Default Audio Auto Switch

Hello everyone.
I need to find a way to switch the sound from a tuner and a pbx. For sound I am using a Yamaha Amp and speakers.
I have a tuner and a PBX (Phone Box Switch). I want to use the tuner for music, and the pbx for public address. Whenever any one picks up a phone hooked up to the pbx, they can dial 33 and start talking. I need to find a device that will automatically turn off the signal comming from the tuner, then switch on the signal coming from the pbx (There is no signal comming out off the PBX when the PA is not being used). After the Public Anouncement is done, switch the signal from the pbx off and turn on the signal from the tuner. Any suggestions will be greatly appreciated.
