Sansui AU-20000

Integrated Stereo Amplifier (1975-77)

Description

The Sansui AU-20000 is an integrated stereo amplifier delivering a continuous 170 watts, minimum RMS, per channel, both channels driven into 8 ohms, over 20 to 20KHz bandwidth - with no more than 0.05 % total harmonic distortion.

Features include:

Eight-transistor equaliser with differential amps at initial stage gives an improved dynamic response, for an extremely accurate RIAA equalisation curve.

Triple protection circuits; temperature, DC voltage and ASO detection.

Selectable phono sensitivity/impedance, and a versatile tape monitor circuit make the AU20000 flexible and capable of handling a variety of recording and playback combinations.
