Denon DP-55K

Servo-Controlled Direct-Drive turntable with bi-directional servo and electronic brake.

Description

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 un-affected 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.
