That Oneremote preamp has given me an idea but I’d be surprised if it works. The Beosound 4 has one disappointing feature – it only has standard RCA aux input, so no Beolink/Audio Aux Link.
I do have a 1614 converter going spare though. Do you think if connected my BG3000 to the Oneremote device, then to the 1614 converter via A.Aux link cable, then to the BS4 via Masterlink, then I would be able to control my BG3000 via remote control?
