  • Designed for permanently installed sound systems where rackspace is at a premium, QSC's CX168 provides unprecedented levels of channel density for multi-channel amplifiers. It provides 8 channels with 130 watts per channel at 8 Ohms. Each pair of channels may be bridged to configure these amplifiers as 4, 5, 6, or 7 channel units. It features DataPorts for remote amplifier management or signal processing, incorporation of QSC's legendary PowerLight technology, and delivery of our unmatched reputation for quality and reliability.

    QSC's PowerLight technology takes your audio to an entirely new level. Delivering tighter bass and clean, transparent highs, PowerLight also cuts waste heat, boosts reliability, and eliminates unwanted noise and hum. PowerLight is a revolutionary switching power supply technology that provides ample current to the audio power circuitry by charging the supply rails 230,000 times per second through an ultra-low noise impedance circuit. Unlike amplifiers that use conventional supplies, the audio signal is never starved prematurely and remains crisp and clean.

    Key Features:

    • 130 watts per channel at 4 Ohms
    • 8 channels in sets of 4 pairs
    • Channel pairs bridgeable for maximum flexibility
    • 1 dB recessed detented gain controls for fast and accurate settings
    • Detachable Euro style input and output connectors
    • Selectable high-pass filters protect speakers and prevent speaker transformer saturation with minimal effect on program material (33 Hz or 70 Hz)
    • Comprehensive front panel indicators including signal, clip, bridge mono and parallel input LEDs
    • Fully protected - including DC, infrasonic and ultrasonic, thermal overload and short circuit protection
    • 3-year warranty plus optional 3-year extended service contract
    • RoHS compliant

    Additional Features:

    • Compact size - only two rack spaces and 14" deep for reduced rack space
    • Exclusive PowerLight switch-mode power supply technology for high performance and compact size
    • Active Inrush Limiting eliminates AC inrush current, removing the need for expensive power sequencers
    • Four HD15 DataPorts (one per channel pair) for QSControl computer control or QSC's signal processing accessories
    • Custom integrated gain control security cover for tamper-proof installations
    • DIP switch control for clip limiters, high-pass filters, bridge mono and parallel operation
    • High-performance Class AB+B complementary bipolar output circuitry
    • Light weight - only 21 pounds (9.5 kg) for easier racking and shipping
    • All CX Series amplifiers meet the European Union's, 2006 RoHS directive to restrict the use of hazardous materials used in electronic devices.
