1) Read these instructions.
2) Follow all instructions
3) Keep these instructions
4) Heed all warnings
5)
Do not use the MATRIX-600 near water. Be
extra cautious when moving the system
during rain or while transporting the system
over wet surfaces as water might splash on to
the amplifier. To reduce the risk of fire or
electric shock, do not expose the system to
rain or moisture.
6) Clean only with dry cloth.
7)
Do not block any ventilation openings. Use
in accordance with manufacturer’s instructions.
8) Do not use near heat sources such as
radiators, stoves or other devices that may
produce heat.
9) Do not defeat the safety purpose of the
polarization or grounding-type plug. A
polarized plug has two blades with one wider
than the other. A grounding-type plug has two
blades and a third grounding prong. The wide
blade or the third prong is provided for your
safety. If the provided plug does not fit your
outlet, consult an electrician for replacement
of the obsolete outlet.
10)
Protect the power cord from being walked on
or pinched, particularly at the plug and at the
point where it exits the MATRIX-600 amplifier.
11) Only use attachments / accessories
recommended by B-52 Pro-Audio.
12) Use caution when transporting the system to
avoid injury from tip-over.
13) Unplug the MATRIX-600 during lightning
storms or when not in use.
14) Refer all servicing to qualified personnel.
Servicing is required when the MATRIX-600
has been damaged in any way, such as the
power-cord or plug is damaged, liquid has
been spilled into the cabinets, the unit has
been exposed to moisture or rain, does not
operate normally, or has been dropped.
15) The MATRIX-600 is not intended for outdoor
fixed installations or in high moisture areas.
Moisture can damage the speakers and can
cause corrosion of electrical contacts. Keep
speakers out of extended or intense direct
sunlight. The speaker surfaces may fade and
be damaged by long-term exposure to intense
ultra-violent light.
IMPORTANT INFORMATION
Hearing damage, prolonged exposure to excessive SPL
B-52 Pro-Audio speakers, including the MATRIX-600, 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 as ear-plugs are recommended.
Caution should be taken to avoid extended exposures to SPL levels in excess of 85dB.
Amplifier Module Precautions
Do not attempt to service the MATRIX-600 by yourself. Refer all servicing to a B-52 Pro-Audio
Authorized dealer. Service is required when the MATRIX-600 amplifier has been exposed
to liquids or suffered damage. Do not operate the unit if liquid has spilled into the amplifier.
Immediately remove the power cord from AC mains power if such an event should occur.
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-600 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-600 amplifier should be cleaned only with a dry cloth.
Cautions
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 in extreme cases, death.
2) B-52 Pro-Audio speakers, especially the MATRIX-600, can produce high-levels of
energy. When placed on slippery surfaces such as polished wood or smooth tiles, the
loudspeakers may move because of intense bass output. Precautions should be
taken to ensure the speakers do not fall off of a stage or raised surface.
3) Do not block the air intake on the rear panel and air exit slots on the top (below the
wooden handle). The Matrix-600 has a high power amplifier, which dissipates heat
and needs unobstructed air circulation to cool down its heatsink.
4) Please turn the volume down prior to turning the system ON to prevent possible
damage to the speakers.
5) If you are using an optional active subwoofer with the MATRIX-600, make sure all of
the cables from the subwoofer are connected to the MATRIX-600, the subwoofer’s
volume control(s) and the volume control of the MATRIX-600 are turned all the way
down, before either unit is powered ON.
6) After connecting your source(s) to the MATRIX-600, make sure your MATRIX-600 and
the signal sources have their volume controls turned all the way down before powering
ON the MATRIX-600 to avoid turn ON thumps that could damage your speakers.
7) The MATRIX-600 should always be switched ON last, after you switch ON all
connected devices and in turn switched OFF first when powering down your system.
CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
HEED ALL WARNINGS
WARNING: To reduce the risk or fire
or electrical shock do not expose this
equipment to rain or moisture.
CAUTION: Connect the power cable only after you have absolutely made
sure that the local mains voltage matches the voltage specified on the
device. If you connect to the wrong voltage, you may destroy the
electronic components of the MATRIX-600 system.
See page 4 for a complete description of factory-default voltage settings.
