Commentary
This is a cassette deck that achieves both stability and usability by adopting a 20 degree inclined slant panel.
It uses a timer standby mechanism. If you connect a timer and set the deck to a recording standby state, recording will start automatically at the desired time. In addition, the standby mechanism can be used by regenerating condition, an alarm clock can be played on a recorded tape.
In the standby state, the pinch roller and capstan are separated from each other to prevent deformation of the pinch roller.
The tape selector has three independent bias and equalizer channels.
The Dolby System is installed as a noise reduction system.
An aged dump mechanism is adopted for the cassette eject, and operability is emphasized.
The cassette lid slides upward and opens when the eject button is pressed, and the tape is set when the lid is closed.
In addition to the recording volume, there is an independent playback volume on the left and right sides.
It uses a full auto-stop mechanism that stops the mechanism when the tape ends regardless of whether it is in recording, playback, fast forward, or rewind mode.
Equipped with a VU meter.
Includes a quick review queue to help you start your tape.
Equipped with an automatic switching mechanism between line input and microphone input to improve the SN ratio during recording.
