Product Description


Martin Audio O-line

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. OmniLine's aesthetically pleasing cabinet is finished in neutral light grey.

Each O-Line array is constructed by connecting together multiple array modules. Up to 32 modules can be connected where both high output and vertical focussing down to low/mid frequencies are required. Smaller numbers of modules (down to 4) can be used for shorter-throw applications, where vertical focussing of these frequencies is less important.

Rather than applying DSP to a traditional column, O-Line’s vertical beam-forming is achieved by physically articulating individual array modules to curve the array. The actual array configuration for a specific venue is determined by powerful, patent pending optimisation software which makes intelligent judgements about the ‘goodness’ of the array’s SPL distribution against objective target functions.

O-Line uses a line of five custom-designed dome tweeters, with a spacing of only 21mm between each element. The result is sidelobe-free vertical dispersion from the high frequency section.

The ‘cones’ of the custom-designed LF drivers are sculpted from an ultra-light, stiff material and precisely follow the ideal contour of the HF horn walls (patent pending). This provides constant horizontal directivity from low mid, right up to extreme high frequencies.
