designed for continuous duty in speech, music,
paging, and sound reinforcement applications in
churches, schools, offices, and other venues
demanding high performance, flexible features, and
rugged dependability.

Balanced and Unbalanced Inputs
Balanced Input Priority Function
Unbalanced Line-Level Output
Two discrete inputs with priority are provided.
The main program input is actively balanced and
terminated to a barrier strip connection on the rear
panel. The second input is unbalanced and terminated
to a single RCA connector. A contact closure will give
priority to the balanced input by muting the
unbalanced input. The unbalanced input features a
parallel output and 0 dB/20 dB sensitivity switch.
Output modes include 4Ω constant impedance
and 25V, 50V, 70V, and 100V constant voltage. The
smart output stage is fully protected against
permanent damage caused by overloading, shorts,
and extreme temperatures. Activation of the
overload protection circuit turns on 18 VDC (300mA)
power at a barrier connector on the rear panel, which
may be used to drive a relay or indicating LED. The
UP4000 Series will operate on either 115 VAC or
230 VAC, 50/60Hz, as determined by the Voltage
Selector switch, and supplied by a detachable IEC
power cord. Insulated terminals to connect a backup
24 VDC battery are provided on the rear panel.
Switchover to DC is automatic. A programmable
stand-by mode allows the amplifier to be turned on
remotely with a contact closure.

LOW EQ is a shelving filter that provides 12 dB
of boost and cut below 100Hz.
POWER INPUT provides a means to connect an
external 24 VDC power supply or battery as an
alternative or backup power source. The UP4000
Series seamlessly switches to the backup supply if
there's an AC power loss. When both AC power
and 24 VDC power are connected, the DC power is
switched off.

The STD-BY indicator lights when the amplifier is
in standby mode.
Note: Standby mode is disabled by default. An
internal jumper (J1 on the input board) must be
changed to enable standby mode. See "Internal
Settings" on page 8.
POWER OUTPUTS are screw-terminal
connections for connecting speakers to the 4-ohm,
25V, 50V, 70V, or 100V outputs.
WARNING: To prevent the risk of electric shock,
never touch the bare wires coming from the output
terminals of the amplifier when it is switched on.
When all connections have been made, insulate the
output terminals of the amplifier using the
protective cover provided.
The OVERLOAD indicator lights when the
amplifier is operating in overload, a condition
generally caused by a problem on the speaker line.
When the amplifier is switched on, the OVERLOAD
light comes on for a few seconds. This is normal
and does not indicate a problem.

Constant-Voltage Output
In a constant-voltage system, each speaker must
be equipped with a line transformer having an
input voltage equal to that of the line (e.g., 25V,
50V, 70V, or 100V). Typically, these line trans-
formers have selectable power taps (i.e., 2.5W,
5W, 10W) for connecting to the constant-voltage
line. CAUTION: The sum of the wattage values
of the speakers must not exceed the output
power of the amplifier.

Note: This illustration demonstrates a typical application using a pair of UP4000 Series Power
Amplifiers. A paging microphone and a jukebox are connected to the Balanced Input of Amp 1 via the
Mixer, and the Input priority function can be switch-activated to give the paging mic and jukebox priority
over the signal source connected to the Unbalanced Input. A preamplifier is connected to the Unbalanced
Input, with source selections for an AM/FM Tuner, Cassette or DAT Recorder, and CD Player. The Parallel
Out is connected to the Unbalanced Input on a second UP4000 Series. 70V constant-voltage speakers
are connected to the 70V tap on Amp 1, and a pair of 8-ohm speakers (connected in parallel for a total
impedance of 4 ohms) are connected to the 4Ω tap on Amp 2.
UP4000 – 6
Connecting the UNBALANCED IN
The UNBALANCED IN uses an RCA-type
connector. It accepts a line-level signal (–10 dBV)
with the SENSITIVITY switch in the 0 dB position
(pushed IN). When connecting a low-level signal,
push the SENSITIVITY switch OUT (20 dB position).
Use high-quality, two-conductor shielded cable to
make these connections.
Connections
Connecting the INPUT
The Input has a balanced screw terminal
connector that accepts a line-level signal. The screw
terminals should be connected as shown in the
following figure:

+
Connecting the Speakers
The speaker output connectors are screw
terminals. Use 16 or 18 gauge wire for connecting
the amplifier outputs to the speakers. Strip the wire
back about 1/2" inch, loosen the screw enough to
loop the wire around the shaft of the screw
(clockwise), and tighten down the screw with a slot-
head screwdriver.

