9.2. Stereo
Each stereo channel features a mono microphone preamp as well as two
stereo line inputs. These three sources can be used independently or
mixed together into channel, so providing a unique flexibility. For example,
you could configure a conventional mono microphone channel with the two
‘short return’ stereos routed direct to LR for effects. Alternatively you could
patch the mic stage as an independent preamp for an ambience
microphone feeding a recording, or for a system calibrate microphone,
while ST line inputs mix two external stereo effects processor return or
sound effect players via a single channel. This can be useful in saving
chennel, letting you mix many inputs in a small space. Of coursek, one
stereo could feed the chennl, the other route direct to LR. Two stero
channels could be linked so that the mic premps cross patch to provide
one stereo mic and one stereo line channel, with two ‘short returns’ also
available.
9.2.1. Mic input
Similar to the mono channel microphone preamp without the line (pad) and
polarity switches. Gain and 48V phantom power switching are included. A
rear panel mic out breakpoint socket is provided so that the mic stage can
be used independently. Plugging a jack into the mic out socket breaks its
signal path to the stereo channel.
9.2.2. Dual stereo line inputs
Each stereo channel has two stereo inputs which can be used separately,
mixed together or split so that one feeds the channel, the other routes
direct to LR, ST1 and 2 feed channel 15 (23), ST3 and 4 feed channel 16
(24). The L input signal is normally through the R input socket so that a
mono source may be plugged in to feed both left and right sides of the
stereo channel. Each input has its own level control to adjust from fully off
to +16dB gain. Centre position is unity (0dB) gain.
9.2.3. Routing mode switch
Recessed to prevent accidental operation. In normal up position the ST
signal mixes into the associated stereo channel. When pressed the signal
is routed direct to the LR mix instead of the channel.
