FUNCTIONAL DESCRIPTION OF CONNECTION
A pair of Normally Open (N/O) relay contacts. A “dry contact closure” between the pins is generated each time
the studio has a live mic.
CV logic to this input to enable the active low inputs: Mute and Dim Studio. If the inputs are isolated
from other devices (e.g., on a remote control panel), the +VDC can come from Logic 5 Logic.
When pulled low, mutes the studio MONITOR output.
When pulled low, dims the studio MONITOR output by 12 dB.
Normally Open (N/O) contact output. A “contact closure” to Tallies Common (pin 10) is generated while any
location talks to the Co-Host.
Normally Open (N/O) contact output. A “contact closure” to Tallies Common (pin 10) is generated when the
studio MONITOR output is muted.
Normally Open (N/O) contact output. A “contact closure” to Tallies Common (pin 10) is generated when the
studio MONITOR output is dimmed.
The Common (C) contact output for the Mute, Dim, and Talk to Co-Host Tally outputs.
Module logic voltage output source that can deliver up to 300 mA of current to an isolated control panel.
Outputs are paralleled for convenience.
Module logic ground for isolated control panels only.
