Question about TEAC TN-180BT-A3

The record player can be connected to a Sonos Era 100 via Bluetooth. However, it is not possible to connect it to multiple Sonos Era 100 devices at the same time, as Bluetooth normally supports a 1:1 connection. If you want to use multiple Sonos Era 100 devices, a wired connection via RCA cable and a suitable adapter might be a better option.
