EFFICIENT NEW MA SERIES AMPS DELIVER SUPERIOR AUDIO

Compared to conventional amplifiers, the new Martin Audio MA Series models offer unparalleled levels of efficiency, delivering an astonishing 95% of the input power where it is needed, straight into the speakers with a mere 5% loss dissipated as heat. Such advanced technology enables a huge reduction in size and weight. One particular feature of this efficiency is that it is virtually independent of output level compared to conventional designs, which typically achieve their best efficiency only at full rated output power.

Crystal clear high frequencies and a tight, perfectly defined low-end ensure superbly transparent reproduction of the audio signal. Patented design features ensure that parameters such as distortion, frequency response, slew rate, damping factor and bandwidth exceed the figures of the majority of competitors‘ products in this class.

The three new MA Series models use Pulse Width Modulation (PWM) technology to achieve higher efficiency. A PWM converter works as a high frequency sampler, converting the variable amplitude of the input signal into a digital pulse at the output. This is then converted into an analog signal with a unique, patented output filter, which is how the extremely low THD and Intermodulation figures are achieved.

The Switch-Mode power supply ensures the lowest possible weight and contributes to the efficiency. It incorporates Power Factor Correction that maintains a steady current draw on the mains supply. Other switch-mode designs suffer from a spiked current draw that can lead to audible degradation, particularly driving low frequencies at high power with less than perfect mains supplies. The new MA models are virtually immune to mains voltage variations and can be used directly on any worldwide mains voltage standard without adjustment.

The combined efficiency and advanced PSU design means that these new models have phenomenal current drive capability. Two-ohm loads may be driven without any compromise making a reduced amplifier count a realistic proposition for many applications

The new MA Series models also feature comprehensive DSP functionality accessed via the front panel controls and LCD display. Limiting, mains current draw, level and routing can all be controlled and the amplifier can be remotely controlled and monitored by a PC via an RS485 interface. An optional DSP card can be fitted to give massive additional DSP functionality thanks to on-board Sharc processing. A smart card can be used to store and load parameters between amplifiers.
