2-Channel Powered Amplifier, 800W, 70V Output

 

The 70V CX-1202V 2 Channel Direct Output Power Amplifier from QSC is a two-channel, transformerless, 70V output amplifier. It features PowerLight switch-mode power supply technology and has an integrated security cover designed for tamper-proof installation. This unit has a variable speed fan to maintain low noise, and 1 dB detented gain controls for fast and accurate gain settings. The active inrush limiting is designed to eliminate AC inrush current, and a class H complementary bipolar output circuitry is integrated for high efficiency.

 


The CX-1202V features XLR and detachable Euro style input connectors and a barrier strip output connector. It also has an HD15 DataPort connector for Q-Sys and QSControl computer control and monitoring, as well as a DIP switch control for clip limiters, high pass filters, and bridge-mono & parallel operation. The selectable high pass filters protect speakers and prevent speaker transformer saturation. The unit's front panel indicators include signal, clip, protect, and bridge mono and parallel input LEDs. Comprehensive protection circuitry with DC, infrasonic, thermal overload, and short circuit protection is also featured. This unit is rackmountable and 14" deep for reduced rack cost and floor space. It is RoHS compliant and cULus listed.
