MA04 series Datasheet

MA04 series

In pursuit of the best sounding quality with the highest power density and equipment stability SAE Audio has developed the MA series of power amplifiers. Featuring SAE Audio high efficiency Class I™ power modules, a premium heavy-duty toroidal transformer power supply and top audio-specific electronic elements, the excellent MA series of power amplifiers can deliver an enormous amount of power with an unmatched sonic quality even on continuous operation in the most critic working conditions. Being also equipped with SAE Audio robust Ultra Low-Loading Capacity technology, the MA series is the ideal power stage for subwoofer reinforcement applications with the highest SPL equirements.


  • Premium quality heavy-duty toroidal transformer power supply.
  • High efficiency Class I™ power modules.
  • Highly sensitive CMRR balanced inputs for improved noise rejection.
  • Ultra low-load output capacity.
  • Top electronic elements for a superior sonic quality.
  • Backlit front panel controls.
  • Channel independent power and -5dB / -10dB / -20dB / clip indicators on the front panel.
  • Channel independent protection warning indicator on the front panel.
  • XLR input and signal link connectors.
  • SpeakON NL4 and binding post output connectors.
  • Input sensitivity selector on the back panel (32dB / 1v / 0.775v).
  • Routing mode selector (stereo / bridge-parallel) with status indicator on the back panel.
  • Channel independent soft-clipping selector on the back panel.


  • Mid and big sized high-end installation applications.
  • Clubs with high sound quality and power density requirements.
