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 number of modules (down to four) can be used for shorter-throw applications, where vertical focussing of the low/mid frequencies is less important. This scalability means that OmniLine can be used in a wide variety of applications - from bar and sports venues to churches and large public spaces. Visually, an OmniLine array is slim and unobtrusive, with soft lines that minimise its visual presence in an architectural environment.
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 arrays SPL distribution against objective target functions. This enables focussed sound energy to be delivered precisely where it is needed and kept away from reflective surfaces and ceilings. It also means that all the energy produced by the array transducers is utilised additively, at all times, unlike some flat, steered columns which need to taper the output of the outer drivers to produce wider beams. By configuring the array physically in accordance with the optimisation software, the SPL distribution of an OmniLine array can be exactly contoured to the shape of the venue, at all frequencies.
OmniLine has been developed using sophisticated, in-house mathematical modelling software which enables the acoustic field at any point to be determined from multiple acoustic elements, using a combination of actual measurements, theoretical elements or BEM (Boundary Element Method) models.
The OmniLine module consists of 2 x 3 ½" reflex-loaded, low/mid radiators either side of a central strip of 5 x 14mm HF devices in a unique, patent-pending arrangement. All drive units have been painstakingly developed from the ground up, specifically for the array module.
