The Sony TC756 set new records for performance of home tape decks.
Hirsch-Houck Laboratories further noted. "The dynamic range, distortion, flutter and frequency response performance are so far beyond the limitations of conventional program material that its virtues can hardly be appreciated".
The Sony TC756-2 features a closed loop dual capstan tape drive system that reduces wow and flutter to a minimum of 0,03% , logic controlled transport functions that permit the feather-touch control buttons to be operated in any sequence, at any time without spilling or damaging tape: an AC servo control capstan motor and an eight-pole induction motor for each of the two reels; a record equalization selector switch for maximum record and playback characteristics with either normal or special tapes; microphone attenuators that eliminate distortion caused by overdriving the microphone pre-amplifier stage when using sensitive condenser mics; tape/source monitoring switches that allow instantaneous comparison of program source to the actual recording; a mechanical memory capability that allows the machine to turn itself on and off automatically for unattended recording; and a full, two-year guarantee.
In addition, the TC756-2 offers 15 and 7-1/2 ips tape speeds; Ferrite & Ferrite 2-track/2-channel stereo three-head configuration; and symphase recording that allows you to record FM matrix or SQ** 4-channel sources for playback through a decoder-equipped 4-channel amplifier with virtually non-existent phase differences between channels.
The Sony TC756-2 is representative of the prestigious Sony 700 Series - the five best three-motor 10-1/2" reel home tape decks that Sony has ever engineered.
