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 4
th
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.
