KingRex UC192 - new usb kid on the dac 192/32
I guess things are really moving on the USB front (credits to 6moons):
November 2010 - 32/192 USB/SPIF converter - The new KingRex UC192 [$159] is described as "a very high-quality computer audio transport interface for those wishing to stream high-resolution files to an existing DAC. The UC192 can transfer from PC or Mac at 16/44.1 or up to 32/192 through its S/PDIF & I-squared-S outputs. The UC192 runs isochronous with an adaptive clock generator to auto sync with the host. The master clock generator is a classy 1ppm TCXO unit with proprietary low-jitter drivers for Windows & Mac. Kernel streaming, Direct Sound, ASIO4ALL and WASAPI are all supported and run smoothly. The UC192 is housed in an oval cross-section aluminum case with black hairbrush polish. It measures 88 x 82 x 24mm." The identity of the USB transceiver chip "for now remains top secret". The UC192 ships with Windows and Mac drivers that need to be installed on your computer. An external 7.5V power supply is provided.
Does anyone can explain how isochronous is working? There are two clocks, one generated by PC, one by DAC, and these are trying to sync?
