Product Details

QSC CMX 500Va 2-Ch Low Impedance / 70V Contractor Power Amplifier

The CMX 500Va is based upon the proven, rock-solid, reliable performance found in the award winning RMXa Series. The CMXa feature sets are 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 CMXa Series provides unmatched performance, the right power for the job and an affordable price point. CMXa amplifiers 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 CMXa 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. The amplifier output sections feature rugged class AB and class H architecture depending on power level.

All CMXa amplifiers are protected from damage from shorted outputs. Automatic current limiting protects the amplifier from damage until the short is corrected. CMXa amplifiers also feature DC protection systems to prevent loudspeaker damage in the 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.

The CMXa amplifiers deliver 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. SMT (Surface Mount Technology) triples small-signal component density, enabling high power output in a 2 rack unit chassis. Unlike other designs, CMXa output devices are directly mounted to the heat sink for optimum thermal coupling and cooling.

The V in the model name designates the ability to directly drive 70Vand/or 100V distributed loudspeakers. The CMX 500Va must be configured for bridged-mono operation in order to directly drive high-impedance systems.

For installations requiring a transformer isolated output, the CMXa has optional accessories to cover your needs.
