i have a new house that's prewired for whole house audio and i have some questions. I just bought a Aton 4 Room Audio Package that includes the in ceiling speakers keypad and Aton DLA 4 Router, (waiting on it to be delivered) its going to be connected to zone 2 of a onkyo 508 receiver. house has wall plates hiding cat5 and speaker wires. I know with the keypad i bought only use's the cat5 connection, what is the other 4 wire speaker wire in there for? also for kicks i connected a speaker to one of the in-ceiling speaker locations that location is using two wire...at the house-end its using 4 wire, i connected the four wire at the house-end to my receiver but got no sound, do i need to connect all four wires to the receiver? or do i need the keypad connected with the cat5 first?....i assumed i could just connect the cable and the audio would play with out the keypad..sorry for being long winded but im new to this and would appreciate any help.
