Hi everyone

This might be a bit of an amateur question but it’s got me stumped!

I have just bought a Dali Kubik one soundbar based on the fairly universally good reviews.

However after plugging it in to my tv I’m a little Underwhelmed. The sound is fairly flat with no presence and hardly any base even on the full base setting.

So, my initial thought was go to the tv (Samsung) settings and play about with the eq. But when I go there it says these options are not available when using the optic cable.

So I suspect the sound is flat because the eq is set to be completely flat as that’s what it sounds like.

So, how do I sort this out? Or am I stuck with it like this as it’s the tv that’s the problem!

Thanks in advance if anyone can help.

Might be obvious, but our soundbar has settings for voice/film/music etc. Be worth checking if yours has.

The optical out on your TV is a digital output and is therefore sending a digital signal to the soundbar.
The soundbar has a digital to analogue convertor to turn the data into sound.

You need to see what settings are available on the soundbar or connect it to the TV using an analogue input/analogue TV output and then you can adjust the settings on the TV.

At a guess I would say the OP needs to RTFM.

From the What HiFi review:

A sub out socket lets you hook up your own subwoofer if you feel the need. You shouldn’t have to, however. There’s also a switch to adjust the amount of bass depending on the position of the soundbar.

The ‘Neutral’ position offers the least bass, and is best when the soundbar is near a wall. There are keyhole-type mounts at the back, in case you want to stick it on a wall.

At the other extreme is ‘Bass Boost’, which does just that. It’s best for filling larger rooms (or blowing the roof off smaller ones).

The halfway point is ‘Bass Enhance’, which provided a balanced sound in our set-up: on a rack, in front of a TV.

OP RTFM (read the fking manual)

Yes I agree I think changing the connection is the best option.

I wasn’t sure if someone knew a way you could change the settings of the signal from the tv using the optic cable. This seems a bit of a flaw in using optic cables.

Thanks.

Thanks tony. I have read the manual and had already adjusted the bass boost. As stated in the original post if you re-read it.

What I asked was about adjusting the eq on the tv when using an optic cable.

Maybe you should rtfp

Cheers anyway.

Sorry, I thought you were referring to the "full base (sic) setting" on the TV, not the sound bar.

The sound bar has "aux in" sockets, so I suspect you could take a feed from your TVs "line out" sockets (if it has them) and connect those to the "aux in" on the sound bar.

You could probably even connect the TV headphone out to the aux in sockets as well.

Do note though - the sound bar only has two small 130mm woofers, and you're not going to get loud, deep bass from those, especially in a large room.

Doesn't an optical out simply by pass all sound controls on the TV itself. Isn't that the whole idea behind any digital output ?
That its purposet instead of adjusting the result via the TV you adjust the result from whatever tone control settings are on the device the other end of the optical cable plugs into be it sound bar amp whatever

Just out of interest, how long does the sound bar need to be run in for?
As out of the box I've always been disappointed with speakers of varying types. But after a few hours useage they have a significantly better sound

Wow, that's a bit personal.

I did apologise to the OP (which you have ever so kindly quoted), I had ever so slightly misread his post, and thought he had only adjusted the TV sound, and not that of the sound bar.

But nevertheless, thanks for your contribution, I'm sure you've never made a mistake.

Getting away from the unnecessary personal insults one important thing the OP should consider is the CHOICE of optical cable.
Whilst they all do exactly the same thing ie transfer digital signals from one device to another and with the same effect they are not all the same.
The digital signal can be influenced and corrupted along this most important of journeys.

For this reason I suggest the OP considers this excellent choice

https://www.russandrews.com/kimber-opt1-2650999202...

A snip at just £49. And a quantum step up from a bundled cable that will do exactly the same thing. Remember the fact that you may not hear any discernible difference in sound between the cables is irrelevant. Its the fact that you could hear differences that is the crux of the matter.

I'm genuinely interested to learn how a beam of light carrying a digital signal can be influenced by the choice of fiber optic cable (especially in the home for short lengths)?
£49 sounds a bit 'audiophile' to me.

From a review:
Well made = fair enough
easy to connect = ok
improved transparency and detail = bullst alert

But this is only because they failed to hear the difference. Had they heard the difference the review would be different.
They are the sort of people that cannot understand the importance of having audiophile grade fuses in their plugs
At times I despair of the narrow mindedness shown towards these excellent innovative products.

I love that guy's super-sarcastic review.

However, why are they even selling those cheapo black fuses when you can buy their £130 blue fuse?

The convenience of the quicker break in time is very interesting
the cost is higher but still a bargain

Thanks for all the replies, including the rtfm!

No insult taken, as ph goes that’s quite tame!

I haven’t had time to go back to the shop yet but I’m going tomorrow.

On the cable, it didn’t come bundled it cost £60 but I got it for £25 in the sale. It’s from richer sounds, I don’t know if they have a reputation for rip off cables? The guy in the shop was adamant a more expensive cable was better and more ‘reliable’. I didn’t quiz him on how a digital signal can be better as I have always been told it can’t make much difference. I did some research when I got the tv and that was the conclusion with hdmi from most of what I read. But for £25 in the sale seemed a good idea.

Running in, yes the manual does say 50 hours run in. I was a bit sceptical but it does seem to be getting better and well respected websites seem to confirm there is such a thing! I’m giving it an extended test today at much higher volume as I’m home alone.

The only thing I can’t get my head around is no control over the equaliser. The sound is flat and base none existent as if it’s all set to flat. I have found some people complaining that plugging sounds bars directly into the sky q box optical have the same problem as the q box has no eq either. Might try it anyway to see if it sounds any different.

I realise I will lose some sound quality by not using the optic cable but I think the trade off of being able to adjust the base and eq through the tv will be worth it. Otherwise it’s a very expensive average sounding soundbar.

I will update what happens after I’ve been to the shop tomorrow.

Thanks for everyone who has replied.

Just a serious reply regarding the optical cable, and the need for high cost ones (or not).

Optical TOSLINK cables are generally recommended not to exceed 8 metres.

I recently wanted to link a Mac system unit to the 5.1 surround processor - across the opposite side of the room.
Running a cable round the outside of the room would mean a cable length of around 14 metres.

I took a risk and ordered a 15 metre optical cable from Amazon - for the princely sum of £6.99, on the basis that another reviewer said it worked fine for them.

Plugged it in, and it works perfectly, so whatever the issue you have, I'd think it's unlikely to be the (short) optical cable.
