The intensity of the light show is dependent on the amount of audio signal being sent into the unit.
If you are experiencing a light show that doesn't move around very much, it is likely that you are not using a feature on your phone called Bluetooth Absolute Volume*. This means that the volume of your phone/tablet/device is controlled independently from the volume of the speaker.
So, if you have the Pulse 4 set to maximum volume or close to it, but the volume on your device is set at a low level, the light show will show little to no effect. All you have to do is reverse it. Turn up the volume on the device to the maximum and set the Pulse 4 to the desired volume. This will send the correct level to the speaker and the light show will show plenty of effect. This also benefits the sonic quality as well. Therefore, we recommend always having the volume on your device turned up to a high level and then adjusting the volume level on the speaker itself. This way you'll be able to enjoy the light show while also getting good audio quality. Or, if possible, setup your device for Bluetooth Absolute Volume*.
*BLUETOOTH ABSOLUTE VOLUME: Most phones/tablets/devices now use Bluetooth Absolute Volume (a.k.a. volume sync) by default. This is a feature that synchronizes the volumes of the device and the speaker, and allows the speaker volume to be controlled by changing the volume on either the device or the speaker. The volume being sent from the device is fixed at full volume.Was this helpful? Thank you for your feedback! -
This was done to strike a balance between functionality and ease of use. More than three button pushes on the Smart Button could be annoying to the user, so three settings were chosen: Off, Low (optimized for office settings) and High (optimized for outdoor settings).Was this helpful?

Reset the Soundbar by the same process as when doing "reset remote settings": 1. Switch the SB 350 ON. 2. Press and hold the Surround and Volume (–) buttons simultaneously for about 3-4 seconds, then let go.
