I have recently moved into a new apartment. The seller left behind what must have been a quite costly audio system installed ca. 2010. The heart of it is a Niles GXR2 receiver. It is connected to speakers installed in the walls or ceilings of multiple rooms. There is a handheld Niles controller on a charging base that enables you to select the rooms that will play and control volume.
The system as set up has just three inputs labeled on the controller: ipod, xm, and fm. There’s no ipod there, nor do I have (or want) an xm subscription. The fm does play, but the reception is very poor. I brought from my last residence a Sonos Connect unit that can stream music and radio broadcasts from the internet. I have gone through the setup procedure and the Connect unit appears to be receiving our home wifi. I now would like to connect it to the Niles receiver. The Sonos Connect unit has left and right analog outputs. It will be the only music source.
Thoughts invited on how to connect the Sonos Connect unit.
