• 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 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 rack units high and 14" deep for reduced rack cost and floor space
  • Lightweight - weighs only 21 pounds (9.5 kg) for easier racking and shipping
  • 3-year warranty plus optional 3-year extended service contract
  • All CX Series amplifiers meet the European Union's 2006 RoHS directive to restrict the use of hazardous materials used in electronic devices.
