Mix-Minus
The mix-minus signal may be programmed to be pre or post fader:
SW6 assigned MXM1
SW7 assigned MXM2
The default setting is “post”.
The dipswitch SW5 turns ON/OFF the mix-minus feed:
SW5 position 3 assigned MXM1
SW5 position 4 assigned MXM2
Timer Restart
When the module is turned ON, the console’s digital timer can be
programmed to automatically reset to zero and begin counting up.
SW2 position 4 activates timer restart when mic A is turned ON
SW3 position 4 activates timer restart when mic B is turned ON
Tallies
Turning the module ON can activate a remote tally indicator. There are
three tally control lines: on-air, tally 2 and tally 3. The first two positions
of dipswitch SW5 (to the left of the fader) program these functions:
SW5 position 1 activates tally 2
SW5 position 2 activates tally 3
The thirds position of dipswitch SW1 activates the on-air tally control
line (factory default setting).
Talkback
Typically, one of the console’s MM-5000 input modules will be used
for the control room (CR) console operator’s microphone. The fourth
position of dipswitch SW1 allows that microphone to also function as a
talkback mic. It places the signal (post-insert, pre-pan, pre-fader, pre-on/
off) onto the console’s talkback bus. When the console operator presses a
TB switch on the console’s SCD-500 Studio Control module, the talkback
bus (which is carrying his microphone signal) will interrupt the regular
monitor signal being fed to the studio and talent will hear his voice through
the studio monitor speakers.
In order for the studio to reply to the console operator, the MM-5000
module controlling the studio’s microphone signal must be routed to the
console’s cue bus, where it can interrupt the regular control room monitor
feed and be heard by the operator. This is accomplished by a user-supplied
TB switch in the studio. The switch provides a momentary closure
between the module’s lower DB-25 connector “TB to CR A” or “TB to CR
B” control pins and Digital Ground (see page 2-6 for wiring details). As
long as this closure is maintained (i.e., as long as talent holds down the
studio TB button) the module’s (post-insert, pre-pan, pre-fader, pre-on/
off) signal will be placed on the console’s Cue bus. Simultaneously, the
module’s regular output will be muted (i.e., Cough will be activated) so the
