UXA Amplifiers


The UXA Series of Greybox-enabled amplifiers is the perfect match for any externally-powered EAW loudspeaker. Engineered specifically to load EAW Greyboxes™, the UXA Series incorporates high performance amplification, DSP (including FocusingTM and DynOTM) and Dante networking into a compact rackmount electronics package. Multiple power levels and channel counts are available depending on the product and application. The front panel offers access to quick setup functions, with advanced control via EAW ResolutionTM, integrating prediction, control and monitoring in one platform.

  • Four/Eight channels of sonically pure Class D amplification
  • Very high power density – packs four channels or eight channels and 10kW into just 2U of rack space
  • Packed with robust protection and monitoring systems to keep the show going
  • External Breaker Protection (EBP) limits the current draw to prevent breakers opening
  • EAW minimal signal path design – Class leading sonic performance achieved by the use of state of the art Amplifier technologies and highly advanced DSP algorithms
  • 48kHz sampling frequency – Rotary encoders, illuminated buttons and graphical display provide a rapid, intuitive and user-friendly control interface
  • High speed Ethernet communications supporting DHCP, static-IP and auto-IP and direct connection to a computer
  • Linear phase HF system EQ profiling which provides perfect integration between enclosures – Dante audio networking with automatic fall over to Analog or AES3
  • AES3 inputs
  • Greybox TM enabled
