Intercom System Setting

Two independent intercom lines (producer line and engineer line) are selectable and available in this unit.
This unit supports 4-wire, RTS, and Clear-Com intercom systems. Make settings of the internal switches and menus
according to the system to be used.
Selecting Intercom System
Set the intercom system with SYSTEM I/F of the CCU CONFIGURATION menu (C06).
Select an intercom system (CLEAR COM, 4 WIRE, or RTS ) according to the system to be used.
Note
When intercom system is set to RTS or CLEAR COM be sure to connect the unit to the RTS or Clear-Com system.
Failure to do so will cause the output to oscillate and adversely affect the surrounding circuit.
