What are the inputs on the Uber FX2 speakers?

Each Uber FX2 has two Combo XLR and TRS jacks that support both balanced and unbalanced audio for channels 1 and 2.  There are also two dedicated auxiliary channels, receiving audio via AUX input or Bluetooth signal when you pair a supported Bluetooth Device.

How do I pair my Uber FX2 with a Bluetooth device?

To connect the speaker with a Bluetooth device follow these steps: 

  • Press the BT button to enter BT mode. This will automatically put the Uber FX2 into pairing mode or automatically re-connect to a previously paired device. 
  • The blue LED on the speaker will flash indicating that it is in pairing mode.
  • Navigate to your device's Bluetooth device list and select ”Uber FX2” to connect.
  • Once paired there will be a voice prompt stating the connection was successful, and the blue LED will be lit solid. 

Note: Pressing the pair button while in pairing mode will cancel the connection.

The Uber FX2 has a stereo link mode that will allow two Uber FX2 speakers to be paired wirelessly. To set up the stereo link mode do the following steps: 

  • Connect one speaker to Bluetooth following the steps above. This will be the primary speaker.
  • Hold the Link button for 3 seconds to initiate stereo link. Do this for both speakers.
  • Both speakers will beep to indicate they are in scanning mode, and the orange LED will blink. When they find each other, they will link automatically.
  • Once the two speakers are successfully linked, there will be a confirmation chime, and the BlueLED will be lit solid.
  • The word “link” will blink on the screen. Once linked, the word “link” will stay solidly showing on both display
  • Press and hold the pair button on either speaker to disconnect

After linking, to switch the speakers’ right and left channels, press and release the Bluetooth button. 


  • If you link the speakers first, only one speaker will connect to Bluetooth.
  • If pair mode is activated on both speakers (pair button held for 3 seconds), you may encounter trouble linking until pair mode is canceled or times out. 
  • The stereo link is only for Bluetooth signal. 

Why are there Inst/Line switches, and what do they do?

The Inst/Line switches let you select your input for TRS connections so that you can turn up the volume without fear of overdriving your Uber FX2. If you are unsure of whether your input is Inst or Line, start with Line first. If that's not loud enough, switch to Inst and turn the volume back up. Devices connected via the XLR inputs will always be at Mic Level. 

Note: The Uber FX2 is optimized to provide maximum output for your source when the volume knobs are turned all the way up (5 o’clock).

What do I do if there is a delay between my linked speakers?

If you experience a delay between two linked speakers, please first try pausing and restarting your audio. If that does not work, try powering off both speakers and then re-linking them.
