DENON DP-30L
¥ 44,800 (around 1981)
Commentary
A full auto player with a non-contact type auto lift mechanism.
Non-contact type auto lift mechanism is adopted.
The up / down speed of the arm is also controlled optimally by the electronic servo lifter.
Uses speed servo of magnetic recording detection method.
An AC servo motor is used in the drive section to achieve a high SN ratio of 78 dB.
Fine speed adjustment of ± 3% is possible.
Equipped with high sensitivity S-shaped tone arm with matte black finish.
The cabinet uses an integrally molded cabinet made of a new material, H. D.C. (High Density Compound).
H. D. C. is a mixture of special materials and heat compression molded. It has acquired a specific gravity of approximately 2 and realizes excellent howling characteristics and high strength.
In addition, since high heat treatment has been applied to processing and molding, there is no deformation even in long-term use.
The cartridge is equipped with DL-8A, MM type cartridge.
