ETI Sound Systems, INC LX-18 - Manual (Page 2)

Use shielded speaker cable with stranded conductors. Do not use
audio cable that is insufficiently rated for the amplifier’s maximum
output amperage. 16-gauge or larger wire is recommended. Longer
cable run distances require larger cable. Use of inappropriate cable
can create a fire hazard!
CABLING CAUTION
Thank you for choosing the B-52 LX-18V2 subwoofer. For best performance
and years of trouble-free operation, please read this Owner’s Manual before
use. Please follow and keep these instructions. Please heed all warnings.
1) Location of Subwoofer:
a. Avoid areas with high temperature (i.e. near heater).
b. Keep speakers out of extended or direct sunlight.
c. The LX-18V2 is intended for portable use in which the speaker should be
placed on the floor, stage or a solid platform. Do not place on
unstable or non-level surfaces.
d. The LX-18V2 can produce high-energy levels. 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.
e. If a full-range cabinet is placed on top of the LX-18V2, it should be
secured to the subwoofer to prevent the speaker from falling off.
2) Hearing damage, prolonged exposure to excessive SPL:
B-52 Pro-Audio speakers, especially the LX-18V2s, are capable of pro-
ducing sound pressure levels (SPL) sufficient to cause permanent
hearing damage to performers, production crews or people in the
audience! Adequate hearing protection devices are recommended.
Caution should be taken to avoid extended exposure to SPL in
excess of 90 dBA or at a level that causes discomfort.
3) Do Not Suspend:
The LX-18V2 is not intended for suspension or hanging. Under NO
circumstance should you attempt to suspend or hang this subwoofer.
PRECAUTIONS:
1) Your system must be turned completely OFF before connecting or
disconnecting the LX-18V2. Connecting or disconnecting the LX-18V2
while the sound system in ON may damage the subwoofer and the audio
components in your sound system.
2) Make sure the gain or level control(s) on the amplifier(s) is turned all the
way down when turning the system on or off!
3) Disconnect the LX-18 prior to moving the sound system or the subwoofer.
POWER UP / DOWN YOUR SYSTEM:
MAXIMUM BASS
OUTPUT
The LX-18V2 should be
arrayed in groups of two or
four and placed adjacent
to structural surfaces. This
will act to extend the horn
wall of the LX-18V2 and
will enhance low-frequency
output. Placing
subwoofers adjacent to
each other results in a
coupling effect, which will
increase the total bass out-
put of the system.
