SECTION 2 :
BEFORE YOU BEGIN
The VP Series loudspeakers covered by this manual are not intended for fixed installation in outdoor
or high moisture environments. Moisture can damage the speaker cone and surround and cause
corrosion of electrical contacts and metal parts. Avoid exposing the speakers to direct moisture. Keep
loudspeakers out of extended or intense direct sunlight. The driver suspension will prematurely dry out
and finished surfaces may be degraded by long-term exposure to intense ultra-violet (UV) light.
The VP Series loudspeakers can generate considerable energy. When placed on a slippery surface such
as polished wood or linoleum, the speaker may move due to its acoustical energy output. Precautions
should be taken to assure that the speaker does not fall off a stage or table on which it is placed.
Stand mounting safety precautions
Some VP Series models can be used with an optional stand mount accessory allowing mounting
on tripod stands or on a pole over subwoofers. When using stands or poles, be sure to observe the
following precautions:

Check the stand or pole specification to be certain the device is designed to support the
weight of the speaker. Observe all safety precautions specified by the manufacturer.

Always verify that the stand (or subwoofer / pole) is placed on a flat, level, and stable surface
and be sure to fully extend the legs of tripod type stands. Position the stand so that the legs
do not present a trip hazard.

Route cables so that performers, production crew, and audience will not trip over them and
pull the speaker over.

Inspect the stand (or pole and associated hardware) before each use and do not use equipment
with worn, damaged, or missing parts.

Do not attempt to place more than one VP Series loudspeaker on a stand or pole.

Always be cautious in windy, outdoor conditions. It may be necessary to place additional
weight (i.e. sandbags) on the base of the stand to improve stability. Avoid attaching banners or
similar items to any part of a speaker system. Such attachments could act as a sail and topple
the system.

Unless you are confident that you can handle the weight of the speaker, ask another person
to help you get it onto the tripod stand or pole.
Hearing damage, prolonged exposure to excessive SPL
VP Series loudspeakers are easily capable of generating sound pressure levels (SPL) sufficient to
cause permanent hearing damage to performers, production crew and audience members. Caution
should be taken to avoid prolonged exposure to SPL in excess of 90 dB.
