Figure 2B Three-Channel Operation

To bridge the two channels, put the switch between the two input connectors in the “Bridged” position with the toggle switch pointing down.

In this configuration, connections to the speakers receiving the normal power feed from the unbridged channels should be made to the connectors for Channels One and Two in the normal fashion. That is, connect the wire running to each speaker to the appropriate output channel as marked. The “+” or “positive” connection goes to the top binding post with the red barrel. The “-” or “negative” connection goes to the bottom binding post with the black barrel.

The connection for the higher power, (bridged) channel should be following the connection diagram between the speaker connection binding posts for Channel Three and Four. Connect the “+” or positive connection going to the binding post marked “+” for Channel Three to the “+” or “red” terminal on the speaker. The connection going to the negative terminal on the speaker should be connected to the binding post marked “+” for Channel Four. (Figure 2B)

To complete the bridging of the circuits, use one of the jumpers packed with the

5.1to make a connection between the Negative (“-”) speaker connection terminals for Channel 3 and Channel 4 as shown in Figure 2B.

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

Two-Channel Operation:

In this mode two high-powered channels are provided for subwoofer use, or for high-powered conventional stereo applications. Using high quality interconnect cables, connect one output from your preamp or processor to the input connector marked “Channel One”, and the other to the input connector marked “Channel Three”. The input connectors for channels Two and Four are not used in this con- figuration. (Figure 2C)
