Commentary
Equipped with D. P.S. S. and amorphous alloy head, this stereo cassette deck improves the sound quality and operability of the tape.
The head is equipped with an amorphous alloy head.
Since amorphous is non-crystalline, it has high magnetic saturation density and is less likely to be saturated during high-frequency recording. The laminated structure of ultra-thin film can minimize overcurrent loss.
The high intrinsic electrical resistance also greatly improves the frequency characteristics in the high-frequency range.
Equipped with D. P.S. S. which controls many functions by microcomputer.
You can play up to 16 tracks in front and back, one track repeat, one side full repeat, and a REC / AUTOTREK mute mechanism.
