Martin Audio’s O-Line Taken to a New Dimension of Control

Martin Audio’s award winning micro line array, O-Line, has been given extra powers of coverage, consistency and control thanks to the addition of scalable resolution driven by Martin Audio’s new iKON amplifiers and updated DISPLAY array optimization software.

O-Line has long been famed as a versatile micro line array designed for a wide variety of architectural applications – from houses of worship to transport terminals. In many applications, an O-Line array can be driven using only one amplifier channel, with simple EQ and limiting the only processing required.

However, it can now also be taken into a new dimension of coverage, consistency and control when combined with an iKON iK81 eight-channel amplifier with onboard DSP to independently control and power each individual enclosure or groups of enclosures. This unlocks the full potential of O-Line — further refining coverage consistency and increasing the ability to ‘dial-out’ the influence of the room by accessing DISPLAY’s ‘hard avoid’ capability and electronically adjustable coverage to tackle the most difficult acoustic spaces.

This can also prove additional benefits for any installation. More often than not, many installations can suffer from height restrictions, and the combination of both mechanical and DSP optimization can compensate this challenge. There is also the scenario that following an installation something changes in the venue and rather than have to de-rig and re-rig, electronic optimization alone can provide a level of coverage change.

Similarly, it may be that the venue is multi-purpose with changing sizes of audience and so by using DISPLAY with VU-NET control it’s possible to have different presets to cater for these coverage changes without the need to re-rig.

Unlike many DSP ‘steered’ columns, an O-Line array does not produce unwanted vertical sidelobes in the audio band. This is critical in reverberant environments as sidelobes firing above and below the array simply adds to the reverberant energy, impacting on intelligibility. O-Line’s ability to reproduce very high frequencies without sidelobes makes it the ideal solution for both full-range speech and music reproduction in reverberant spaces.

An O-Line array is finished in a neutral light grey that blends into the background of most architectural spaces. with modular design in multiples of four cabinets. Sonically, it is very clean and musical, and capable of surprisingly high output levels for its very small size, with 16 cabinets capable of an astonishing 134db [peak] and a throw distance of up to 130 ft.

Dom Harter, Managing Director, commented: “O-Line has been a tremendous servant for the company, not only for its prowess with challenging acoustic spaces, but also because it laid down the ground work for the development of MLA technology. It’s fitting that events have come full circle, and that recent developments of Wavefront Precision and iKON amplifiers that borrow so much from MLA, have now enabled extra powers of coverage, consistency and control for O-Line—making it the definitive column micro array solution.”

A fully-optimized O-Line will be debuting at ISE, 2018, Hall 7 Stand K190 and in Demo Room E104 near Hall 10.
