[(350853)input 220V]![](https://ae01.alicdn.com/kf/S16d1cf1cc664490582ee36305a64c7b2t/CS8416-CS4398-USB-Audio-DAC-decoder-OPA627AU-OP-AMP-PCM-HDCD-Digital-decoder.jpg_640x640.jpg)
Three advantages:
First, this DAC is a hot seller on ebay.
Second, feedback from useful friends. If the operational amplifier is changed, the value of this DAC will be multiplied.
Three, foreign websites take the board for LT1361 after the operation, sell $875, you can directly copy the following connection to see! http://www.decware.com/newsite/ZDAC1.html
Local configuration:
The 1,220V power supply is equipped with a special filtering circuit to minimize the dry winding caused by the power supply.
2, R-type transformer power supply, the board power supply is divided into 5 groups, to each circuit unit separate power supply (using high-grade HIFI machine 317.337).
3,USB uses the enthusiast most used PCM2902E, receive chip CS8416; Decode (DA) as CS4398.
4. Two pairs of the operation amplifier should be equipped with an OPA627AU
Free a thick power cord, a USB cable with magnetic ring,
5, no upturn board function
6, the resistance capacitance, for the United States "DALE" brand (a resistor needs 0.5 yuan, not other brands of what color ring resistance) capacitor of Japan "ELNA" or black gold steel.
7. Specially made 10PPM crystal oscillator, not ordinary goods
8, output RCA and coaxial RCA, using Taiwan gold-plated high-grade RCA(not 1-2 yuan common goods),PCB and RCA with silver plated wire connection.
We do not accept the application for return of bad sound quality (for those who think the sound quality is different from their favorite, they can ask the store's main schematic diagram for polishing by themselves, which is the fun of DIY), because there is no uniform standard for sound quality, and everyone has different hearing, so it is difficult to unify, and there is no need to ask for comparison with the DAC.
Board size: Long 130mm wide X 175mmX high 45mm)
Finished machine: Length 290mm wide X 200mmX height 70mm
Weight: 4 kg
PCB professional custom, copper skin is thickened (2 oz, general PCB is 1 oz), the material is 2mm.
Digital analog separate rectifier power supply. The DA and the digital connector power supply are also separated for reciting power supply (LM317,LM337), which are divided into 5 power groups to ensure that each part of the power supply is independent.
The optical fiber head is the original Toshiba RX179 imported from Japan
PCM; HDCD; Digital decoding,
1. Optical fiber (supports up to 96KHz/24BIT input)
2, coaxial (support up to 192KHz/24BIT input)
3, USB(support maximum 48KHz/16BIT input)
Note: If it is DTS, AC3 disc, DVD, HD or computer digital audio output must be set to PCM; If it is DTS,AC3 signal is 5.1 source signal, directly input DAC is not able to solve the code, need DVD decoded and re-encoded into PCM stereo digital signal into DAC, if you put APE or CD format, you can set as source output!