INPUT Terminal Strip: Balanced Connection
If using a constant-voltage distributed speaker
system, connect either the 25V, 50V, 70V, or 100V
output terminal to the "+" side of the speaker system,
and connect the "0" output terminal to the "–" side of
the speaker system. Make sure that the taps on the
speakers add up to no more than the rated power
for the UP4000 Series Amplifier being used.
Strip the wire back about 1/2" inch, loosen the
screw enough to loop the wire around the shaft of
the screw (clockwise), and tighten down the screw
with either a slot-head or phillips-head screwdriver.
Use high-quality, three-conductor shielded cable
for balanced connections. The better the shield, the
better the audio signal is protected from induced
EMI and RFI.
CAUTION: To prevent the risk of electric
shock, never touch the bare wires coming
from the OUTPUT TERMINALS of the
amplifier when it is switched on.
If connecting an unbalanced line-level signal to
the Input, wire the connections as shown in the

Internal Settings
Thermal Considerations
There is one setting that can be changed inside
the UP4000 Series Amplifier. This setting should be
made prior to installation.
IMPORTANT: The UP4000 Series amplifier is
convection cooled rather than fan cooled. Heat is
drawn away from the amplifier by the heatsink and
radiated through the cooling vents in the top cover.
When installing the UP4000 Series, be sure to
allow sufficient air space around the top and rear of
the amplifier to allow adequate cooling for the
heatsink. Leave at least one rack space above and
below the UP4000 and at least 6 inches behind the
chassis to allow proper ventilation.
CAUTION: These servicing instructions
are for use by qualified personnel only. To
avoid electric shock, do not perform any
servicing other than that contained in the Operating
Instructions unless you are qualified to do so.
Refer all servicing to qualified service personnel.
Make sure the power is off and the power cord
disconnected before removing the top cover to gain
access to the inside of the UP4000 Series.
If the amplifier should overheat, a thermal
switch is activated that turns off the power
amplifier, allowing the heatsinks to cool down. The
ON indicator on the front panel will remain lit. Once
the amplifier has cooled to a safe operating
temperature, the thermal switch resets and
reactivates the amplifier. If this should occur,
identify the cause of the problem and take
corrective action (i.e.,

An external normally-open switch can be
connected between the STANDBY terminal and the
GND terminal on the COMMANDS barrier strip on the
rear panel. Closing the switch enables the signal to
pass through the amplifier, and opening the switch puts
the amplifier in standby mode (power on, no signal).
Note: The UP4000 Series is shipped with the
Standby Mode disabled. Move jumper J1 on the
input board to enable the Standby Mode (see
instructions on page 8).
Using the BALANCED IN
The BALANCED IN accepts a line-level signal.
Connect the input source to the BALANCED IN
barrier strip screw terminals.
PRIORITY Function
The BALANCED IN has priority over the
UNBALANCED IN. The priority function can be
activated by connecting a normally-open switch
between the input PRIORITY terminal and the GND
terminal on the INPUT barrier strip on the rear
panel. Closing the switch activates the priority

Using the UNBALANCED IN
The UNBALANCED IN accepts either a line-level
signal (0 dB position) or a low-level signal (20 dB
position), using the input SENSITIVITY switch.
POWER OUTPUTs
The amplifier outputs on the UP4000 Series can
be used with a 4-ohm impedance load, or to directly
drive a 25V, 50V, 70V, or 100V distributed system
(constant-voltage system).
High-Pass Filter
Push in the H.P. switch to engage the high-pass
filter, which rolls off frequencies below 300Hz at
12 dB/octave.
Low-Pass Filter
Direct Speaker Connection
Push in the L.P. switch to engage the low-pass
filter, which rolls off frequencies above 7kHz at
12 dB/octave.
If the UP4000 Series is not being used in a
distributed speaker system, you can connect a
speaker with a 4-ohm load between the "4Ω"
terminal and the "0" terminal.
Note: The H.P. and L.P. filters affect both the
balanced and unbalanced inputs.
Distributed Speaker System
Using the PARALLEL OUT
When using the UP4000 Series in a distributed
system, connect the distributed system between
the appropriate POWER OUTPUT terminal (25V, 50V,
70V, or 100V) and the "0" terminal. Make sure the
speakers in the system are tapped appropriately so
they do not exceed the rated power of the amplifier.
(AM4060 = 60 watts, AM4120 = 120 watts,
AM4160 = 160 watts).
The PARALLEL OUT connector is provided to
connect the UNBALANCED IN signal to multiple
amplifiers in a daisy-chain configuration.

power supply for the UP4000 Series, or as a
backup supply in case of an AC power failure. The
UP4000 Series seamlessly switches to the backup
supply if there is a power loss. When both AC power
and 24 VDC power are connected, the AC power is
used and no current is drawn from the DC supply.
