Hi  My new tv and speakers (Beovision 14-55, Beolab 5+3) is sendong speech sound out in all speakers. The ssetup shows that everything is fine - I can hear the individual sound in the right speaker - but it does not seem to separate speech from non speech - any solutions before i call B&O and complain?

Hi Jesper,

Three questions:

- What are the Speaker Roles assigned to your loudspeakers? Are you certain that it's Left Front, Right Front and Centre Front?

- Is this only happening with 2.0 sources or is it also occurring with multichannel signals?

- Is the Sound Mode using "True Image" or "1:1"?

The True Image upmixer will "bleed" some speech signals to the Lf and Rf loudspeakers if you are upmixing from 1.0 or 2.0 signals. This may also occur if you have (for example) a 5.1 input, and only a 3.0 output.

Cheers

Just a guess, but I am assuming you have configured each speaker set to a particular role?

BL5's - L/R fronts, BL3's L/R Surrounds, Avant L/C & R/C to C only

Then each set for your sources i.e. Movies, Music, Adaptive, News etc?

I think the default adaptive will do as you describe - play voice to all sets. So if you have not done the setting up above work configuring the loudspeaker sets, groups etc...you need to.

As you have a BV14, if there is a problem....call your Dealer to tell them to come and fix it/set it up properly for you.

Yes all setup that way

- Is this only happening with 2.0 sources or is it also occurring with multichannel signals?

I have not seen anything else than 2.0 signals in: Settings: Sound, Sound info - and tried multiple channels

- Is the Sound Mode using "True Image" or "1:1"?

I have tried both - worst under 1.1

The True Image upmixer will "bleed" some speech signals to the Lf and Rf loudspeakers if you are upmixing from 1.0 or 2.0 signals. This may also occur if you have (for example) a 5.1 input, and only a 3.0 output.

- Yes that is how it is setup

Already done - same issue

If your input is a 2.0 source, then the input channels are "Left Front" and "Right Front". If the TV is in 1:1 mode, then I would expect that the signal should only come from your loudspeakers that are assigned the Speaker Roles of  "Left Front" and "Right Front". There should be no signal in any other loudspeaker in this case.

If "True Image" is turned on, then I would expect the signal (in most cases, the dialogue) to be produced by the speakers with Speaker Roles of Left Front, Right Front, and Centre Front.

If this is happening, then everything is working normally.

Note that the "Adaptive" Sound Mode is not a sound mode. It tells the TV to select the other sound modes automatically based on DVB metadata.
