5. Record size detector and automatic speed
selector (DP-45F)
The record size and the speed are automatically set, when
playing 12 inch records (33 1/3 rpm) or 7 inch records (45
rpm) in the automatic play mode. The unit provides a sate-
ty measure which causes the tonearm to stop and return to
the arm rest to protect the stylus tip when there is no
record on the turntable, even if the start button is pressed.
6. DENON quartz on bi-directional servo
The ultimate in rotational accuracy is realized by the com-
bination of a magnetic pulse detector and a quartz lock,
with the addition of a bi-directional servo. On the DP-45F,
with the utilization of the bi-directional servo and a quick
response electronic brake, an even steadier rotational
performance has been achieved.
NOTE:
U.S. & Canadian models do not include cartridge.
