10. How to pair Air Link to two Bluetooth devices at the same time?

The Air Link supports Bluetooth multi-point connection, allowing pairing with two receiving devices simultaneously.

After the Air Link is connected to Device A, you can press and hold the button to enter pairing mode again, or use the FiiO Control app to force the Air Link back into pairing status. Alternatively, you can turn off Device A and wait for the Air Link to automatically re-enter pairing mode.

If you wish to connect to Device B while both Device A and B remain powered on, simply disconnect and then reconnect the Air Link. It will automatically reconnect to both Device A and B upon restarting.

Both Bluetooth receiving devices support the LDAC format, but when using Air Link for dual output, why does it show the SBC format?

This is normal. Due to the high bitrate of LDAC/aptX Adaptive, the limited Bluetooth bandwidth cannot support dual simultaneous streams.
