[borischelski]

Dear Sirs

I am not a HIFI expert here so please excuse my ignorance here.

I am using an Amazonbasics Bluetooth receiver to play music from iPod touch through the Marantz integrated amplifier PM4200 on my HIFI.

However I experiencing significant sound interference through the speakers which I can only describe as similar to the sound produced through intermittent "blowing into a hand held microphone". Initially I thought I had a fault with my speakers but in practice this interference only happens when the Amp is set to AUX setting.The interference happens not only whilst music is playing but also in between tracks or when no music is playing at all.It also ha

I plug the red and black plugin attachments directly into the red and WHITE plug holes headed "Aux"at the rear of the amp.

any advice to fix this problem would be greatly appreciated.

Disconnect the bluetooth receiver. If the noise goes it's that causing it.
