I have a passive speaker that I would like to upgrade with a hifiberry amp so I can stream spotify etc.
However I would like to be able to plug RCA analog into the rpi so I can plugin my pioneer ddj controller.
I'm unsure what hardware to get to achieve this, I believe the following
- rpi 4b (or any one that fits the DAC+ ADC board)
- DAC+ ADC
- RCA to 3,5mm jack (to input into DAC+ ADC)
Is this correct? Or can this be achieved with just an Amp2?
Also how would I switch from lets say spotify to analog input?
