I want to build a simple DSP with RCA inputs and outputs. I need a minimum of 8 output channels, where I will be connecting 8 speakers individually. After a little bit of searching I came across "freeDSP" that's powered by the ADAU1701 chip. I liked the simplicity of the design and would like to build something similar. Unfortunately, the ADAU1701 supports up to 4 DACs and I can't use it in my build unless there is a way to use 2 ADAU1701 chips in one board. Is this concept feasible? Or Is there maybe a comparable chip with 8 output channels?
