QSC K8 Active PA Speaker, 1000 Watt


The QSC K8 features an 8" woofer with a nominal coverage angle of 105 degrees, great for small-medium sized venues. Weighing just 12.2kg, the speakers in the K Series are very light compared to similar competitors, but deliver excellent sound quality, making them perfect for situations where rigging/derigging or transportation is a big consideration. Multiple mounting and suspension options allow for a wide range of live and installed applications, and multiple input options make the K8 a very flexible PA system.

High Quality Construction

The QSC K8 offers unparalleled performance with its 1.75" HF driver, breaking from the traditional loudspeaker paradigm. Premium-grade materials and advanced construction processes have been used, as well as extensive DSP processing is employed throughout, providing levels of sonic clarity and total output that defy the system's size and weight.

Flexible Connectivity

Combo XLR and 1/4" TRS inputs accept both Mic and Line Level input while a set of RCA phono inputs 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.

Rugged Housing

The K8 features a rugged ABS enclosure with a professional appearance that is at home in any application. The internal rigidity offers an additional measure of sonic clarity, making ABS a far more robust material than conventional speaker plastics with fantastic sound quality. Ease of transport and long term durability is ensured with the K8's ergonomic aluminium handles and a highly protective steel grille.

Tilt-Direct Mounting System

The unique Tilt-Direct pole cup mounting system allows acoustic energy to be kept on the audience and off reflective surfaces with the simple turn of the dial, engaging a 7.5 degree downward tilt of the speaker. This is ideal for applications where maximum coverage from a high-positioned speaker is desired.

Mixing and EQ

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) for use 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.

Extensive DSP enhances system performance

  • 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 spatially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat band pass 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 protects both the amplifier module and your performance from unnatural and destructive clipping.
