Pioneer CT-3
¥ 49,800 (around 1975)
Commentary
A stereo cassette deck with high cost performance by inheriting the mechanism of CT-7 and CT-5.
In order to guarantee low rotational unevenness, we have adopted a DC motor with large torque that is not affected by voltage fluctuations, and a high-precision capstan with roundness of 0.1 μ or less.
The built-in Dolby system greatly reduces the tape hissing. The built-in MPX filter circuit allows the Dolby circuit to operate stably even on FM recording tapes.
In addition, the Dolby operation indicator lamp is mounted.
It is equipped with a tape selector. When a general low-noise tape is used, both bias and equalizer are set to STD position. When a chrome tape is used, CrO is set to STD position.2Position.
When using ferri chrome tape, bias is STD and equalizer is CrO.2For more information.
The head uses a solid permalloy head that uses a hard permalloy core.
Equipped with a full auto-stop mechanism that does not burden the tape or mechanism by combining a contactless detection mechanism of the tape stop and a solenoid.
It uses a direct change operation button that can move directly to play from FF/REW without going through stop.
Equipped with a level meter.
