Main Module
Input Section
The upper section of this input module selects one of four
stereo line inputs. The electronically balanced line input section
has left and right center detent input gain controls (with PCB-
mounted calibration trimpots for fine adjustment), left and right
phase reverse switches and a patch point INSERT switch (stereo
insert points are electronically balanced in and out).
AUX Section
This section taps eight summed (L+R) post-EQ auxiliary send
signals from the main input channel and routes them to the
console’s send ACN busses. There is a pre/post selector switch
and an ON switch for each pair of aux circuits. NOTE aux circuits
may also be programmed to operate as left/right stereo pairs via
PCB-mounted programming dipswitches (see page 2-19). Also,
while aux pre/post switches normally switch before or after both
the channel fader AND channel On switch, special PCB-mounted
slide switches (four per module) permit dual AUX pairs to follow
main channel ON/OFF even when switched to “pre” (page 2-19).
BAL Control – MODE Switch
The center-detent BAL rotary control operates in conjunction
with the module’s MODE switch. Here are the possible settings
and functions:
Stereo Mode (ST) – Default setting (MODE switch cap illumi-
nates); the rotary control functions as a regular L/R stereo
balance pot.
Mono Mode (MN) – Rotary control functions as a pan pot (a
L+R summed signal is panned L/R within the module’s
stereo field).
Right Mode (RT) – Rotary control pans the right channel
signal L/R within the module’s stereo field.
Left Mode (LT) – Rotary control pans the module’s left chan-
nel signal L/R within the module’s stereo field.
Bus Assign
Each input module may have its output assigned to any
combination of the console’s two stereo MASTERS and/or eight
mono SUBMASTERS.
Note the module is available in two versions: one assigns a
summed L+R channel signal to the eight mono SUBMASTERS
(“SI-88”; left panel); the other assigns the module’s stereo signal
to L/R pairs of SUBMASTERS (i.e., 1-2, 3-4, 5-6, 7-8; “SI-84”;
shown on right panel).
