Stream Audio via USB from Your Windows or Mac PC at Better-Than-CD Quality.

Streaming Digital Audio via USB Better-Than-CD Quality Playback
The UD-H01 digitally transfers audio source materials stored on a computer at up to 24bit/192kHz for streaming playback. The UD-H01 supports USB asynchronous mode, using the precise internal clock to control timing and eliminating jitter issues. This allows optimal playback of high-resolution digital audio files from playlists/libraries on your iTunes, Windows Media Player or similar playback programs.

192kHz Up-Conversion to Reduce Jitter Even Further
All digital input signals are converted to 192kHz via non-integral up-sampling, dramatically reducing jitter and allowing consistent D/A conversion based on the high-precision internal clock. ASRC conversion is used to produce a natural, 192kHz high-sampling rate digital audio signal.

Dual-Monaural Configuration with Independent Left/Right D/A Converters
The UD-H01 incorporates two BurrBrown PCM1795 D/A converters, one for each channel. The dual-monaural configuration eliminates interference between the channels for maximum performance from the D/A converters. A shunt-regulator circuit supplies the current to the D/A converters in order to eliminate ground noise generated by fluctuations in the supply voltage.

Refined Analog Circuit Design for a Simple Signal Path
The analog circuit design features a left/right symmetrical configuration to ensure signal paths of identical length for the left and right channels. The UD-H01 incorporates a MUSES 8920 FET input operational amplifier with outstanding I-V conversion performance for high-quality analog output, including headphones output.

High-Performance Power Supply to Guarantee the Maximum Performance from all Components and Circuits
The UD-H01 uses a high-capacity toroidal-core power supply transformer capable of providing a stable current with high efficiency. This minimizes flux leakage and eliminates noise generated by electromagnetic induction.

Ideal as a High-Quality Headphone Amplifier as well
The same high-quality operational amplifier used for line output is used for headphone amplifier output. A dedicated high-quality aluminum knob controls headphone volumes. This allows users to enjoy a high-sampling-rated digital audio in spaces with neighbors close by, or other situations where speaker playback might disturb others.

Input/Output Terminals for Incorporation into Full-Scale Hi-Fi Systems
The UD-H01 features coaxial and optical S/P DIF digital audio inputs and a USB port to allow use as a high-quality D/A converter. Output terminals include gold-plated RCA connectors, line-level output and XLR balanced output terminals for connection to a full-fledged high-end operation amplifier. The unit features a professional-style 3-pin power socket.
