Having problems with bringing a signal into the Kronos through S/PDIF.

It seems to come in really loud and has a bit of digital distortion with it.

I've tried:
- lowering the input volume. Distortion still there
- input from a different source (different computer). Distortion still there.
- changing the word clock source on the Kronos. Kronos gives me a word clock error message.
- hooking up computers to different hardware--to each other and also to an amplifier. Distortion not there, so it's something specific with the Kronos.

Has anyone had or dealt with this issue?

I'm going to take a shot in the dark here. The Kronos operates at 48k only and not 44.1k. It has an internal clock and the ability to receive word clock externally. If you go the external route your word clock source has to transmit a 48k signal. Your source you are trying to spdif into the Kronos has to be set to 48k as well, or you are going to have all kinds of weird digital snap, crackle, pops and/or it just won't work, or distort badly. I use an Apogee Big Ben as my clock source piped into the spdif in-port of the Kronos. All my gear, audio interface and computer DAW are running at 48K. No problems as all my gear is receiving a rock solid 48k clock rate from the Big Ben.

The Kronos word clock error message comes when the external clock rate doesn't match 48k or the Kronos is not rceiveng external clock.

Try setting your source to 48k and the Kronos to internal clock and see what happens. Alternatively, set your source to receive external clock 48k, leave the Kronos set to internal and see if that works. You can also try to set the Kronos word clock to external, and set your source device to 48k and transmit it to the Kronos through spdif. All the above assumes you can set your source device to transmit/receive, the one you are trying to spdif into the Kronos, to the 48k clock rate.

I probably over analyzed and thus further confused the situation. Bottom line your clock rate from your source has to match that of the Kronos, which is 48k.

Well, after scouring the Internet, it appears that the problem is with Soundblaster cards (XFi and Audigy)

They can receive word clock properly through S/PDIF in, but they have send issues and they cannot be slaved. Too bad for me. Thanks to all who replied.
