QSC CMX2000Va Power Amplifier


The amplifier uses a powerful high-current toroidal transformer with filtering to ensure sufficient energy reserves. This allows the amplifier to handle high-level transients even when driving 2Ω speaker loads. The amplifier output sections feature 3-tier class H architecture. The 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.

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 3RU chassis less than 16 deep. The output devices are directly mounted to the heat sink to improve thermal coupling and cooling. The unit has the ability to directly drive 70 and/or 100V distributed loudspeakers. The amplifier may be used in either stereo or mono mode. For installations requiring a transformer isolated output the CMX has optional accessories to accommodate different applications., CMX2000VA

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.
