Why do my speakers hum when connected to my turntable?
-Make sure your speakers are not sitting on the same surface as your turntable as this can cause distortion in the audio.
-Check your tone arm to assure it is calibrated and balanced.
-If your turntable has a grounding cable, make sure it's attached to a nearby metallic source like an external phono preamp/stereo receiver/etc.
-If your turntable has a built-in bluetooth transmitter, make sure it is not both hardwired and bluetooth-connected to your Audioengine speaker system as this will cause a feedback loop. You can manually disconnect any bluetooth-connected source from your Audioengine speakers by holding down the bluetooth LED button for a few seconds till it starts blinking.
