Help Witt's End Jays CDT3 HDMI i2s To Terminator Dac

I just received a tubulus concentus i2s cable and installed

In the system set to HDMI i2s and it sounds like the music is stuck between

two radio stations lots of static. The Dac did not com with a manual.

Looking on line I was unable to find the early version. From what I

understand it has to be set up through a series of button pushing.

Tried different ways of doing so with no luck.

Anybody have a simple way to configure this setup?

I have to say  the BNC made life easy.

Thanks so much.
