background music source can be
a CD or tape player, AM, FM, or
commercial radio, orother audio
device.
Note: If more than one speaker cable
is routed to the AmpliCenter, a
connector block is necessary.
Refer to sample wiring diagrams on
page 8. It is recommended that
22GA shielded wire be used.
DO NOT hook up speaker wires with
AmpliCenter power plug connected!

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.

Troubleshooting
Some common problems encountered when the paging system is not operating are
described below. Check each item in the order listed.
1. No AC power to AmpliCenter.
2. Host telephone system failure.
3. Host system page port failure.
4. A hardwire disconnect between host system and PagePac®Plus.
5. AmpliCenter switch settings tampered with.
If the problem has not been resolved by checking the preceding items, follow the
steps described in Table 1.
Table 1. Troubleshooting Table
Problem Corrective Action
Page access from telephone system working, but page is
not heard. No power to AmpliCenter.
Host system not passing call through to AmpliCenter.
Telephone mode selection switch not set correctly for host telephone
system.
Ground start - Tip and Ring reversed or AmpliCenter not grounded.
Audio signal not reaching speakers. Check wiring at AmpliCenter. Verify
Page Accessed LED is on.
Background music cannot be heard. Input level not set correctly. Adjust music input level on AmpliCenter.
No power to music source. Verify power is on.
Radio off station. Adjust tuner.
Music input wires crossed, with signal grounded out.
Distorted, garbled, or raspy sound from all speakers
connected to AmpliCenter. Short circuited speaker leads. Separate.
Music input level too high. Turn down.
Speaker transformer shorted. Replace.
Failed AmpliCenter. Return for repair.
Green power LED off. AC outlet receptacle is not live. Check outlet circuit breaker or use another
outlet.
Power cord is loose.
Failed AmpliCenter. Return for repair.
Page access LED won’t go off. Page VOX too sensitive. Adjust.

Controls and Indicators, Terminals and Connectors
Figure 9 shows the controls and indicators, terminals and connectors on the rear
panel of the AmpliCenter. Table 2 identifies them by function.
Figure 9. AmpliCenter Controls and Indicators, Terminals and Connectors
Table 2. Controls and Indicators, Terminals and Connectors
1. AC Power in: 105 - 120 VAC, 210-240 VAC, 5OW Hz, (voltage auto-selectable within unit).
2. 0 dBm out, an auxiliary output that differs from the main 70.7V output in that it is a low level
(0 dB), 600 ohm balanced output used for driving a remote or off-premises amplifier.
3. DC Power, and 70V audio out to Controller (used only if Controller is also installed).
4. Low frequency cut-off screw-type adjustment pot. Attenuates low frequencies so that horns and small
speakers are not overdriven by excessive bass energy. Cut off frequency is adjustable from 50 Hz (full
CCW) to 400 Hz (full CCW).
5. Music In: left and/or right channels with ground.
Paging In: redundant paging input (ground, C1, tip, and ring).
70V Out: Balanced output used for terminating the loudspeaker wiring.
6. Screw adjustable potentiometers: VOX sensitivity level, Music ducking (mute level for music during
voice page). Music level for various music sources.
7. LEDs: Green - power on, lights when AC line voltage is applied to AmpliCenter.
Red - overload, lights when the AmpliCenter output exceeds its output power rating. This
can occur when total speaker load is greater than the output rating, or when speaker wiring
is shorted.
Red - unbalanced output, indicates when one speaker lead is accidentally shorted to ground.
Green - page accessed, lights when voice paging is active.
8. Telephone system mode switch: dry loop 600 ohms, dry loop Hi Z, ground start, or loop start.
9. Page input from host telephone system or Controller RJ11 connector: paging audio and control.

Connecting Speakers
1. Locate and mount all speakers in accordance with the floor plan drawing for
this installation.
2. Connect each speaker to the appropriate home run or speaker-to-speaker wiring
scheme as shown on the wiring plan (see Figure 10).
3. Test speaker wiring for short circuits.
Measure the resistance of each home run wire run with an ohmmeter. Any pair
indicating a value of less than 15 ohms must be rechecked for possible shorted
wiring or speakers. Correct any problems and retest.

Note: If paging zones use the
talkback feature (available only
when used with PagePac®Plus
Controller), cabling must be
shielded and grounded at the
AmpliCenter connector, not the
speaker. Maximum 2 speakers per
zone with talkback.

The Dry Loop 600 Ohm is a four wire interface consisting of a dry audio pair with a 600
Ohm impedance and a control pair. The page input is activated when the control pair receives
a contact closure from the host equipment, connecting Cl to ground. The Dry Loop page
input can also be activated by the presence of page input audio signals that exceed a set
threshold. This threshold is set by the page VOX adjustment; clockwise rotation lowers the
threshold and makes R more sensitive. Adjust by experimentation to account for various line
loss and noise. This feature is beneficial for (amplified) microphone sources that don't have a
Music/Page control contact, or for remote AmpliCenters.
Dry Loop Hi Impedance is used to interface with parallel multiple units. Input impedance
is 100K Ohms. Otherwise, the same as the 600 Ohm dry loop operation.
Note: Ground start interface
requires common ground
between paging input and
telephone system by direct
line or other common
grounding methods.
The Ground Start mode is a two wire interface and has a 600 Ohm input impedance. When a
trunk is accessed, a momentary ground is sent to the ringside of the pair by the host equipment,
loop current is detected and the tip-side of the pair is closed. Disconnect supervision of the
ground start mode is accomplished by monitoring the loop current.
The Loop Start mode is two wire interface and has a 600 Ohm input impedance. The host
equipment draws loop current from the talk-battery which is supplied by the AmpliCenter.
Disconnect supervision of the loop start mode is accomplished by monitoring the loop
current.
