ENA2100-AC One Channel Mode

The ENA2100-AC Amplifier supports One Channel Mode.

When "One Channel mode" is activated, the two loudspeaker channels will play identical audio, and the audio will be in phase.
One can then choose to use two separate loudspeaker loops, each with maximum 100W, or one can bridge the two output channels, and use one loudspeaker loop with up to 200W load.

Configuration

One Channel Mode is configured in EMT.
Go to System -> ENA2100 -> Audio Line.
