QSC QA-KW153 Powered Speaker

Overview

• 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.
