The ZA series uses a toroidal transformer based Linear
Power Supply and new ‘state of the art’ Power Amplifier
Integrated Circuits, offering unprecedented amplifier
and load protection.
This is coupled with our ‘Headroom Enhance’ circuitry
based on our core ISC error correction technology,
developed by ARX and incorporated into all our Power
Amplifiers.
It provides maximum power output levels under all AC
mains supply voltages and rated load conditions, elimi-
nating Output Stage clipping.
Comprehensive Protection circuitry - a re-settable High
Current switched protection circuit instantly discon-
nects the speakers if a potentially damaging signal is
detected. New Input delay muting circuitry eliminates

Designed from the ground up using extensive computer
modelling and a compact, efficient toroidal transformer,
the ARX ZA series has been designed to satisfy the most
demanding professional applications.

The ARX ZA 600 is a 6 channel power amplifier, ideal for
any installation requiring multiple amplifier channels.
Individual pairs of channels can be switched to run as
single bridged mono channels for greater output into 8
ohm loads.
Our exclusive AutoLink design allows all 6 channels to be
linked as required.
Inserting a lead into Channel 1 input will automatically
route that signal to all the other channels as well.

However, if another lead is inserted into the Channel 3
Input, the link will break and start again, routing the new
signal to channels 3, 4, 5, and 6. Inserting another lead at,
say, Channel 5 will do the same.
In this way the ZA 600 can be easily and quickly config-
ured for single and multiple zones without requiring a
zone splitter.
Power Output is 100W RMS per channel/8 ohms, 125
W/4 ohms, and Bridged /8 ohms 250 W per channel pair
The ARX ZA 400 is an 4 channel power amplifier, ideal
for paging systems, Foreground and Background music
systems, A/V surround systems, Loudspeaker Multi-
Zoning and other installations requiring multiple amplifi-
er channels. Individual pairs of channels can be switched
to run as single bridged mono channels for greater
output into 8 ohm loads.
Our exclusive AutoLink design, first seen on the ARX
Multi Q parametric equalizer, allows all eight channels to
be linked as required.
Inserting a lead into Channel 1 input, for example, will
automatically route that signal to channels 2, 3, and 4 as
well.
However, if another lead is inserted into the Channel 3
Input, the link will break and start again, routing the new
signal to channels 3 and 4.
In this way the ZA 400 can be easily and quickly config-
ured for single and multiple zones without requiring a
zone splitter.
Power Output is 75W RMS per channel/8 ohms, 100 W/
4 ohms, and Bridged /8 ohms 200 W per channel pair
