QSC launched a new amplifier line at InfoComm, dubbed the CMX. The CMX Series is available in four models: the CMX 300V, CMX 500V and CMX 800V, housed in a 2RU chassis design, and the CMX2000V, housed in a 3RU chassis design with power ranges from 185 watts to 2500 watts per channel.

All models feature constant voltage output for distributed audio systems with the CMX300V and CMX500V offering it in mono-mode only, while the CMX800V and CMX2000V featuring constant voltage output in either mono- or stereo-mode. The output sections feature rugged class AB and class H architecture (depending on power level) and efficient class H output sections on the CMX800V and CMX2000V to reduce AC current. Unlike other designs, CMX amplifier output devices are directly mounted to the heat sink for optimum thermal coupling and cooling. Likewise, all CMX amplifiers are protected from damage by output short circuits with automatic current limiting protecting the amplifier from damage until the short is corrected. These amps, however, are not Energy Star-qualified or rated.
