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:

1

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. The control signal for the control

characteristic consists of either the sum of the left and right audio signal or the sum of the external audio

signals, which are being fed into both SC RETURN connectors. By pressing the COUPLE switch, you

override all the controls and switches of channel 2 with the exception of the IN/OUT, SC EXT, SC MON,

SC FILTER and I/O METER switches as well as the OUTPUT and PROCESS controls. As a result, the

controls of channel 1 take over the functions of channel 2.

+

Should you wish to use the SC EXT function in stereo mode, then be sure that both SC RETURN

jacks are connected to the external control signal, and that the SC EXT switches on both

channels are engaged.

Use the THRESHOLD control to determine the threshold point below which expansion occurs. The

range of this control is from OFF to +10 dB.

When a signal above the threshold value is applied, the “-” LED lights up, while the “+” LED lights up

when expansion occurs.

To optimally adapt the expander/gate to the program material, the RELEASE switch allows for selecting

a SLOW or FAST release time. When you engage this switch, the expander responds with a slow

release. As a general rule, percussive material with little or no ambience is processed using the FAST

release mode, whereas signals with long decay or with heavy ambience require the SLOW release

mode.
