Based on multiple channels of the rugged ARX ‘ZR’ Series, these amplifiers are truly

the systems of the future!
They have everything you need to run either a complete sound system, in one

compact 2 RU package. Channel A and B, plus a powerful Sub channel. Award

winning ARX  ISC speaker processing is built in. Simply connect your mixer outputs

and your speaker leads and that's it - there’s nothing else to wire up!
The Rear Panel includes a choice of Balanced XLR or Jack inputs, and Neutrik

‘Speakon’ insulated speaker connectors for fast ‘plug and play’ setups.
There is also an Auxiliary input for the Sub channel, used when you do not need Sub

output. This means the Sub channel can then be used full range, typically for say, a

monitor system.
These amplifiers are further examples of the ARX commitment to produce amplifiers

that will survive the toughest musical environment, day after day, night after night,

because we know that audio professionals like yourself depend on them to earn a

living.

 

WARNING!

THERE ARE NO USER SERVICEABLE PARTS INSIDE THE
AMPLIFIER, SO PLEASE DON’T TAKE THE LID OFF AND POKE
AROUND!

Amplifiers run on DC voltages provided by the amplifier’s internal power

supply. These amplifiers have se and – DC fuses for both channels,

mounted internally on the power supply circuit board. The power Mosfets

used in the amplifiers are extremely rugged devices, and the correct rating

fuses in the power supply ensure that the amplifier circuitry is protected from

short circuit damage.
A blown DC fuse will be indicated by a very distorted low volume output

from that side of the amplifier.  A blown AC fuse will be indicated by nothing

working at all - check to see if the fans are turning.
Any blown fuse should be investigated. It doesn’t necessarily mean that

something is wrong with the amplifier, but indicates that there is something

wrong in the complete signal path, from the mixing console to the speakers.

If an AC fuse blows:

•  Switch the power off, replace the fuse with another of the same rating.
•  Switch the power back on.
•  If it blows again, switch the power off and disconnect the Input and

Speaker leads from the amplifier.  Replace the fuse with another of the same

rating.
•  If it doesn’t blow when you switch it back on, then the fault is somewhere

else.  Time to start checking those leads.
•  If the fuse does blow again, then contact your nearest  ARX service centre

or the dealer where you bought the amplifier.

If a DC fuse blows:

•  Get a qualified service person to inspect inside the amplifier. Please don’t

do it yourself! There are

 very 

dangerous voltages inside amplifiers, even

when they have been turned off!

Introduction

Thank you for choosing this ARX three channel power amplifier. We hope you enjoy

using it as much as we enjoyed creating it.  It is a precision engineered product

designed for professional use in all pro-audio applications, and as such, a working

knowledge of basic electronic safety procedures is assumed on the part of the

operator.
Like all ARX equipment, it has undergone extensive factory calibration, testing and

‘burn in’ before shipping. To ensure continued trouble free use, please familiarise

yourself with the contents of this manual before using.
