Description

Features

  • Numerically optimised, fully integrated, touring sound system
  • Compact size and inherent scalability provide ideal “one-box” solution across rental markets
  • Cellular array format with built-in amplification, DSP and digital networking
  • 6 dedicated Class D amplifier channels per enclosure for individual powering and DSP control of individual cells
  • Industry leading DISPLAY2™ 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
  • Switched mode power supply with PFC (Power Factor Correction) and global mains voltage operation
  • Three-way all-horn design delivers LF/MF/HF peak SPL’s of 140/139/145dB @ 1m from a single, compact enclosure
  • Fast, integral flying system for suspension of up to 24 enclosures
  • True 90° (-6dB) horizontal constant directivity, mid and high frequency pattern control. Consistent and usable out to 120° (-10dB)
  • 60Hz–18kHz ± 3dB full bandwidth frequency response

Benefits

  • Unprecedented, even, house-curve balance achieved right from power-up
  • Intelligent numerical optimisation software 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 power density means tighter truck-pack for higher SPL compared to other systems
  • “Greener” audio power via PFC (Power Factor Correction)

Applications

  • Large-scale touring sound reinforcement for outdoor festivals, stadia, arenas and concert halls
  • Premium fixed installations in concert halls, theatres and sports
