2.Connect the loudspeakers to the channel A and channel B SPEAKER OUTPUTS (8, 9). THE TOTAL SPEAKER LOAD MUST BE AT LEAST 4 OHMS PER CHANNEL FOR CHANNELS A AND B. If you try to operate at a lower impedance, the amplifier will overheat and then go into protection mode and stop operation until you correct the load conditions.

3.If you choose to use additional amplifiers, connect the additional amplifiers to the XPM-3000 using the LINE OUTPUT (1, 2) connectors.

4.Set the CROSSOVER SWITCH (3) to FULL RANGE so that the full range signal will go to the satellite channels (Channels A and B).

5.With the LEVEL CONTROLS (20, 21) of the channels set to zero (fully counterclockwise), turn the POWER (23) on. Apply a signal to the input of the amplifier. The level of the input signal should be as high as you will ever need it to be. This way, it will be as high above the amplifier’s noise floor as possible, ensuring an excellent performance and signal to noise ratio. Adjust the LEVEL CONTROLS for each channel to achieve the desired maximum listening level. Note, when the clip LEDs light, there is distortion present in the amplifier’s output section. If a clip LED 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.

Using the Signal 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 SIGNAL GROUND LIFT SWITCH (15) in the left position).

2.Then turn the power off before moving the SIGNAL GROUND LIFT SWITCH (15). Lift the ground by moving the SIGNAL GROUND LIFT SWITCH to the right, turn the power back on and listen to determine which position will provide a signal devoid of background noise and hum. Keep the SIGNAL GROUND LIFT SWITCH 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.
