The QSC I-282H is a dual 8",
2-way, full range loudspeaker
with contemporary styling that
easily integrates into multiple
environments. Pole mounted,
truss mounted, or used as a floor
monitor/stage fill, these injection
molded speakers are an excellent
choice for musicians, mobile
entertainers, and anyone else
needing a high-quality, lightweight
SR package that sounds superb,
is visually unobtrusive, and with
its built-in handles, is easy to
transport.
The I-282H enclosure incorporates
two 8" weather resistant, LF
transducers with heavy-duty
double roll cloth surrounds and
a 1" exit HF compression driver.
The HF driver is coupled with
QSC's unique Advanced Directivity
Rotatable Waveguide—enabling the
loudspeaker to deliver accurately
focused sound, regardless of its
orientation. For quick and secure
input setup, the I-282H provides
two parallel Speakon connectors.
An ideal solution for a variety of
mobile SR applications, the I-282H
includes a pole cup for pole
mounting with either 1 1/2" or 1
3/8" diameters. Or by using the
included yoke mount with swivel
extension feet, the I282-H can be
vertically or horizontally mounted
for pan and tilt focusing or used as
a floor monitor. For truss mounting,
the yoke accepts most industry
standard truss clamps.
