Left & Right speaker gain adjustment

[sublover]

hi guys,

I was wondering, before buying the Wiim Ultra streamer if the app provides left and right speaker gain adjustment. Like in Roon you can set this to match speaker output. I can get a nice center stage. My left speaker needs 0.3 - 0.5db gain to get the center solid. I dont mean left right balance but sperate gain settings.

Thanks

No. There is no such setting.
What‘s the difference compared to setting the balance?

thanks Aquaman for your quick reply.

Balance left and right adjusts more than gain. The imaging will be different.

With gain left and right sperate , when you adjust 1 it wont effect the other speaker.
Thats why Roon DSP works great for me.

i dont think its difficult to implement this feature

Balance only affects gain. Both speakers yes but only gain.

thanks Slartibartfast, i see, but still it would be ideal to only up te gain of the speaker thats a half a db short. Dirac works like that too. Do you think the devs would be able to implement that?

It's better to be in negative on a channel...because otherwise there will again be an increase in probable clipping...if it's upstream
You can also go down to the overall level afterwards... but if I understand correctly, that makes your considerations irrelevant...

Couldn’t l/r peq be used?

Hi Canard, i agree on negative db.

I have a C399 with Dirac and LS50 metas
No matter what i try the center image/ vocal is to the right side. I measured with REW and confirms left speaker is 0.3db less than right. My living room is not symmetrical. Than i found out in ROON that i could ad 0.3db and distance. Center locked holy cow.

yes Dirac is designed to compensate but 9 out of 10 measurements it screws up

So my last hope was a Wiim product where i can manually adjust. And not balance, i can adjust balance in Bluos but it will introduce artifacts.

If i sell my NAD and buy the Wiim i could be happy. English is not my first language so i hope you guys understand what im asking

There's a much simpler, less technical way. No measurements, but no less accurate... Center the image using the balance and... the available "mono" function, in wiim home.. I initially requested these two functions for this very basic use.
Over the years... I think the significant advantage of combining these two functions for adjustment has gone unnoticed... what a shame
;-)

I have one tv setup where the main seating position is not central between the speakers.
Simply adjusting ('rotating') the speakers a bit made a huge difference to the centering of voices etc.
Not perfect, but dramatically better.

"Distance" really means "delay". And no, the balance slider does not change that (although it has been requested in the past, search the feature request sub-forums).

Personally I doubt that a 0.3 dB channel imbalance can make the difference between "disturbingly off center" and "center locked holy cow". 0.3 dB is a lot less than the typical pair matching of loudspeakers. If anything, the increased distance setting could have attributed to this change in the vocal frequency range. This kind of supports your point, but the feature - introducing additional latency, btw. - hasn't been considered yet.

And not balance, i can adjust balance in Bluos but it will introduce artifacts.

That sounds like a broken implementation to me. Technically, the balance control should be nothing but simple per-channel volume control.

English is not my first language so i hope you guys understand what im asking

Lots of non-native speakers here, don't worry.

This is surely the correct way to do it.

@sublover, if my above assumption is correct that the delay had its share of the improvement you noted, then maybe placing your speakers slightly asymmetrically (plus adjusting the level in mono, as suggested by @canard) is the way to go. Move one speaker closer to you. It's not exactly the same as digital delay, because the interaction between the speakers and the room will change slightly. But this is what room correction should be able to fix.

Would you keep the C399 as a power amp?

And while I've been wasting 2 minutes of everybody's time, @Mr Ee decided to put it into a single sentence.

 

[sublover]

Thanks Harkpabst. But physically adjusting delay will make me move the speaker to much. Its in the living room and i have waf... Just an easy delay fixes it
