The CMX 500Va is an economical and rugged power amplifier designed to meet the needs of system integrators. It is based upon the proven, rock-solid, reliable performance found in the award winning RMX Series.

The CMX 500Va feature set is designed for wide-ranging application in facilities such as performance halls, houses of worship, sports clubs, gymnasiums, dance venues, pubs, and FGM/BGM systems. The CMX 500Va provides unmatched performance, the right power for the job and an affordable price point.

Proven and Reliable Power Plant

CMX 500Va amplifier incorporate everything QSC has learned in more than forty years of striving to deliver worry-free operations without failures. The design of these amplifiers starts with our world-class power supplies. The CMX 500Va uses a powerful, high-current toroidal transformer and filtering to ensure generous energy reserves. This allows the amplifiers to effortlessly handle high-level transients, even when driving abusive 2 ohm speaker loads.

CMX 500Va amplifier is protected from damage from shorted outputs. Automatic current limiting protects the amplifier from damage until the short is corrected. CMX 500Va amplifier also feature DC protection systems to prevent loudspeaker damage inthe unlikely event of an output transistor failure. DC voltage from the power supply is never passed directly to your speakers, even in the event of an output circuit failure.

Superior Performance
The CMX 500Va amplifier delivers true and accurate studio-quality sound. A full complementary output circuit using high-grade linear output devices generates accurate, flat-frequency response with low distortion.
