Audio engineers and rental houses looking for a portable, versatile, and simple to use PA will be thrilled with the 8" QSC K8.2, a 2000W powered PA speaker that functions as a main PA in a wide variety of positions and with a pair, can cover an audience up to 250. The onboard DSP processing, 3-input mixer, and LCD interface with easy-to-use presets help working presenters, musicians, instructors, performers, and A/V providers get powerful, clean, and clear sound quickly.

The speaker provides 105° coverage from the center axis and 122 dB of continuous SPL—plenty of volume for smaller venues including houses of worship, conference centers, performance spaces, and meeting rooms. The highly efficient 2000W Class-D amplifier powers the 1.4" titanium compression driver and 8” woofer, providing crisp, detailed sound with a wide frequency range from 20 kHz down to 59 Hz.

At 27 lbs and featuring an integrated handle, the K8.2 is the most portable option in the K.2 lineup, at the expense of the additional volume and low-end range that the larger and heavier 10” and 12” models can deliver.

Three inputs are on the back. Inputs A and B feature combo XLR-1/4" connectors. Input A offers a Microphone input or a Line input—convenient if you’re using a mixer to combine multiple input sources. Input B offers a Mic/Hi-Z selection, with the Hi-Z input designed for guitars. Input C features a stereo 3.5mm TRS auxiliary input for connecting portable audio devices including phones and MP3 players.

Individual gain controls on the inputs allow the speaker to function as a 3-channel mixer. Combine two microphones for presentations, or combine a mic, instrument, and backing tracks for singer/songwriter gigs. All the PA speakers in the K.2 Series can also be used as floor monitors, giving them added versatility.

Inputs A and B also feature XLR Thru-Outputs for daisy-chaining to additional speakers or other audio equipment. All three mono inputs are mixed to a mono signal internally and are passed-thru the Mix Out XLR connector. For a true stereo L/R operation, two K8.2s are needed with each to receive independent the left and right signals respectively.

QSC's Directivity Matched Transition (DMT) matches the angle of the woofer and the horn to ensure consistent, high-quality sound across the entire coverage area. The Intrinsic Correction techniques ensure a smooth power response, resulting in accurate performance in a wide range of acoustic spaces with little or no EQ. The K8.2 includes a power cord.
