User manual DENON DP-60L

[. . . ] The history of Denon turntables commenced in 1910 with the production of Japan's first gramophone and peaked in 1939 when Denon developed a disc recorder for NHK. [. . . ] In 1970, Denon developed its own high-torque AC motor for low speeds where speed was controlled by highly precise detection of magnetic pulses recorded around the perimeter of the platter. Denon incorporated this epoch-making servo technology in its development of the direct-drive turntable whose high performance and reliability represented a clear break from conventional idler and belt drive products, and earned Denon a solid position as the brand for players used at radio stations. In the following year, the turntable was adapted for consumer use, and Denon, which continued to produce direct-drive players, became an unforgettable brand of analog players among audio enthusiasts. Silicone rubber, a deadening material, has been applied over the entire reverse side to minimise vibration and suppress howling. · Quartz lock servo and direct drive, to support stable rotation The DP-60L uses a quartz lock servo that controls rotation frequency by detecting pulses of light passing through a slit inside the motor. This quartz lock servo and direct drive motor work together to ensure high-precision rotation. · Highly sensitive universal tone arm The DP-60L's tone arm is mounted on a large aluminium die-cast base whose height can be adjusted in a range of 6mm. When this tone arm is used with the machined aluminium head shell that comes with the DP-60L, unwanted vibration is absorbed and the cartridge can perform at its maximum capacity.
