A:AnswerI have observed a warping sound on 1 out of 40 vinyl records. I attribute it to the condition of the album and not the turntable. If you experience this issue playing every record and the condition of the albums are not suspect, then I'd pursue investigating potential defects in the turntable.
A:AnswerThere should be "input" buttons on the remote or on the receiver itself. Those should be used. Also check your connections to make sure turntable is connected to receiver correctly. Good luck.
A:AnswerIt works with any bluetooth speaker or headset. I've connected a Bluetooth audio receiver to my head unit to get this player to output on the home theatre.
