I would hedge your bets on the summing resistors.SpikedCola:
Points noted. Also, in terms of connecting the boards together, should the summing resistors be on the master board or on the slave boards? I was hoping to use a larger conductor (~14ga) to hook the outputs of the slaves to the master to make up for having separate boards, but Im not sure if it will work. Again, this is all a learning experience for me, so thanks for taking the time to help! (all of you)
Use placeholders on each power amp to include the
local resistor. A better method is sum the amps off
the PCB (the speaker connector area would be good
location). With placeholders you can try it out with
the resistors on the PCBs later.
PCB errors are not forgiving. Better to have all theSpikedCola:
I havent actually picked components yet, I just guessed at the components I would be using, assuming I can change the package and board layout later on if I come across something. However, I think I may need to rethink that (and the other 0.1uF caps) as the original design calls for Wima 63v caps
parts on the BOM in the PCB editor first. This may
require downloading and reading many datasheets,
and creating accurate PCB layout footprints.
Probably the least fun part of any project for me!
