Description
Sansui’s first tape deck was a three-motor unit with four heads – erase, record and two playback. The heads were described by Sansui as being of a new design, “precision quality wide-band and contourless”.
These heads permitted a higher input signal, especially in the lower frequency range, thus giving the SD-7000 a claimed frequency response of 15 – 25,000 Hz. Wow and flutter figures of less than 0.06% at 7½ ips and a S/N
ratio of 60 dB were also quoted by the makers. The deck itself was a quarter-track stereo machine, relay/solenoid operated with automatic rewind, repeat and reverse playback (hence the two playback heads).
Tape handling was advertised as excellent “….having more tape protection devices …. than can be found on any other unit now on the market…”
