Description
Product description This is a set of turntable DP-1000 and cabinet DK-110. A turntable that inherits the design image of the DP-3000, has a more compact appearance, and has simplified each part and reduced costs while maintaining basic performance. The drive system uses a direct drive system. The direct drive system does not have a rotation transmission mechanism like the belt drive system or idler drive system, so there is no wow and flutter or rumble caused by them. In addition, stable performance can be maintained for a long period of time because there are few parts that wear out. The servo circuit uses a speed detection mechanism based on the magnetic recording and reproducing method developed for DENON's local players. In this method, 1000 pulse signals are recorded using a special method on the magnetic material coated on the inner circumference of the turntable's rim with high precision, with a recording wavelength error of less than 0.01%, and then detected by a nearby magnetic head. . The demodulation circuit then converts it into a voltage proportional to the rotation speed of the turntable. This is compared with a reference voltage corresponding to the specified speed, and the motor torque is controlled based on the voltage difference, and the servo is servoed so that the voltage difference becomes zero, thereby maintaining the turntable at the specified speed. In addition, the speed detection signal is not only highly accurate, but also has a higher frequency (more than 500Hz) compared to other methods, so it is stable even when the gain of the servo system is increased, and the servo system has a fast response and is stable even in areas with uneven rotation. You can multiply The solid rotor type AC servo developed for direct drive also uses auto as the drive motor. This motor is the same as the one installed in the DP-3000, and has smoother rotation characteristics with less vibration than other synchronous motors or DC motors. Furthermore, consideration has been given to the motor drive waveform, resulting in almost no rumble and an S/N ratio of over 60dB. The switch uses a sliding method using a cam. The rotation speed is changed by changing the circuit constant using a switch. This speed selection switch is linked to the power switch, allowing you to select the speed and turn the power ON/OFF with one-touch operation. The switch uses special high-grade grease that is used in cameras. Equipped with an easy-to-understand built-in strobe and strobe shutter. ●Main specifications Model turntable Drive method Servo type direct drive Motor Solid rotor type AC torque motor Speed control Voltage servo with frequency detection Rotation speed 33・1/3, 45rpm Speed switching mechanism Slide switch switching (electrical switching) Start-up time: 1.8 seconds or less (1/2 rotation, 33/1/3 rpm) Wow/flutter 0.03%wrms or less (according to test records) motor board aluminum die cast SN ratio 60dB or more Turntable 30cm aluminum die-cast, 1.1kg Moment of inertia 160kg・cm2 Rotation speed adjustment range ±3% Power supply AC100V, 50Hz/60Hz Power consumption 11W External dimensions Width 356x Height 132x Depth 356mm Weight 6.8kg ★The product is in good condition, with no noticeable scratches or stains.
