Equally versatile in both portable and installed system configurations, and with its four channels delivering up to 5,000 W, neatly packed into 1 RU weighing just over 7kg / 16lb, Martin Audio’s new MA5.0Q is a flexible, cost-effective solution for small to medium sound systems.
Benefitting from core technologies found in Martin Audio’s flagship amplifiers, the MA5.0Q sets a class standard in efficiency, leading to low power consumption, and consequently to substantial cost savings on electricity — all in an eco-friendly way.
Minimum heat dissipation makes the MA5.0Q suitable for hot or otherwise challenging environments. Delivering great sound quality, due to its unique, patented Class D output stage design, the MA5.0Q represents high value, practically as well as commercially.
Martin Audio MA5.0Q 4 canaux
The MA5.0Q delivers a number of key features. These 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;
- Optimised 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.
