The Sansui AU-719 is a stereo integrated amplifier manufactured in Japan from approximately 1978 to 1981. It provides separate preamplifier and power-amplifier sections that can be used together or separated, two speaker-system connections, and phono inputs for MM and MC cartridges. Its controls include selectable bass and treble turnover frequencies, a subsonic filter, loudness compensation, and muting.
