When the POST switch is depressed, both the FB1 and FB2 paths are fed
post-fade; when the POST switch is released the signals are pre-fade.
Pan Control
32
The MON PAN control positions the Monitor signal within the stereo image
carried by the MONL and MONR buses. These buses connect with the Mix Left &
Right board where they are summed with signals carried by the MIXL and MIXR
buses, and also summed with Talkback signals (see the Stereo Master chapter for
more details).
33
The CHAN PAN control positions the Channel post-fade signal within a stereo
image. This stereo image may be connected to the MIXL and MIXR buses, and also
to the Group buses (1-8) by the use of the Routing switches (see Routing section
below).
Routing
34
Normally the post-fade, post-pan Channel signal is sent to the routing matrix.
This matrix is controlled by the switches marked, 1-2, 3-4, 5-6 and 7-8. When, for
example, the switch marked, 1-2 is depressed, the post-fade, post-pan Channel
signal is fed onto the Group 1 bus and the Group 2 bus. The Group 1 bus carries the
Left image from the Channel Pan control, whilst the Group 2 bus carries the Right
image from the Channel Pan control. Similarly for the remaining 3 matrix switches,
the odd numbered Groups carry the Left image and the even numbered Groups carry
the Right image.
The Group buses may be used to route the signal from one input channel to the tape
send of a different channel.
35
The stereo image may also be connected to the MIXL and MIXR buses, this is
done by depressing the MIX switch.
36
When the BOUNCE switch is depressed, the routing matrix is disconnected
from the Channel path and is, instead, connected to the Monitor path. This allows
the Group buses to be used for track bouncing.
Channel Path
37
The non-motorised Channel Fader feeds the CHAN PAN control and also
normally feeds the Tape Send. It may also be switched to feed Aux3 & Aux4, and
FB1
38
A multi-point peak detector illuminates the CHAN PEAK LED when less than
6dB of headroom remains at two critical places in the signal path: the Input preamp
and the pre-fade connection to the Channel Fader.
39
The Channel SOLO switch is a soft switch, i.e. this switch provides an input
to the Automation. The Automation , in turn, passes the Channel signal onto the
PFL bus and also switches the input of the Control-room/Headphones (CRM/PH)
circuit from its selected input to the PFL bus.
The Automation also indicates, by switching on the associated SOLO LED, that the
Solo is active on the Channel.
The Automation gives the Solo switch a toggle action: note that the switch itself
does not physically latch.
