GX5 Professional Stereo Power Amplifier description:

The QSC GX5 550W PA Amplifier is ideal for professional entertainers who require maximum performance and portability on a limited budget.

The QSC GX5 features dramatic styling, easy hookup and adjustments, excellent audio quality and QSC reliability. The GX5 delivers 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 speaker's "Program (Music) Power" rating or two times (2 x) the "Continuous (RMS) Power" rating.

The QSC 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.

QSC GX5 main features include:

  • Power levels matched to the most popular speakers used by entertainers
