Commercial Power Amplifier
CMXa Series amplifiers represent an economical and rugged power amplifier solution for installed sound applications. There are four CMXa models to choose from (CMX 300Va, CMX 500Va, CMX 800Va, and CMX 2000Va). The CMX amplifiers provide flexible input and output connectors making them ideal for use in projects such as performance halls, houses of worship, sport clubs, gymnasiums, dance venues, pubs, and FGM/BGM systems. The CMXa Series provides unmatched performance and user options at an affordable price point.

คุณสมบัติ
- “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
