MARA is a self-powered cardioid and symmetrical line array system with a continuous power of 4200 Wrms. The MARA-80 offers a linear MAX SPL of 144 dB, a wide dynamic range, and an 80º horizontal coverage, making it the perfect solution for medium to large events. Thanks to its cardioid design, we achieve a rear attenuation of -12 dB in the range of 80 Hz – 200 Hz.
MARA-80 incorporates two 10” woofers with 3” voice coils, plus two 6” drivers in a cardioid configuration. For the midrange, we use two 8” speakers with 2.5” voice coils. For the high frequencies, it incorporates two M-78N compression drivers with 3” voice coils and a waveguide with an 80º horizontal dispersion. All components have been custom-designed and manufactured to maximize system efficiency.
The MARA Class D amplifier integrates a switched-mode power supply with power factor correction (PFC) to ensure maximum performance and efficiency, regardless of the mains voltage. Each amplifier provides a total of 4200 W RMS divided into 6 channels.
The 3-point rigging system is compatible with both MARA and MARA-SUB, allowing arrays of up to 24 MARA units and 16 MARA-SUB units to be flown. The FSSTM (Fast Set Splay) angulation system allows for angle adjustments in 1º increments, from 0º to 10º, from the stacking position, significantly reducing setup time.
