Sansui P-D11 Automatic Direct Drive Turntable
Made in 1984. Same as Model P-D21 (except for the color) P-mount cartridge Speeds : 33 1/3 and 45 RPM Speed locked with Frequency Generated Servo system A circuit generates a frequency that the motor works with to derive its revolution speed and accuracy. A servo is a circuit that compares the actual sensed speed (frequency) with the reference frequency and then corrects it to the reference. The Frequency Generator is the precision tachometer for the speed locking circuit that compares it's waveform output to those of the drive circuits and provides constant correction. Platter : Aluminum alloy diecast 12 inch diameter 1.43 pounds Motor : Coreless brushless DC Servo Wow and Flutter : 0.038% (WRMS) Signal to noise ratio : Better than 72 dB (DIN-B) Better than 60 dB (IEC-B) Tonearm : Statically balanced type Effective tonearm length : 220 mm (8 11/16") Dimensions : W- 16 29/32" H- 4 23/33" D- 14 3/16" Weight : 9 pounds
