Aluminum shell, exclusive thickening of the panel the 8MM before the panel and the 3MM,all CNC precison machining

Description:

D20 uses in a wide range of devices ,such as computers, digital turntables, DVD players, digital playback that are with the USB interface, the coaxial output or optical output .

The panel font using laser engraving technology,never fade

Power special handling instructions and UNLOCK instructions,conspicuous without glare

The rear panel is the CNC precision machining,perfect details,non-processing rough stamping process comparable

Coaxial input Block and analog output with high quality 24K gold-plated terminals, good contact, durable

PCB with Immersion Gold technology manufacturing, components on the PCB by automatic precision SMT processing

The Precision power supply circuit

D20 uses U.S. National's LM1875, external input power is converted into the the HIFI universal dual power.The power supply circuit with a capacitance of of Japan nichicon Gold and Panasonic HF FC Series capacitor ripple and noise control excellent.

Fever LPF filter circuit

Output signa of D20 DAC chip PCM1793 output signal contains the high-frequency waves, the active low-pass circuit LPF.LPF circuit uses the U.S. Texas Instruments HIFI op amp OPA2134, with the KOA resistors, capacitors Siemens, the ERO capacitor, capacitance to form nichicon Gold.

High-accuracy USB-to-coaxial

      USB access to the signal from the Texas Instruments PCM2704 converted to SPDIF digital signal processing by the decoding circuit. D20 extension products customized for the PCM2704 with high precision crystal oscillator, to improve the stability and accuracy of this section.Although the PCM2704 can only support up to 48kHz/16bit, but the most common digital audio source is still 44.1kHz or 48kHz, 16bit, the PCM2704 already sufficient

DIR-DAC circuit

      This is the core of the D20 Part 2. Using a Texas Instruments the DIR9001 and PCM1793. The DIR9001 will input SPDIF signal conversion accepted by IIS signal as DAC, it has a very low jetter. PCM1793 converts to IIS into the output signal.
