I've seen some posts that explain a partial solution, but this seems somewhat unique. I just bought a house that has 4 zone speakers pre wired. 3 of the zones are normal stereo pairs, but for some reason they wired one zone with a speaker facing inside the house and the other speaker in the pair out on the balcony. Audio is sent to that pair as normal L/R, but each has it's own volume controller and unless you're standing in the doorway you don't hear both channels. I want to take the stereo signal output from a 4 zone selector switch, sum it to dual mono and send that dual mono signal to each speaker in the 4th zone. From research I know I need to build some sort of summing device with resistors, and that's where I need some help. Here's a diagram of what I have going on:
Yes, I know I could use a standalone amp for just that zone and send mono audio, but I'm stubborn and don't have an extra amp lying around 😉

I'm not sure what's meant by a 100 V network. Each set of speakers is equipped with a volume control/transformer. That 4th set has a controller assigned to each individual speaker with one pair of wire going to each controller (one receiving L and one R).
Currently I'm powering with a 200w power amp from an old PA system. I'll be buying a more compact amp in the future that can be easily tucked into a small cabinet (something like a small Fosi amp).

Ohmytodd flies the USA flag icon, so will not be 100V stuff, 25V or maybe 70V.
-OR- it could all be done at speaker level. Hard on the amplifier but we don't know who set this up.

Thanks for the clarification. The previous owner set up the system about 10 years ago during a home remodel. Based on the fact that he ran a single side to each of those upstairs speakers tells me he didn't fully grasp what he was doing, but he tended to operate on tight budgets with good aesthetic results.
- One stereo speaker pair is in ceiling in living room
- One pair is on the front porch and both are infinity brand
- One pair is on the back deck, the green bose outdoor speakers
- The final pair upstairs in infinity as well, one inside and one outside
