inking Two Speakers
If you would like to play music from a Bluetooth device, you can first “link” two Block Rocker®
speakers together in order to listen to your music in stereo. One Block Rocker® will serve as
the left speaker and the other will serve as the right speaker.
To link two Block Rocker® speakers together:
Note: Before you begin the Stereo-Link™ process, any connected Bluetooth devices will first
need to be disconnected by pressing the Bluetooth button on the speakers.
1. Press and hold the S
tereo-Link™ button on one speaker to enter Stereo-Link™ mode. This
first unit pressed will be the primary speaker (Left channel). Then press and hold the
S
tereo-Link™ button on the second speaker. This will be the secondary speaker (Right
channel). During the pairing process, the Link icon on both speaker displays will flash.
Note: The linking process can take up to 30 seconds to complete. Speakers should be within
50’ (15 m) of each other to properly link. The closer the two speakers are, the quicker the
link is established.
Once linked, the Link icon on both speakers will be lit solid. The Bluetooth icon on the
primary speaker will flash indicating it is ready to pair to a device. The Bluetooth icon on
the secondary speaker will be lit solid.
2. Navigate to your device's Bluetooth settings screen, find B
LOCK ROCKER, and connect.
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. Playback controls are active on both speakers.
T
o disconnect two speakers or cancel linking between the two, press and hold the
S

from the primary speaker to indicate the link has been broken (if voice prompts are enabled.)
Note: Press and hold the Power button on each speaker while in Stereo-Link™ mode to power
o the connected speakers. Block Rocker® speakers powered o in Stereo-Link™ mode will
automatically enter Stereo-Link™ mode the next time they are powered on and begin
searching for secondary speakers to connect to.

I
f you can’t hear the microphone over the music volume: Turn down the music volume from
your source or increase the microphone volume using the M
ic + button.
I
f there is too much bass: Try adjusting the tone or EQ control on the Block Rocker® or your

I
f you experience audio dropouts while playing music from a Bluetooth device, this may be
happening because your unit is trying to link to another speaker. This can occur if you power
