Manufacturer's Description

Inputs, Outputs and Mixing

• 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. 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 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.
