The QSC K Series is quite simply The New Standard in lightweight powered loudspeaker systems. Under the direction of Pat Quilter, QSC's team of amplifier engineers have created a new standard in Class D power modules unparalleled in the industry. Next, breaking from the traditional loudspeaker paradigm, every model is fitted with the identical 1.75" HF device (full-range models) and woofers of the same high quality for unparalleled performance, regardless of speaker size.

Combo XLR and 1/4" TRS inputs accept both Mic and Line input while a set of RCA phono inputs (except KSub) allow additional connectivity to portable MP3 players, CD players and line-level mixers. Up to three audio sources can be mixed internally and summed to a balanced output for "daisy-chaining" of multiple units. Separate direct outputs are also provided on each channel for additional output flexibility.

Mounting brackets available, for install please call us to make arrangements.
