2.0 DESCRIPTION OF CONTROLS
2.1 BYPASS switch
Pressing BYPASS cancels gating by removing the side chain voltage from the
voltage controlled amplifier (VCA). The Input-Output and level change circuitry
remain in the signal path.
The BYPASS led lights when the compressor is Bypassed.
2.2 LISTEN switch
This facility allows the side chain signal to be monitored at the channel output.
This is useful for tuning the side chain filters by ear.
2.3 HI-PASS control
This control sets the cut off frequency of the high pass filter in the side chain
signal path. Side chain signals at frequencies below the cut off frequency are
attenuated and so will not operate the gate.
Use this control to prevent low frequency signals, such as a miked up bass drum,
opening the gate.
2.4 LO-PASS control
This control sets the cut off frequency of the low pass filter in the side chain signal
path. Side chain signals at frequencies above the cut off frequency are
attenuated and so will not operate the gate.
Use this control to prevent high frequency signals, such as a miked up hi-hat
cymbal, opening the gate.
Please note:
The filters are always in the side chain signal path so if not required it is
necessary to set the controls to their extreme frequencies to prevent them
affecting the side chain signal.
