place at four AMP 12-pin connectors mounted directly beneath the module
on the console mainframe’s bottom pan.

AMP B Connector — Control
The console’s on-air tally port is on the CRD-5 AMP B connector. This
is a simple relay closure that activates whenever programmed input
modules are turned ON (see page 2-4). The port can be used to control an
externally powered tally light that requires a continuous closure to
function.

Pin 12 – On-Air Tally Relay N.O.
Maximum current through
the on-air tally relay clo-
sure is 2 amps @30VDC.
