    QSC GX5 Power Amplifier (500 Watts) Product Description

    The QSC GX5 amplifier is ideal for professional entertainers who require maximum performance and portability on a limited budget. QSC designers, headed by Pat Quilter, have optimized output and appearance while reducing raw material cost and weight. It's all here -- dramatic styling, easy hookup and adjustments, excellent audio quality and QSC reliability.

    Features:

    - Optimized for maximum real-world headroom into 4 Ohm and 8 Ohm speaker systems
    - Inputs: XLR, 1/4-inch TRS and phono input connectors for compatibility with any source
    - Outputs: Speakon combo accepts, 1/4-inch (TS) plugs or Speakon 2-pole and 4-pole plugs (connects 2 poles only)
    - Binding posts support all other speaker wiring systems
    - Minimum depth chassis (10.1 inches/257 mm)
    - Fits in compact, inexpensive effects racks
    - Lightweight -- less than 26 lbs (12.5 kg)
    - Detented gain controls for precise setting and matching of sensitivity
    - GuardRail automatically protects the amplifier and loudspeakers from damage due to temperature rise or overdrive without shutting down the show
    - Front panel LEDs monitor Power, Signal and Clipping
    - Subwoofer/Satellite crossover built-in

    Which Wattage Is Right For You?

    Most loudspeaker manufacturers recommend an amplifier with power output equal to the speaker's "Program (Music) Power" rating or two times (2 x) the "Continuous (RMS) Power" rating. The GX5 provides full performance for 500 watt (Program) speakers. Owners of popular 4 ohm loudspeakers (dual-woofer, two-way models and many subwoofers) will find the 700 watt (4 ohm) power of the GX5 an ideal match.

    QSC GX5 Technical Notes

    The GX5 uses a Class H system, based on key elements of the PLX Series, almost doubling power in the same size and weight. QSC design expertise allows the output devices to shift from low-power to high-power rails in less than a millionth of a second, ensuring that the output power is always right where it needs to be without excess loss. The QSC GX5 uses premium toroidal power transformers for reliable "mid-weight" performance. A variable-speed fan moves air crosswise through the amplifier, drawing cool air in over the power transformer, through the fan, and then over the heat sink. This keeps the transformer cool and allows a full size heat sink to fit in a down-sized chassis. As always, GX5 is fully protected from the usual hazards of the trade, ensuring stable performance and long life.

    GuardRail Limiting Protects Your System

    GuardRail protection delivers full peak power while preventing detrimental overloads. During excessive clipping, or extreme overheating, GuardRail reduces gain just enough to preserve the integrity of the music, protect the speakers and keep the audience excited, without unprofessional distortion levels or shutdowns.

    Subwoofer/Satellite Crossover

    A subwoofer reduces strain on the full-range speaker, allowing it to play louder, or letting a smaller speaker do the same job. The GX Series supports this mode with a Crossover switch that splits the full-range input entering Ch 1, sending 20 Hz - 100 Hz to the sub (Ch 1) and 100 Hz - 20 kHz to the top box (Ch 2). The front panel gain controls balance the sub and top box, while GuardRail optimizes peak power into the sub and top individually, for greater musical impact and dynamic range.
