property difficult also on the premium-grade 3 head deck with two heads.
The sender strike lamination core which examined and sorted out many
properties is adopted as a reproduce head.
The merit of a material is
efficiently employed by the original process which does not give stress to a
Moreover, the erase head has adopted the double gap type which used
the Low-Mass ferrite core.
The silence mechanism of a microprocessor
control is carried.
The precision type motor operated the head assembly, the
pinch roller, and the reel brake, and has prevented the deviation of the head
alignment positioned precisely.
Moreover, fail-safe which gives a damage to
neither a tapes nor a mechanism is also given to the rapid transition of
operation by the motion control by a microprocessor.
circuitry consists of dual mono-constructions in order to prevent a cross
A total of 12 regulation circuits are established in
sound-recording amplifier, and the capacity of the tapes is pulled out.
The power-source part adopted the multi-regurated power supply scheme, and has eliminated the noise interference between circuitries.
Dolbey B/C type noise reduction is carried.
Functionalities, such as a
bias fine-tune volume, a MPX filter with a defeet, an auto-repeat, timer
sound-recording / play organization, and an REC Mute, are carried.
