1Bus 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.

2Line 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.

3Line/Bus Switch: Sets the zone input to the Line audio input or the Bus input.

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

5Gain 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.

6Power 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.

7Fuse Receptacle: Holds a replaceable fuse for AC power input connection. Fuse rating for North America and Europe is T10AL 250V.

AC Input: The AC voltage input for the North

8American model is 120VAC at 60Hz (for the European model, 230VAC at 50Hz). This receptacle accepts a 3-prong IEC 320 type connector. A detachable 3-terminal power cord is included.

12VDC Trigger In/Out: The 12V Trigger In is

9used 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.

Delay Time: Muting delay can be adjusted from

10about 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.
