I would like to use two TAS5754's in PBTL, one for Left and one for Right. I would also like to use a TAS5760 in PBTL for the subwoofer. However, I don't see a way to combine the Left & Right audio streams after the Hybrid Flow (low pass sub filter) and put that combined, filtered signal out on DSOUT/GPIOx to feed to the TAS5760. Is there a way to do this? Or do I have to resort to using three TAS5754's?
