CONNECTIONS

• Parallel (Mono) Mode

To put the amplifier in parallel-mono mode, first turn the amplifier off, then slide the MODE SELECTOR SWITCH (13) to the middle “PARALLEL (MONO)” position and properly connect the input wiring as shown. A signal into any input jack will drive both channels directly. You can patch the input signal on to any other amps using any of the remaining input jacks.

(Note: Do not connect a speaker load less than 2 ohms as it can damage your amplifier.)

[Note: Do not use the “PARALLEL (MONO)” switch when feeding the amp 2 separate signals.]

CHANNEL A

• Bridged Mono Mode

To put the amplifier in bridged mono mode, turn the amplifier off and slide the MODE SELECTOR SWITCH (13) toward the top “BRIDGED” position and properly connect the input/output wiring as shown. The signal is input into CH-A. Keep the level control of channel “B” turned completely down (counter clock wise).

(Note: Do not connect a speaker load of less than 4 ohms as it can damage your amplifier.)

(Note: This mode produces a large amount of power. Be sure that your wiring and speaker can handle it.)
