QSC K8 Active PA Speaker, 1000 Watt Overview
Full Description
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.
