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 Speakonô 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
