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.
