QSC GX3-QSC 2-Channel Amplifier 300W per Ch at 8 Ohm, 425W per Channel at 4 Ohm

Description: The QSC GX3 professional power amplifier 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. The GX3 power amplifier is ideal for professional entertainers who require maximum performance and portability on a limited budget. This power amp is ideal for speakers in the 300W (Program) range, supplies maximum possible power to 4-ohm and 8-ohm loads, and features easy hookup and adjustments. The GX3 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. 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 audio and protect the speakers without unprofessional distortion levels or shutdowns. A subwoofer reduces strain on the full-range speaker, allowing it to play louder, or letting a smaller speaker do the same job. The GX3 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.FeaturesPower levels matched to the most popular speakers used by entertainersOptimized for maximum real-world headroom into 4- and 8-ohm speaker systemsDetented gain controls for precise setting and matching of sensitivityGuardRail automatically protects the amplifier and loudspeakers from damageSubwoofer/satellite crossover built-inSpecificationsPower: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 dBOutput circuitry: Class BPower Requirements (1/8 Power, Pink Noise @ 4 ohms, 120 V): 6.3 AFrequency 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, parallelPhono, unbalancedOutput Connectors (each channel): speakON®, 1/4", Binding PostsAmplifier and Load Protection: Short circuit,open circuit, thermal, RF protectionLoad protected against DC faultsFront Panel Controls and Indicators:Gain controls, 21detentsRed Clip LEDs, proportional, 0.1% THD thresholdGreen Signal LEDs, threshold -35 dBBlue Power LED, AC onRear Panel Controls: Full Range / Crossover switch - 100 Hz, 3rd order LP (sub), 2nd order HP (top)Cordset: 120V 50/60 Hz: NEMA-15Dimensions (H x W x D): 3.5" x 19" x 10.1" (89 x 483 x 257 mm), 2U HighNet Weight : 25 lbs.
