We just moved into a new house...well movers will be here tomorrow. The house has a soundsystem setup in three areas with a wall control. From the looks of it, I believe it was a Niles zr4 system. They have three lines in the basement listed for each area. The previous owner took the receiver, so I need to know what I should get so we can run this system. Not that knowledgeable about receivers so any help would be great. We dont want to spend to much on it though. What should I be looking for in a receiver so we can run this? Thanks!!
