  • The CX Series amplifiers are designed to meet the specialized needs of sound contractors. Featuring PowerLight™ switch mode power supply technology and features like gain control security panels and 70 volt direct models. All models feature DataPorts for integration with Q-Sys or QSControl.net systems.

    The CX Series is designed to meet the specialized needs of sound contractors. Eight models have been designed from the ground up, combining QSC's exclusive PowerLight® technology with specific features to meet the requirements of fixed installations. With high output power, versatile loading options, high thermal capacity and proven reliability, the CX Series is the ideal solution to any permanently installed sound system.

    The 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.


    • Three models that range in power from 170 watts to 450 watts per channel
    • Compact size—all models only 2 RU and 14 deep for reduced rack cost and floor space
    • Bridgeable channels 1 + 2 and 3 + 4, for maximum flexibility
    • Active inrush limiting eliminates AC inrush current, removing the need for expensive power sequencers
    • HD15 DataPort connector for Q-Sys and QSControl computer control and monitoring
    • Custom integrated security cover for tamper-proof installations
    • Variable-speed fan for low noise
    • 1-dB detented gain controls for fast and accurate gain settings
    • Detachable Euro style input connectors
    • DIP switch control for clip limiters, high pass filters, bridge mono and parallel operation
    • Exclusive PowerLight switch-mode power supply technology for high performance and compact size
    • Selectable high-pass filters protect speakers and prevent speaker transformer saturation with minimal effect on program material (33 Hz or 75 Hz on non-V models, 50 Hz or 75 Hz on V models)
    • Comprehensive front panel indicators including signal, clip, protect and QSC's exclusive bridge mono and parallel input LEDs
    • Barrier strip output connector
