Martin Audio - O-Line 4

The Martin Audio O-Line 4 is a set of 4 bi-directional micro line array modules, designed to provide maximum flexibility of use in a variety of architectural environments, from houses of worship to transport terminals.
Featuring two 3.5-inch voice coil LF drivers and five 0.55-inch soft dome tweeters, this system ensures high-quality sound reproduction.

With a frequency response of 85 Hz to 20 kHz and a rated power of 50 W AES up to 200 W peak, the O-Line 4 is ideal for delivering music and speech with precision and clarity.
The nominal impedance of 16 ohms, coupled with a sensitivity of 84 dB in LF and 92 dB in HF, allows for optimum sonic performance, while the horizontal dispersion of 100° and vertical dispersion of 5° ensures uniform coverage.

Each module is made with a 4-litre ABS moulded enclosure and a light grey perforated steel grille, providing strength and discreet integration into various spaces.
The installation system includes a set of interconnection brackets and six M8 fixings, facilitating wall or suspended mounting.
Combined with the iK41, iK81 or VIA2004 amplifiers and a DX4.0 controller, the O-Line 4 benefits from an optimised configuration for increased control of sound coverage and reduced reverberation effects, ideal for spaces requiring clarity of hearing.
