Commentary
Mini-size cassette deck with metal tape position.
SH material is used for recording and replay, and metal tape is also supported by ensuring the linearity of the recording amplifier.
The mechanism is equipped with a dual motor drive system.
Silky touch operation is realized by the adoption of ICs.
The design is unified with Aiwa's Mini Compomy Pace7.
It has a 3-color 12-point optical display.
Linked with an electronic timer (MT-7) sold separately, it can display the remaining amount of all tapes.
Equipped with timer standby mechanism, and by connecting a timer sold separately, it is possible to record absence and automatically play back.
Equipped with auto-repeat mechanism.
Equipped with a synchro operation mechanism.
