IMPORTANT SAFTEY INSTRUCTIONS

Please read the following very carefully before operating this unit

 Read ALL instructions carefully before using this unit. Keep these instructions for future reference. Heed all warnings and f ollow

all instructions.

 Do not use this unit near water, in the rain, or where there is moisture. If this warning is ignored a serious electrical shock or

death may occur.

 Do not attempt to service this unit. No user serviceable parts inside. Refer servicing to qualified, ISP approved personnel.

Servicing is required when the unit is damaged in any way, such as power supply cord or plug is damaged, liquid has been
spilled or objects have fallen into the unit, the unit has been exposed to rain or moisture, does not operate normally, or has
been dropped.

 Do not block any ventilation openings on the unit. Do not install near heat sources such as radiators, heat registers, stoves, or

other apparatus that produces heat.

 Do not defeat the grounding pin on the power plug. A grounding type plug has two blades and a third grounding prong. If the

grounded plug does not fit in your outlet, please consult an electrician for replacement of the outlet, which may be obsolete.

 Care should be taken to avoid any foreign objects or liquid into this unit. Avoid exposure of this equipment to dripping or

splashing and ensure that no objects filled with liquid, such as vases, are placed on the equipment.

 Only use accessories or attachments that are specified by the manufacturer.
 Use only with the caster attachment, stand, connecting bracket, or table specified by the manufacturer, or sold as an accessory

with the unit. When a castor attachment is used, use caution when moving the cart/apparatus combination to avoid injury from
tipping over.

 To completely disconnect this unit from the AC mains, disconnect the power supply cord plug from the AC receptacle.
 This active speaker system has internal power amplifier(s) and a heatsink located internally with cooling ports on the back of

the unit for airflow over the heatsink. Care should be taken to avoid placing this active speaker in a location where the airflow
over the heatsink is impeded and proper cooling of the internal amplifiers is not provided. Avoid placing this system close to
other heat sources. The external heatsink may reach high temperatures under normal use. Do not block the external heatsink
with any other object. Make certain there is proper ventilation for the external heatsink when in use.

 Do not drive the unit into excessive heavy distortionfor an extended period of time to avoid premature speaker failure.
 Failure to follow these instructions may void the warranty.

THIS UNIT CONTAINS POTENTALLY LETHAL VOLTAGES. TO PREVENT ELECTRIC SHOCK

OR HAZED, DO NOT REMOVE THE POWER AMPLIFIER MODULE, INPUT PANEL OR AC

INPUT PANEL. NO UER SERVICABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED

ISP TECHNOLOGIES SERVICE PERSONNELL.

The lightning bolt triangle is used to alert the user to the risk of electric shock.

Caution: Exposure to extremely high noise levels can
cause permanent hearing loss.

The XMAX speaker system is capable of producing in excess of 130db SPL at 1 meter.
Continued exposure to noise levels in excess of 90db may cause permanent hearing loss.
Below is a chart of the OSHA (Occupational Safety & Health Administration) regulations for
Occupational Noise Exposure. Please note: OSHA requires hearing protection for any work
environment when the sound levels exceed those shown in Table G-16 when measured on the
A scale of a standard sound level meter at slow response.

INTRODUCTION

Thank you for purchasing ISP Technologies XMAX active subwoofer system. The XMAX is a
high output active subwoofer system for high SPL sound reinforcement applications. The
XMAX was designed with a 1000 watt 18 inch woofer. The XMAX incorporates a High
Current D-CAT power amplifier system capable of producing upwards of 600 watts RMS as
a stand-alone system. The XMAX can deliver over 1000 watts RMS power. The amplifier
receives its input signal from an internal 4th order crossover network specifically designed to
provide optimized phase and frequency response for a composite system. The internal
amplifier is based on ISP Technologies patent pending D-CAT (Dynamic Current Amplifier
Technology) amplifier technology. The D-CAT technology is capable of delivering extremely
high output current providing an improvement in transient response, output current and a
noticeable improvement in PUNCH. The D-CAT amplifier technology utilizes a monolithic
power amplifier driver that reduces parts count and greatly improves reliability. The D-CAT
amplifiers provide improved reliability by including short circuit and over temperature
protection.

The XMAX offers XLR balanced inputs and XLR balanced full range and High Pass outputs
allowing connections for multiple speakers in a system. A sensitivity adjustment knob allows
you to adapt the XMAX speaker for a wide range of common signal levels. The XMAX
subwoofer cabinet is made of high quality 13 ply Baltic birch plywood with a durable spray on
black finish for long life.
