[. . . ] 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.
