What People Are Saying

Rated 4.1 out of 5 by 14 reviewers.
Rated 4 out of 5 by GOOD SOUND. ADDS TO QUALITY OF SOUND, MAKING TV MORE ENJOYABLE.HOWEVER, HAVING TO USE TWO REMOTES, CABLE REMOTE FOR TV AND CABLE BOX, AND SOUND BAR REMOTE FOR SOUND BAR IS NOT THE BEST SITUATION. THEREFORE, IT IS NOT EASY TO USE!!! July 29, 2014
Rated 4 out of 5 by Good sound; nice narrow look! Was looking for a sound bar with a low profile and good sound. Found it - plus it worked well with my LG TV. June 28, 2014
Rated 5 out of 5 by Great item This sound bar has great sound, lookes great and is reasonably priced.. It was more than I expected from a sound bar. June 20, 2014
Rated 1 out of 5 by Not worth the extra money. It really is not a user friendly system at all. To type in anything you have do it with remote letter by letter. It requires both optical and hdmi cables. It does not allow my tablet to show on tv or run the system. June 18, 2014
Rated 4 out of 5 by Great sound bar This is a pretty good system but if you are use to a 1,000 watt this system is not as long or strong. June 16, 2014
Rated 4 out of 5 by Solid Sound Bar Set-up This sound bar is easy to set-up and get started with right away. It has a nice design that can fit in with most modern TV/entertainment center designs. June 7, 2014
Rated 5 out of 5 by Sounds great Once I learned how to use the soundbar sounds great looks good but hard to keep it from lowering from the TV. Love the sound and volume. May 25, 2014
Rated 5 out of 5 by Perfect for surround sound effect w/o the cost The sound bar was the best purchase I've made in some time. I get the surround sound effect without the high cost or wiring required for surround sound. I plan to buy another for my second Tv. May 16, 2014

Answer: 
Thanks for your interest in the 4.1-Channel Soundbar with the 6 1/2" Wireless subwoofer. I believe the model number for this unit is the NB5540? The display has a sleep function for it and it definitely will turn off after a while depending on how long the sleep timer is set for. Conversely, after the unit has been turned on, if it does not receive any signal from the connected TV for a certain period of time, it will automatically turn off! You can also turn the display off by cycling through the sleep timer settings until "10MIN" is displayed and while that is displayed, pressing the "Sleep" button once more turns the display off. IFV

Bought this product from the Store in Dublin, CA. Product has no printed owner's manual in the box. It does have a CD entitled Owner's manual and SmartShare PC Software which is of no use to me as work on Mac's. Is there a CD Available for Mac OS or is there Manual available online?

When listening to music through bluetooth, the sound from the sound bar is great and loud. However, when we switch to TV, the sound is not even close to loud enough. I know the sound bar is capable of being louder since it works well with music, so why can't I get the sound to be louder while watching TV? Even at the max volume level, the sound bar is no louder than my TV speakers.

Answer: 
Thank you for you question on the sound intensity differences between a Bluetooth source versus that from your TV on your LG 4.1 Channel Soundbar Model NB3470.
How is your TV connected to your SoundBar, HDMI or Optical? Have you gone into your TV's Sound Settings to see if you have the output changed to the right output mode for the connection you're using and does your TV have a fixed volume setting and an Auto. Are you able to set the volume output on the TV higher or lower and have you also checked your cable box settings for the audio output.
The point here is that there are many more things to consider that might be limiting your sound intensity versus just sending directly via Bluetooth and not having to tamper with the signal being sent.
It's the same as when you connect your Bluetooth heaphones to an MP3 player or to your phone. If the volume is low on your source(i.e. the phone or the MP3,) your volume on the headphones will only go so loud. To get more volume, you'd have to raise it more so that you have more to work with on your headphones! This is the same principle with your SoundBar and your TV, but now throw in your cable box! All those will affect the overall volume you can get from the SoundBar! If you're still having issues, please contact Customer Support at (800)243-0000...IFV

Answer: 
We appreciate your interest in this Sound Bar system. The simplest method for connecting this system to a network would be to connect the LAN cable from the LAN port of the player to your network router. Connect your HDMI port directly to the TV, in order to see the SETUP menu on the TV screen. If you have additional questions, please contact our Customer Interactive Center at 800-243-0000.

How to turn off Auto Shut off?

I love the sound bar and it goes very well with my 55lm6200. It's kind of annoying when it turns off if I don't use the sound bar for five minutes and I can not find the setting to turn the auto off feature off.

Answer: 
The screen saver appears when you leave the unit in STOP mode for about 5 minutes. If you set this AUTO POWER OFF option to its ON setting, the unit will automatically turn off within 15 minutes from the time the Screen Saver is displayed. Set this function to OFF to leave the screen saver until the unit is operated by the user. This information is located on page 28 of the owner’s manual.
