A basic prerequisite for creative work in a sound engineering institution is it's technical equipment. One may place no limits on artistic ambitions and ideas. The recording studios, control rooms, and workstations at the Erich-Thienhaus-Institut are based on today's highly technological industry standards. A glance into the microphone cabinet reveals that each student is provided with great tools to record both serious and entertainment quality music.

Another special feature is the networking of all of the campus's recording-equipped rooms, making acoustic and visual communication virtually limitless. This limitless ideology also applies to time availability; the equipment and premises are available to students around the clock.

Control Room 1


Control room 1 was fundamentally and extravagantly modernized at the end of the winter semester in 2013.  The centerpiece is the digital SSL C200 console which follows in the footsteps of the legendary analog SSL console, just with current digital possibilities.  The console has 32 channel strips, 32 + 8 faders, 64 channel DSP and can accommodate up to 128 I/O's.  The playback consists of a 5.1 ATC system, which can be coupled with a Trinnov room correction system.  Alternatively, there are several near-field monitors available including the standard reference NS-10's.

Recording and editing is done on our ProTools|HDX2 system with 128 I/O, UAD2 Duo-Card and various software tools for editing, correcting, and replication of recorded material.
The finest analogue outboard and gear and multi-effects devices (Lexicon 480, TC System 6000, Bricasti M7) are available to the students for coloration.  All ProTools systems are connected to a central hard-drive (24TB Raid 6).  Here each student has their own volume for all of their work.  Control room 1 is connected to all cutting rooms of the ETI, as well as the main concert hall.  Some ribbon microphones (Royer/Coles), a Neumann M 149, and a Brauner Valvet X Pure Cardioid complement our extensive microphone collection as well.
Finally, this control room is suited for lessons and seminars with ProTools sessions mirrored to a 46" LCD, a laptop table, etc., providing excellent conditions for intensive studies and work in the field of popular music.


Control Room 2


Control room 2, equipped with the digital Aurus (StageTec) console is used mainly for classical music recordings. The best listening conditions are met with the B&W Nautilus 802 (5.0 surround), as well as a pair of Geithain RL903's. 48 microphone channels are provided for recording from the neighboring main concert hall.  The audio editors Pyramix (Merging) and Sequoia (Magix) are available.  Both programs allow for easy synchronization between the DAC and the Aurus console.  A Lexicon 960L provides high quality hall reverbs and effects.



Brahms Hall Control Room


The Brahms Hall is located in the main building of the university, the Palais, and, aside from some larger lectures, is used as a smaller concert hall for chamber music, evening lectures, class auditions, exams, etc.  It holds about 200 people.

As part of the renovation work on the Palais in 2006-2007, this control room was planned and implemented from scratch.  The room is centered around a Yamaha DM2000 mixer, and for the friends of the good old analog sound, a Studer 269 in alternatively available.  Five Geithain RL903's serve as either a stereo or 5.1 playback system.

Again, the sound recording students can choose from either the Sequoia (Magix) or the Pyramix (Merging) DAW's.  There is a Bricasti M7 reverb processor for creating the correct sense of space, as well as a Tascam CD-recorder for "Live to 2 Track" recordings.


Big Seminar Room


The big seminar room has excellent acoustics as a classroom and listening room alike.  It was designed and built by the Geithain company under the leadership of its chief developer Jürgen Kiesler.  The room can be used for listening in 5.2 surround and stereo at "reference quality" and conforms to ITU standards.  There are five Geithain 901K monitors and two alternative ATC SMC 50's available.  The room was equipped with an acoustically transparent, motor powered projection screen along with an acoustically insulated projector.


A rolling C|24 console allows you to work with both Pyramix and ProTools|HD Native.  Both Pyramix and ProTools are equipped with the Lexicon PCM native plug-in and ProTools|HD Native boasts countless plug-in bundles of all popular manufacturers.  A UAD-2 Quad-Card and a SPL-16/2-Analog Summing-Unit as well makes this setup ideal for mixing "in-the-box."  A modern monitoring matrix (Grace Design m906) routes out the possibilities.

Since the room is fundamentally a multifunctional design, it offers other uses such as live broadcasts of sound and video, mixing sessions, seminars, and recording sessions.

Small Seminar Room


The small seminar room is used mainly for educational purposes.  A whiteboard, a screen with a projector, as well as various audio players are available to meet this purpose.  A piano is available for studying work, stylistic analysis, and music interpretation, as well as use for practice outside of lectures.

Cutting Studio 1 and 2


Our recording studios were designed for a nearly neutral sound and are mainly used for pop music recordings.  New mobile absorbing panels can be used to shape the rooms and reduce crosstalk and bleed.  A Steinway B grand piano is in studio 2.  A large sound insulating glass pane is used to simplify communication between band and ensemble members playing in two separate recording rooms.  A Fender Rhodes, Leslie cabinet, and Marshall amp complement the musical possibilities.
Hearback-systems are in place in moth studios, in which artists may create their own headphone mixes.  Further, both studios feature modern patchbays (XLR, CAT5, MIDI, Re-Amping Lines, BNC, LWL).

