ISP Technologies Tripower 900 - Manual (Page 2)

Caution: Exposure to extremely high noise levels can
cause permanent hearing loss.
The Tripower 900 speaker system is capable of producing in excess of 129db 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 Tripower 900 active speaker system. The
Tripower 900 is a high output three-way active speaker system designed to deliver HI-FI
sound quality for high SPL sound reinforcement applications. The Tripower 900 is
designed with a 400 watt 15 inch woofer, a 300 watt 10 inch midrange driver and a high
performance, 2 inch high frequency compression driver. The Tripower 900 has three
separate power amplifiers capable of producing upwards of 900 watts of power. Each
amplifier receives its input signal from an internal 4
th order crossover network specifically
designed to provide optimized phase and frequency response at each crossover point.
The internal amplifiers are 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 Tripower 900 offers both ¼ inch RTS and XLR balanced inputs as well as, ¼ inch RTS
and XLR outputs for connecting multiple speakers. A sensitivity adjustment knob allows
you to adapt the speaker for a wide range of common signal levels. The Tripower cabinet
is made of high quality 13 ply Baltic birch plywood with a durable spray on black finish for
long life.
