QA730U XMOS USB to Spdif Converter DAC USB Digital Interface

Image Hosting by TupianGuanjia

Description:

QA730U is an asynchronous High Speed USB to digital audio interface that extracts the highest possible audio quality from computer audio sources.

The QA730U streams bit perfect audio data up to 24-bit @ 192kHz, providing a signal clear, and true to its source. The QA730U will output true, 24-bit audio files and supports all these sample rates: 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz.

The QA730U is finely designed to work within your digital system. Your digital system will function together as parts of an instrument. Your QA730U is built to fit effortlessly into your system, becoming a “bridge” between your computer and your DAC.

Great care was taken in the design of the QA730U to isolate the noisy computer/USB environment from the digital audio output. The USB receiver and processing are powered by the computer, while the output line drivers are powered by a separate isolated linear power supply.

The QA730U's USB is designed to work with both Apple Macintosh and Windows PC computers. Microsoft Windows PC’s require the included Windows driver which works with Windows XP, Vista and 7 and windows 8 and Windows 10.

24bit/192KHz wav and DSD Support

QA730U supports Studio Master wav files in 24bit/192KHz and DSD64/1bit/Stereo.  DSD files can be streamed out of the digital output in DoP format.
