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.
