The QSC I-82H is an 8", 2-way, full-range loudspeaker
with contemporary styling that integrates into
multiple environments. With the ability to be pole
and mic stand mounted, truss mounted, or used
as a floor monitor/stage fill, these injection molded
speakers are an excellent choice for musicians,
mobile entertainers, and others needing a high-
quality, lightweight SR package that sounds great, is
visually unobtrusive, and with its built-in handles, is
easy to transport.
The I-82H enclosure incorporates an 8" weatherproof,
LF transducer with a heavy-duty double roll cloth
surround 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-82H provides two parallel
Speakon
® connectors.
An ideal solution for a variety of mobile SR
applications, the I-82H includes a pole cup bracket
for pole mount applications as well as a 5/8"-
27 mic stand adapter that fits most mic and
boom stand hardware. With the addition of QSC’s,
optional I-YM8 Yoke Mount/Floor Monitor Kit (which
contains a bracket with swivel extension feet), the
I-82H can be horizontally pole mounted for pan
and tilt focusing or used as a floor monitor. For truss
mounting, the I-YM8 accepts most industry standard
truss clamps.
