Question: my IR remote isn't working at all, what should I do?
Document: I connected my soundbar straight to the TV along with my BluRay player, HD-DVR, etc. and I was in business right away. The IR remote control is easy to use, although I've since replaced it with a universal remote for all my devices (which works fine, too).The first thing I did was to fire up my BluRay player and play an action movie to see how much punishment I could inflict on the subwoofer/soundbar.
It was simple to set up, sounds great. I know the complaint is the price but you get what you pay for. They do however leave a lot to be desired as far as a remote goes.
HK soundbar is excellent. I am not an audiophile by any means, but I know good sound when I hear it. This unit was easy to set up, and sounds great. I think it is a reasonable price when compared to other high end soundbars, such as the Bose unit. The only complaing I have is the lousy remote that comes with the unit and the 3 LED colored lights to identify what setting is being used. But this was not enough of an issue to take a star away.
I originally bought the Bose GS series II system with gemstone speakers; It was an overall good system but lacked DTS decoding. This Harman system has both Dolby Digital and DTS decoding and sounds great. The remote is simple and has a number of listening modes to choose from. It has also a wireless subwoofer with deep base that you can tuck away out of sight. I highly recomend this system, you won't be disappointed...Changing my review since this post.
You have to use it for volume, etc... Mine stopped working the second day. I replaced the battery and it came back to life. I have a feeling these units have been sitting on the shelf for awhile since they were introduced a few years ago.
The remote for the Sound Bar 30 is defective and I can't get Harman Kardon to respond. It has gone through 6 batteries in less than 3 months. the last one I put in last evening and tonight it is already DEAD! Trying to adjust without the remote is next to impossible. The sound bar 30 I would give 4 stars IF it had a workable remote but at this point I would NOT recommend this equipment.Harman Kardon has replaced the defective remote so I am now very satisfied with the SoundBar 30.
I'll give that star to the sound when it's working properly, which is about 10% of the time, because it is still a massive upgrade from TV speakers.
The Soundbar is larger then the 50 inch TV, but the sound is great!Only after you turn the unit off and hear the TV speakers alone do you realize how good it's working.At first I wasn't impressed but the unit actually learned the room size and sounds better then it did when I first plugged it in.Yes it cost more then the TV, but it adds the missing link of actually being there.
I get confused when the biggest comment read on these was that it lacked bluetooth or HDMI input/output. What this is ... is a sound bar that was created with all the quality you would want in doing ONE thing well. Quality made, quality packed and working with no challenges I am highly please. The tipping point (for me) was the savings in buying through Amazon. Savings was appreciated!
Everyone should replace it with your universal remote of choice. In the "looks" department, the SB30 also wins. The soundbar is unimposing, totally black, with just 3 LEDs that use movement and color to make them actually useful and intuitive. Very nicely designed.Unfortunately, the deal-breaker for me was the subwoofer which has issues. First, is interference between the speaker and other wireless devices. Crackling occurs frequently on the subwoofer.
Answer: If the remote still doesn't work after replacing the battery, contact Haman Kardon for a replacement.  I've found their customer support to be good.  Another suggestion would be to find a good replacement remote that integrates the sound bar functions along with the rest of the home theater.  Logitech has several integrated remotes that are compatible with the SB 30.
