I am new to audio equipment and am looking for some help.
Just moved into a new home with ceiling speakers in three rooms. Total of 7 speakers inside and two outside. I bought a receiver and want to drive these speakers but there are four speaker cables coming out of the wall and each cable has four colored wires(red, black, white, green). There are volume controls on the walls of the three rooms. How do I connnect to my receiver? Which colored wires do I connect to the receiver?
