Safety First!

Before connecting and using the

equipment, please read this Quick-Start Guide

carefully and keep it for future reference.

WARNING!

This equipment has been

designed to be installed by qualified

professionals only! There are many factors to

be considered when installing professional

sound reinforcement systems, including

mechanical and electrical considerations, as

well as acoustic coverage and performance.

Mackie Industrial strongly recommends that

this equipment be installed only by a

professional sound installer or contractor.

UP4000 Series

Power Amplifier

Quick-Start Guide

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/–20 dB

sensitivity switch.

Output modes include 4

Ω

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 LEDs or relays.

The UP4000 Series operates 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.

The

STAND BY

terminal is used to turn on

the amplifier with a remote switch.

Note:

Standby mode must first be

activated by moving a jumper (J1) on the

input board (standby mode is disabled by

default). See Figure 1 on back page.

When the POWER switch is turned on, the

amplifier goes into standby mode. In this

state, the amplifier is on but signal is not

allowed to pass. Shorting the STAND BY

terminal to the GND

terminal with an

external switch causes the amplifier to

become fully operational.

The

STANDBY GND

terminal on the

COMMANDS terminal strip is the common

connection point for STAND BY.

The

OVERL. 300mA

terminal is active

whenever the amplifier's overload

protection circuit is activated. This

provides 18 VDC with a maximum output

capacity of 300mA for driving an auxiliary

relay or indicating LED.

The

OVERL. GND

terminal on the

COMMANDS terminal strip is the common

connection point for OVERL. 300mA.

AC Protection Fuse protects the power

supply and amplifier circuitry. Replace

only with same type fuse.

Connect the supplied AC linecord to the

IEC AC Socket. The AC line fuse is

1. Never install, connect, or disconnect

the unit with the power supply on.

2. Before powering up the UP4000 Series

amplifier, make sure the voltage

selector switch on the rear panel

corresponds to the AC voltage applied.

3. Make sure the safety ground on the

power cord is properly grounded.

4. To prevent the risk of electric shock,

never open the unit. There are no

user-serviceable parts inside.

5. To ensure normal cooling of the

UP4000 Series, make sure the unit is

well-ventilated. Avoid exposure to direct

sunlight or proximity to any heat

source, dust, or dampness.

6. If installed in an equipment rack, provide

at least one rack space between each

integrated amplifier.

Replace only with same type fuse.

The

VOLTAGE SELECTOR

switch is used to

select the AC supply voltage for the

amplifier. Move switch so the AC line

voltage used appears on the switch

(DOWN for 115V, UP for 230V).

The

H.P.

switch activates a high-pass filter

on INPUTS 2-4, which attenuates

frequencies below 300Hz at 12 dB/octave.

The

L.P.

switch activates a low-pass filter

on INPUTS 2-4, which attenuates

frequencies above 7kHz at 12 dB/octave.

The

UNBALANCED IN

jack is an RCA-type

connector that can be used instead of the

BALANCED IN, or both can be used with

the PRIORITY function, which gives the

BALANCED IN priority over the

UNBALANCED IN.

The

PARALLEL OUT

jack is an RCA-type

connector that is in parallel with the

UNBALANCED IN jack for connecting to the

input of another power amplifier.

The

SENSITIVITY

switch adjusts the input

sensitivity of the UNBALANCED IN from 0

dB (typical line-level signals) to –20 dB

(for low-level signals).
