      The Martin Audio MA3.0 amplifier technology has changed the way the world looks at professional audio amplification. No other amplifiers come close for applications demanding high power and long term reliability. Thanks to amazing reductions in heat output along with reductions in weight and the specific high output power, MA3.0 amplifiers can be used in an unlimited range of applications such as concert touring, opera houses, theatres, churches, cinema, theme parks, television sound stages and stadiums.

      More sound and less weight
      Compared to a conventional amplifier, Martin Audio MA3.0 technology offers very high efficiency and delivers more power to the loudspeakers with greatly reduced heat dissipation. This greater efficiency enables dimensions, weight and power consumption to be reduced. The output stages of the amplifiers typically run at 95% efficiency, dissipating only 5% of the input energy as heat. One of the most interesting characteristics is that MA3.0 efficiency is almost independent of output level. Conventional amplifiers achieve their best efficiency only at full rated power output. Since standard music has an average power density of 40% of the maximum level, conventional amplifiers can easily generate 10 times more heat than MA3.0 amplifiers for the same volume of sound.

      Superior Sound-Sonic Accuracy
      Crystal-clear highs and a tight, well-defined low end: the most accurate reproduction of an audio signal. Patented design features ensure very high performance over parameters such as distortion, frequency response, slew rate, power bandwidth and dumping factor.

      Totally Digital with High Reliability
      The MA3.0 series is based on PWM technology that has been used for 30 years or more in power supplies and inverters. PWM provides high reliability, small size, low weight and high efficiency. A PWM converter works as a high frequency sampler, converting the variable amplitude (audio) signal into an impulse sequence with average value equal to the audio input. MA3.0 amplifiers use very high sampling frequencies to obtain high performances across the audio band.

      Compact & Lightweight
      Martin Audio MA3.0 amplifiers offer incredibly compact dimensions are very lightweight making them excellent for applications where space and weight saving are important. They also offer excellent ease of use.

      The Show Always Goes On
      The MA3.0 is completely protected against every possible error in operation and are designed to work under every condition. They will deliver maximum power with maximum safety and increased long-term reliability. Anticipating potential problems at the design stage means your show always goes on!
