QSC CMXa Overview

The QSC CMX800Va 1200W Professional Power Amplifier is a 2 RU power amplifier designed for live sound reinforcement applications such as for performance halls, houses of worship, sports clubs, gymnasiums, dance venues, pubs, and more. The amplifier uses a powerful, high-current toroidal transformer with filtering to ensure sufficient energy reserves, allowing the amplifier to handle high-level transients, even when driving 2-Ohm speaker loads.

The output section features a 2-tier Class-H architecture, which reduces AC current draw and cuts down on unnecessary heat. Automatic current limiting protects the amplifier from damage until the short is corrected. It also features 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 case of an output circuit breakdown.

A full complementary output circuit using high-grade linear output devices generates a flat-frequency response with low distortion. SMT (Surface Mount Technology) triples small-signal component density, enabling high power output in a 2 RU chassis, less than 16" deep. The output devices are directly mounted to the heat sink to improve thermal coupling and cooling.

The unit can directly drive 70 and/or 100V distributed loudspeakers in mono or stereo modes. For installations requiring a transformer isolated output, the CMX has optional accessories to accommodate different applications. The QSC CMX800Va ships with a power cord and a security plate.

  • “Flex-Use” loading options allows CMX Series amps to drive low-impedance loads down to 2 Ohms, and can direct-drive (no output transformer) 70V and 100V distributed loudspeaker 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" 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, and enabling/disabling low-frequency filter protection
  • Low-noise variable-speed fans with rear-to-front airflow help keep amplifiers and racks cool
