QSC Speaker ISIS I-282H


QSC ISIS I-282H dual 8-inch, 2-way, full-range loudspeaker 

The QSC I-282H is a dual 8-inch, 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.
