QSC CMX2000Va Contractor power amplifier/ 2 channel, 1100 watts/ch at 8Ω, 2000 watts/ch at 4Ω, 70V/mono at 1000 Watts
The Latest CMXa Series is an rugged and economical power amplifier professionally designed to meet and reach the needs of system integrators. One of them is the QSC CMX2000Va power amplifier. It is created based upon the rock-solid, reliable, proven performance found in the award winning RMX Series. The CMXa feature sets are created meant for wide-ranging application in facilities such as sports clubs, performance halls, houses of worship, dance venues, pubs, dance venues and FGM/BGM systems. The CMXa Series is surely an affordable price point and the perfect power for the job, it is providing an unmatched performance.
Proven and Reliable Power Plant
For what the QSC has learned in their more than forty years of striving and working to deliver worry-free operations without failures those knowledge combined are what's implemented in CMXa amplifiers. With QSC's world-class power supplies is where the design of these amplifiers start. The CMXa uses a filtering and a high-current, powerful toroidal transformer ensure generous energy reserves. This is allowing the amplifiers to work lightly and still able to handle high-level transients, even when driving abusive 2 ohm speaker loads.
Depending on the power level, the amplifier outputs is featuring a rugged class H and class AB architecture. The dependable and efficient class H output sections ono the CMX 2000Va and CMX 800Va is reducing the AC current draw and cut down on waste heat. All CMXa amplifiers are designed and protected from the damage that the shorted outputs can make. Its Automatic current limiting is protecting the amplifier from damage until the short is corrected. For preventing the loudspeaker damage, in the unlikely event of an output transistor failure, the CMXa amplifiers also feature DC protection systems. Even in the event of an output circuit failure, the DC voltage from the power supply is never passed directly to your speakers keeping it totally safe.
Superior Performance
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 (3 RU for the CMX 2000Va). Unlike other designs, CMXa output devices are directly mounted to the heat sink for optimum thermal coupling and cooling.
The CMXa Series is available in four models. Three 2-rackspace models range in power from 300 to 800 watts per channel at 4 ohms. One 3-rackspace model provides 2500 watts per channel at 2 ohms. All four models feature a compact chassis less than 16” deep.
The V in the model name designates the ability to directly drive 70-volt and/or 100-volt distributed loudspeakers. The CMX 300Va and CMX 500Va must be configured for bridgedmono operation in order to directly drive high-impedance systems while the CMX 800Va and 2000Va may be used in either stereo or mono mode.
For installations requiring a transformer isolated output, the CMX has optional accessories to cover your needs.
Features
- “Flex-Use” loading options allows CMX Series amps to drive low-impedance loads down to 2 ohms, and certain models can direct-drive (no output transformer) 70V and 100V distributed loudspeaker systems
- “Flex-Use” input connectivity choices including actively balanced barrier strip, XLR, or ¼" TRS
- “Flex-Use” output connectivity choices include NL4 Speakon™ and detachable terminal block
- Rack mountable with chassis less than 16" (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, and enabling/disabling low-frequency filter protection
- Low-noise variable-speed fans with rear-to-front airflow help keep amplifiers and racks cool
