Aimed at both portable and installed system configurations, Martin Audio’s MA5.0Q amplifier is a flexible, cost-effective solution for small to medium sound systems.

Martin Audio MA5.0QOffering four channels delivering up to 5kW in a 1U-high housing, the MA5.0Q calls on technologies found in Martin Audio’s flagship amplifiers – including class-D output stages – to deliver very high efficiency. Minimum heat dissipation also makes it suited to use in hot or otherwise challenging environments.

Key features include four channels in a 1U-high at 358mm/14.1-inch depth package; minimal ‘carbon footprint’ and operational cost of electricity; 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 4Ω loads; 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 75ºC/167ºF – 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 live sound/stage monitoring, hotels, restaurants/bars/clubs, houses of worship, auditora and educational facilities.

The MA5.0Q is scheduled to ship in Q4 2015.
