Visual Sound, Inc. Two-way micro line array module OmniLine

Martin Audio Limited OmniLine® 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 OmniLine 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, OmniLine'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. OmniLine 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.
