dAC-200HD

Clear

dAC-200 HD is the 32bit D/A converter for the middle high class audiophiles, it consists of AES/EBU, coaxial inputs to use with any digital source devices as a CD, DVD player or TV and has USB audio class 2.0 interface to use with PC.
To enhance and rich your sound quality, the sCLK-2224 can be installed as an optional and the 32bit SRC(Sample Rate Converter) is applied. Please check the information about sCLK-2224 here, sCLK-2224 is the most important part to transform sound to be much more dynamic and natural with the wide bandwidth. The SRC is good to use with not only DVD, TV which are having a possibility to make sound improvement a lot but also the high performance audio source since the SRC outputs the same 32bit as DAC chip, so this procedure changes sound to be wider and dynamic range.
The DAC chip is the voltage output type which is not the same one as the current output type, this type of output make reduces coloring sound and the ultra low noise analog output circuit which is consists of Passive L-C filter and the balance circuit support up to 100KHz bandwidth which is compatible with 192KHz completely.
For the purest power, the power noise filter, Dual power transformer and ULNR(Ultra Low Noise Regulator) are applied. The power noise filter blocks high frequency noise from the power and the power transformer maximizes the sound quality by applied separately for analog and digital circuit.
Also the balance of ULJC, the best specified electrolytic condenser for audio and the polymer condenser reduces noise entirely and helps realizing the high resolution sound.
