  • The CX 2-Channel 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.


    • 8 models to meet your exact power requirements
      • Three 70 volt direct models
      • Five low impedance models, the CX902 and CX1102 also directly drive 70 volt loads
    • Exclusive PowerLight switch-mode power supply technology for high performance and compact size
    • 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
    • Active inrush limiting eliminates AC inrush current, removing the need for expensive power sequencers
    • XLR and detachable Euro style input connectors
    • HD15 DataPort connector for Q-Sys and QSControl computer control and monitoring
    • Dip switch control for clip limiters, high pass filters, bridge mono and parallel operation
    • Selectable high pass filters protect speakers and prevent speaker transformer saturation withminimal 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
    • Comprehensive protection circuitry including DC, infrasonic, thermal overload and short circuit protection
    • Class H complementary bipolar output circuitry for high efficiency (CX702, CX902, CX1102 & CX1202V)
    • Optional external transformer accessory pack for isolated 70 and 100 -volt outputs (converts CX302 to 400 watts per channel isolated output)
    • Compact size - all models are only 2 rack units high and 14" deep for reduced rack cost and floor space
    • Light weight - all models weigh only 21 pounds (9.5 kg) for easier racking and shipping
    • 3-year warranty plus optional 3-year extended service contract
    • All CX Series amplifiers meet the European Union's, 2006 RoHS directive to restrict the use of hazardous materials used in electronic devices.
