The SOtM dAC-200-HD is a 24/192 audiophile digital to analog converter. The DAC is equipped with multiple high quality inputs to accommodate using a variety of digital sources. You can connect devices with AES/EBU, coaxial RCA, optical Toslink and your computer with USB audio class 2.0 input. The DAC is compatible Windows OS, Apple OS-X, Linux. The DAC uses an asynchronous transfer mode via USB which is not affected by the computers low quality clock. The DAC chip is a voltage output design rather than the typical current output designs. This makes the output circuit simple and minimizes sound coloration. The output circuit consists of passive L-C filters for low-noise characteristics. In order to supply stable power the DAC incorporates noise filters, dual power transformers, and ULNR (ultra low noise regulators). Power supply noise filters are used to block high-frequency noise coming from the power source. Individual power transformers with high insulating properties for the analogue circuit and digital circuits were used to maximize the DAC´s performance.
In addition the DAC uses ULJC (ultra low jitter clocks) in the digital circuitry.
