Rated 5 out of 5 by from Excellent Sound! My wife that is a music buff is delighted with the performance, I also love the ways that the movies sound now

Rated 1 out of 5 by from can you hear me? Ever since I've had this system the bluetooth rear speakers constantly go silent. It's annoying to be watching movies and all of a sudden you lose sound in them and ruins the watching experience

Is there any way to balance the sound between the speakers and to increase the MAX volume?

Asked by: Puttnutt
You may be able to raise the volume that is being output to the LG SNC4R 420W Sound Bar w/ Bluetooth Streaming and Surround Sound Speakers by raising it on your TV or on the device that you have the Sound Bar paired with. That, in turn, will allow you to get more volume out of the Soundbar, but will be dependent on your TV or device that the Soundbar is paired with, assuming you are using Bluetooth. If you are using the Optical Digital Audio Input on the Soundbar, check to see if the audio through the Optical Digital Audio Output on your TV or device is fixed or variable. If it is fixed, you cannot change the volume. If it is variable, you can. The Sound Tuning button on the remote control (see page 9-10 in the owner's manual) can be used to adjust the sound level of each speaker...^IFV
