Note: If no page is heard,
refer to the troubleshooting
Guidelines.
8. Adjust sound levels using AmpliCenter controls, if necessary.
Using a small standard screwdriver, make the following adjustments (see Figure 8).
Figure 8. Test Page Adjustments
1. Adjust the Low Frequency Cut Off control. This control cuts out the low
frequency bass so that horns and small speakers are not over-driven and
distorted by excessive bass energy. Cut off frequency is continuously adjustable
from 50 Hz (full CCW rotation) to 400 Hz
(full CW rotation).
2. The Page VOX (voice activation) sensitivity is turned fully counter-
clockwise if the Dry Loop feature is not used.
3. Adjust Music Input Level. Clockwise rotation will increase the level. Listen and set
to a comfortable level.
4. Using a telephone from the host system, dial the paging extension.
Speak into the telephone in a normal manner. Your voice should be
heard from all connected speakers. the AmpliCenter Page input has an automatic
level control (ALC) which keeps loud voices and normal voices output at the same
level. Beware of paging from a telephone directly
under a loudspeaker; feedback howl can occur. (A feedback eliminator will solve
this problem).
5. Readjust Music input level to the desired loudness relative to Paging loudness.
6. Some loudspeaker taps may have to be readjusted to get even
coverage at all locations. be sure that the final speaker tap setting
totals do not exceed the power rating of the AmpliCenter.
7. Adjust Music Ducking level. this feature allows music to continue to be heard
during a Page, but at a reduced level. The range is from less than
40 dB (full CCW) to -6 dB (full CCW). If music-in is not connected, set to
full CCW.
