Martin Aduido W8LCDI

Install Line Array Systems

Martin Audio Install line array systems combine innovative horn-loading techniques with line array technology to produce extremely powerful systems with maximum dynamic impact.

By combining proven and patentable driver-loading techniques with no-compromise vertically-coupled waveguides and true constant directivity horns, the Martin Audio line arrays achieve levels of efficiency and coverage consistency not usually found in this popular format.

All Martin Audio line array systems employ dedicated, horn-loaded cone-driven mid-range sections for highly intelligible voice projection. Toroidal phase plugs optimise the acoustically correct horn designs to provide the precise pattern control and very low distortion that is simply unobtainable from traditional compression driver designs.

This series, offering the same performance as the touring line array systems, has been designed with custom flyware tailored to the needs of fixed installations. Hinging at the front rather than the rear, the rigging system minimises gaps between the acoustic elements which would otherwise interfere with the continuous column effect. The inter-cabinet splay angles are easily selected by sliding links at the rear of the enclosure.

Martin Audio line arrays – in a class of their own.


Martin Aduido W8LCDI

* 3-way tri-amp all-horn-loaded 12" downfill for W8LC

* Compact, Vertically Arrayable Three-Way Enclosure

The Martin Audio W8LCDI is a compact, wide dispersion, vertically arrayable enclosure designed for the fixed installation market. It can be used individually and in small quantities for short to medium throw (up to 40 metres) applications as well as a downfill element for the W8LCI. Its 20º vertical dispersion requires fewer cabinets to cover the same area as a conventional line array element, yet it still benefits from the smooth, predictable coverage of a vertically coupled system.
