Model DP-50F has fundamentally the same mechanism as that of the DP40F. It is an automatic record player equipped with the phono motor of higher performance to attain the rotational characteristics equivalent to that of the state-of-the-art. Manual record player, and at the same time, the operational flexibility is further improved.
Newly developed electronically servo controlled tonearm truthful to the will of the listener
DP50F is equipped with a new mechanism of electronically servo controlled tonearm, the fruit of all Denon's servo technology. Without ever touching the tonearm, most delicate operation can be accomplished; you can select the program, or get the head of a band with ease and accuracy smoothly and without a touch of doubt.
The mechanism is, when the position selector on the front panel is turned, the special MC type angular control motor is servo controlled, and the arm can be smoothly moved to any optional point on the record disc. Furthermore, as this auto mechanism is of non-contact type, the sensitivity of the tonearm itself is not affected at all. No trickly movement results even if the arm is touched while it is being moved.
Convenient self-illuminating push button memorizing the record size for the convenience of the listener.
The DP50F is equipped with one-touch push button to handle locating the program head of 30 cm/17 cm record disc as well as with the positions selector. Just press one of the self-illuminating record selecting switches and than the Start switch. The tonearm moves smoothly to the position of the disc size selected and starts playing. No need to operate the position selector, quick and accurate record playing can be enjoyed.
This operation is easy to release. Just turn the locate switch On (self-illuminating type with the orange lamp to prevent misoperation). With this switch, yuo can accomplish the free operation of the position selector just as with the DP40F.
