Combine/Isolate Switch: When in the Combine position, the unit will combine the audio signals of the two channels
to create a single audio channel where all users can intercommunicate. When in the Isolate position, the unit will cre-
ate two groups of completely independent users.
2.
Channel Status Indicators: The indicators are green for normal operation and red when there is an overload or short
circuit. The circuitry in the unit will automatically reset when the overload or short circuit is located and fixed.
3.
Universal AC Power Input: The unit accepts any input power in the range of 100-240 VAC, 50/60 Hz.

Intercom Channel Connectors: When the Combine/Isolate switch is set to the Isolate position, each channel
connector is powered separately and has completely separate intercom audio. When the Combine/Isolate switch is set
to the Combine position, each channel is still powered separately, but the audio signals are combined so that all users
on both channels can intercommunicate.
5.
