QSC CMX800Va Power Amplifier


The CMX800Va 1200W Professional Power Amplifier from QSC is a 2RU rugged unit designed to meet the needs of system integrators. This amplifier is used in facilities such as performance halls houses of worship sports clubs gymnasiums dance venues pubs and FGM/BGM systems. The amplifier uses a powerful high-current toroidal transformer with filtering to ensure generous energy reserves. This allows the amplifier to effortlessly handle high-level transients even when driving rigorous 2Ω speaker loads.

The amplifier output sections feature rugged class H architecture. The efficient class H output section 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. This CMXa 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. SMT (Surface Mount Technology) triples small-signal component density enabling high power output in a 2 RU chassis less than 16 deep.

Unlike other designs CMXa output devices are directly mounted to the heat sink for optimum thermal coupling and cooling. The unit has the ability to directly drive 70 and/or 100V distributed loudspeakers. The CMX 800Va may be used in either stereo or mono modes. For installations requiring a transformer isolated output the CMX has optional accessories to cover your needs.

Most users do not need a license to operate a wireless microphone system. Nevertheless, operating a microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888- CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones.
