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.
1. INPUT GAIN- This control determines the overall input level of the
signal to the power amp section of the TRIMAX cabinet. Adjusting
this level will not affect the level of the signal passing through to the
output connectors.
2. BALANCED ¼” PHONE INPUT- This jack provides an input for
balanced or unbalanced line level signal source.
3. BALANCED XLR INPUT- This female XLR connector provides an
input for balanced line level source.
4. BALANCED ¼” INPUT- This ¼’ phone provides a balanced loop
through for connecting to additional powered cabinets.
5. BALANCED XLR OUTPUT- This XLR male provides a balanced
loop through for connecting to additional powered cabinets.
6. SUB LEVEL- This control determines the overall input level of the
signal to the power amp section of the subwoofer of the TRIMAX sub
cabinet. This control will allow you to fine-tune the level of the sub
section with respect to the top boxes.
7. TOP BOX CONNECTOR- This Speakon connector provides an
output for the TRIMAX 10 top box with the configuration switch in the
biamped position or with use of another manufacturer’s top box with
the switch in the full range position. NOTE: See block diagram for pin
configuration.
8. EXTERNAL TOP BOX CONNECTOR- This Speakon connector
provides an additional output for a second TRIMAX 10 top box or full
range cabinet depending on the position of the configuration switch.
This connector is a parallel connection to the other Speakon
connector. NOTE: When using more than one top box of another
manufacturer with the TRIMAX sub, each cabinet should not be less
than 8 ohms.
9. POWER SWITCH- This switch provides power to the TRIMAX
system. Make sure that the input sensitivity control and sub level
control is set to minimum upon power up.
10. POWER INLET MODULE- This module provides a connection for
the power cord and houses the mains fuse. (See Fuse
Replacement Section)
REAR PANEL DESCRIPTION
FUSE REPLACEMENT
1. Use a small screwdriver as shown to slide the fuse cover
out from the power inlet module. The fuse can be found
inside the fuse cover module after it is pulled out.
NOTE: A SMALL COMPARTMENT IS ALSO PROVIDED WITHIN THE FUSE COVER
MODULE FOR STORING A SPARE FUSE.
2. After replacing the fuse with another of identical
specifications, push the fuse cover module fully back into
place, ensuring that the fuse has snapped onto the fuse
holder inside the power inlet module.

SYSTEM DIAGRAM DESCRIPTION
SYSTEM DIAGRAM DESCRIPTION
The ISP TRIMAX Series has balanced XLR and inputs and outputs configured to AES standards
(Audio Engineering Society). These connections are connected in a loop through configuration
from the inputs to the full range outputs and will accept a balanced line-level input. The standard
phase configuration is that pin 2 is (+), pin 3 is (-), and pin 1 is shielded ground on the XLR.
THERMAL CONDITIONS
The ISP Trimax 15 System is capable of producing upwards of 700 watts RMS when driving one
top box and 800 watts when driving two top boxes off the same sub cabinet. The TRIMAX 18
system is capable of producing over 1000 watts when driving two TRIMAX 10 top boxes. This
generates heat that must be dissipated in order to maintain reliability and insure the amplifier
components stay within their operating temperature specs. To accomplish this, the amplifier is
mounted onto a heatsink that is exposed on the rear of the cabinet. Airflow is forced through the
fins via the air pressure from the speaker. It is recommended that the fins have at least 6 inches
of clearance from any obstruction to allow proper ventilation to occur.
In addition, the amplifiers are thermally protected internally via a thermal switch that will
attenuate the signal 40db when the temperature exceeds a certain point. When the temperature
drops below a certain point, full signal will be restored. Tests have shown under extreme
conditions that cycling will occur. (40 sec. ON, 20 sec. OFF) Under extreme conditions, such as
when ambient temperatures are too high (hot rooms, extreme outdoor temperatures) it is
recommended to use a fan on the fins to reduce the cycling affects.
