2. INTRODUCTION

The UP4000 Series Power Amplifiers are
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.

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.

The front panel provides a Master volume control,
and Low and High EQ controls. The control knobs
can be removed for security, and their recessed
shafts covered with the supplied inserts. LEDs
indicate power, stand-by mode, signal present at
the output, peak, and output overload. 12 dB/octave
Low and High shelving equalization with up to 12 dB
of boost or cut at 100Hz and 10kHz can be applied
to the output signal.

Accessories include a rack mounting kit.

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.

Note: The unit is not equipped with battery charging
capability.

The

D.C. FUSE

the amplifier circuit. Replace with the same type
fuse only.

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.

Constant-Impedance Output

The total impedance of the speakers and cable
connected to the "4Ω" constant-impedance output
should be 4 ohms. Connect the "4Ω" terminal to
the "+" (HIGH) speaker terminal, and the "0"
terminal to the "–" (LOW) speaker terminal.

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 trans­formers 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.

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 slot­head screwdriver.

If using a 4-ohm speaker, connect the 4Ω output
terminal to the "+" terminal on the speaker, and
connect the "0" output terminal to the "–" terminal
on the speaker.

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.

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.

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.

STANDBY MODE

Jumper J1 on the input board allows you to
enable the Standby function. Standby mode is
disabled by default. You must change jumper J1 on
the input board to enable the Standby function.

UP4000 SERIES

INPUT BOARD

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.

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.,
provide better
ventilation, install a fan
in the rack, make sure
the amplifier is not
overloaded by too low

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).

Direct Speaker Connection

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.

speakers in the system are tapped appropriately so
they do not exceed the rated power of the amplifier.

POWER INPUT 24V D.C.

The UP4000 Series can be powered using a 24
VDC power supply. This can serve as the primary
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.

Note: The unit is not equipped with battery
charging capability.
