Oh yeah that’s correct, completely forgot about that lol. My bad there. That would also work at reducing the level of the quicksilver you would just need some adapters for that (3.5mm to rca)
Out of curiosity if you feed the rnhp with rca is it somewhat similar volume to what the quicksilver would be? Might just be solvable by an rca splitter if that’s the case, and would end up with the least amount of quality loss imo
