Hi I'm a massive audio noob,
I usually have my speakers plugged into my computer and stopping feedback with a ground loop isolator, however I'm taking my speakers to a party so I needed an aux. I brought an aux to tlr cable which goes into a balance input? I works and sounds fine however in only one of the speakers there is an annoying feedback sound. I begins when I plug the phone in and gets quieter until it stops which is fine. However at random unpredictable moments it makes a very loud feedback sound which comes on and off whenever it likes and i was wondering if there was a (hopefully free) way to fix this.
Thanks v much, Lewis
