The Bang & Olufsen Beolab 3500 is a beautiful speaker, but many people wonder how to connect multiple Beolab 3500s simultaneously and stream music to them.
With the right adapters and a Masterlink setup, this is very simple. In this guide, we explain step-by-step what you need and how to connect it.
Required items:
To connect multiple Beolab 3500 speakers together, you need:
Beolink 1611 converter.
Masterlink distributor (6 or 10 ports, depending on the number you wish to connect)
RJ45 Masterlink adapters (one per connection)
CAT7 network cables
DIN5 to mini-jack cable (MP3 cable)
WiiM Mini streamer → available immediately at PowmasCables.com
Beo4 remote control.
Connection Step-by-Step Guide
Connect the WiiM Mini to the AUX input of the Beolink 1611 using a DIN5 to mini-jack cable.
Connect the Beolink 1611 to the Masterlink distributor via an RJ45 Masterlink adapter and a CAT7 cable.
Connect each Beolab 3500 (or Beolab 2000) to the distributor using its own RJ45 Masterlink adapter + CAT7 cable.
Activate the speakers using the Beo4 remote control (e.g., TV button).
Now you can stream the same music in multiple rooms simultaneously.
How do you stream music?
Stream from your phone via the WiiM Mini (Spotify, Tidal, Apple Music, internet radio, etc.).
The Beolink 1611 distributes the signal to the connected Beolabs.
Each Beolab 3500 plays the same signal (multiroom audio).
