Description

EM Acoustics HALO-A Large format line array element

 

HALO Arena is designed to produce the same staggering results as HALO Compact, but in a package more suited to larger events. The same core design principle of the maximum headroom possible means that HALO Arena delivers a consistent performance across all SPL levels. HALO-A has been built for touring – but is equally at home in large format fixed installations.

A single HALO-A exhibits a flat, free-field frequency response from 48Hz to 19kHz (±3dB) and a phase response which is ±20 degrees between 150Hz and 18kHz. Due to the unique loading technique applied to the low frequency drivers, combined with the high frequency waveguide, the dispersion pattern control is maintained down to 250Hz.

 

FEATURES

  • Signature EM Acoustics ‘maximum headroom’ design approach ensures consistency of performance regardless of SPL
  • Extremely consistent horizontal dispersion pattern across the operating frequency band
  • Enclosure coated with 3-step polyurethane process ensures weather-resistance and resilience to impact damage
  • Powder-coated corrosion-resistant steel grille
  • Intelligent internal bracing combined with unique low-loss porting structure
  • Black, white and RAL custom colour finish
