ENA2x00-AC2 - One Channel Mode

The ENA2x00-AC2 Amplifiers 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, or one can bridge the two output channels, and use one loudspeaker loop.

When the ENA amplifier is used in "ICX-AlphaCom" mode you need amplifier license (1002600500 ILS-AMP) for one channel only.
