Hi all, Long time reader, first time poster. So I recently moved into a new house. One of the things we noticed when we were viewing was that there were ceiling speakers in almost every room of the house. There are also a plate consisting of 4 gold ports (two with red band, two with a black band) in three separate rooms. In each location there is also at least one ethernet port and a telephone port. When I asked the owners what this was I was told that it was a sound system throughout the house, where you could pick what room you wanted the music to play, but that I would have to ask the lady's husband more about it. So I did, but he couldn't tell me what I needed in order to control this, as he had never used it since getting it installed. Anyway, I was hoping if someone could help steer me in the correct direction as to what I would need in order to use this please? I have included a couple of photos and more info on the locations. Dining room/kitchen 4 inputs, 2 speakers Spare room 4 inputs, 2 speakers Bathroom 2 speakers (the previous owner was able to tell me that the little wall switch (pictured) in the spare room controlled the speakers in this bedroom (pair A) and the bathroom (pair B)) Master bedroom 4 inputs, looks like there used to be speakers mounted on the wall The living room is more confusing. There are no inputs in this room, but there are two speakers in the ceiling, two at the TV, and two outside. There are a lot of badly labelled white cables under the TV saying things like "external left/right" (obviously the outside speakers), "internal left/right" and then a lot of unlabelled grey cables. I don't know how these would fit into the overall "linked" system. Apologies for all of the information, I hope someone can shed some light on what type of system I would need to control this. I do worry that this isn't a fully integrated system, that I will need one control system for each set of ports, and that those ports are only connected to up to four speakers. Thanks for reading!
