Commentary
A tape recorder capable of stereo recording and playback.
There are two 10x20cm baffle type bass speakers and two 10cm-treble satellite speakers that can be moved up to 3.2m away for directional control.
An all-silicon transistor OTL amplifier is used in the amplifier section. This amplifier section is equipped with a tone control that can adjust the high and low frequencies independently.
It supports 3 speeds of 19cm/s, 9.5cm/s and 4.8cm/s.
With an escalation drive mechanism, the pinch roller drops at the stop position when the tape is applied, allowing one touch tape loading.
To prevent accidental deletion of the tape, the recording control section is designed to be covered.
Equipped with an anti-vibration roller that absorbs the microvibration that occurs at the contact surface between the tape and the head, reducing the strain caused by vibration.
Equipped with an auto stopper that stops automatically when the tape is finished.
Can be used both vertically and horizontally.
Equipped with a tape counter that can be restored with one touch.
It can be covered with the 7-inch tape.
The sound-on-Sound feature allows you to use one channel for playback and two channels for recording (or vice versa) simultaneously.
It has a public address function.
If you press the Record button to turn it into a speaker monitor, you can use it as a loudspeaker device (microphone amplifier). You can also wake up from an FM radio.
It has a recording and re-connector terminal.
Equipped with a headphone port for binaural monitor.
Uses a Sony 2 micron head.
Equipped with a noise suppress switch that can cut the high frequency range.
You can adjust the volume of the speaker monitor.
