MULTICOM PRO-XL MDX4600/COMPOSER PRO-XL MDX2600/AUTOCOM PRO-XL MDX1600 User Manual

With this new dynamics processor from the PRO-XL series you have acquired 

an extremely powerful and universal compressor which unites in one compact 

device all of those dynamics control functions that are most frequently used in 

practice: each channel has an independent compressor/limiter, expander/gate 

and peak limiter. Thus, virtually all dynamics processing problems can be 

remedied with little effort.

Future-oriented BEHRINGER technology
The new PRO-XL dynamics processors from BEHRINGER feature several innovative 

circuit designs, making them top-class dynamics processing equipment. 

Compared to their predecessors, they now have improvements such as the 

de-esser, which allows you to effectively suppress disturbing hiss noise 

(COMPOSER PRO-XL), additional LED displays to set the de-esser levels, plus a 

switchable enhancer. 
The AUTOCOM PRO-XL not only includes an enhancer, but also a switchable 

de-esser and a peak limiter, which has already proved its versatility in the 

COMPOSER PRO.
The BEHRINGER MULTICOM PRO-XL has been upgraded with an expander/

noise gate plus enhancer. Additionally, we have managed to improve its audio 

properties even further—in combination with a revised circuit design.
To give you the best operational reliability possible, we manufacture our 

products in accordance with the highest quality standards known in the industry. 

Additionally the dynamic processors are manufactured under ISO9000 certified 

manage ment  system.

VAD (Voice-Adaptive) De-esser
The COMPOSER PRO-XL and AUTOCOM PRO-XL incorporate a newly designed 

de-esser circuit specifically adapted to process the critical range of treble 

frequencies. Hiss noise on vocal tracks often contains high levels, giving the 

signals a rather edgy, unpleasant sound. The de-esser responds to those 

frequency ranges in which hiss noise usually occurs and limits the overall signal 

level as soon as the audio signal is affected by excessive energy density in this 

range. Unlike equalizers, however, it does not impair the frequency response of 

the signal. In this way, intelligibility in low-level passages is perfectly preserved, 

and you can even boost the treble range with a good equalizer. The sound 

becomes transparent and fresh, while the de-esser prevents hiss noise from 

becoming too dominant and disturbing the overall sound image.

IDE (Interactive Dynamic) Enhancer
Probably the best known negative side effect of a compressor is the “dull” and 

“compressed” sound that is likely to result from the processing of complex 

program material. Low-frequency instruments usually produce the highest signal 

energy and hence make the compressor reduce the overall level. Any instrument 

in the higher frequency ranges concurrently played also has its level reduced, 

which leads to a “compressed” overall sound.
The dynamic enhancer provides the solution to this problem, enabling you to 

make up specifically for the compression-induced loss of treble energy. Since the 

enhancer can detect the amount of compression applied, it does not change the 

sound image as long as the signals remain uncompressed. No treble energy is 

lost, even when complex mix-down material is processed.

ATS (Authentic Tube Simulation) circuitry
Even today, the warm, expressive and transparent tonal character of electronic 

tubes is a real “classic”. We proudly present the COMPOSER PRO-XL and its 

high-tech circuit design enabling the authentic reproduction of this legendary 

sound, and at the same time avoiding all of the technical drawbacks that 

go along with tube technology. Owing to state-of-the-art semi-conductor 

technology, there is no sound deterioration caused by tube ageing, there are 

no heat problems and no maintenance required at all. All that remains is the 

advantage of tube technology: its distinctive sound!

IKA (Interactive Knee Adaptation) Compressor
Our proven IKA (Interactive Knee Adaptation) circuit successfully combines 

the “hard knee” compressor concept with the “soft knee” characteristic. 

This program-dependent control characteristic makes it possible to both provide 

an “inaudible” and musical program compression and allows for creative and 

efficient dynamics processing.

IRC (Interactive Ratio Control) Expander 
A fundamental problem when using a compressor is the fact that the basic 

noise floor depends on the amount of compression applied, i.e. it is amplified 

maximally in low-level passages and breaks in the music (compressor noise). 

To eliminate this problem, compressors are usually equipped with additional 

expander or gate circuitry, simply fading out the noise during breaks.
The dynamics processors from the PRO-XL Series feature our IRC (Interactive Ratio 

Control) expander, whose ratio setting changes automatically with the 

program material. The result is an expander that can be set quickly and easily, 

and does not cut off low-level wanted signals (e.g. the first or last syllable of 

a word in a vocal track). With the new IRC circuit, the expander/gate section 

of the BEHRINGER COMPOSER PRO-XL MDX2600,  AUTOCOM PRO-XL MDX1600 

and MULTICOM PRO-XL MDX4600 can be used as an independent device to 

eliminate any kind of interference, thus giving you almost unlimited flexibility 

of application.

IGC (Interactive Gain Control) Peak Limiter 
Another outstanding feature of BEHRINGER dynamics processors is the IGC 

(Interactive Gain Control) limiter, an intelligent combination of a clipper and 

program limiter. The clipper comes in as soon as an adjustable threshold is 

exceeded and abruptly limits the signal gain. However, if the limiter threshold 

is exceeded for longer than a few milliseconds, the ICG circuit is activated 

automatically and reduces the gain of the overall output signal, so that 

audible distor-tion is eliminated (program limiter). When the signal drops 

below threshold again, its level is restored to its original value after about one 

second. This IGC feature is an extremely usefull tool for both live applications 

(e.g. speaker protection) and digital processing, in which excess levels lead to 

unpleasant distortion.
