Controls and Functions
A
AC INLET
- IEC standard AC Power cable
Connector.
B
CHANNEL 2 XLR INPUT
- XLR Balanced line
input.
C
CHANNEL 2 1/4” TRS INPUT -
1/4” TRS
Balanced line input.
D
OPERATING LEVEL SWITCH
- Switches the oper-
ating level from -10dB to +4dB.
E
CHANNEL 2 KEY INPUT
- Input connection
allowing external control of the S•com plus’
Compressor detection circuit.
F
CHANNEL 1 KEY OUTPUT
- S• com plus’ detec-
tor circuit is sent here. Use the Key Output to

external effect like an equalizer.
1
GATE OPEN & CLOSED LED
- Indicates when the
gate is open and closed
2
GATE SWITCH
- Selects either Gate or Expander
mode.
3
GAIN REDUCTION METER
- Displays the amount of
Gain Reduction when Compressor circuit is activated.
4
INPUT/OUTPUT METER
- Displays the Input or
Output signal level based on the settings of the I/O
meter switch.
5
ENHANCE LEVEL
- Used to set the level of the S•
com’s Enhanced Spectrum Recovery circuit restoring
the high end loss resulting from extreme Gain
Reduction.
6
STEREO LINK SWITCH
- When engaged channel 2’s
functions are controlled by the settings on channel 1.
