OPERATING INSTRUCTIONS

The amplifier's power must be turned off when changing modes of operation.

Stereo Operation

The unit has two channels for stereo operation. Each channel provides a separate and
discrete signal at the speaker outputs according to the signal received at the input.

The following instructions are for 
applications with 8 Ohm, 4 Ohm or 
2 Ohm speakers of matched power
rating.

1.  With the power off, set the MODE
     SWITCH

2

to the STEREO 

     position. When the power is on, 
     be sure the Stereo LED on the
     front panel. If no, you have the switch in the wrong position. Correct it before contin-
     uing.

2.  With the power off, connect your input cables to the channel 1 and channel 2 inputs 
     using either the female  XLR INPUT JACK

1

or male XLR INPUT JACK

1

of 

     each channel. The other channel 1 & channel 2 input can be used to link to an 
     additional amplifier.

3.  Connect the loudspeakers to the channel 1 and channel 2 SPEAKERS OUTPUT

  (

6

.  THE TOTAL SPEAKER LOAD MUST BE AT LEAST 2 OHM PRE 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

14

of both channels set to zero

fully counterclo-

     ckwise

, turn the POWER SWITCH

8

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 in 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 LED's 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.
