assume this could be used to work with a sonos connect, which will give more flexibility?
Hello,
The BeoLab 3500 requires the trigger voltage from either a PlayMaker or Bang & Olufsen audio system / video system to activate the amplifiers. There is no 'LIne' mode like you may find on other BeoLab speakers.
Because of this, the BeoLab 3500 would have to be connected to a Bang & Olufsen product via PowerLink.
