2-Channel Power Amplifier, 200W @ 8 ohms

 

The CX-302 2-Channel Direct Output Power Amplifier from QSC is a 2 channel, low impedance, 600W output amplifier. This 2RU amplifier 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.

 


The CX-302 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 and QSC's exclusive 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 rackmountable and 14" deep for reduced rack cost and floor space. It is RoHS compliant and cULus listed.

Features

  • Eight two-channel models to meet your exact power requirements
  • Three 70-volt direct models
  • Five low-impedance models; the CX902 and CX1102 also directly drive 70 volt loads
  • 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
  • XLR and detachable Euro style input connectors
  • HD15 DataPort connector for Q-Sys and QSControl computer 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 withminimal effect on program material (33 Hz or 75 Hz on non-V models, 50 Hz or 75 Hz on V models)
  • 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
  • Class H complementary bipolar output circuitry for high efficiency (CX702, CX902, CX1102, and CX1202V)
  • 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 - all models are only 2 rack units high and 14" deep for reduced rack cost and floor space
  • Light weight - all models weigh only 21 pounds (9.5 kg) for easier racking and shipping
