DP Series systems 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.

® DP Series Fullsize Powered Line Array loudspeakers can be suspended with available
array frames (P/N VT889-AF, VT889-SF) or they can be ground-stacked. These systems can
generate considerable energy. When placed on a slippery surface such as polished wood or
linoleum, a single 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 scaffold platform on which it is placed.
While it is unlikely that a ground-stacked array will move when properly attached to its array frame,
precautions should be taken to assure that the array assembly cannot fall from any surface on
which it is placed. Hearing damage, prolonged exposure to excessive SPL V

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.
