Bus Input/Output: The bus line input is an optional input that can be used to connect a single source to multiple zones. The bus line output is a passive passthrough of the bus input and can be used to daisy chain the source to other amplifiers in the system.

Line Input: The line audio input for each zone is a dedicated sensing input that will activate the zone when an audio signal from a source is present.

Fuse Receptacle: Holds a replaceable fuse for AC power input connection. Fuse rating for North America is T10AL 250V and for Europe is T7AL 250V.

AC Input: The AC voltage input for the North American model is 120VAC at 60Hz (European model, 230VAC at 50Hz). This receptacle accepts a 3-prong IEC 320 type connector. A detachable 3- terminal power cord is included.

Line/Bus Switch: Sets the zone input to the Line Input or the Bus Input.

Speaker Outputs: The A and B speaker outputs are in parallel to the zone amplifier output. The mini- mum speaker impedance for stereo mode opera- tion is 4 ohms for one pair and 8 ohms for two pairs of speakers. The minimum impedance for bridged mode operation is 8 ohms, Speaker B only.

Gain Controls: Left and Right gain controls inde- pendently adjust the sound level for each channel. When used in the bridged mode only the Left con- trol is used.

Power Switch: Turns the amplifier on/off. This switch does not disconnect the main power feed from the amplifier; this requires that the power cord be unplugged from the outlet.

912VDC Trigger In/Out: The 12V Trigger In is used to activate the zone. The Trigger Out provides 100mA 12V max. This can be used to drive other 12V triggered devices. The delay and audio sensing are bypassed when the 12V trigger input is used.

10Delay Time: Muting delay can be adjusted from about 0.5 minute to 4.5 minutes. When an audio signal is not present, the amplifier will automatically go into standby mode after the preset period of time. When set to maximum, the amplifier will stay active and not go into standby.

11Stereo/Bridge Mono Switch: Sets each zone amplifier for stereo or bridged mono operation.
