Page 6: Introduction
Additionally, we have succeeded in refining the audio properties as well as the circuit topology. For the first time, the AUTOCOM PRO MDX1400 uses SMD technology (Surface Mounted Device). These sub-miniature components known from aerospace technology allow for an extreme packing density, plus improve the unit’s reliability. -

2. CONTROLS Fig. 2.1: AUTOCOM PRO front panel The BEHRINGER AUTOCOM PRO has two identical channels. Each channel is equipped with 8 backlit push-buttons, 7 rotary controls and 26 LED’s. The COUPLE switch is for stereo operation: By engaging the COUPLE switch the AUTOCOM PRO is converted to stereo mode, where the controls of the left channel take over the control of both audio channels. -

Page 11: Applications
3. APPLICATIONS In this section, several typical applications of the BEHRINGER AUTOCOM PRO are discussed. The following basic settings can resolve most dynamic problems. They are the ideal starting point. Please take the time to study the application examples carefully, in order to be able to make full use of the AUTOCOM PROs capabilities in the future. -
Page 12: Expander/Gate Section
Noise gates however, can be seen as “high ratio” expanders. If the signal falls below the threshold, it is radically attenuated. The BEHRINGER AUTOCOM PRO is equipped with a newly developed IRC (Interactive Ratio Control) Expander, the ratio of which is automatically adjusted dependent on the program material. The response characteristics of conventional expanders tend to cut into the signal abruptly and the result of this is unacceptable most of the time. -

Patch the BEHRINGER AUTOCOM PRO into a snare drum channel for example and adjust it so that triggering only occurs on snare hits. Each mic should be set to its maximum operating level, monitored (see SC MON switch) and the THRESHOLD level set so that each snare hit sounds acoustically clean and seperate, as though it was played on its own. -
Page 14: Reducing Feedback In Stage Mics
It will prove useful to use the BEHRINGER AUTOCOM PRO as the last component in the chain of effects units and use the noise reduction function of the Expander/Gate section. We recommend that you use a slow release time in order to maintain the natural reverb. -

Page 16: The Autocom Pro As A Sound Effects Unit
The AUTOCOM PRO MDX1400 offers a solution to this problem that is by much more elegant. The SC Filter switch allows you to activate a highpass filter in the control signal path of the compressor. This filter makes sure that midrange and treble range frequencies are taken into account to a greater extent, and that a low-frequency signal triggers less compression than a midrange/treble signal of comparable level. -

It is recommended that you use the Behringer AUTOCOM PRO in order to protect the speaker. “Brick Wall” peak limiters are not normally necessary for PA systems, as amplifiers and loudspeakers are tolerant of short signal peaks. -
Page 19: Protection Of A System With An Active Crossover
4.2.2 Protection Of A System With An Active Crossover For systems using active crossovers, there are two ways to use the BEHRINGER AUTOCOM PRO. The unit may be inserted between the console output and the crossover input. In this application, the BEHRINGER AUTOCOM PRO will process the entire audio frequency spectrum. -
Page 20: External Sidechain Applications
When de-essing, simply insert an equalizer not into the audio path but into the sidechain path of the BEHRINGER AUTOCOM PRO. The equalizer is inserted between the SC SEND output and the SC RETURN input of the BEHRINGER AUTOCOM PRO. -

5.2.4 Emphasizing Musical Instruments During Recording On the other hand, you can use the BEHRINGER AUTOCOM PRO to bring out an instrument solo or a lead vocal in a cluttered mix. Using the SC MON switch, match the frequencies of the equalizer to the frequencies of the instruments to be emphasized and for this it is best to use a notch filter with a high slope. -

Compressor and Dynamic Enhancer sections are switched off. The bass guitar track is connected to the audio chain of the BEHRINGER AUTOCOM PRO, while the bass drum is connected to the SC RETURN input. By activating the SC EXT switch, the bass guitar is now triggered by the bass drum. -
Page 23: Compressors/Limiters
The need therefore arises for a fast acting automatic gain control system which will constantly monitor the signals and which will always adjust the gain to maximize the signal-to-noise ratio without incurring signal distortion. This device is called a compressor or limiter. This system is a part of the BEHRINGER AUTOCOM PRO. Compressors/Limiters By measuring the dynamic range of musical instruments in live recording situations, you will find that extreme amplitudes occur which often lead to overload in subsequent signal processing equipment. -

7.1 Inputs And Outputs 7.1.1 Balanced Inputs And Outputs As standard, the BEHRINGER AUTOCOM PRO is installed with electronically servo-balanced inputs and outputs. The new circuit design features automatic hum and noise reduction for balanced signals and thus allows for trouble-free operation, even at high operating levels. Externally induced mains hum etc. will be effectively suppressed. -
Page 25: Audio Connections
The BEHRINGER transformer OT-1 is designed to the highest exacting standards and is available as an accessory. The audio inputs and outputs on the BEHRINGER AUTOCOM PRO are fully balanced. If possible, connect the unit to other devices in a balanced configuration to allow for maximum interference immunity. -
