Group Outputs on Row G are after the I/O module Bus Trim control. These are
normalled down to Row H. Row H feeds the Multitrack Sends (i.e. the multitrack
inputs) and also the GROUP monitoring button. The GROUP button on a module
will always monitor a Multitrack Send even if the Groups have been cross patched.
ROWS L to S – Some jacks are cross normalled and these are detailed below together
with certain inputs and outputs, the wiring of which may not be immediately obvious.
Note that the following descriptions are based on a 48-channel patchbay. According to
the size of your console, there may be some variation in the layout of rows beyond
Row K. Rest assured that all the functions and normalling described below will be the
same for all consoles, regardless of the actual location of those functions.
PRE VCA INS (L1-4, M1-4) – Four insert points after the LCRS bus mix amps and
before the Main Output VCA Fader (and 4-channel Compressor). These insert points
can be used to insert other compressor/limiters or EQs into the main desk outputs.
MAIN OUTPUTS + DISTRIBUTION (L5-L9, M5-M9) – These are the main LCRS and
Mono Outputs from the console. L5-8 carry the main LCRS Outputs which are
normalled down to the main LCRS distribution jacks M5-8. These four jacks feed the 4-
Track and Stereo Recorder jacks L11-L40. 4-Track 1 and Stereo 1 are fed directly from
M5-8; all the other Recorder feeds are buffered. The three sets of 4-Track Recorder
inputs (L11-22) are derived from the LCRS outputs (M5-8). The stereo machine inputs
(L23-L40) are fed from the L and R Outputs, M5 & M7.
The four Distribution jacks (M5-8) can be useful for multi-machine tape copying.
Plugging the source signal into M5 and M7, for example, will feed the inputs of all
Stereo machines connected to jacks M23-40.
TAPE MACHINES (L, M, N, P 11-40) – Four jacks for each machine track. The top jack
(Row L) provides the console main output which is normalled to the machine Record
input (Row M). The machine Replay output comes up on Row N and is normalled
down to the External Monitor Selector inputs (Row P). The inputs on Row P are very
useful if you need to meter a signal. For example, patching into jack P23 and selecting
EXT 1 on the External Selector 1, with the main meters selected to EXT 1, will bring
the source up on the Left main meter.
STEREO BUS OUTPUTS and INSERT RETURNS (N1-8 and P1-8) – These provide a
post main level control Output/Insert for the four Stereo Subgroup busses, A, B, C
and D. If used as an insert point for external limiters, EQ etc., the effect will be applied
before the busses are folded back to the main LCRS mix busses (See Sections 2 and 5
for more on this). The Insert Return jacks (P1-8) feed External Monitor Selector 1 and
also the console’s connector panel for connection, if required, to an external layback
machine.
