In many applications an O-Line array can be driven using only one amplifier channel, with simple EQ and limiting the only processing required. It can now also be taken into a new dimension of coverage, consistency and control when used with an iK81, or with a combination of VIA2004 amplifier and DX4.0 controller, to independently control and power each individual enclosure. This unlocks the full potential of O-Line — further refining coverage consistency and increasing the ability to ‘dial-out’ the influence of the room by accessing DISPLAY’s ‘hard avoid’ capability and electronically adjustable coverage.

Unlike many DSP ‘steered’ columns, an O-Line array does not produce unwanted vertical sidelobes in the audio band. This is critical in reverberant environments as sidelobes firing above and below the array simply adds to the reverberant energy, impacting on intelligibility. O-Line’s ability to reproduce very high frequencies without sidelobes makes it the ideal solution for both full-range speech and music reproduction in reverberant spaces.

An O-Line array is finished in a neutral light grey that blends into the background of most architectural spaces with modular design in multiples of four cabinets. Sonically, it is very clean and musical, and capable of surprisingly high output levels for its very small size with 16 cabinets capable of an astonishing 134dB [peak] and a throw distance of up to 40 metres.

  • Modular micro line array for maximum deployment flexibility
  • Software optimised array configuration for focussed sound energy
  • Additional DSP optimised functionality for increased coverage, consistency and control
  • Sidelobe-free vertical dispersion from the high frequency section
  • Ideal for high-quality music reproduction as well as speech
  • Architecturally sympathetic design for discreet deployment
