The CX-902 2-Channel Direct Output Power Amplifier from QSC is a 2-channel, low-impedance 550W output amplifier. It features PowerLight switch-mode power supply technology for high performance and has an integrated security cover designed for tamper-proof installations. 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-902 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, bridge-mono, and parallel operation. The selectable high-pass filters protect speakers and prevent speaker transformer saturation. The unit's front-panel indicators include signal, clip, protect, bridge-mono, and parallel input LEDs. A comprehensive protection circuitry with DC, infrasonic, thermal overload, and short-circuit protection is also featured. This unit is rack-mountable and 14" deep for reduced rack cost and floor space. It is RoHS compliant and cULus listed.
