TEL Volume Control
The TEL VOLUME control on the rear panel adjusts the TEL input’s paging
level. It does not affect the microphone level. Rotate the control counter-
clockwise to decrease the level. Rotate the control clockwise to increase the
level.
VOX SENSitivity Control
When an input signal (such as voice) is detected through the TEL input, the
music channels (AUX1 and AUX2) will be muted.The VOX SENSitivity con-
trol should be set so that only the desired signal is above the threshold level,
while noise and unwanted signal is below it.To adjust the sensitivity of this cir-
cuit:
1. Rotate the control fully clockwise. While making a page announcement
and talking at a low level, the sound should not be choppy nor missing
parts of words. If it is choppy, or if intelligibility is poor, rotate the control
counterclockwise to the point where the sound is clear and crisp (but
not to the maximum counterclockwise position).
2. If the background music shuts down when no page is in progress, rotate
the control clockwise until the music is restored.
