{"product_id":"accuphase-dp-70v","title":"Accuphase DP-70V","description":"\u003cp\u003eThe DP-70V is equipped with a digital control center function and can demodulate digital signals from multiple DAT and BS tuners via digital input \/ output jacks. In order to realize the function as a digital control center, three sampling frequencies are built in, and the source frequency is automatically selected.  A 20-bit discrete D\/A converter is used for the D\/A converter. The DP-70V consists of a current addition type with an advantage in linearity. It is composed of a discrete method with carefully selected elements in order to realize the performance of the 20-bit theoretical limit value. The DP-70V consists of a current switch element and an ultra-precision resistor. Each unit is strictly adjusted for complete operation. This realizes ideal linearity in the whole output level range from minute level to large level, and eliminates 0 cross distortion and distortion at small output.  The digital filter uses an independent 20-bit 8 x oversampling digital filter on the left and right sides. The DP-70V filter uses advanced digital calculation techniques to successfully suppress the frequency range between 24.1 and 328.7 kHz to an excellent value of -110dB, while limiting the passband ripple, which causes sound quality degradation, to within +\/- 0.00005 dB.  The audio low-pass filter uses a GIC third order Butterworth active filter with carefully selected elements. This output is directly output through a buffer amplifier with a gain of 0 dB.\u003c\/p\u003e\n\n\u003cp\u003eError correction method : CIRC Number of channels : 2 channels Rotation speed : 500 - 200 rpm (CLV) Performance speed : constant 1.2 - 1.4m\/s Reading system Non-contact optical reading (using semiconductor laser) Laser GaAlAs (double hetero diode) Digital Output Format Level (equivalent to EIA) Formatting : Digital Audio Interface Optical : Optical power : -21 to -15dBm (EIAJ) Emission wavelength : 660 nm Coaxial : 0.5Vp-p\/75 O Digital Processor Division Formatting EIA standard format Quantization number 16-bit straight line Sampling frequency (Timing Accuracy : Level II) 32.0 kHz +\/- 0.1% 44.1 kHz +\/- 0.1% 48.0 kHz +\/- 0.1% Frequency characteristic 4.0 Hz to 20 kHz +\/- 0.3 dB D\/A converter Discrete 20-bit Digital filter 20-bit 8 x oversampling Noise shaper function Digital de-emphasis function Deviation +\/- 0.001 dB Total harmonic distortion factor + noise 0.0016%(1kHz) 0.002% (20 Hz to 20 kHz) S\/N 119dB Dynamic range 98dB Channel separation 109dB Rated Output \/ Impedance Balanced : 2.5V\/50 O (25 O \/ 25 O), balanced XLR type Unbalanced : 2.5V\/50 ohm, RCA phono jack Output level control 0 \/ -40dB, 1 dB step (digital type) Digital Input Format Level (equivalent to EIA) Formatting : Digital Audio Interface Optical : Received power : -15dBm to -27dBm Coaxial : 0.5Vp-p\/75 O Power consumption 23W External dimensions Width 475x Height 135x Depth 389 mm Weight 24.3kg\u003c\/p\u003e","brand":"Accuphase","offers":[{"title":"Default Title","offer_id":59370598891865,"sku":"1672","price":2390.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1066\/5721\/8905\/files\/accuphase-dp-70v-1.jpg?v=1789118250","url":"https:\/\/wenwaudio.com\/products\/accuphase-dp-70v","provider":"W\u0026WAudio","version":"1.0","type":"link"}
