WE APPRECIATE IT!QSC GX Series amplifiers are 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. Its all here _ dramatic styling, easy hookup and adjustments, excellent audio quality and QSC reliability. QSC GX amplifiers deliver just the right amount of power to the most popular speakers used by entertainers. Most loudspeaker manufacturers recommend an amplifier with power output equal to the speakers Program (Music) Power rating or two times (2 x) the Continuous (RMS) Power rating. The GX3 is ideal for speakers in the 300 watt (Program) range, supplying maximum possible power to 4 ohm and 8 ohm loads.Technical NotesThe QSC GX3 uses the latest evolution of the QSC Grounded Collector output system, for optimum cooling of the critical power transistors. A true Class B biasing system combines maximum thermal efficiency with excellent audio performance. GuardRailéGuardRail 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.Features:Power levels matched to the most popular speakers used by entertainers Optimized for maximum real-world headroom into 4 ohm and 8 ohm speaker systems Inputs: XLR, 1/4 TRS and phono input connectors for compatibility with any source Outputs: Speakonå combo accepts, 1/4 (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 / 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 GuardRailé 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 Specifications:8 ohms / 1 kHz (both channels driven) 300 W8 ohms / 1 kHz (single channels driven) 350 W4 ohms / 1 kHz (both channels driven) 425 W4 ohms / 1 kHz (single channels driven) 500 WDistortion (typical) 20 Hz - 20 kHz, 1 dB below rated power:_8 ohms: less than 0.05%; 4 ohms: less than 0.1%Signal to Noise (20 Hz - 20 kHz)_ 100 dBInput Sensitivity 1.2 VrmsVoltage Gain (8 ohms)_ 32.2 dB_ 34.4 dBOutput Circuitry Class BPower Requirements (1/8 power, pink noise at 4 ohms, 120V)_ 6.3AFrequency Response 20 Hz - 20 kHz, +0, 1 dBDynamic Headroom (4 ohms) 2 dBDamping Factor (8 ohms) 100Input Impedance (ohms)_ Greater than 20k (balanced)Maximum Input Level_+24 dB (16 Vrms)Input Connectors (each channel) 3-pin XLR and 1/4 TRS, balanced, parallel; Phono, unbalancedOutput Connectors (each channel)_ Speakonå, 1/4, Binding PostsAmplifier and Load Protection Short circuit, open circuit, thermal, RF protection; Load protected against DC faultsFront Panel Controls and Indicators_ Gain controls, 21 detents; Red Clip LEDs, proportional, 0.1% THD threshold; Green Signal LEDs, threshold -35 dB; Blue Power LED, AC onRear Panel Controls Full Range / Crossover switch; 100 Hz, 3rd order LP (sub), 2nd order HP (top) Track Page Views WithAuctivas Counter
