This 2-channel low-impedance power amplifier boasts 500 watts per channel at 4 ohms, and its channels are bridgeable for maximum flexibility. A PowerLight switch-mode power supply yields incredible performance for a 2U-sized unit. Active inrush limiting eradicates AC inrush current, eliminating the need for expensive power sequencers. Detented front-panel gain knobs for each channel make accurate volume adjustment a breeze, while highpass filters protect your speakers with minimal effect on program material. At Sweetwater, we appreciate the CX502’s Q-SYS networked capabilities for control and monitoring, and its comprehensive front-panel indicators are ideal for at-a-glance confirmation of your settings. The CX502 includes an integrated gain control security cover for tamper-proof installations, and contains safeguards against short circuits and DC, infrasonic, ultrasonic, and thermal overload.
