1 XT SERIES USER MANUAL CONTENTS: Page 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.
XT SERIES USER MANUAL 2 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.

5 XT SERIES USER MANUAL . 3. Interface Elements, Front Panel. . (1) Power Switch . This switch controls the power supply to the amplifier. There is a short delay on power-up, this is to avoid switch-on "thump" which could damage the loudspeakers. . (2) Gain Controls . The level of each Channel is individually adjusted by these controls. Rotating these controls fully clockwise, results in no attenuation to the incoming audio signals. . (3) Indicator Section, Status: . a.
XT SERIES USER MANUAL 6 3. Interface Elements, Rear Panel. . (5) Cooling Fan Outlet . Hot air exits here. M ake sure all rear (and front) ventilation paths are free from obstruction and air flows freely, otherwise the amplifier will trip into thermal protect mode prematurely and in some extreme circumstances damage may occur. (6) Output Connectors . The Output sockets are Neutrik Speakons and accept a Neutrik NL4FC plug.
7 XT SERIES USER MANUAL (7) Input Signal Sockets . Signal input connections are provided via Female XLR sockets. Industry standard Balanced XLR format, which helps ensure interference and noise free connections between equipment. Ready-made, sensibly priced, quality interconnection leads suitable for use with the amplifier should be easy to source. However, with sufficient skill, it is possible to make/modify leads for the task. Proceed to Chapter 5. - “Cables, Making your own”. .
XT SERIES USER MANUAL 8 4. Recommended Usage: To ensure your speaker and amplifier system functions optimally, it is advised to read through everything covered in this manual. Safety precautions and appropriate usage recommendations for specific connections and features are noted in the previous section. . 4.1 Matching Speakers to the amplifier: .
9 XT SERIES USER MANUAL 4.2 Using Bridge Mode: Only use this mode of amplifier operation where the power available from one amplifier output channel alone, is not sufficient for the connected speaker system. This mode works by using two amplifier output stages together in series, using specialised internal amplifier circuitry. The following points about this mode of operation should be considered with care.

Speakon Connectors, 4 Pin: Cable Maker Table: Cable Connections: Cable Type: + and - + and - Single Channel, 2 core lead. 1 to 1 - Dual Channel, 4 core lead. 1 to 1 2 to 2 Use in Mono / Stereo modes. For both channels into one cable. Outputs A and B - 4 ohms minimum load Bridged (mono) mode.
XT SERIES USER MANUAL 12 The previous table is a rough guide for recommended cable gauges. It is important to use sufficiently heavy duty cables (try to use at least 2.5mm 2 ) and plan the use and instillation of sound equipment such that the speaker cables in particular are kept short where possible (under 6m/20ft should provide enough flexibility to cover most applications). . Speaker cables are usually made with copper to act as the conductor carrying power.
13 XT SERIES USER MANUAL . 6. TROUBLE SHOOTING. . (1) ALWAYS: ● Ensure the amplifier has no less than 4 Ohms worth of loading across each channel for Stereo/Mono modes. ● Ensure Bridge Mode (if used) is wired correctly (see chapters 4.2 and 5.2) and is loaded with no less than 8 Ohms. ● Wiring is safe and correct. . (2) NORMAL ARTIFACTS: ● ● When heavily driven, the amplifier itself may make a noticeable hissing sound in relation to the supplied signal.
