I have connected them together with the s5 cable as Dig in and coms in, then the one speaker to the 511 with the comms and then the other (dig out) to the g68 as rears. I not sure if on the connection if it should be connected to dig in 1or2, or if on the config withing the speaker it should say slave 1 or 2. When I turn the system on they turn on with the correct source and volume level, but no sound.
