The DP-55K features magnetic recording for speed detection.
Denon originated this unique motor control system, which uses a magnetic recording method for speed and phase detection.
One-thousand pulses are recorded on the inside rim of the platter with the highest degree of accuracy.
This creates a high detecting frequency eliminating phase lagging of the servo system, and accordingly over-shoot, wow and flutter.
The deck holds 99.998% speed accuracy, phase controlled by quartz oscillation.
The rotation speed is highly stabilised by a timing clock. This is very stable against changes of temperature or time.
By use of the phase-locked loop method, the speed is virtually unaffected by load or supply voltage fluctuations.
The bi-directional servo delivers quick, smooth starts and speed changes.
Smooth stopping is accomplished by the electronic brake.
