place at two DB-25 multi-pin connectors mounted directly beneath the
module on the console mainframe’s bottom pan.

are +4dBu balanced, analog stereo.

Upper DB-25 Connector — Control
The console’s on-air tally port is on the CRD-500 upper DB-25
connector. This is a simple relay closure that activates whenever pro-
grammed input modules are turned ON (see page 2-4). The port can be
used to control an externally powered tally light that requires a continu-
ous closure to function.
Pin 14 – On-Air Tally Relay COM
Pin 1 – On-Air Tally Relay N.O.
Maximum current through
the on-air tally relay clo-
sure is 2 amps @30VDC.
