I want to understand the technical characteristics of the USB audio output on the Streamer DMP-A8

I would like the engineers at Eversolo to inform whether the USB Audio output located at the back of the DMP-A8 outputs a synchronized audio signal or an unsynchronized audio signal acting as a transporter?
VINHSTUDIO.

 

This depends on the receiving device too; if such device is a UAC1.0 it would relay on the A8 (the source in this case) dictating the clock; while if UAC2.0 it would dictate the clock itself, and request the A8 to send data asynchronously.
The A8's USB is UAC2.0 compliant, hence I'd say it will only depend on the attached device.
I am no Eversolo engineer, but my knowledge about UAC1.0 / 2.0 suggests me the above.
