Mono and stereo input modules are available for the S-Type. Both modules provide
balanced insert sends and returns; four band parametric EQ - selectable pre or post
insert and high-pass filter; balanced direct output - selectable pre/post fader, or post
MIC pre-amplifier,
Each module incorporates a VCA channel fader, VCA Master assignment switches
and a full range level meter (with dual input meters on the stereo input module).
Full details of the module functions can be found in chapters 4 Mono input module
8411 and 5 Stereo input module 8412 . Also, see Appendices .

Each of the output modules provide one Sub-Group output, an 8-way level controlled
send to Matrix, Matrix Master, and an Auxiliary Master output.
Up to 8 modules may be specified per console (maximum configuration being two
8413 and six 8415 modules) and each module can be placed anywhere in the multi-
frame console structure (they do not need to be placed adjacent to each other, or
even in the same frame). Visual monitoring of output levels is provided on full range
LED-meters, PFL facilities on the outputs are provided, as are balanced insert points
on the Sub-Group and Matrix outputs.
Full details of the module function can be found in chapter 6 Group, Matrix and Auxil-
iary Master modules, 8413 stereo and 8415 mono.

The Stereo Master module is fitted with a 100mm Penny & Giles fader, balanced
insert send and returns and balanced outputs (these are found on the rear of the
frame). The Stereo Master module also provides metering for both the main stereo
mix and listen busses, while the stereo mix bus can also be routed to the Matrix
sends in true stereo or summed mono via 4 dual concentric potentiometers.
Provision is made to inject an unbalanced stereo input source into the main stereo
bus.
The S-Type console offers the operator PFL monitoring functionality. If the source
signal is mono it will appear in mono and if the signal is in stereo it will appear in ste-
reo.
PFL appears at the Listen output, which provides stereo meters, level control via a
potentiometer and mute control. The Listen output busses appear on balanced
XLR's on the rear of the module. PFL is also routed to the Headphones level control
and mute, the output of which is provided via a jack socket on the front of the frame
and is capable of driving 8 ohm loads.
The module also incorporates an oscillator with selectable frequencies at 100Hz,
1kHz and 10kHz. This is then routed via a level control to either the channels or the
groups.
