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.
The VRX 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 speakers 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 VRX Series speakers 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.
