The ION Audio Block Rocker XL would be able to link to one additional Block Rocker XL speaker.

To link an additional speaker:

  1. Press and hold the Stereo-Link/Repeat button on both speakers to enter Stereo-Link mode. You will hear a tone and the Stereo-Link and Bluetooth icons on each speaker's display will begin flashing while they search for each other.

  2. Press and release the Bluetooth button on either speaker to select Bluetooth mode and begin the Bluetooth pairing process. The speaker you use for Bluetooth pairing will become the primary speaker.

  3. Navigate to your Bluetooth device's setup screen and find Block Rocker XL. Then connect and you will see the Bluetooth icon on the primary speaker flashing to indicate it is searching for a Bluetooth device to pair with.

When the connection is successful, you will hear "Bluetooth Connected" from the primary

speaker (if voice prompts are enabled). When audio playback begins, you should hear it

through both speakers. 

The primary speaker will play the left channel while the secondary speaker plays the right channel. 

To disconnect two speakers or cancel linking between the two, double press the Stereo-Link/Repeat button on either speaker.
