Hi,
Can the HifiBerry DAC+DSP do 4 way crossover? It has a dedicated DSP (the RPi below the board has no role in audio, which is good actually).
Below are the board details. The board has 2 RCA outputs and looks like we can use eDAC connector to add another external stereo DAC to make 4 outputs for lets say a 4 way DSP enabled speaker, one channel of course, lets say the left.
Below I propose that using another such RPi/Hifiberry DAC+DSP set we can route the same SPDIF to to the second board and get 4 way out same way. So now we have 4 way stereo DSP system. No latency issues at all.
Can somebody confirm that
a) Is this possible?
b) then which board to use as a external DAC?
c) and how to make sure RCA are enabled as well as eDAC is enabled simultaneously in both the HIFIBerry DAC+DSP boards? ie how to make it a 4 way system?
Warm Regards,

As far as I can tell (I do not own this HAT) there are only 2 audio channels from the on-board SPDIF and analog outputs (possibly these are just duplicates of each other). The board has a header with I2S signals, (the connector labeled "5") probably from other DAC channels on the HAT, but these are not all that useful without some serious work.
