ADAU1701 & Expansion 2 in 3 Out Static

Greetings,

I just picked up a ADAU1701 Audio Digital Signal Processor Kernel Board and Interface Extension Kit- to make 3-Way speakers. I get very loud static- I have tried 4 different amplifiers- even with the amplifiers off static is still there.

These are amazing boards but unusable due to static. Static can be heard from all 3 outputs.
