iSP Trimax 15, trimax 18 Owner's Manual

IMPORTANT SAFETY INSTRUCTIONS!

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 in
use.

 Do not drive the Trimax System 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 Trimax 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 Trimax Active Speaker system. The Trimax
System is a high output three-way active speaker system designed to deliver HI-FI sound
quality for high SPL sound reinforcement applications. The Trimax 15 System 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 Trimax 18 System is
designed with a 600-watt 18-inch woofer, a 300-watt 10-inch midrange driver and a high
performance, 2-inch high frequency compression driver. The Trimax System has three
separate power amplifiers capable of producing upwards of 800 watts of power with the
Trimax 15 and 1000 watts with the Trimax 18. Each amplifier receives its input signal from
an internal 4th 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 Trimax System 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 Trimax

subwoofer cabinet is made of high quality 13 ply Baltic birch plywood with a durable spray
on black finish for long life.

PLACEMENT

The Trimax Subwoofer 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 250 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 airflow over the amplifier heatsink.
