ENA2100 - One Channel Mode
From Zenitel Wiki
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.
Wiring
The bridging of loudspeaker channels must be done by the installer, by shorting wires on the rear connector, or at external terminal blocks.
In case of 100V line:
- Short "Com"-terminal for Ch1 to "Com"-terminal for Ch2.
- Short "100V"-terminal for Ch1 to "100V"-terminal for Ch2.
In case of 70V line:
- Short "Com"-terminal for Ch1 to "Com"-terminal for Ch2.
- Short "70V"-terminal for Ch1 to "70V"-terminal for Ch2.
Status LED
There is a green LED inside the Amplifier, right behind the loudspeaker connector, which will turn ON when "One Channel mode" is active. The LED can be seen through the rear grille.
It is recommended to check that the "OneChannel-LED" is turned ON before bridging the two channels.
Additional information
When One Channel mode is used, you need amplifier license for one channel only.
"One Channel" mode is the same as "Mirror CH1 audio" in the ENA2200 and ENA2400 amplifiers.
