Message me if you have any questions Item is sold as-is Thank you 2 Ohms: 450 W per Channel 4 Ohms: 250 W per Channel 900 W Bridged 8 Ohms: 170 W per Channel 500 W Bridged 16 Ohms: 340 W Bridged Designed for a space and energy efficient working life in a facility rack, QSC has equipped the CX254 with a varispeed fan cooling system, featuring rear to front airflow exiting through the front panel grill, and the uniquely efficient Powerwave technology for the switching power supply. The Powerwave design sends current to the amp's power circuitry by charging the supply rails a staggering 230,000 times a second via a very low impedance circuit. The result is a consistently clean signal, and efficient, predictable power distribution that contributes to lowered thermal heat buildup and improved signal reproduction.The CX254 is loaded with rear panel controls and front panel indicators, including dedicated, detented rotary gain control knobs, LF filter switches, and clip protection activation. An HD15 Dataport is located on the rear panel for computer-integrated remote control and system updating, using QSCcontrol software.The CX254 incorporates the design, cost-effective operation, and performance features that QSC is able to implement after three decades of experience building amplifiers serving all professional sound markets.