Main Concert Hall


The "Konzerthaus Detmold" is the largest concert hall of the Hochschule für Musik and holds about 600 people.  Built in 1968 as "Neue Aula," the building was reopened after a two year renovation phase in May 2009 as the "Konzerthaus Detmold."
The sound recording students enjoy significantly improved acoustics with a reverberation time of 1.5 seconds, and with an electro-acoustic reverberation system by the SIAP company, reverb time may be increased to up to 5 seconds.  The hall has had a four-manual John Kleis (Bonn) organ with more than 50 speaking stops since the original opening.  As part of the renovation, the organ was made to be fully MIDI compatible which makes for a valuable contribution to the practical recording classes.





Equipment forms the basis for a full scientific and technological sound engineer training program.  The upstairs lab is a combination of an anechoic measuring room and an electronics workshop, but also provides enough space for small seminars.  Here various electrical, acoustic, and electro-acoustic investigations and experiments are performed.

The university maintains a Matlab license with signal processing and a DSP toolbox for simulations and calculations.

A large selection of high-quality measuring instruments is available in the lab such as a dScope system (Prism Sound), a mobile Monkey Forest system (Four Audio), as well as various B&K Precision measuring instruments, digital voltmeters and oscilloscopes (Fluke, HP, Tektronix, Voltcraft).

For room and building acoustics studies, a globe source with 12 individually controllable speakers (Outline) with an optional subwoofer (Kling & Freitag SW 118E-SP), a Minirator Pro (NTI), a 2231 B&K sound level meter, and an XL2 sound analyzer (NTI) with an enhanced acoustics package is all available.

There is even a HUGO and HD2 crossover (Four Audio) as well as a "Noise-bomb" (Neumann) available for the field of electro-acoustics.  DSP Development-Boards (Analog Devices) and Visual DSP++ Software can be used for exercises in digital audio technology.

In 2009, the laboratory was extended with its anechoic chamber for the acoustic analyzes of speakers, microphones, and musical instruments.

Reverberation Chamber

Bild 005_Hallraum.JPG


The oblique, tiled room in the basement of the ETI has an extremely long reverberation time which offers a variety of uses.  Starting from the founding of the institute the room was used as a reverberant resounding space, and the connection to using musical signals with the spatial characteristics of the room was natural.  As an acoustics laboratory, it also allows for two measurement applications: The determination of the degree of absorption of insulation materials, as well as the determination of the power of sound sources.

Wave Field Synthesis


The Hochschule für Musik Detmold has had two wave field synthesis systems for different applications since 2009.  The main concert hall is equipped with a WFS installation by Sonic Emotion.  Over 300 speakers in the walls and ceiling of the concert house allow playback of up to 16 virtual sound sources at arbitrary locations inside and "outside" the hall.

The integration of a method for extending the reverberation by SIAP allows for the progressive extension of the reverberation time of 1.5 sec to 5 seconds.  This allows, for example, the authentic performance of church music and organ works.  Another example of the application of the WFS technique in church music is the realization of a virtual remote work.

A second WFS system from IOSONO is located in the WFS space below the main concert hall and has 80 coaxial speakers and 4 subwoofers on which up to 32 virtual sound sources can be positioned.  This system allows full control of acoustics and sound source arrangements under studio conditions.  It is mainly used for teaching, research, and multitrack productions.


Swallow's Nest


This small control room clings like a swallow's nest under the roof at the rear of the main concert hall.  It was remodeled and furnished as part of the modernization and reconstruction of the "Neue Aula" to "Konzerthaus Detmold."  This control room is primarily used to record small concerts.  To this purpose, therein lies a Yamaha O2R in combination with an RME Octamic providing 16 microphone channels.  The recording students may again choose between either Pyramix or Sequoia.  If the room presents insufficient acoustic space, a student may use the supplied Lexicon PCM91.
Furthermore, the DAW in the swallow's nest will be used with Logic (Apple) for WFS applications in the concert hall.  A KVM-extender allows for free positioning for DAW control in the hall.


Further Control Rooms


Students have fully equipped editing suites with Sequoia, Pyramix and ProTools|HD Native available at the ETI.

In the Detmold Summer Theater, one finds another ETI control room which allows the student to record numerous special concerts here in this theater.  The Summer Theater control room has a StageTec Cantus desk and the audio editor Pyramix.

The redesigned video room houses an editing suite with Pyramix or Sequoia, and a separate post production suite with Final Cut Pro.  Two HD cameras - Sonx NEX-F100 - enable video recording.

Portable Equipment


In addition to several control rooms, the ETI has an extensive portable equipment collection that recording students may use to make field recordings of anything from small ensembles to large orchestras.  Gear provided includes at least one mobile Pyramix, Sequoia, and ProTools|HD workstation with various pre-amplifiers, an analog Studer ReVox mixer, a modern communication system (Producer.COM), and various monitor speakers.
The ETI is also well quipped for impulse response radiation.  Here should be mentioned that among others, six PA Kling & Freitag speakers, various FOH FX racks and both a Yamaha PM5D and O3D are also available for remote projects.  Two complete HD camera rigs are available for video projects as well.
