The QSC CMX800Va 2-Channel Power Amplifier 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.

Description

The CMX 800Va 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 800Va provides unmatched performance, the right power for the job and an affordable price point.

CMX 800Va 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 800Va 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 800Va amplifier is protected from damage from shorted outputs. Automatic current limiting protects the amplifier from damage until the short is corrected. CMX 800Va 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.

The CMX 800Va 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.

Features

  • “Flex-Use” loading options allow you to drive low-impedance loads down to 2 ohms and certain models to drive 70 and 100V systems
  • “Flex-Use” Input connectivity choices including actively balanced barrier strip, XLR, or 1/4" TRS
  • “Flex-Use” Output connectivity choices include NL4 Speakon and detachable terminal block
  • Rack mountable with chassis less than 16" or 40.6 mm deep
  • 1 dB recessed, detented gain controls for fast, accurate and repeatable settings
  • Tamper-proof security cover for gain controls
  • Recessed rear DIP switches for easy selection of stereo, parallel, or bridged mode operation
  • Low-noise variable-speed fans with rear-to-front airflow keep amplifiers and racks cool
