Loop Field
Use the Loop field to configure a pair of ports to act as a loop in and loop out connectors. CH
B can be configured as a loop out connector for CH A. Additionally; CH D can be configured as
a loop out connector for CH C.
Configuring a pair of connectors for looping allows greater flexibility when installing the 2-Wire
wiring.

Notice!
When XLR-A and XLR-B are looped, this means both connectors are supporting the same pair
of RTS-1 and RTS 2 channels and these ports to the intercom are port CH A and port CH B.
Auto-Mute Field
Use the Auto-Mute field to determine whether the 2W port automatically mutes. If the setting
is enabled, the 2W port is muted whenever OMS detects the absence of DC power on the line
(typically, because the cable on the 2W port was removed).
By default, the Auto-Mute is enabled.
