hi,
I cheated this week. This week's B&O Tech article is a video from our Technical Press event for the BeoVision Avant.

Have a good weekend.

Very interesting. Thanks. I never thought the voice would sound so much different depending on using 2 stereo speaker rather than 1 mono.
Barry Santini:My only suggestion is that, in future presentations, you consider exchanging "Avant" for "TV."

Hi,
I enjoyed the video and am enthusiastic about the new Avant. I wondered though, at the end of the video, you point at the three channels in the avant as being the center. Isn't that causing interference as the sound comes from three speakers instead of one? Wouldn't it be better to only use the real center then, and leave the left and right of the avant unused in such a setup?
Cheers,Tommy

Hi Tommy,
The short answer is "yes" - but the real answer is more complicated, so I'll give it a shot:
It depends on the channel allocation of the three loudspeakers and the content of the signal coming into them. Of course, if you have external left front and right front loudspeakers (as we did in the presentation that you see there), then one possible option is to set the three internal loudspeakers to Centre Front. In fact, this is what I did for the 7.1 demo - however, I dropped the levels of the Left and Right loudspeakers by about 6 dB to ensure that the interference that you've pointed out would be reduced. That difference in level was tweaked by ear - it would be different in differently-sized rooms.
In cases where you do not have external front loudspeakers, then the three internal loudspeakers would be set to Left Front, Centre Front, and Right Front. Then, there would only be interference if the incoming audio channels are correlated. (As a simple example, if the three loudspeakers are individually playing Beethoven, Britney Spears, and John Cage,then there will be no interference. On the other hand, if you're playing a 5.1 multichannel mix of a Sting album, then the lead vocals (which he typically mixes into all three front channels) will cause interference.)
The advantage of the flexibility of the Speaker Groups (available in the BV Avant, as well as the BeoVision 11 and BeoPlay V1) is that you can choose. If you start with just the television, you will probably want to set the internal loudspeakers to Lf, Cf, Rf. However, if, in the future, you upgrade to external front loudspeakers, then you can either set the internals to None, Cf, None OR Cf, Cf, Cf, OR something else - according to your tastes and needs.
For example, I have a BV11 at home, and I have external front loudspeakers. However, I have one Speaker Group that disables the external loudspeakers and just uses the internal loudspeakers as Lf and Rf for situations where I don't want the big externals playing along (i.e. late-night listening or just watching the news).
cheers
Hi Geoff
An excellent presentation. Very simply stated and clear enough for even me to understand :-)
MH
Great video. You are excellent at explaining these advanced concepts.
Slightly off-topic, will you make a blog post about some of the new things going on in the Beolab20?
Great stuff Geoff
