The O-line Loudspeaker

The O-Line delivers consistent audio coverage with unprecedented accuracy in a wide variety of architectural environments, using only one amplifier channel per array in many applications. By utilising a complement of unique, Martin Audio designed drivers, and mechanical alignment techniques, simple EQ and Limiting is the only processing required. A powerful software application provides extremely accurate intercabinet and array angles, in order to achieve optimum coverage over a predefined area. O-Line’s aesthetically pleasing cabinet is finished in neutral light grey.
