN / 4 OUT 96 kHz DSP controller provides a directness with monitors that is only known from analogue controllers.




DELTA14.4 - Cool economists may show emotions

4 x 1350 watts at 8 ohms. 2 x 5000 watts at 2 ohms (channels 1/2) plus 2 x 2600 watts at 4 ohms (channels 3/4).
All housed in a 2 RU enclosure of 29 cm depth weighing only 12 kg. Like with all DELTA models, an integrated 4 in / 4 out 24 bit / 96 kHz loudspeaker management is optionally available.
This amplifier excels by extreme versatility and efficiency.
The DELTA 14.4 reduces dramatically the number of amplifiers otherwise needed and is perfect for systems between 2 and 16 ohms. In practical use its high and stable output power at 16 ohms down to 2 ohms will allow you to replace 2 or even 4 conventional power amplifiers.
Its audiophile sound properties and uncompromising manufacturing quality are of course identical with those of our other Hoellstern amplifiers.

Our sincerest thanks to all visitors we had the pleasure to welcome personally at our fair booth. Many guests had our products explained very attentively and were visibly impressed by our live demonstrations of the PA-SYS-ONE (driven by Hoellstern DSP power amplifiers) in the outdoor area.

For us - hopefully just like for you - this year's Prolight & Sound was a complete success with sympathetic and informative talks, new contacts and splendid motivation.





 

Prolight+Sound 2006

We are looking forward to your visit! You will find us in hall 8.0, booth J54. From Wednesday until Saturday between 10:30 and 11:30 a.m. or between 3:30 and 4:30 p.m, you will also have the opportunity to listen to and look at our power amplifiers at the Live Sound Forum in the outdoor area of the exhibition site.
These will drive the TWAUDiO speaker systems and the SLS line arrays by audioconcepts.
Following critical tests and extensive crosschecks, both manufacturers use our amplifiers in their demo AMP racks.







  New Hoellstern logo

All ASID power amplifiers are going to have the "Hoellstern" logo milled into their 8mm front panels. The DELTA power amplifiers carry the last name of the designer in charge: Udo Höllstern.
The technical specifications will remain unaltered.




New products

From December 31st, 2005, the models DELTA10.4.4 and DELTA7.2.2 will go into serial production.
The DELTA10.4.4 is designed for single-ended applications, where up to 4 channels with a max. output power of 2600 watts per channel are required.
The "small" DELTA7.2.2 is designed for 2-channel purposes and like all DELTA amplifiers delivers a souvereign performance at critical loads, owing to its derated 10 kW power supply. Together with the DELTA10.4.2 power amplifier you will get perfectly matched tools for demanding PA applications.




Preliminary information: new models - September 2005 -

From our designer workshop: By the end of 2005 we will expand the DELTA power amplifier series.
The 4-channel power amplifier DELTA 10.4.2 (total output power 11.000 watts, available since January 2004) will be joined by the model DELTA7.2.2. The new 2-channel power amplifier DELTA 7.2.2 will be produced in two versions with 1 and 2 HU rackmount cases. Sound properties, design and quality are identical with the DELTA 10.4.2.



Preliminary information: prolight+sound 2006 - September 2005 -

The upcoming prolight+sound 2006 shall be a platform for presenting our power amplifiers to you and keeping in touch with business friends. We are already looking forward to all our customers and potential buyers who are enthusiastic about our DELTA series.
