Description

Details

The QSC K12 12 inch 2 Way Loudspeaker is quite simply The New Standard in lightweight powered loudspeaker systems. For starters, each of the four models features an all new, Pat Quilter designed 1000 watt continuous QSC Class D power module. 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.

Extensive DSP processing is employed throughout, providing levels of sonic clarity and total output that defy the system’s size and weight. Premium-grade materials, advanced construction processes and multiple mounting and suspension options allow for a wide range of live and installed applications.

The combo XLR and 1/4" TRS inputs accept both Mic and Line Level 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. The on-board switches provide preset EQ settings. The HF setting (full-range models) can be set to VOCAL BOOST for additional presence in the critical mid-frequency area or FLAT for accurate reproduction of the incoming signal.
