The QSC Audio RMX 850 Power Amplifier stereo power amplifier provides clean, dynamic power, reliability and true studio-quality sound, at a new breakthrough price. The amplifier is packed full of professional features that increase performance and flexibility.

The power supply is the heart of any amplifier, converting raw AC power from the wall to clean DC for the audio circuitry. The RMX 850 uses a powerful high-current toroidal transformer and ample filter capacitance to ensure generous energy reserves. This makes a critical difference in sound quality, allowing the amplifier to effortlessly punch out high level transients, even when driving abusive 2 ohm speaker loads. A full complementary output circuit using the highest-grade linear output devices delivers ultra-low distortion and a ruler-flat frequency response.
