Spdif coax to usb?
 
Is it possible to feed a usb input on a dac with a spdif coax output?
I have an unused usb input on my dac and a cd player with spdif coax out.
I have used up the other coax inputs on the dac.
Can I create a simple patch cord? If so which of the usb connections are the signal carriers?
Thanks.

Short answer: no.
I made a patch cord and tried it. Terminals 2 and 3 are the data terminals on the B style USB connector.
2 is data -
3 is data +

USB is a completely different data format to SPDIF. Also, the USB input on your DAC is to connect to a computer - the DAC appears as a sound card to the computer.

Cool try tho, thanks for that. As Jaycee says, completely different signal, even tho digital.
At least you tried, and learned the direct way.

Thanks for the positive responses.
I am a pro musician with a hi-fi jones and am always trying stuff. I end up with really sweet sounding systems because I decide by ear. Guests are often fascinated when they hear my rigs because there is that magic in the air... that sound they usually don't hear in home systems.
Thanks again,
