BRIDGED OPERATION
The amplifier can be operated as a single, mono amplifier with more power than either
single channel in stereo mode. To enable mono bridged operation, the MODE button (6) on
the rear panel must be set to the BRIDGE position (in). When in mono mode, the amplifier
uses the CH1 input jacks and level control, although each channel retains its own
protection modes. Mono bridged mode supports speaker loads down to 4 ohms.
Unlike stereo operation, which uses each channel's output connectors to connect the
speakers, mono bridge operation uses a single pin from each output connector to connect
the speaker. When in mono bridged mode, connect the positive pin on the channel 1
output connector to the speaker's positive connection and the positive pin on the channel
2 output connector to the speaker's negative connection.
Following is a sample connection diagram for using a single 605030 amplifier for mono
bridged operation to drive a single speaker, such as a subwoofer.
