UNIVERSAL INPUT MODULE — MAIN LOGIC
The left connector connects to the A Input de-
vice; the right connector connects to the B Input
device.
Pins 15 and 20 have dual logic functions. With
the module set as a Mic Input (DS1 or DS3 switch
2, 3, 4, or 5 is set to ON) then pin 15 is a Logic
Active Tally and pin 20 is the Talk to Control Room
logic input. However, when the module is used as a
Line Input (DS1 or DS3 switches 2, 3, 4, and 5 all
set to OFF), then pin 15 is a Cue Tally output and
pin 20 is an external Cue command.
See pages 2-58 to 2-63
for examples of typical
logic connections.
