Hi
im trying to connect my unmarked party decks to my Sonos amp with 2 rca leads, I have turned the amp to line in using the amp but it can’t detect the unit, I’ve tried starting every thing up , then plugging in the rca leads but still no sound and nothing detected, do I need a pre amp
many thanks
Thanks for reply, all sorted I forgot to select the input on the app, 
The RCA cables should be connected from the Master Output on the Numark to the RCA inputs on the Amp. To play the line-in audio, go to the Browse tab in the Sonos app and select the Line-In option. You can also set an Autoplay Room under the Line-In settings for the Amp.
