Matrix Amplification XT2004EQ, XT6004EQ, XT4004EQ User Manual

XT SERIES USER MANUAL 1

Thank You

Congratulations on the purchase of your new
Matrix Professional Power Amplifier.
Matrix amplifiers are the result of many
decades of experience in the design of
exceptionally robust and reliable amplifiers.
They are designed to breathe life into your
sound, by controlling your speakers with
exacting authority through the
uncompromising delivery of clean,
undistorted power, from a package which is
smaller and lighter than you might expect
for the performance it delivers.

This manual will help you to get the most
from your amplifier. For maximum benefit, it
is recommended that all instructions and
warnings are carefully read. Also be sure to
read the notices regarding correct wiring of
output connectors as this impacts the
operation of the amplifier.

For warranty service, please retain your
receipt and all packaging that comes with
the amplifier, as it has been specifically
designed to transport the amplifier safely.

Unpacking

Please unpack and inspect your new
amplifier for any damage that may have
occurred during transit. If damage is found,
notify the carrier immediately.

Note: A suitable mains lead is provided and
can be found packaged with the amplifier.

PLEASE RETAIN ALL FACTORY PACKAGING
FOR ANY FUTURE POSTAL TRANSIT.

1. Features and Innovations

All our amplifiers have been designed to give the best possible performance for their
intended application and are based on our own uncompromising, time proven MOSFET designs.
These take advantage of components which will stand the test of time and give the best possible
performance in a small, exceptionally light weight package.

We only have the desire to provide our users with the best possible solutions and continue to
look for ways to improve upon them.

Amplifier features:

• Class AB, MOSFET amplifier topology.

.

• An unprecedentedly powerful and stable Switch Mode Power Supply.

Designed without compromise, to exceed the performance of the previous linear supply

models; whilst offering a weight advantage rarely seen even in other SMPS amplifiers.

.

• Soft Start Circuit.

The power supply is designed not to draw excessive current on startup - Prevents the 'thump'

, as occasionally seen with other equipment, from tripping fuses and breakers.

.

• Protection against Short Circuit and Overheating.

.

• Speaker Protection relay with delay to inhibit switch on thump.

The speakers are disconnected during power up/down.

• Fully balanced XLR Inputs.

• .

• Stereo, Mono and Bridged (Mono) Modes selectable via rear panel switches.

Mode of operation indicated on front panel LED status display.

.

• In Mono Mode, only input A is used to feed channel pair A and B (also applies

likewise to input C of pair C and D). Independent control of each channel's output

level remains functional.

.

• Temperature regulated, High Speed Fan Cooling.

A new high speed fan is utilised to ensure maximum reliability by allowing for far greater

cooling latitude (The amplifier vents hot air through rear connector panel).

.

• Active Analog Crossover.

A rear panel accessible crossover is provided to facilitate the use of the amplifier directly with

subwoofer and speaker systems, that normally require a separate active/passive crossover to

function as intended.

.

• 4 Channel Model.

4 channels of amplification provided in a case size which would normally only offer 2

channels; Optimising the use of available racking space in complex amplifier instillations.

Operating Environment:

● The amplifier is designed for use in environments which protect it from rain, unusually

high air humidity and temperature.

● When mounting inside, ensure that the amplifier is securely bolted into a rack using all

available fixing points where possible. Otherwise place on a surface where it cannot be
easily displaced, Potentially causing damage/injury. Ensure That the location will not
expose the amplifier to spillage of liquids/drinks, sprays/vapours or high humidity. Ensure
the amplifier is installed in a place which is not subject to abnormally high temperatures
and maintain sufficient ventilation to prevent overheating.

● For temporary use outside, apply similar caution; however be extra sure to ensure

placement accounts for changing weather conditions and that extreme wind/rain/heat will
not find its way to equipment.

● When taking any equipment from a cold environment (unheated storage, vehicles, etc),

into a warm one, allow the equipment time to acclimatise to the ambient temperature, as
condensation is likely to form in the amplifier, potentially causing it to malfunction if put
into service too soon.

Note: Our policy of continuous improvement may lead to the above specifications being

exceeded prior to documentation being updated.
