Reply To: BeoLab 3500: how to fix ML input selection? May 3, 2022 at 1:46 pm #4665 francoisvlBRONZE Member I use a beolink 1611 converter with all my stand alone BL3500’s. Works perfectly. Only have to press one button to start listening and you can alter the bass, treble etc and the preset volume. You can’t do anything like when using just a cable.
