The ARX ZA 600 is an all-new 6 channel power amplifier, ideal for paging systems, Foreground and Background music systems, A/V surround systems, Loudspeaker Multi-Zoning and other installations 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. The ZAT 6 line transformer unit is available for applications requiring 100V/70V line operation

‘AutoLink’™ Input Looping
Our exclusive AutoLink design, first seen on the ARX Multi Q parametric equalizer, allows all six channels to be linked as required.
Inserting a lead into Channel 1 input, for example, will automatically route that signal to channels 2, 3, 4, 5 and 6 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.
In this way the ZA 600 can be easily and quickly configured for single and multiple zones without requiring extra patch leads.

New Technology Inside
In the ZA 600, ARX design engineers have chosen a conventional toroidal transformer based Linear Power Supply coupled with ‘Headroom Enhance’ circuitry based on our core ISC error correction technology. ISC (Interactive System Control) was developed by ARX for our range of Concert Series Loudspeaker Processors, and is now incorporated into all our Power Amplifiers and the SPL range of Integrated Powered Loudspeakers.
It provides maximum power output levels under all AC mains supply voltages and rated load conditions, eliminating Output Stage clipping.

Comprehensive Protection circuitry onboard
Over the years ARX engineers have done intensive research into amplifier protection systems. The ZA 600 has a re-settable High Current switched protection circuit that instantly disconnect the speakers when a potentially damaging signal is detected.

New Input delay muting circuitry eliminates switch on/switch off noise.

Safety First
The outputs are all fully isolated Speakon connectors, in keeping with all current Worldwide approval requirements for amplifier output connections. There are no bare Input or Output terminals, or low cost ‘push terminals’ used on this Professional product

Rear panel accessible multi turn level controls make the ZA600 ideal for installation applications where tamper-proof operation is required.

Note that the amplifiers are shipped with the level controls set at full on (no attenuation). Care should be taken setting initial levels during system turn on!

Input Connectors
Balanced Jack wired: Tip + Hot, Ring – Cold, Sleeve Audio Ground; AutoLink input looping
Bridged Mono mode
Individual pairs of channels can be switched to single bridged mono channels for greater output into 8 ohms
Output Connectors
Neutrik Speakon, wired as follows:
Connector 1 - Channel 1 (1+, 1–), Channel 2 (2+, 2–)
Connector 2 - Channel 3 (1+, 1–), Channel 4 (2+, 2–)
Connector 3 - Channel 5 (1+, 1–), Channel 6 (2+, 2–)
Each chassis connector supplies two output channels - 1 and 2, 3 and 4, 5 and 6. The line connectors should be wired with Pins 1+ and 1- for the odd numbered outputs, and 2+ and 2- for the evens.
A connector for a bridged output should be wired Pin 1+ and Pin 2+ ONLY. In a bridged configuration Pin 1+ will be the positive (+) terminal of the pair, and Pin 2+ will be the negative (-)
