DIATONE DP-EC5
¥ 59,800 (released on November 1, 1978)
Commentary
An EC (electronic control) full auto player that eliminates complex operations.
The counter weight of the tone arm is equipped with an anti-resonance filter to prevent resonance.
In addition, some parts of the tone arm are made of special reinforced plastic containing glass fibers, which has high rigidity and high internal loss, thereby eliminating unwanted vibrations in the audio band.
In addition, the wide span design of the vertical pivot prevents the rolling phenomenon of the tone arm during record playing.
The tone arm is driven by two separate dedicated motors for horizontal and vertical directions.
The DP-EC5's automatic record size detection mechanism uses the same method as the DP-EC1MKII and DP-EC3. This mechanism uses optical principles to detect the record size (30cm/17cm) without touching the record, and automatically determines the needle down position and performance end position at the time of automatic performance.
Equipped with a quick response mechanism, even when the arm is ascending / descending by automatic operation, if you instruct a new operation with the button, it will move immediately to the next operation.
The turntable is driven by a direct drive system using a 20-pole 30-slot DC servo motor.
The turntable has an outer diameter of 324 mm and a weight of 1.3 kg.
The operation buttons are concentrated on the front panel so that it can be operated with the dust cover closed.
Equipped with a power switch that also serves as an arm lock.
Equipped with a safe needle tip protection mechanism even against accidental operation.
