Packed with a powerful 1000 watt amplifier, a tough yet professional looking exterior, and some really flexible input and output mixing capabilities, the K8 from QSC stands out as a great option in the active loudspeaker market. Since powered speakers get used in many different kinds of ways, the K8 has been equipped to adapt to any situation.
You can use the K8 as a stand-alone PA system, without the need for an external mixer. Simply attach a microphone directly into its XLR combo input, and if needed, attach a second sound source to the other XLR combo input, and a third source (such as an MP3 player) to the RCA stereo input. There are two gain knobs that you can use to balance the mix, and a dedicated XLR output that outputs the mixed signal to a second K8 or any other active loudspeaker. For more involved professional installations, there are designated suspension points and kits available, and a Euroblock connector to remotely control the gain.
The back panel features a couple of easy-to-use switches that allow you to accentuate a person's speaking voice, or to add depth to the bass in music. Don't let the simplicity of the controls fool you; extensive digital signal processing is going on under the hood of the K8 that help it achieve its amazing audio fidelity. There's even a tilting feature in its standard 35mm pole mounting socket that enables you to point the K8 down toward the audience, so they can fully experience and appreciate your program material. If you're looking for a reliable powered speaker that's filled with useful functions and supplies great sound, look no further than the QSC K8.

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 (fullrange 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.
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.
On-board switches provide preset EQ settings. The HF setting (fullrange 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. The LF switch can be set to NORM, DEEP for additional bass extension, or EXT SUB (fullrange models) to be used with an external subwoofer. The rear panel LED switch can be set to POWER, illuminating the front-mounted LED when the unit is powered on, OFF for applications where it is not desirable to illuminate the front LED, or LIMIT which indicates to the system operator that the clip limiter circuit has been engaged during operation.
Fullrange models are housed in rugged ABS enclosures with a professional appearance that is at home in any application. ABS is a far more robust material than conventional speaker plastics and offers an additional measure of sonic clarity due to its internal rigidity. Ergonomic aluminum handles and a highly protective steel grille complete the package for ease of transport and long term durability.
The K Series fullrange models feature a unique Tilt-Direct pole cup mounting system. A simple turn of the dial engages a 7.5 degree downward tilt of the speaker allowing acoustic energy to be kept on the audience and off reflective surfaces for applications where maximum coverage from a high-positioned speaker is desired. Integrated M10 suspension points allow for suspended applications with a K SERIES M10 KIT (sold separately) or Yoke bracket (sold separately).
- DMT (Directivity Matched Transition) provides for matched LF and HF coverage across the entire listening area, eliminating unnatural "dead" or "hot" frequency zones.
- Intrinsic Correction , first featured in our high-end line-array products maps 65-75 spacially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat bandpass target. The result is a speaker that behaves equally well across the entire sound field.
- DEEP and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequencies.
- GuardRail protection, first introduced on our GX Series amplifiers protects both the amplifier module and your performance from unnatural and destructive clipping.
