I took the liberty of taking a few pictures of the area on the Empeg motherboard that I believe to contain the "I2S" pads with my aging digital camera. Attached is the best one. I believe, based on the leads from the Philips DSP that the pads are the ones in the picture named "IIS", but I'm not positive. Can anyone verify this?

What are the other pads for? It looks like there are pads for another IC. What are they for? What are the "IIS Power" pads for? And also the "ProI" pads?

Thanks,

I just want to say that I hope someone figures this out. I have an all digital hifi system in my home (Meridian) which has nothing but the finest DAC's at every speaker cone. I absolutely know that my Empeg will sound better when plugged into this system if it could feed the Meridian with direct Digital output.

Mmmmm...all Meridian.

I assume they're the digital loudspeakers? My CEO has those.

After a little more research, it seems that indeed "IIS" and "I2S" are different names for the same thing. So at least I have found the outputs of the empeg. Now the questions is how to go from IIS to the inputs on the CS8405 chip, which needs serial data and word rate clock inputs. What circuitry is needed to interface the CS8405 with these IIS outputs?

According to Hugo,

there is a 2mm header (row of holes) on the board that has the following: ground, 3.3v, I2C clock, i2C left/right, i2C data front/rear.

Perhaps this header is the set of pads labeled IIS?
