QSC K8.2 Two-Way 8-Inch 2000W Powered Portable PA Speaker with DSP Processor
The QSC K8.2 is a two-way, 8-inch powered PA loudspeaker designed for portable sound reinforcement, presentations, live performances, and professional AV applications. Its 2000W amplifier, onboard DSP, and built-in mixer provide flexible sound control in a compact enclosure.
The onboard DSP processing, three-input mixer, and LCD interface with presets help presenters, musicians, instructors, performers, and AV professionals configure sound for a variety of applications.
The K8.2 provides 105-degree conical coverage and a stated continuous maximum SPL of 122 dB, making it suitable for smaller venues such as houses of worship, conference rooms, performance spaces, and meeting rooms.
The Class-D amplifier powers an 8-inch woofer and a 1.4-inch titanium compression driver. The supplied specifications list a frequency range of 55 Hz to 20 kHz at -10 dB and 59 Hz to 20 kHz at -6 dB.
Weighing approximately 27 lb, the K8.2 is a portable option in the QSC K.2 Series. Its integrated handles and pole-mounting options support convenient transport and setup.
Inputs A and B use combo XLR-1/4-inch connectors. Input A supports microphone or line-level signals, while Input B supports microphone or Hi-Z signals for compatible instruments. Input C provides a 3.5 mm stereo auxiliary input for portable audio devices.
Individual input gain controls allow the speaker to combine multiple sources, such as microphones, instruments, and backing tracks. The internal mix is mono and can be sent to another device through the Mix Out connector.
Inputs A and B also provide XLR Thru outputs for connecting additional equipment. For stereo left/right playback, use two speakers and send the appropriate independent channel to each speaker.
QSC Directivity Matched Transition (DMT) technology is designed to provide consistent coverage across the listening area. Intrinsic Correction processing and onboard DSP functions support tailored performance in different applications.
