Description

The CS-300 was a two-speed, half or quarter-track stereo machine, the top of the Sony range in the early 60’s and among the last of their big tube models.  This recorder was marketed in Britain as the Sony 521.

Driven by a single hysteresis-synchronous drive motor, the Sterecorder
had two VU meters, separate level controls for mic and line inputs which
allowed mixing (a feature which was on Sony machines right up to the 70’s),
automatic tape-lifters to protect tape & heads during fast forward
and rewind, and auto shut-off.
Other features included a digital tape footage counter, instant stop
(pause) control, push-button transport control with record safety lock
and a contour switch similar to a “loudness” control which gave
an 8dB bass boost to compensate bass response at low listening levels.
