Figure 2C Two-Channel Operation

For two-channel use, make certain that BOTH bridging switches are engaged by switching them down, to the “bridged” position.

In the bridged mode, the connections to your speakers should be made using only the top row of binding post connections. Follow the connection diagram that is between the speaker connections. For the speaker connected to the Channel One input, connect the “+” terminal of the Channel One output to the wire going

to the “+” or red colored connection on your speaker. Connect the “+” terminal of the Channel Two output to the wire going to the “-” or black terminal of your speaker.

Repeat this procedure so that the input signal connected to the Channel Three input connector is connected to your speaker using the “+” speaker output con- nector of Channel Three as the “+” or “red” wire, and the “+” speaker output connector of Channel Four as the “-” or “black” wire.

To complete the bridging of the circuits, use the jumpers packed with the 5.1 to make a connection between the Negative (“-”) speaker connection terminals for Channel 1/Channel 2, and Channel 3/Channel 4 as shown in Figure 2C.

WARNING: The jumper connections should not be made when the amplifier is turned on. This connection must be made before operating the amplifier in a bridged mode.

Note: When using the 5.1 in a dual-bridged configuration, particularly with

4 ohm speaker loads, it will probably be necessary to provide additional cooling using a small fan. This cooling will also be needed in the dual-bridged mode if the amplifier is enclosed in a cabinet. Consult your dealer or custom installer for more information.
