DIATONE DP-84DA ¥ 41,800 (around 1978)
Commentary
An auto player system with a configuration in which some functions of DP-86DA are omitted.
By mounting the resonance prevention mechanism of the counterweight on the tone arm, sharp resonance that occurs in the pipe and the head shell is prevented. In addition, the counterweight has a double structure, and rubber dampers are incorporated between them. This has improved the sound resolution in the low range.
The 12-pole 24 slot brushless servomotor is adopted as a drive motor.
The auto mechanism is carried and an auto return and an auto cut are possible.
All control levers are centrally located on the front of the cabinet and can be operated with the dust cover closed.
Howling is suppressed by adopting a molding with iron powder in the cabinet and adopting a large-sized insulator.
The anti-skate mechanism and the oil dump type arm lifter are carried.
