I have several sony 6-1 700w Recovers in different rooms around the house at my last party the dj had an fm transmitter that sent the audio for his board to any fm recover in the house I got one and want to be able to send audio for the main system to the rest but there is not a audio out for every selection i.e. DVD cd fm ect. and there is not an audio our that covers them all so if I am using the cd player I hook up to audio out on the sony recover for cd but if I switch to TV or some other component I have to move the jacks to that audio and not all of them have audio is there a pre amp or something I can use to be able to send audio to all my systems regardless of witch component I am using or do I need a better receiver or amp on the mail system
