Setting Up Your LX-18A V2 Subwoofer
The B-52 Pro Audio speakers described in this instruction manual are intended for portable used in
which the speakers will be placed directly on the floor, stage or a solid platform. The LX-18A V2
and LX-18 V2 described in this manual should not be suspended or flown. These models are also
not intended for fixed installations outdoors or in high-moisture areas. Moisture can damage the
subwoofer and can cause corrosion of electrical contacts.
Keep speakers out of extended or intense direct sunlight. The subwoofer spider and surround will
prematurely dry out and finished surfaces may fade and be damaged by long-term exposure to
intense ultra-violet light.
B-52 Pro-Audio speakers, especially the LX-18A V2, can produce high-levels of energy. When
placed on slippery surfaces such as polished wood or smooth tiles, the speaker 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 .
Hearing damage, prolonged exposure to excessive SPL
B-52 Pro-Audio speakers, especially the LX-18A V2 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 (ear-plugs) are recommended. Caution should be taken
to avoid extended exposure to SPL in excess of 90 dBA.
Amplifier Module Precautions
Do not attempt to service the LX-18A V2 by yourself. Refer all servicing to a B-52 Pro-Audio
Authorized dealer. Service is required when the LX-18A V2 has had liquid spilled on or inside the
subwoofer, objects have fallen onto the speaker or it has been damaged in any way, the speaker
has been exposed to rain or moisture, does not operate normally or has been dropped.
Keep your LX-18A V2 amplifier away from sources of heat such as a radiator or intense sunlight.
Do not cover your LX-18A V2 amplifier with material that may retain heat, such as a blanket or curtain. Be certain that the vents on the panel of the amplifier are clear of all obstructions during operation.
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 LX-18A V2(S) near a pool or other standing water. Do not bypass or defeat the grounding or polarization means used on the LX-18A V2 amplifier. 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 LX-18A V2 amplifier should be cleaned only with a dry cloth.
