Stereo channel sends to the stereo matrices are sent
directly with the L/R balance determined by the source
channel.
Mono channel sends to the stereo matrices are
internally mixed to mono.

Mono master signals sent to the stereo matrices can
be adjusted for level (inner control) and L/R balance
(outer control).
Mono channel sends to the mono matrices are sent
with the L/R balance determined by the source
channel.
MONO
The level and balance of signals sent from the mono masters (group/
aux, mono) a stereo matrix can be adjusted via the inner and outer
controls, respectively. Stereo signals from stereo masters (stereo aux,
stereo) sent to a mono matrix are internally mixed to mono at the
matrix input and then routed to the appropriate mono matrix bus.
The stereo and mono master matrix input blocks also feature [SUB
IN] controls that allow signals from the MATRIX SUB IN inputs to
be sent to the matrix buses.
The console's talkback and oscillator signals can be fed to any matrix
bus by engaging the [TB/OSC] switch located to the right of each
[SUB IN] control (the talkback/oscillator signal is simultaneously
assigned to the L and R channels of stereo matrix buses). The
∑·PEAK indicators light when the matrix bus signal reaches 3-dB
below clipping. When a ∑·PEAK indicator lights it is advisable to
reduce the send level from the corresponding masters until the
indicator goes out.
