Principales características del Amplificador QSC CMX800Va
- “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.
