    4-Channel Low-Z Power Amplifier

    Features
    • Compact size — 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 networked 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)
    • 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
    • High-performance Class AB+B complementary bipolar output circuitry
    • Lightweight—all models 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.
