Sansui TU-7900


The Sansui TU-7900 is a precision stereo FM/AM tuner with excellent sensitivity, harmonic distortion and selectivity: three critical areas of tuner performance.

This instrument perfectly matches the characteristics of the AU-7900. The result is consistent music reproduction from broadcast signal so full and clean that you'll find it difficult to believe it's not from disc, tape or live.

Features include:

Low-noise dual-gated MOS FET amplifier and precision 4-gang frequency-linear tuning capacitor assure maximum sensitivity

PLL (phase-locked loop) integrated-circuit for the FM multiplex demodulator creates wide stereo separation (40dB at 1kHz), maintained over years of use

Automatic noise canceller

Twin tuning meters: signal strength and FM centre-of-tune

Terminals for Dolby noise-reduction unit and FM 4-channel discrete discriminator adaptor
