The Pioneer PL-520 incorporates a high precision phonomotor combining control circuitry composed of semiconductors with Hall elements in the brushless DC motor. Another feature is the high inertia platter. The speed of the platter is smooth since the Hall elements guarantee accurate position detection and the motors winding current is controlled by transistors. Altogether, these attractive features make a signal to noise ratio of more than 72dB and a wow and flutter of less than 0.03%. SPECS: Type: direct drive Motor: 8-pole, 24-slot, DC servo motor Platter: 330mm aluminium alloy diecast Speeds: 33 and 45rpm Speed control range: +-2% Wow and flutter: 0.03% Rumble: 73dB Tonearm: static-balanced type, s-shaped pipe arm Effective length: 221mm Overhang: 15.5mm Cartridge weight range: 4 to 10g Dimensions: 460 x 395 x 171mm Weight: 8.5kg Fully working okay, Very nice sounding Sonus cartridge Insured shipping
