QSC CMX300Va 200 watt Contractor Power Amplifier

QSC CMX300Va 200 watt Contractor Power Amplifier

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 1/4″ 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
