The VRDS (Vibration-Free Rigid Disc-Clamping System) is used for the turntable mechanism. The disc is clamped on a turntable with the same diameter as the disc, eliminating natural disc vibration and unnecessary system vibration. The disc's crimping surface is gently angled to correct warping and distortion. The pickup is finely adjusted to the same angle as the turntable, ensuring that the pit is always read at the center of the pickup's optical axis and minimizing unnecessary servo current. These features reduce disc read errors and prevent timing errors (jitter) in the clock circuit. The turntable is also made from high-precision die-cast aluminum and rigidly supported by a bridge with a thick reinforcement rib structure. The mechanical base and bridge feature a low thermal expansion coefficient and resistance to temperature changes. They are made of a special polymer material with approximately twice the specific gravity of ABS resin. This material not only offers excellent electrical and mechanical properties but also contributes to high dimensional accuracy. The motor is a brushless Hall motor with high torque, providing rotational stability and high input resistance. For digital transmission, the DSRLL (Digital Servo-Ratio-Locked Loop) circuit used in the Esotheric D-3 is employed. This circuit reduces jitter in the audible band above 3 Hz by 1\/100 (40 dB). The chassis structure has been revised to eliminate vibration and resonance. The top plate has a three-piece structure made of thick steel. The left and right two-piece sections are integrated with L-shaped side panels, making them resistant to twisting and deflection. Thick solid aluminum blocks in the form of bridges directly connect the front and rear panels and are installed at the top and bottom of the unit. In addition to strengthening the chassis, the interior is enclosed in non-magnetic aluminum in a three-box structure, preventing interference between the D\/A, mechanical\/servo, and power supply sections. The bottom chassis is 2 mm thick, and sintered alloy pin-point feet are used as insulators. It uses a ZDII distortion and shaper, and dither averages D\/A conversion errors to achieve an ideal 21-bit conversion step (2,097,152 steps). The VRDS-25x operates in double-differential mode and achieves a significant improvement in SN by operating with a 50 MHz high-bandwidth amplifier. To further improve the ZDII averaging principle, a 1\/16-shift (digital offset) small-signal-oriented DAC is used, eliminating the MSB errors that normally occur near 0 V. By shifting the DAC's 0 V operating point by one-sixteenth of the scale, the zero-crossing distortion that occurs when the input code passes through 0 V is reduced to approximately one-eighth of the conventional level. This greatly improves the r-ty in the signal region (-18 dB or less) where music signals are concentrated. The digital filter also includes a 25-bit 8x oversampling digital filter. It is equipped with a digital servo that adjusts the servo amount for each disc. It controls the optimal servo amounts for focus offset, tracking balance, focus gain, and tracking gain for each disc. The stable and efficient servo current reduces jitter. A digital input is provided for digital signals, and extremely pure D\/A conversion is achieved by passing the signal through a DSRLL circuit. The double-sided PCB pattern design features a wide ground plane, and a central bus bar makes the PCB resistant to external noise while ensuring high transmission efficiency. It also uses carefully selected capacitors, diodes, and transformers, and high-quality components such as brass shavings and gold-plated RCA plugs.\u003c\/p\u003e\n\n\u003cp\u003eType CD Player Number of audio channels Karaoke machines 2 Channel Frequency characteristic RCA : 1 Hz to 20 kHz +\/- 0.3 dB XLR : 20 Hz to 20 kHz +\/- 0.3 dB Signal-to-noise ratio 110 dB or more (EIAJ) Dynamic range 99 dB or More (EIAJ) Total harmonic distortion factor 0.0015%(EIAJ) Wow and flutter Measurement limit value or less (crystal oscillation accuracy) Channel separation 108 dB or more (EIAJ) Analog output RCA:2.2Vrms XLR : 2.2Vrms\/600 termination Digital Output (ON\/OFF Possible) Coaxial (RCA) : 0.5Vp-p\/75 Optical (TOS) : -15 to -21dBm D\/A converter 1\/16 shift 20-bit 4 dac Digital filter 25-bit 8 x oversampling digital filter Analog filter Third order Butterworth filter Pwer 100 VAC, 50Hz\/60Hz Power consumption 18W Outer Diameter Dimension Width 442x Height 145 (When Using Foot : Approx. 153 mm) x Depth 344 mm Weight 16.5kg\u003c\/p\u003e","brand":"TEAC","offers":[{"title":"Default Title","offer_id":59370760372569,"sku":"2622","price":1590.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1066\/5721\/8905\/files\/teac-vrds-25x-1.jpg?v=1789119352","url":"https:\/\/wenwaudio.com\/en\/products\/teac-vrds-25x","provider":"W\u0026WAudio","version":"1.0","type":"link"}
