HK SB20 is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Brilliant sound quality The sound bar gives true cinema surround sound of high quality. The bass isn't as pronounced as Samsung and LG but the clarity is unmatched. My only reason for not giving it 5 stars is the fact that there is no display. There is no indication of the volume or bass levels or if I'm on the correct source.

I have a Philips tv 55PUS6162/12 55" Ultra HD 4K with HDMI ARC and CEC. When I turn off the the tv the sound bar also turns off. When I turn on the tv the soundbar also turns on but there is no sound. Can you help me?

Asked by: Jonh
First make sure the CEC is turned ON.... Vera Link is turned ON... but, most important... When turning "On" .... Turn on the Sound Bar first and your TV should turn on as well.... and reverse it when turning 'off'.... turn off your TV first...

Can we use tv remote to control sb20 or we have to use its own remote seperately?

Asked by: Cako

My HK 20 is connected to my pc(analog input, portable) and my projector (HDMI) but I can't know which volume level and bass level I set. Is there an app I can use with the phone or PC to be able to have this info. Or is there another way to see it? Thanks

Asked by: Agnese

My SB20 is turning off when pressing volume up. When I press it again it turn on again. Seems like the button on the remote gives a different signal to the box. When I use the button on the box and press volume up the sound will go harder. Any ideas?
