Apply AC Power
Power to the PagePac controller, amplicenter, and zone expansion units,
is through a single power cord connected to the amplicenter. There is no
power switch.
Connect the 115 VAC modular connector to the back of amplicenter and
then to the outlet socket. Do not defeat the third wire ground circuit.
Audio Paging Zones
1.
Adjust the Low Frequency Cut-Off control. This control attenuates
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 50Hz (full CCW rotation)
to 400 Hz (full CW rotation).
2. The Page VOX 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 access
code. 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
talker’s and normal talker’s output at the same level. Beware of
paging from a telephone directly under a loudspeaker; feedback
howl can occur. (An anti-feedback speech processing unit or a
record/playback delay unit can solve this if it will be a problem for
the users.
5. Re-adjust Music Input level to the desired loudness relative to
Paging loudness.
6. Some loudspeaker taps may have to be re-adjusted to get even
coverage at all locations. Be sure that final speaker tap setting
totals do not exceed the power rating of the Amplicenter.
7. The Paging output is limited to a nominal 70 Volts rms by the ALC.
In a properly designed system, sound loudness is normally adjusted
by selection of appropriate speakers and their individual tap settings
for a 70 Volt input. However, circumstances such as a long term
change in ambient noise may call for reducing the loudness of all
speakers en-mass. This output level can be attenuated by an
overall Amplicenter output level control setting. This setting is
accomplished remotely from any host system phone that dials DTMF.
