The CX502 2 channel power amplifier is designed to meet the specialized needs of sound contractors. With high output power, versatile loading options, high thermal capacity and reliability, the CX Series is the ideal solution to any permanently installed sound system.

The new CX amplifiers are equipped with many contractor specific features including 1 dB detented gain controls for easily repeatable settings and a custom security cover for tamper-proof installations. Active inrush limiting eliminates AC inrush current, cutting the need for power sequencers.

CX amplifiers also include an HD15 Data Port connector to interface with QSControl, QSC's computer-controlled audio system, that allows remote amplifier monitoring and control via a standard Ethernet network.

The CX 2-channel series is a line of amplifiers designed for installation applications requiring premium sound quality and high output. Recognized by sound contractors worldwide for their reliability, CX 2-channel amplifiers feature PowerLight power supply technology reducing weight, eliminating AC mains hum and improving audio quality. The highly efficient power supply also draws less power and produces less heat resulting in added energy savings. CX 2-channel amplifiers also feature advanced amplifier control and monitoring via the Q-SYS network audio platform.
