If you wish to derive more amplifier output power from a Zone 4P or 8P, it is possible to run pairs of Amp Outputs in Bridge Mode. This is suitable for running both low impedance and 70V line high impedance loudspeaker circuits up to 200W.
Bridge mode works across adjacent amplifier channels and is enabled in the odd numbered channel of the pair.
To enable, click Settings> Amp Outputs > Amp Output 1, 3, 5*, or 7*> Enable Bridge Mode
*Zone 8P only
A conformation dialog will be shown along with wiring diagram.
Take careful note of the loudspeaker wiring shown in the diagram - connect your loudspeakers accordingly.
Click Enable to turn on Bridge Mode.
Once enabled, all output processing settings are copied from the odd output (1, 3, 5, or 7) to the even output (2, 4, 6, or 8). Control of a bridged pair is done from the odd numbered channel.
The outputs are then treated as a pair until the bridge mode is disabled. To disable a bridged pair, first unplug your loudspeakers and click Disable Bridge Mode under Amp Output Settings. Click Disable when prompted by the conformation dialog.
Enabling bridge mode will allow you access to presets for loudspeakers not otherwise supported due to the power requirements to drive those loudspeakers. They are:
