Description

First announced
in late 1969, the TC 666D was a quarter-track, three motor auto reverse
stereo tape deck featuring what Sony described as ‘Sony ESP (Electronic
Sensory Perceptor) – a function which automatically reversed tape direction
from right to left without the need of magnetic cue strips.
Operating at two speeds, 7½ and 3¾ ips, a frequency
response of 20Hz to 22kHz was claimed at the former and 20Hz to 15kHz
at the latter.
Other features included feather-touch solenoid transport
controls, sound-on-sound, high frequency bias and Sony’s own noise reduction
system (SNR) which, according to Sony, automatically reduced gain during
quieter passages, hence eliminating unwanted background noise.
