Hearing damage, prolonged exposure to excessive SPL
B-52 Pro-Audio speakers, including the MATRIX 2000, are capable of producing sound pressure levels (SPL) sufficient to cause
permanent hearing damage to performers, production crews or people in the audience. Hearing protection devices such earplugs are
highly recommended. Caution should be taken to avoid extended SPL.
Amplifier Module Precautions
Do not attempt to service the MATRIX 2000 by yourself. Refer all servicing to a B-52 Professional Authorized Service Center or
directly to B-52. Service is required when the MATRIX 2000 has had liquid spilled on or inside the subwoofer or speakers, has been
damaged in any way, the speaker has been exposed to rain or moisture, does not operate normally or has been dropped.
WARNING – Shock Hazard:
To reduce the risk of fire or electrical shock, do not expose this unit to rain or moisture. Do not operate your MATRIX 2000 near a pool
or other standing water. Make sure all blades on the polarized power plug are fully inserted into the power source. Ensure the power
cord is not stretched, pinched or otherwise abused. Ensure the power cord is routed to avoid foot traffic. Your MATRIX 2000 amplifier
should be cleaned only with a dry cloth.
The MATRIX 2000 Active Speaker System
CAUTION:
1) Do not hang the speakers by yourself. You must have a professional and licensed contractor hang the speakers. Speakers not
properly flown/hung can fall causing injury or extreme cases, death.
2) B-52 Professional speakers, especially the MATRIX 2000, can produce high-levels of energy. When placed on slippery surfaces
such as polished wood or smooth tiles, the subwoofer may move because of its intense bass output. Precautions should be
taken to ensure the subwoofer does not fall off a stage or raised surface.
3) Turn the gain knobs all the way down before turning the system ON or OFF.
4) Make sure the active subwoofer is connected to the two-way speakers before powering the system up.
5) Make sure your mixer and all other signal sources are turned ON before connecting the MATRIX 2000.
6) The MATRIX 2000 should always be switched ON last, after you switch ON all connected devices.
Congratulations on your purchase of this B-52 Professional MATRIX 2000.
The MATRIX 2000 is a complete sound reinforcement solution consisting of two 12” two-way speakers and an 18” subwoofer,
equipped with a built-in three-channel amplifier. The three-channel amplifier houses all the electronics required to run the system.
The electronic circuitry was fine tuned to match all of the components for the best possible sound. The MATRIX 2000 is designed for
easy operation, as you do not need to worry about tweaking frequencies and finessing levels. All you have to do is set up the
system’s components, connect the XLR right and left signal cables, speaker cables and power cord and you’re ready to go!
18” SUBWOOFER:
The 18” subwoofer enclosure is divided into two separate compartments. The front chamber serves as the cabinet for the
cast-framed, 4” voice coil, 18” subwoofer. The rear chamber houses all of the system’s electronic circuitry, which includes the
amplification for all three components, power supply, compressor and preamps. The 18” subwoofer has a power handling
capability of 600 watts and a nominal impedance of 8 ohms.
12” TWO-WAY SPEAKERS:
Each 12” two-way speaker is loaded with a B-52 custom designed 12” loudspeaker and a 1” titanium diaphragm compression
driver, mounted to a 90

constant directivity horn. The speakers are designed to be pole mounted, can sit as stage
monitors and have built-in (3/8” – 16 TPI) flying hardware for permanent installations. The front panel of both two-way speakers
are convex so as to fit perfectly on to the subwoofer’s front grille for easy transport. Each two-way speaker has the power
handling capability of 300 watts and a nominal impedance of 4 ohms.
Using the Speakon-style Connector:
To establish a connection, plug the connector and rotate it clockwise until it engages. Before you unplug it, you will first need to
disengage the safety catch. To accomplish this, pull the catch towards yourself.
Connections: Pin 1+ = +, Pin 1- = -, Pin 2+ and Pin 2- are not connected.
CAUTION: The system’s components are matched for the best possible sound quality and may only be operated in the specified
configuration provided in this manual.
DO NOT CONNECT ADDITIONAL SATELLITE SPEAKERS TO THE AMPLIFIER. Connecting
additional speakers may hinder the sound quality and can damage the power amplifier.
TRANPORTING THE SYSTEM:
Place the subwoofer on to its casters and place the included cover over the subwoofer. Next, place the included covers over the
two 12” two-way speakers and close the zippers. It is recommended that you transport the subwoofer and satellites separately.
You may transport all the components at the same time by placing the satellite speakers on to the subwoofer’s front panel
facing down. Secure the satellite speakers to the subwoofer with the included locking strap by fastening it to the bar handles on
the side of the subwoofer cabinet.
Caution: Use caution when transporting the system to avoid injury or tip over. Do not move the system in such a manner or at
such a speed that you would run the risk of the satellites falling off the subwoofer box.
