Affordable high-end DAC designed for audiophiles With eight digital (including 2 x IIS/DSD) inputs, RCA stereo output, and decoding capability of PCM 384K, DSD256, the NuPrime DAC-8 is an affordable high-end DAC designed for audiophiles. Main Features: NuPrime SRC IC chip (co-developed with IC vendor) provides DSP processing where Input signals are up-sampled to megahertz before down-converted to the targeted sampling rate with ultra-low jitter and distortion. Extension port for Bluetooth receiver and WiFi audio streamer (optional). Full microprocessor control with memory retention. Supports DSD native playback by ASIO2.1 and DoP method. Asynchronous transfer mode. Volume adjustment in 99 precise 0.5dB increments. Individually adjustable volume on each input for precise level matching of sources. Exclusive driver software for Windows. Standard driver software for Mac. Available in black or silver anodized aluminum finish. Using Bluetooth and WiFi Audio Receivers and Dongles NuPrime defined an USB Type-A port to carry S/PDIF data and 5V power for connecting to external wireless audio receiver using just one standard USB cable. The NuPrime Omnia WR-1, BTR-HD, Stream Mini and Stream Mini DAC wireless receivers have a micro USB port that is compatible this specification. This allow a standard off-the-shelf USB-A to micro USB cable to be used for power for the receiver as well as wireless audio data transfer in S/PDIF format.
