‘Every day, ARX Pro

Audio products

solve problems for

thousands of peo-

ple around the

world.

Audio is all we do...

and we do it well!’

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

The ARX ZA 5:1 power amplifier has been designed

specifically to meet the ever-increasing demand for high

quality surround sound amplification, especially in the

demanding corporate A/V market.

The Left, Centre, Right, Rear Left, Rear Right Channels

each deliver 100 watts @ 4 ohms, while Channel 6 offers

a high current output of 240 watts @ 4 ohms for the most

demanding sub-woofer applications.

Channel 6 features its own fully independent power

supply to eliminate Low Frequency power modulation of

Channels 1 - 5, a common design flaw in lesser surround

amplifiers, and ensures that ample high level Low Fre-

quency amplification is always available.
