QSC CX-902 Overview

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.

  • Exclusive PowerLight switch-mode power supply technology for high performance and compact size
  • Custom integrated security cover for tamper-proof installations
  • Variable speed fan for low noise
  • 1 dB detented gain controls for fast and accurate gain settings
  • Active inrush limiting eliminates AC inrush current, removing the need for expensive power sequencers

  • HD15 DataPort connector for Q-SYS networked control and monitoring
  • Dip switch control for clip limiters, high-pass filters, bridge-mono, and parallel operation
  • Selectable high-pass filters protect speakers and prevent speaker transformer saturation with minimal effect on program material (33 Hz or 75 Hz)
  • Comprehensive front-panel indicators including signal, clip, protect, and QSC's exclusive bridge-mono and parallel input LEDs
  • Barrier-strip output connector
  • Comprehensive protection circuitry including DC, infrasonic, thermal overload, and short-circuit protection
  • Optional external transformer accessory pack for isolated 25-, 70-, and 100-volt outputs (converts CX302 to 400 watts per channel, or 300 watts into 25 V)
  • Compact size—only 2 RU high and 14" deep for reduced rack cost and floor space
  • Lightweight—weighs only 21 lb for easier racking and shipping
  • 3-year warranty plus optional 3-year extended service contract
  • Meets the European Union's 2006 RoHS directive to restrict the use of hazardous materials used in electronic devices
