The Brennan VB1 is a totally unique device that lets you play vinyl and other music sources wirelessly to Sonos speakers and Brennan music players.
Simply connect your music source to the phono connectors on the back of the Brennan VB1 then press the button on the top to start and stop transmission.
(When using a turntable it must either have a built-in preamplifier or you will need to add a Phono preamp between the turntable and VB1.)
The Brennan app is used to connect the Brennan VB1 to same Wifi network as the Sonos speakers or Brennan player.
You can use the app to select which speaker or Brennan you want to send the music to. The app also lets you control settings like gain and sample rate.
