VOICE PRIORITY ADJUSTMENT

The amplifier has an internal adjustment potentiometer

(on the front circuit board) which allows you to set the level at

which the voice priority circuit activates.

For example, suppose that only loud talking into a paging

microphone (on Input 1) will mute the auxilliary music. This

pot can adjust the voice priority sensitivity until it takes only

moderate or low volumes to mute the aux music.

Please note that the following adjustment requires that

the top cover be removed, therefore this procedure

is for qualified and experienced electronics technicians

only, carefully trained in all aspects of ESD (electro-static

discharge) precautions and electronics safety.

1. Make sure the unit is switched off, and that the power

supply cord and all other cords are removed.

2. Undo the top cover screws and remove the top cover.

3. Look at the top edge of the front panel circuit board. Just

above the INPUT 2 Level control, you will see a small

potentiometer, VR102.

4. Using an insulated small phillips screwdriver, gently rotate

this pot to change the sensitivity (clockwise for more

sensitivity, i.e., less intense signals will mute the aux. The

pot can be reached from the top by passing the screwdriver

between the front panel top edge and the metal chassis.

5. The voice priority can also be disabled by removing the

small jumper next to the pot. You will need a good pair of

needle-nosed pliers, or remove the front panel circuit board

from the front panel by pulling off all the plastic knobs and

undoing the hex nuts on each level control.

6. When finished, recheck your work, and replace the top

cover. Verify that Input 1 or the Telephone paging suitably

mute the Aux and other inputs, without having to shout.
