2. With the power off, connect your input cables to the CHANNEL 1 and 2

inputs using the 1/4" (1, 2,) or XLR (3, 4) INPUT JACKS of each channel.

3. Connect the loudspeakers to the CHANNEL 1 and CHANNEL 2

SPEAKER OUTPUTS (10, 12, or 13, 14). THE TOTAL SPEAKER LOAD

MUST BE AT LEAST 4 OHMS PER CHANNEL. If you try to operate at a

lower impedance, the amplifier will go into protection mode and stop

operation until you correct the load conditions.

4.

With the LEVEL CONTROLS (20. 21) of both channels set to zero (fully

counterclockwise), turn the POWER SWITCH (15) ON. With the level

controls of your MIXER or other INPUT device turned all the way DOWN,

turn the amplifier level controls all the way up for desired loudness from

your speakers.

Note, when the CLIP LED (19) light, there is distortion

present in the amplifier’s output section. If a CLIP LED (19) remains on or

flashes repeatedly, reduce the signal level by lowering the input level

control for the channel that is clipping or reduce the level at the source.

5. Now adjust your MIXER or other INPUT source to your desired listening

level. You also have the choice of keeping the volume of both speakers

equal, or for certain situations you can adjust the volume so one side

will be louder than the other.

PARALLEL MONO OPERATION:

Follow these instructions for PARALLEL MONO operation using a

single input cable, and you will have the same monophonic signal on

both the CHANNEL 1 and the CHANNEL 2 outputs. Each channel’s

output is controlled independently by that channel’s level control.

1. With the power OFF, set the OPERATION MODE SWITCH (5) to the

PARALLEL MONO position.

2. With the power OFF, connect your input cables to the CHANNEL 1 input

only using the INPUT JACK, 1/4" (1) or XLR (3) of CHANNEL 1.

3. Connect the loudspeakers to the CHANNEL 1 and CHANNEL 2

SPEAKER OUTPUTS (10, 12). THE TOTAL SPEAKER LOAD MUST BE

AT LEAST 4 OHMS PER CHANNEL. If you try to operate at less than 4

Ohms per channel, the amplifier will go into the protection mode and stop

operation until you correct the load conditions.

4. With the LEVEL CONTROLS (20. 21) of both channels set to zero (fully

counterclockwise), turn the POWER SWITCH (15) ON. With the level

controls of your MIXER or other INPUT device turned all the way DOWN,

turn the amplifier level controls all the way up for desired loudness from

your speakers. Note, when the CLIP LED (19) light, there is distortion

present in the amplifier’s output section. If a CLIP LED (19) remains on or

flashes repeatedly, reduce the signal level by lowering the input level

control for the channel that is clipping or reduce the level at the source.

5. Now adjust your MIXER or other INPUT source to your desired listening

level. You also have the choice of keeping the volume of both speakers

equal, or for certain situations you can adjust the volume so one side

will be louder than the other.

MONO BRIDGE OPERATION:

Follow these instructions to bridge the unit’s output. Bridging the

amplifier converts the unit to a monophonic or single channel amplifier.

The amplifier can be used with 8 Ohm or higher loads only in MONO

BRIDGE mode. This mode is used to provide a higher voltage with

greater headroom to your speaker. Before setting your amplifier for

MONO BRIDGE operation, make sure that your speaker can handle the

high power level provided by the amplifier in MONO BRIDGE mode.

CAUTION: VOLTAGE OVER 100 VOLTS MAY BE PRODUCED AT THE BRIDGE OUTPUT

TERMINALS IN THIS MODE.

1. With the power off, set the OPERATION MODE SWITCH (5) to the

BRIDGE position.

2. With the power off, connect your input cables to CHANNEL 1 input only

using the INPUT JACK, 1/4" (1) or XLR (3) of CHANNEL 1.

3. Connect the loudspeaker to the BRIDGE SPEAKER OUTPUT (11) only.

Be sure the polarity of your connection is correct. The total speaker load

must be at least 8 Ohms or above. If you try to operate at less than 8

Ohms in the MONO BRIDGE mode, the amplifier will go into the

protection mode and stop operation until you correct the load conditions.

4. With the CHANNEL 1 LEVEL CONTROL (20) set to zero (fully

counterclockwise), turn the POWER SWITCH (15) ON. With the level

controls of your MIXER or other INPUT device turned all the way DOWN,

turn the amplifier level control all the way up for desired loudness from

your speakers. Note, when the CLIP LED (19) light, there is distortion

present in the amplifier’s output section. If a CLIP LED (19) remains on or

flashes repeatedly, reduce the signal level by lowering the input level

control for the channel that is clipping or reduce the level at the source.

5. Now adjust your MIXER or other INPUT source to your desired listening

level. You also have the choice of keeping the volume of both speakers

equal, or for certain situations you can adjust the volume so one side

will be louder than the other.

USING THE GROUND LIFT SWITCH:

Depending on your system configuration, sometimes applying the

ground will create a quieter signal path. Sometimes lifting the ground

can eliminate ground loops and hum to create a quieter signal path.

1. With the power amp on, listen to the system in idle mode (no signal present)

with the ground applied (the GROUND LIFT SWITCH (6) in the left position).

2. Turn the power off before moving the GROUND LIFT SWITCH (6). Lift the

ground by moving the GROUND LIFT SWITCH (6) to the right, turn the power

back on and listen to determine which position will provide a signal free of

background noise and hum. Keep the GROUND LIFT SWITCH (6) in the

ground position if the noise level remains the same in either position.

CAUTION: DO NOT TERMINATE THE AC GROUND ON THE POWER AMPLIFIER IN ANY WAY.

TERMINATION OF THE AC GROUND CAN BE HAZARDOUS.
