Searching the manuals, I cannot find the answers to USB audio in and output.
I know that 24‐bit, 48kHz optical S/P DIF, will provide an excellent signal to and from Kronos/Audio Interface/Computer.
That being said, can someone shed some light on the USB audio (B) connection and how it measures up to spdif?

When using S/PDIF, you make the appropriate selection in Kronos.
Why then, is there no settings when using USB in Kronos? This is a digital connection also, right?

Sorry for the lack of knowledge here, Embarassed

I have used analog connections forever and will now be switching over to USB or S/PDIF,
just trying to understand exactly what it is and what the differences are, .. thanks.

The USB would definitely be the same 48 kHz and probably 24 bit too.

USB 3 would have been a nice touch though.

I'm not sure exactly what you're asking. There are settings in the manual that refer to the USB I/O. For example, in the Operation Guide page 195, the Audio Inputs section shows that you can select USB as an input to the effects or to sampling, same as S/PDIF. As far as USB output, I think the USB just outputs the same thing as the main analog output except that it's a digital representation of it. So if there's a lack of output selection for USB maybe that's why (I haven't searched specifically for that.)

The SPDIF connections look like lightpipe/optical (from what I can see).

The USB (a) & (b) issue is this -

USB (a) is the long flat connector/socket arrangement - for connecting thumb drives/hard drives.

USB (b) is the "squarer" connection - usually found on interfaces (in this case, Kronos is being used as an interface)

So how they all measure up? They're all outputting the same thing really, although the optical will be "audio", adn can be connected directly into a digital mixer, for example.
The USB stream/connection will be data, and has to be connected to an IT-related device.

Hope this helps a bit Cool
