IMPORTANT - PLEASE READ THIS FIRST

This is a dual voltage unit. It is essential that you check that the voltage on

the fuseholder cover below the AC connector on the rear of the chassis is

set correctly before connecting it to AC power.

THIS IS SET FOR

100 V AC TO 120 V

AC OPERATION

To change, pull fuseholder out and rotate 180o, then push in again. Do not insert power cable into unit until voltage has been correctly set. Do not plug power cable into AC power until voltage has been correctly set

WARNING SYMBOLS USED ON THIS EQUIPMENT

This symbol is intended to alert you to the presence of important operating instructions contained in this owner's manual

This symbol is intended to alert you to the presence of uninsulated dangerous voltage within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock.

THIS IS SET FOR

220 V AC TO 240 V

AC OPERATION

PowerPRO Front Panel controls

• Gain and HF energy controls for Channel A and B

• ISC Signal Present and Protect LED indicators. During normal operation the Signal LEDs will light up as soon as any signal runs through the processor. The ISC Protect LEDs will light up on peaks or transients if the system is being used to achieve high SPL. This is normal, and should not be taken as an indication that the system is being over-driven. However, if they are on for the majority of the time, then the Input levels are too high and should be reduced

• Sub Bass enable switch. Switch OUT - Sub Bass not connected; speaker operates full range. Switch IN - Sub Bass operational; speaker operates with a High Pass Filter @ 100 Hz, and 40 to 100 Hz appears at the Sub Output on rear panel to drive a Sub bass cabinet

• Gain control for Sub Bass output, plus Signal and Protect LED indicators

• AC power LED; when lit up indicates that the unit is connected to AC power

PowerPRO

The PowerPRO Interactive System Control Unit is a dual channel processor for the PowerMAX speaker system. It supplies EQ and phase alignment, plus a crossover with Sub Bass output and processing. As well as all this, it also has I.S.C. for speaker protection at absolute sound pressure levels. The Channel B Sub Off switch on the rear panel enables you to use the PowerPRO as a mono system with Sub on Channel A, and use Channel B for full range output, say to a monitor system. Total system flexibility in one rack unit processing! The PowerPRO is placed last in the signal chain before the power amps, usually in the amp rack. Once adjusted to the sound you prefer, it needs no adjusting or calibrating from gig to gig. Just set it and forget it - the PowerPRO does the rest.

About ISC

ISC is short for Interactive System Control, ARX’s innovative speaker protection circuitry. Extra leads run from the Output of the amplifier back into the PowerPRO processor, so that it knows how much power the amplifier is delivering at all times. The PowerPRO is factory calibrated for the PowerMAX series, so it knows the speaker’s exact safe operating area (S.O.A..) As soon as it senses that the amplifier power is reaching danger levels, it triggers the system protection circuits to freeze the level momentarily at the maximum safe level until the power peak has passed. This method of speaker control is virtually foolproof, but it does require that for maximum output you should use an amplifier with a minimum output of 300 watts RMS per channel into 8 ohms. Otherwise an amp of lesser power could distort severely before the PowerPRO protection circuits are activated, running the risk of system failure.

Important

Note that both white leads connect to the OUTPUT of Channel A Amp, Both BLUE leads to the OUTPUT of Channel B Amp, and the Yellow leads to the OUTPUT of the SUB Amp, in parallel with the speaker leads.

Check this wiring very carefully. Don’t get them mixed up, otherwise you will have the output of Channel A controlling the input level of Channel B and vice versa.

The system will sound much better if you get it right!

Introduction

Thank you for choosing this ARX PowerMAX speaker system. We hope you enjoy using it as much as we enjoyed creating it. As with all ARX equipment, it has undergone precise factory calibration, testing and ‘burn in’ before shipping. To ensure continued trouble free use, please familiarise yourself with the contents of this owners manual before using the PowerMAX system.

About the PowerMAX system

The PowerMAX series is a new generation of innovative speaker systems from ARX. Using design techniques borrowed from the award winning ARX concert systems, the PowerMAX brings processor controlled speakers within everyone’s range. Designed to fit your transport as well as your budget, The PowerMAX line features powerful, space saving speaker designs that fit neatly into any vehicle, yet still punch out maximum power. There’s a model to suit every application, including stage monitors, and even a powerful sub for when you have to fill large venues with the PowerMAX sound. All of this is controlled by the PowerPRO speaker processor, a multi channel control unit that provides EQ, crossover (for the PowerMAX Sub) and speaker protection circuitry to keep the PowerMAX sound happening, day after day, night after night

PowerMAX 1

The PowerMAX 1 is a 2 way speaker system featuring an ARX Pro Series 12” (300 mm) bass driver, together with an all new USA manufactured compression driver. The all plywood trapezoidal construction of the PowerMAX 1 provides a strong, rigid cabinet giving breathtaking Highs and powerful Lows from an ultra compact enclosure.

PowerMAX 2

The PowerMAX 2 is also a 2 way speaker system, with an all new ARX Pro Series 15” (380 mm) cast frame bass driver for maximum low end punch. An all new USA manufactured compression driverhandles the high end, coupled to a larger CD fibreglass flare for increased efficiency to match the low end. All ply trapezoidal construction makes the PowerMAX 2 a new dynamic force in compact, powerful sound reinforcement.

PowerMAX 3 and 4

The PowerMAX 3 is a stage monitor version of the PowerMAX 1, featuring the same components assembled in a low profile stage monitor configuration. The PowerMAX 4 is a stage monitor version of the PowerMAX 2, featuring the same components assembled in a medium profile stage monitor configuration. All plywood constuction provides strong, rugged stage monitors with all the power you need to really cut through on stage. Professional XLR connectors are fitted as standard.

PowerMAX SUB

The PowerMAX SUB is a unique Sub Bass cabinet that supplies extra low end punch for the PowerMAX 1 and 2’s when using them in larger venues. Featuring
