The BEHRINGER MULTICOM PRO has four identical channels. Each channel is equipped with 4 backlit push-
buttons, 4 rotary controls and 17 LEDs. The COUPLE switches are for stereo operation of two channels.

1
The
THRESHOLD
control sets the threshold point for the compressor section. It has a range of -40 to
+20 dB. If the channel is switched to INTERACTIVE mode (Interactive Knee Adaptation), a Soft Knee
characteristic is applied to the signal exceeding the threshold point by a maximum of 10 dB. Above 10
dB, the signal would experience Hard Knee compression.
2
The
RATIO
control determines the ratio between the input and output level for all signals exceeding the
threshold point. If the INTERACTIVE mode is used, this control determines the ratio between input and
output levels for signals exceeding the threshold point by more than 10 dB. The control range can be
adjusted from 1:1 to oo:1.
3
The
OUTPUT
control allows for the increase or decrease of the output signal by a maximum of 20 dB.
Thus, a level loss due to the compression or limiting process can be compensated for.
+
Please note when using the THRESHOLD control of the Peak Limiter section, that the OUTPUT
control of the Compressor section precedes the Peak Limiter section. If the OUTPUT control is
set too high, this can result in continuous peak limiting (see item 9 THRESHOLD control).
4
The
IN/OUT
switch activates the corresponding channel. This switch acts as a so-called hard-bypass
switch, which means that when the switch is OUT, the input jack is directly linked to the output jack.
Normally, this switch is used to perform a direct A/B comparison between the unprocessed and the
compressed or limited signals.
5
Press the
INTERACTIVE
switch to change from Hard Knee to IKA characteristics. IKA provides a very
subtle and musical compression of the program material and should therefore be used whenever
compression should be more or less inaudible.
6
The
SC FILTER
switch activates a highpass filter in the sidechain path and thus limits the influence of
low frequencies on the MULTICOM PROs control processes.
