I am not aware of any pre-existing options for deriving digital audio output from the Empeg. That is why I am pursuing building a small board to connect to the IIS pads on the board. I still need to know what each of the IIS pads does on Empeg board. Could someone tell me what signal is present on each IIS pad (from top to bottom on the picture in my previos post) or do I need to investigate this with an o'scope? I must admit that at the moment all this seems a little overwhelming. I am not quite up to speed in electronics design and esp. digital circuits. My plan is to take the applicable circuitry presented in the CS8405 eval. board and build that.

The CS8405 has a 3 wire serial audio interface. What I need to know more than anything, is how to get the ILRCK (serial audio left/right clock), ISCLK (serial audio bit clock) and SDIN (serial audio data) signals into these pins on the CS8405 (pins 12-14) from the IIS pads. If someone could just tell me that, I would be on my way.

Thanks,

Stu
