Wiring

STEREO (DUAL) WIRING USING THE SPEAKON® CONNECTORS
1. See On the back panel, set the Output Mode Switch to STEREO.
2. Wire the speakers to the Speakon® connectors as shown.
STEREO (DUAL) WIRING USING THE BINDING POST CONNECTORS
1. See On the back panel, set the Output Mode Switch to STEREO.
2. Wire the speakers to the binding post connectors as shown.

BRIDGE-MONO WIRING USING THE SPEAKON® CONNECTORS
Bridge-mono mode doubles the output power of the amplifier.
1. See On the back panel, set the Output Mode Switch to BRIDGE.
2. Wire the speaker to the Speakon® connector as shown.
3. Only the Channel 1 Volume Control works in Bridge-mono mode.

BRIDGE-MONO WIRING USING THE BINDING POST CONNECTORS
Bridge-mono mode doubles the output power of the amplifier.
1. See  On the back panel, set the Output Mode Switch to BRIDGE.
2. Wire the speaker to the Binding Post connectors as shown.
3. Only the Channel 1 Volume Control works in Bridge-mono mode.

PARALLEL WIRING USING THE SPEAKON® CONNECTORS
With this wiring, a signal sent to Channel 1 is paralleled to both channels so that it is reproduced by both speakers.
1. See . On the back panel, set the Output Mode Switch to PARALLEL.
2. Wire the speakers to the Speakon® connectors as shown

PARALLEL WIRING USING THE BINDING POST CONNECTORS
With this wiring, a signal sent to Channel 1 is paralleled to both channels so that it is reproduced by both speakers.
1. See On the back panel, set the Output Mode Switch to PARALLEL.
2. Wire the speakers to the binding post connectors as shown.
