Standard KW series features

Inputs, Outputs and Mixing

Combo XLR and 1/4-inch 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. As many as 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.

DEEP

Sophisticated digital signal processing provides greater low-frequency extension while precisely protecting the woofer from over-excursion.

DMT

Directivity Matched Transition® (DMT) matches the HF coverage angle to the natural coverage angle of the woofer for uniform frequency response over the entire coverage area.

Axisymmetric Wave Guide

The axisymmetric wave guide eliminates the phase distortions of typical asymmetric horns for more natural reproduction.

1000 Watts

The same state-of-the-art, light-weight Class D amplifier module powers all the K and KW Series models.

EQ Modes

Optimize for a specific application with the simple flip of a switch.

Energy Management

Automatic standby mode conserves energy and extends the life of the loudspeaker.

LED Operation

Switch selectable: On (power indicator) / off (dark) / limit (limiter indication)

Remote Control

Easy-to-use remote gain control is ideal for installed applications.

Pro Appearance

Sleek lines and a full grille for a more professional look than other molded loudspeakers.

Locking IEC Power Cable

Help prevent unexpected interruptions.

Connectivity

Mic/line and RCA inputs along with onboard mixing controls allow greater flexibility.

Tilt-Direct Pole Mount

A simple turn of the dial is all it takes to alter the vertical directivity by 7.5 degrees.

Suspension and Mounting

With integrated threaded inserts, KW Series is equally at home in mounted or flown applications.

Threaded Pole

The KW181 subwoofer comes with a threaded pole for a snug, safe fit.

Intrinsic Correction

An exclusive QSC process that applies extensive acoustic measurements to noticeably improve audio quality.

Class D

Higher efficiency produces less heat and more sonic performance with lower overall current draw.

Protections

QSC's Guardrail technology protect your loudspeakers from overexcursion. On-demand cooling fan and thermal limiting prevent overheated electronics.
