The routeing switch (16) to the left and right mix busses is, in effect, the channel 
mute. 
 
Panoramic potentiometer - panpot - (33) routes the module's signal proportionately 
between the left and right mix busses. 
 
MON (18) routes the true (L/R) output from the module to the monitor module where 
it can be treated as an AFL (after-fader listen) signal or as an SIP (solo-in-
place) signal. MON is independent of L-R routeing (16) and is derived from the output 
of the panpot and 'S' switch (15) if selected. 
 
Pre-fader listen (19) with its LED indicator (20) is a third way of aurally monitoring the 
module. 
 
The overload LED (21) illuminates 3dB before clipping at the input to the fader. 
 
The Penny & Giles fader (34) is calibrated 10dB down from its fully open position, 
allowing the operator to work with 10dB of gain in reserve. Faders on adjacent 
modules can be coupled for stereo operation by the use of standard ganging clips.
