The ARX ZA 800 is an all-new 8 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 8 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, 6, 7 and 8 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, 6, 7 and 8.
In this way the ZA 800 can be easily and quickly configured for single and multiple zones without requiring extra patch leads. Click Here for detailed information

New Technology Inside
For the ZA 800 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
The ZA 800 has a re-settable High Current switched protection circuit that instantly disconnects 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 ZA800 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!

Built to Last
Designed from the ground up using extensive computer modelling and a compact, efficient toroidal transformer, the ZA 800 has been designed to satisfy the most demanding professional applications. It is a distillation of our experience gained through years of making compact, powerful amplifiers.
