1939...FIRST DIRECT-DRIVE TURNTABLE SYSTEM.
1951...FIRST MOVING-COIL CARTRIDGE.
1972...FIRST DIGITAL (PCM) RECORDING.
1981...DENON'S DP-60L DIRECT-DRIVE TURNTABLE.
The latest stage in Denon's refinement of direct-drive is the DP-60L Semi-Automatic Turntable. It uses a unique AC Servo motor with a quartz "clock" speed-reference to achieve exceptional torque and speed accuracy, while eliminating the corrective speed surges that degrade the performance of other direct-drive turn tables. The DP-60L is supplied with two plug-in tonearm wands one straight and one S-shaped-to assure a precise match-up with the characteristics of any phono cartridge.
The result? Musically cleaner sound, free of sonic smearing.
The Denon turntables for 1981: Six musical instruments from the company where innovation is a tradition.
In 1939, while many turntable manufacturers were trying to make the transition from horn phono graphs to electrical record players; Denon developed its first direct-drive turntable, (shown above). Denon engineers discovered that only a direct connection between motor and platter--free of the pulleys or belts found in more primitive drive mechanisms--could completely eliminate speed fluctuations that obscure musical detail.
Today many turn table makers have discovered the virtues of direct-drive. It is now the accepted means of approaching state-of the-art performance.
But only one company has had 40 years to refine the direct-drive principle. It is the same company that 29 years ago developed another technology now in widespread use: the Moving-Coil Cartridge.
It is the same company that changed the entire process of recording music by inventing digital (PCM) recording.
The company is Denon.
