Stereo cassette deck with independent bias / equalizer switching tape selector.

In order to bring out the performance of the tape to be used, it is equipped with a bias / equalizer independent switching type tape selector. Standard, chrome and ferrichrome can be used.

Equipped with a DC motor with high starting torque and good start-up.
The drive voltage of this motor is controlled by an electronic circuit that combines a transistor and a diode, so that uneven rotation caused by voltage fluctuations or load fluctuations does not occur.
In addition, since it is a DC motor, there is less induction noise than the AC type, and there is no worry of hum.

It is equipped with a permalloy solid head that has approximately 10 times more wear resistance than conventional permalloy heads.

Equipped with a full auto-stop mechanism that automatically opens when the tape ends in any state, such as recording, playback, fast-forwarding, or rewinding. Since it is a contactless system that detects the tape stop state with an electronic circuit, it does not damage the tape or burden the mechanism.
It also uses a direct change button that allows you to move from fast forward or rewind to play without going through the stop button.

Equipped with a microphone jack with mode automatic switching function.
When it is inserted into My Kujac, it automatically switches to mono circuit just by inserting it into My Kujac, and recording can be done on both left and right channels.
If you use 2 microphones, you can record in stereo.

Equipped with a playback noise filter that cuts when there is a lot of tape-specific hissing.

A slide-type memory marker is provided in parallel with the level control knob.
It is useful to set the memory marker to an appropriate level for playback immediately after recording or for repeated recording and playback operations.

Equipped with a tape running pilot that rotates according to the tape running direction and speed.
