Features

Features

  • Cooling design exhausts hot air out the front, keeping the rack cool. Flow-through heat sinks require no filters that could become clogged.
  • Front panel LED power, clip, -10 dB, and signal present indicators for system monitoring and troubleshooting.
  • Speakon® NL-4 output connectors provide a positive-locking speaker connection.
  • 21-position front-panel gain controls for precise, repeatable amplifier adjustment.
  • Balanced XLR inputs with parallel TRS connectors accommodate all common input connectors and support loop-through operation.
  • Patented PowerLight power supply technology with other patents pending.
  • Value combined with uncompromised PLX technology, quality and performance for applications that don't require bridged or 2 ohm stereo operation.
  • Power ratings up to 900 watts per channel @ 4 ohms.
  • Clip limiting protects speakers; thermal limiting maintains operation even during abnormal overloads.
