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.

GETTING TO KNOW YOUR
LX-18A V2 ACTIVE 18” SUBWOOFER
PANEL CONTROLS
11) Level Control: Sets the volume of the subwoofer
12) Phase Switch: Sets the polarity of the LX-18A V2.
13) Power Indicator: The Power indicator lights when the LX-18A V2 amplifier
has been turned on and has power.
14) Protection: Red LED turns on when distortion is audible in the
amplifier output. This indicates that you should turn the amplifier down.
15) Right & Left Inputs: These inputs are summed and sent to amplifier’s
Low Pass filter (120 Hz and below).
16) Right & Left Full-Range Outputs: Send stereo full-range signal
allowing daisy chaining of additional subwoofers. You do not need to
y-cable out of your mixer or audio device to get an additional full-range signal.
17) Right & Left High-Pass Outputs: Send stereo high-pass signal (120 Hz and
above) directly to active, full-range speakers or through a rack-mount amplifier
to passive speakers.
18) External Speaker On/Off Switch: Turns Speakon NL-4 connector (and external
subwoofer) on and off. When only using the LX-18A V2, turn this switch off.
When an external, non-powered subwoofer (LX-18 V2) is connected, turn this
switch on. NEVER turn switch on or off while amplifier is at full volume.
19) External Speaker Output: The Speakon NL-4 connector connects the amplifier
to an external, non-powered subwoofer (LX-18 V2). Either pins 1+ and 2+ can
be used as the positive connection. Either pins 1- or 2- can be used as the
Negative Connection. External subwoofer must be 8 Ohms
10) ON/OFF Switch: Turns the LX-18A V2 amplifier on or off. The LX-18A V2
will only turn on when the amplifier detects an audio signal.
11) Fuse Holder: Houses a fast-resetting 12 amp fuse.
12) Power Cord Connector: For attachment of the included power cord.
