Features

  • Compact size — only 2 RU and 14" deep for reduced rack cost and floor space
  • Bridgeable channels 1 + 2 and 3 + 4, for maximum flexibility
  • Active inrush limiting eliminates AC inrush current, removing the need for expensive power sequencers
  • HD15 DataPort connector for Q-SYS networked control and monitoring
  • 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
  • Detachable Euro style input connectors
  • DIP switch control for clip limiters, high pass filters, bridge mono and parallel operation
  • Exclusive PowerLight switch-mode power supply technology for high performance and compact size
  • 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
  • High-performance Class AB+B complementary bipolar output circuitry
