Mill River Music brings you a used QSC GX7 Power Amp! This discontinued power amp from QSC works as expected; this professional 2-channel power amplifier is designed for sound reinforcement and live performance entertainment systems. It is part of QSC's lightweight and cost-effective GX Series, delivering high output power while utilizing a space-saving 2RU chassis
- Power Output: It delivers 725 watts per channel into an 8-ohm load (both channels driven) and up to 1000 watts per channel into a 4-ohm load.
- Circuitry: Uses a highly efficient 2-tier Class H circuitry system to optimize power and reduce heat.
- Weight: It is exceptionally lightweight for its power class, weighing only 15.5 lbs (7 kg) for the 120V model
- Built-in Crossover Switch: Features a 100 Hz subwoofer/satellite crossover switch. This allows you to split the input signal, sending the low frequencies (20 Hz - 100 Hz) out of Channel 1 to power a subwoofer, and the mid/high frequencies (100 Hz - 20 kHz) out of Channel 2 to power a main full-range top speaker
- GuardRail Protection: Includes QSC's proprietary GuardRail technology, which monitors the audio signal and automatically reduces peak gain to prevent clipping and speaker damage without cutting off the audio completely
- Flexible I/O:
- _Inputs:_ Balanced XLR, 1/4" TRS, and unbalanced RCA phone jacks.
- _Outputs:_ Speakon combo connectors (accepting 2-pole or 4-pole plugs and 1/4" TS plugs) and traditional favorite binding posts.
