Hi everyone, I have a mini dsp that I want to use to bi-amp some speakers. I have some powersoft digimod 1000 and 500 that can be used both unbalanced and balanced, but the output level of the Mini dsp with an RCA connector is too low in terms of volume to be able to drive the amplifier. I tried some adau modules from sure and the result is the same. Where can I buy a PCB that acts as a preamplifier between the DSP and the amplifier? AliExpress? How should I search? Do you have any links? Thanks
