I have had reasonable success in a four seater hooking a portable 4 place intercom into the RH audio sockets. Generally the audio wasn't as good but that is with an old pice of kit bought more than 10 yrs ago. I am guessing the newer stuff works a lot better.
I'm pretty sure mine is also a Pilot Avionics also but all four stations are in the one unit
There are 4 place units from the same supplier.
