STUDIO MODULE — LOGIC
This 14-pin connector has outputs for con-
trolling the studio warning lamp interface and
for lighting tallies when Dim, Mute, or talkback
are active. There are also remote mute and dim
inputs on the connector.
To activate the Remote Studio Dim (Pin 9)
and Remote Studio Mute (Pin 8) inputs, Pin
14 (Activate Logic Inputs) must be jumpered
to +5 to +40 volts. This voltage is normally sup-
plied from an external device when mute or dim
are actively controlled. If simple switches are
controlling the mute or dim then +5 VDC can
be supplied by Pin 7
