MA7900 2-Channel Integrated Amplifier

Audio dreams become reality when you play your music through the MA7900 Integrated Amplifier. Combining amp and preamp capabilities, along with a Digital-to-Analog Converter (DAC) and phono section all in one space saving unit, it has the technology and features that music lovers demand.


MA7900 Features:

  • Featuring 12 total inputs - including 3 dedicated digital inputs to decode your digital music up to 32 bits and 192kHz for high resolution audio playback - the MA7900 has enough connections and modern technology to keep all your music sources connected and sounding great for years to come. The discrete, five band tone control is assignable by input and permits manual analog adjustment of your favorite recordings, allowing them to sound better than they ever have.
  • Two dedicated phono sections (1 Moving Magnet and 1 Moving Coil) can be adjusted to perfectly match your turntable and phono cartridge, allowing you to rediscover your valued record collection. The Home Theater Pass Through feature will allow for seamless integration into your existing multi-channel theater system.
  • With a healthy 200 Watts per channel, the amplifier section has enough power to properly drive virtually all loudspeakers. The included world famous McIntosh Autoformer guarantees your speakers will always receive the full 200 Watts regardless of their impedance, while Power Guard will prevent clipping that could damage your speakers. Our new High Drive headphone amplifier features increased gain and output power, and is optimized for virtually all headphone types for the ultimate personal listening experience.
  • The entire unit is housed in a beautiful polished stainless steel chassis that not only complements the classic glass front panel, but also your room decor.
