PROART A 5024 Operating Instructions Manual

A 5024 Multi-Zone Amplifier

Operating Instructions

Overview

Congratulations on purchasing the A 5024 multichannel
amplifier. It is suitable as a stand alone system for multi
room (multi zone) installations, or for connection to an
A 5020 matrix controller for more advanced audio
switching (contact your dealer for more information on
the A 5020).

The A 5024 provides up to 6 stereo speaker zones or 12
mono speaker zones or a combination of both.

Each zone can be configured to accept either a dedicated,
or common input source.

Any combination can be used allowing for instance
background music to be playing in dining room & enter­taining areas while home theatre effects are playing in
the lounge.

The BUSS input is best used when it is connected to an
audio switching device such as a home theatre receiver.
This allows you to quickly switch audio sources across
multiple zones at once.

Features

• 6 stereo speaker zones or 12 mono speaker zones or a

combination of both. Each rated at 40W into 8Ω
speakers.

• Each pair of amplifiers are bridgeable delivering

120W into 8Ω.

• Each amplifier has a choice between shared BUSS or

individual zone inputs.

• Common BUSS output allows infinite number of

amplifiers to be used.

• The unit can be powered up via signal detection or

external trigger (5-24V DC).

• Signal LED for each channel

• Amplifier “protect” LED per amplifier pair

• 12 individual volume controls

• Input signal limiter.

Installation

The amplifier can be configured in a number of different
configurations. Please consult the configuration dia­grams on pages 2, 3 & 4 as a guide for setting up your
system.

SYSTEM OPERATION

This system can be configured to operate in 3 differ­ent modes. These are selected via the rear mounted
3 position power switch, marked ON, Auto, 5-24V.

The front mounted power rocker ON/OFF switch
must be ON for any of these modes to operate.

ON Mode:

All amplifiers are permanently ON regardless of
any signal applied.

Auto Mode:

The appropriate amplifiers automatically switch
ON, only when an input signal is present. This
saves power and uneccessary heat build up.

5-24V Mode:

Applying 5-24VDC to the trigger terminals switches
all amplifiers ON. This is useful for when the ampli­fier is located in a remote, difficult to access location
ie: ceiling.

OTHER FEATURES

Protection LEDs

Within 1 – 2 seconds after switch on the PROTECT
LEDs will turn green indicating normal operation.
If there is an amplifier over-load the PROTECT
LEDs will turn red indicating a fault.

Trigger Input / Output

The trigger terminals can be used to turn the ampli­fier on via a remote switch or external controller.
See figure 2 for examples of how this feature can be
used.

Amplifier Bridging

For speakers requiring extra power 2 channels may
be bridged to provide a single mono 120W RMS
channel.

When using this configuration ensure input source
is connected to the RCA labelled “bridged”.
