Martin Audio O-Line Micro Line Array Module
O-Line is Martin Audio's micro line array, built for the buildings that defeat ordinary loudspeakers: churches, atria, transport halls, anywhere hard surfaces turn a normal PA into mush. Each module is a 4 litre moulded ABS enclosure holding two 3.5" LF drivers and five 0.55" soft dome tweeters, covering 100 degrees horizontally and just 5 degrees vertically.
That narrow vertical pattern is the whole point. Modules interlock with a captive bracket assembly into columns of four, eight or twelve, and Martin Audio's optimisation software sets the splay so the array puts energy on the congregation and keeps it off the ceiling and the rear wall, which is what recovers intelligibility in a long reverberation time. The column is discreet enough for a listed interior, finished in light grey with a matching perforated steel grille, and each module carries six M8 fixings for wall and flying brackets.
