O-Line

Features and Applications

Product Details O-Line

O-Line is a modular micro line array for architectural music and speech reinforcement, from houses of worship to transport terminals. Small two-way modules combine innovative acoustics with software-selected array geometry to focus sound on a defined audience area. The design is intended to preserve sound quality while limiting visual intrusion.

Each module contains two 3.5-inch LF drivers and five 0.55-inch soft-dome tweeters. Its nominal pattern is 100° horizontal by 5° vertical per module; complete array coverage is determined by the assembly rather than this single-module figure.

Coverage control and system resolution

Many O-Line applications can use one amplifier channel with appropriate EQ and limiting. For greater control, supported iKON configurations or VIA2004 amplifiers with DX4.0 processing can drive and process individual modules independently. DISPLAY then refines audience consistency, electronic coverage and Hard Avoid regions to reduce room influence.

The HF arrangement avoids unwanted vertical sidelobes within the audio band. This is important in reverberant interiors, where energy above and below the audience would add reflections and reduce intelligibility. O-Line therefore supports full-range speech and music in acoustically difficult spaces.

Architectural installation

The neutral light-grey array is assembled in multiples of four modules. Its small format and modular construction blend with architectural spaces, with dedicated wall and flying hardware available. Martin Audio describes a sixteen-module configuration producing up to 134 dB peak and covering throws up to 40 metres, subject to the complete system design.
