7 COMPOSER PRO MDX2200 1. INTRODUCTION In purchasing the new COMPOSER PRO MDX 2200, you have acquired an extremely efficient and universal dynamics processor, which combines the most commonly used dynamic functions within a compact stereo unit: every channel has its own independent compressor/limiter, an expander/gate and a peak limiter.
8 COMPOSER PRO MDX2200 1.1 Before you begin The BEHRINGER COMPOSER PRO MDX2200 was carefully packed in the factory, in order to ensure safe transport. Nevertheless, should the box show signs of damage please check the equipment itself immediately for any signs of external damage.
9 COMPOSER PRO MDX2200 1.2.4 Transformer balanced outputs (optional) In contrast to electronic balancing, the use of transformer-balanced outputs offers the advantage of galvanic separation between units. Electrical potential differences and ground loops in audio installations do not there- fore impair the performance of the units.
10 COMPOSER PRO MDX2200 3 The RATIO control is used to adjust the expansion ratio when the signal drops below the threshold value. This control determines whether the unit works as an expander (low ratio level) or as a gate (1:8). The expansion ratio can be set from 1:1 to 1:8.
11 COMPOSER PRO MDX2200 13 Using the SC MON switch will enable you to connect the side chain control signal to the audio output, whilst at the same time muting the audio input. This function provides you with the ability to monitor the side chain signal that is returned via inserted equalizers or other external processors.

Please take the time to complete and return the warranty card within 14 days of the date of purchase, otherwise you will lose the right to the extended warranty.
13 COMPOSER PRO MDX2200 also cause uncontrolled currents and voltages. The resulting sound of the various frequencies is heard as noise. Even the best possible tape biasing can “only” provide signal-to-noise ratios of about 70 dB, which is not acceptable today since the demands of listeners have increased.

15 COMPOSER PRO MDX2200 inaudible as soon as considerably louder sound signals in the same frequency band are added. Nevertheless, the further the level that the desired signal decreases, the more the noise floor becomes a disturbing factor.
16 COMPOSER PRO MDX2200 average level without affecting signal peaks above the threshold, this is referred to as the program limiter. For this purpose the attack time will be set above 20 ms. If the attack time is further reduced in order to also control signal peaks, this is defined as the peak limiter.
17 COMPOSER PRO MDX2200 4.2.1 Controlling leakage in the studio Expander/gates are most commonly used to suppress undesirable leakage of sound from one track to another during recording or playback. They are usually used when recording drum kits, where the mics are very close to each other.
18 COMPOSER PRO MDX2200 4.2.3 Reducing leakage in stage mics The COMPOSER PRO has many uses in live-work, on stage and in multi-miking situations: a well set up expander/gate can effectively suppress background noise, compressor type pumping noise and microphone leakage etc.

20 COMPOSER PRO MDX2200 technique is required, the attack and release times can also be manually adjusted. The experienced user will be in a position to specify parameters while in bypass mode and thus realize the effect before the unit is actually switched into operation.

22 COMPOSER PRO MDX2200 5.1.1 The COMPOSER PRO in digital recording and sampling In an analogue recording, too low recording levels lead to an increased noise level, whereas too high levels will cause a compressed and “squashed” sound. In extreme cases, it will cause distortion due to tape saturation.
23 COMPOSER PRO MDX2200 5.2.1 Protection of a system with a passive crossover If your sound system incorporates a passive crossover network (included in the loudspeaker case), insert the BEHRINGER COMPOSER PRO between your mixing console output and the power amplifier input.
24 COMPOSER PRO MDX2200 6 . EXTERNAL SIDE CHAIN APPLICATIONS 6.1 The side chain function The BEHRINGER COMPOSER PRO offers an exceptionally usable external facility by using the side chain function. By activating the SC EXT switch, the COMPOSER PRO’s control path is disconnected from the audio input and therefore interrupted.
