Red Light/Talkback Connector
The D25 fitted to the rear panel provides the connection for the red light switch contacts. It also provides input and
output signals for monitoring, talkback and signalling logic functions. See page 33 for connector pinout.
Refer to the diagram opposite for the equivalent logic functions for the signal inputs and outputs.
The contacts for the Red Light output are via a DIL relay and are rated as follows: 30Vdc, 25Vac, 100mA max. Do not use
t
he Red Light contacts to directly switch capacitive or reactive loads; always use an external relay with a suitable contact
rating.
Footswitch Connection
In addition to the logic functions provided in the above red light/talkback connector, two additional assignable inputs are
available on footswitch 1/4” jacks.
The jacks are mono circuits. The signals are activated by connecting the jack contacts together.
