Yamaha YP-D71 Owner's Manual page 2

Yamaha thanks and congratulates you on your purchase of the YP-D71 stereo turntable unit. The YP-D71
uses a PLL circuit (phase·locked loop) with an integral quartz crystal oscillator for the servo control which
is the heart of a direct drive turntable. The yp·D71 represents the ultimate both in accuracy of the speed
of rotation and in realism of the reproduction which it gives.
It represents a combination of all Yamaha's tremendous resources in turntable-unit construction
technology: photo-electronic detection for the auto-up function, a high-sensitivity tonearm, heavy weight
turntable platter, and a cabinet in which resonances have been suppressed.
To ensure a long service life from your yp·D71, please read this owner's manual carefully.

Quartz Oscillator Phase-Locked Loop Control
This system (often abbreviated to Quartz PLL)
controls the speed of rotation of the motor by
using a quartz crystal oscillator, 'locking' it for a
dramatic increase in accuracy.
A Yamaha-Developed PLL IC
The integrated circuit (IC) used in the YP-D71
gives the highest possible accuracy in speed, with
freedom from temperature-induced drift. This
unique element was specially developed by
Yamaha.
Non-Contact Photo-Electronic Speed Detection
Auto-Up
As the cartridge stylus enters the innermost
groove, the tonearm lifts automatically and the
power is switched off.
2
The photo-electronic detector and the auto-up
circuit ensure smooth functioning.
Heavyweight Turntable Platter and Mat
The turntable platter is heavy, 1.8 kg (4 Ib),
and has a high moment of inertia (230 kg-cm
2
including the rubber platter mat). This ensures the
minimum possible wow and flutter and smooth
rotation.
High-Sensitivity Tonearm
This highly sensitive S-shaped tonearm features
ideal lateral balance and uses a dynamic damping
system that together with a zinc die-cast arm base
holds resonance to a minimum. Excellent tracking
characteristics mean you hear all the music, with­
out distortion.
