Description

Features

  • Numerically optimised, fully-integrated, compact touring sound system
  • Cellular array format with built-in amplification, DSP and digital networking
  • 5 dedicated Class D amplifier channels per enclosure for individual powering and DSP control of individual cells
  • Industry leading DISPLAY2.2 intelligent software interacts with onboard DSP for highly accurate array optimisation Eliminates trial-and-error array preset liary approximations
  • “Fly-by-wire” software adjusts vertical coverage electronically to cope with changing environmental conditions and last minute changes in rigging height. “Hard-avoid” areas, such as on-stage, ceilings and site perimeter, can be programmed in
  • Switched mode power supplies with PFC (Power Factor Correction) and global mains voltage operation
  • Three-way design delivers LF/MF/HF peak SPL’s of 135/135/135dB @ 1m from a single, compact enclosure
  • Fast, integral flying system for suspension of up to 24 enclosures
  • True 100° (-6dB) horizontal constant directivity, mid and high frequency pattern control. Consistent and usable out to 130° (-10dB)
  • 65Hz–18kHz ± 3dB full bandwidth frequency response

Benefits

  • Desired house-curve achieved right from power-up
  • Automatic, intelligent configuration and optimisation eliminates trial and error in system set-up
  • Improved venue-to-venue, gig-to-gig consistency and repeatability
  • Artistic changes to balance at the mix position (or elsewhere) translate directly and accurately throughout the audience
  • Exceptionally high powerdensity means tighter truck-pack for higher SPL compared to other systems
  • “Greener” audio power via PFC (Power Factor Correction)
  • Programmable leakage parameter to meet environmental noise constraints

Applications

  • Premium touring sound reinforcement for medium-size venues
  • Fixed installations in concert halls, theatres, ballrooms and HoW
  • Side hang for MLA festival and arena systems
