Commentary
Stereo tape deck composed of 3 heads and 3 motors.
A 3-motor system has been adopted that uses dedicated drive motors for the capstan and reel respectively.
3-head configuration allows recording and playback monitoring at the same time.
High hardness permalloy head is used for the head.
Micro switch is used for 6 operation buttons to realize light operability.
It is equipped with a tape selector that can switch between two levels of bias and equalizer.
Microphone and line mixing recording is possible.
Uses a constant voltage power supply circuit that is not affected by fluctuations in power supply voltage.
