Aimed at small to medium sound systems, Martin Audio‘s new MA5.0Q power amp manages to pack an up to 5,000-watt punch from a relatively small package.

The 1RU component weights just over 16 lbs., but Martin Audio says MA5.0Q benefits from core technologies in its flagship amplifiers while offering efficiency and low power consumption.

Martin Audio‘s MA5.0Q is slated to ship in mid-November 2015.

Minimum heat dissipation makes the MA5.0Q suitable for hot or otherwise challenging environments. Delivering exceptional sound quality due to its unique, patented Class D output stage design, the MA5.0Q represents high value, practically as well as commercially.

The MA5.0Q delivers key features that include: Four channels in 1 RU at 358 mm/ 14.1” depth; Minimal ‘carbon footprint’ and operational cost of electricity; More watts, less weight (up to 5,000 W in 7.3kg / 16lb); Switch mode power supply, internally switchable 230/115 V nominal; Fixed frequency switch mode amplifier output stages; Patented amplifier output filters with ripple cancellation network; Optimized for 4 Ω loads, thus ideally matching real-world scenarios in targeted applications; AC protection (shuts down power supply when AC mains voltage is outside operating range); Clip limiter (prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output); Short circuit protection (protects the amplifier from short circuit or similar events on the outputs, with automatic protection reset); Thermal protection (mutes outputs once the output devices reach 75 ºC / 167 ºF—automatic unmute once temperature is down to 65 ºC / 149 ºF); Temperature controlled, continuous variable speed fan, and front to rear airflow.

The target markets for the new amplifier include: stage monitoring; hotels, restaurants and bars; visitor attractions; houses of worship; auditoriums; educational facilities; live sound and night clubs.
