Pioneer PL-50LII 10680 Record Player Cartridgeless Player System Direct Drive

Description

Product description A record player with improved sound quality that reflects the sound quality improvement technology gained from high-end models. The tone arm uses a straight arm with an integrated head shell, which has a dual structure of carbon graphite, which is lightweight, highly rigid, and has excellent damping characteristics, and a highly rigid aluminum base. By carefully examining the material itself and at the same time performing vibration analysis using a computer, we have eliminated complex split resonance phenomena. The strength of the head shell and the connector at the base has been sufficiently increased to eliminate the negative effects of resonance. In order to eliminate low frequency resonance and achieve high sensitivity at the same time, a variable level silicone oil damping system is used. This has a structure in which a damping fin (ring-shaped) is submerged in the silicone oil injected into the oil cup at the top of the arm shaft to apply damping, and the equivalent mass of various cartridges and arms are appropriately matched, expanding the range of application of the arm. Furthermore, by cutting the tips of the fins at 45 degrees, the structure allows suitable braking to be applied in both the horizontal and vertical directions at the same time, reducing the Q (resonance sharpness) of low-frequency resonance. In addition, due to the synergistic effect with the mass concentration method in which the main weight of the arm is brought close to the rotation axis, cross-modulation distortion is significantly improved. The arm base uses a die-cast heavyweight arm base with a stabilizer effect. By firmly fixing the arm and suppressing partial resonance, higher resolution low frequency reproduction is achieved. In order to improve rotational accuracy, we have adopted a coreless structure that, in principle, does not cause cogging. Furthermore, by adopting the SH rotor system, which moves the rotor's fulcrum (bearing) from the bottom of the motor to just below the turntable, excellent rotational characteristics are achieved. The SH/rotor system fundamentally eliminates the inverse conical movement of the motor shaft that occurs due to the small clearance between the motor shaft and the bearing, which could not be prevented with conventional structures. In addition, in order to eliminate load fluctuations caused by the resistance that the stylus receives from the record groove, a coreless quartz PLL DC servo Hall motor with a starting torque of 1.6 kg-cm and a 31 cm diameter turntable with an inertial mass of 330 kg-cm2 are used to achieve stability that does not cause rotational speed fluctuations even under a load of 200 g of stylus pressure. Furthermore, the motor's magnetic pole switching mechanism uses three Hall elements developed by Pioneer. In addition, we eliminate minute noises by requiring micron-order machining precision for all other detailed parts. Equipped with a silent lift-up mechanism that produces no mechanical noise. This device uses a moving coil system, which applies the principle of speaker operation, to the elevation mechanism that moves the arm up and down, and is designed to operate without contact using DC voltage. In addition, a non-contact detection method is used to detect the end position of the record's sound groove using a Hall element and magnet inside the arm shaft, so there is no lateral pressure and the sensitivity of the arm is not impaired. Furthermore, a pure electronic quick stop mechanism is adopted. The cabinet uses a high-density cabinet (marble ebony finish) made of laminated solid boards, which effectively prevents the cabinet from shaking due to the reaction of the rotational moment of the high-torque motor. In addition, the insulator that supports this uses a unique low center of gravity insulator to ensure stability against external vibrations such as howling. Oxygen-free copper wire with low transmission loss is used for the tone arm lead wire and PU cord. Equipped with an S-shaped universal arm pipe (with large weight) that allows for easy head shell replacement, and the twin pipe exchange system allows you to enjoy any cartridge. In addition, carbon graphite shell-integrated straight arm pipes are also sold separately, so you can have as many straight arms as there are cartridges, and enjoy easily replacing cartridges. ●Main specifications Model Cartridgeless player system Motor Coreless quartz PLL DC servo Hall motor Drive method Direct drive Bearing structure: SH/rotor type Turntable diameter 31cm Turntable inertia mass 330kg-cm2 (including turntable seat) Rotation speed 33・1/3, 45rpm Rotation speed switching Electronic type with short stroke switch Rotation unevenness 0.011% or less (WRMS/FG direct reading method) 0.023% or less (WRMS/JIS) S/N 82dB or more (DIN-B) 65dB or more (JIS) Load fluctuation 0% (stylus pressure within 200g) Starting characteristics: within 1/3 rotation Starting torque 1.6kg-cm Speed detection method Full-circle integral method FG Rotation speed deviation 0.002% or less Drift Time drift: 0.00008%/h Temperature drift: 0.00003%/℃ Brake mechanism: Pure electronic type Model Variable oil braking system Static balance twin pipe exchange method pipe arm Effective length 250mm Overhang 12mm Tracking error +2.7°~-1.3° Needle pressure adjustment Weight 1 rotation 1g Compatible cartridge weight straight: 3g to 11g S-shaped: 6g to 32g (shell included) Height adjustment range +3 -4mm Head shell carbon fiber composite material Attached mechanism: Quartz lock indicator quick stop Silent lift up (electronic) Semiconductors used Crystal: 1 IC: 10 Hall element: 3 LED: 4 Transistor: 11 Diode: 6 Power supply AC100V, 50Hz/60Hz Power consumption 15W External dimensions Width 490x Height 190x Depth 401mm Weight 14.6kg ★The condition of the product is B rank/There is some signs of use such as scratches and dirt, but it is in good condition for normal use.
