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”.

input allowing music, DVD sound or other audio source to be played through zones using the BUSS input. Additionally the
A 5020 Matrix Control Unit (available separately) can be connected to individual source inputs or the shared BUSS input. This
provides up to 8 audio program sources which can be easily switched via remote control or wallplate.
