[. . . ] CMX Series Professional Power Amplifiers CMX300V | CMX500V | CMX800V | CMX2000V Contractor "Flex-Use" Specific Features The CMX Series is packed full of professional features that increase performance and flexibility. · "Flex-Use" loading options allow you to drive low-impedance loads down to 2 ohms and certain models to drive 70 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 SpeakonTM 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, and the additional choice of enabling/disabling low frequency filter protection · Low-noise variable-speed fans with rear-to-front airflow keep amplifiers and racks cool The New CMX Series is an economical and rugged power amplifier designed to meet the needs of system integrators. [. . . ] This allows the amplifiers to effortlessly handle high-level transients, even when driving abusive 2 ohm speaker loads. The amplifier output sections feature rugged class AB and class H architecture depending on power level. Efficient class H output sections on the CMX800V and CMX2000V reduce AC current draw and cut down on waste heat. Automatic current limiting protects the amplifier from damage until the short is corrected. CMX amplifiers also feature 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 the event of an output circuit failure. Superior Performance The CMX 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 CMX2000V). Unlike other designs, CMX output devices are directly mounted to the heat sink for optimum thermal coupling and cooling.
