6.5 Assigning Talkback to Aux Sends
When
TB/Slate
or
Comm
is pressed on the Digital Master Module, the Talkback
Microphone is summed into all Aux sends. If desired, the Talkback Mic can be removed
from Aux Sends by removing resistors on the motherboard that modules 17–24 plug into
(Assy No. 181506 or PB-8BSA).
The following resistors sum the Talkback Mic into each Aux send:
Aux 1 - R71
Aux 5 - R67
Aux 2 - R72
Aux 6 - R68
Aux 3 - R73
Aux 7 - R69
Aux 4 - R74
Aux 8 - R70
If a resistor is installed, the Talkback Mic will sum to the associated Aux Bus when
TB/Slate
or
Comm
is pressed.
Turn off the console and remove modules 17–24. The diagram below shows the location
of the Aux/TB resistors on the motherboard. All Aux/TB resistors are 10 k
Ω
,1/4 Watt,
5% tolerance, bent on .6 inch centers.
