Analog input for the DAC+ DSP


I'm trying to build a standalone stereo DSP effects processor and I have two questions about the DAC+ DSP board:

  1. What's the best way to add a stereo analog input to it? Can I combine it with the DAC+ADC PRO board using the I2S interface? Can I exclude the Toslink input on the DAC+ DSP and just use the I2S input?
  2. Can the DAC+ DSP work in standalone mode, without Raspberry PI, after it's been programmed?

Many thanks!
