Is there any way I can stop any unwanted people connecting to my sound bar?

Asked by: Jackjack5000
We regret the inconvenience you have experienced with this system pairing. It is suggested to attempt resetting the system in order to revoke this pairing. Press the VOLUME DOWN button on the main system and the SOUND EFFECT button on the remote control simultaneously for a full second to reset the microcomputer of the speaker. ^AC

The sound bar works great and is loud with Bluetooth to a phone but when plugged into my tv it doesn't get as loud.

Asked by: Pipeliner
We apologize about the issue you are having with this sound bar. How is the sound bar connected to the TV? Is the volume turned up on both devices? We would need to gather more information to better address your concern. Please contact our Customer Interactive Center at 800-243-0000 for further assistance.
