ISP Technologies Tripower 900 User Manual

PRECAUTIONS!

Please read this very carefully before operating this unit

• Read ALL instructions carefully before using this unit.

• Do not operate 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 service personnel.

• Never remove or defeat the ground connection on the power cord of this
unit.

• Care should be taken to avoid spilling any foreign objects or liquid into this
unit.

• This active speaker system has three internal power amplifiers and an
external heatsink located on the back of the speaker for cooling of the
internal amplifiers. Care should be taken to avoid placing this active
speaker in a location where the external heatsink does not allow proper
cooling of the internal amplifiers. 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 is
use.

• Do not drive the Tripower 900 into excessive heavy distortion for an
extended period of time to avoid premature speaker failure.

• Failure to follow these instructions may void the warranty.

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
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.

PLACEMENT

The Tripower 900 is designed to sit on the floor or stage. Do not position or mount the
cabinet where it can tip over and fall on someone. Do not attempt to mount the cabinet on
speaker stands. Do not attempt to ‘fly’ (suspend by cables, chains, ropes, etc.) the cabinet.
It was not designed for flying. Position it only on a flat, stable surface where it is not in
danger of tipping over.

Also note that the placement of the cabinet relative to floors and walls will affect the low

frequency response (below about 500 Hz.). Placing it closer to the floor and walls will
reinforce the low frequency response. The closer it is, the higher in frequency this
reinforcement will go. Also make sure that adequate space (at least 6 inches) is left behind
the cabinet for air flow over the amplifier heatsink.

REAR PANEL DESCRIPTION

1. POWER SWITCH-This switch provides power to the Tri-Power power amp section. This
switch is a three-position switch where center is OFF and the outer positions are ON.

2. POWER INLET MODULE-This module provides a connection for the power cord and also
houses the mains fuse. (See Fuse Replacement Section)

3. INPUT GAIN- This control determines the overall input level of the signal to the power
amp section of the Tri-Power cabinet. Adjusting this level will not affect the level of the
signal passing through to output connectors.
