Hi  everyone,

Just want some advice really, i have a full beosystem 4500 with a pair of beolab 5000 wall speakers from fronts, and beolab 3000's for rear.  aslo with this a beolab 2 subwoofer.

All this i had fully intergrated with a AV9000 television, this worked perfectly using an AV9000 audio kit (beolink 1610 converter box) for the masterlink connection.

Sadly the AV9000 has become faulty turning off anywhere between 5 and 15 mins.

Playing a cd or record i got longer playing time before again it turned off.

After much thought on  was it worth trying  to repair the AV9000 i decided to buy the latest possible beovision 7, which i have just had within the last week.

This is  the last version, a 2012 made unit being a 7-40 mk6 with the LED edge lighting and blue ray player.

Its also been made up with the motorised stand with a beolab 10 triangular centre speaker which is very rare, but looking as close to the AV9000 as possible.

I love the picture, but the sound output is terrible compared to when the AV9000 was connected.

I have done side my side tests playing the same music, the beovision 7 gives no bass output to the rear belab 3000 speakers at all, and when watching a film, the sound is lacking in bass all round, and the centre speaker drowns out the rest of the speakers in the room.

On the audio side, i had to tell the beovision 7 that there was no subwoofer connected as it sent all the bass signals to this and non to the beolab 5000's and 3000's sounding awfull.

Now the beovison 7 thinks there is no sub in the system, i'm now getting a full bass signal to the  beolab 5000's fronts, but still no bass signal to the belab 3000's rears.

Its still sounds poor compared to having the speakers connnected to the AV9000.

How can this be for a virtually new high spec beovison 7?

Any ideas, it was set up by people who knew what they were doing, i've tried altering the speaker settings, but cannot get a marked improvement.

I'm wishing i just got the AV9000 repaired now, it maybe old and the wrong format in todays world, but build quality was top class on the older model, and from what i've been reading, somwhat of a cult beovision today.

Any thoughts on what i have talked about would be great.

thanks

Phil

Forgive me if you have done this already but have you set the correct output settings from the bluray player settings.

There should be the option to have the audio as linear PCM or bitstream if it is on linear PCM set it to bitstream as when watching a 5.1 movie the bass which is the .1 should be directed to your subwoofer.

Also sometimes you have to go into the audio selection on the bluray movie itself where you can tend to choose from dolby digital true hd or dts hd surround sound depending on the movie and although the beovision 7 doesn't have an hd decoder built in you will still get 5.1 surround sound.

I myself would start again and set the speakers back to the factory default but this time ensuring the audio option on the bluray player is set to bitstream, from there i would tell the tv which speakers are connected to it.

Once again forgive me if you have already done this.

What makes you think, that you'd getter a better result from setting the player to bitstream?

Just that in my experience using the decoder on a loewe tv i had i know it's not a beovision 7 i had it setup to PCM on my bluray player when i was using my beolab 14s. And although it sounded ok it didn't sound as good until i changed the settings.

Once i changed the setting to bitstream on my bluray player i noticed a big improvement in audio and it outputted dolby digital or dts whereas before it would be PCM on the info bar.

After making the changes when calling up the info bar on the tv itself it would display the output setting which was either dolby digital or dts 2.1

AV900 and BV7-40 MK6 are completely different products. The old AV9000 uses analog 4 channel dolby surround module, called Doly Pro Logic.

There is a SPEAKER 3 mode with three front channels LEFT - CENTER - RIGHT and SPEAKER 5 mode with 4 channels LEFT - CENTER - RIGHT - SURROUND. 

BV7 uses a digital surround decoder with up to 7.1 channels, usually we use 5.1 with LEFT - CENTER - RIGHT - LEFT SR - RIGHT SR and LFE, the .1 channel.

It is important to assign the BLs correct in the Speakers menu. I think BL5000/3000 won`t be present to choose in the menu. They are too old. So try BL8000 or Pentas for the fronts and maybe BL6000 for the rear. Set one PL port to Sub and connect the BL2. (select BL2 in the menu).

For listening music from your BS4500 via this system , only use SPEAKER 2 or SPEAKER 4 mode.

If you use the DD decoder (SPEAKER 5 mode) it is normal, that you have less Bass in the rear channels (BL3000).

2nd option can be , set Sub to none, connect your BL2 to the front Powerlink port and connect your Bl5000 to BL2 outputs.

Hope this helps

Stefan

It might be, that you like the lossy Dolby/DTS tracks better than the lossless Dolby TrueHD/DTS HD Master Audio tracks - only you will know that.

The BV7 can not decode these HD sound formats and therefore picks the lossy DTS core signal/the DD (if available), when you bitstream to it.

Letting the BRPlayer do the decoding job means, that you will get the HD tracks as a losless (5.1/7.1) stream, which is perfectly right for the BV7.

Of course I can say anything to the way the BL14 set was hooked up to your Loewe, but it might have had something to do with that.

Personally I have let my BRP decode the HD-audio from the BRDiscs to PCM for my BV 5.1 setup without any issues - no bass problems there.

thanks steffan,

after speaking with who sold it to me, i re named  the rear speakers as pentas also, and now i have a bass output to them, both front beolab 5000's and rear beolab 3000's are now named as 'pentas' . I was told from an B& O engineer that the beosytem 3 engine would cut off bass signals if you named a speaker type as a small output one as it thinks  a full bass output would damage it. Making all 4 pentas now improves the sound, but still doing a like for like test connecting the AV9000 back up compared with the Beovison 7 MK6 the sound from the AV9000 playin a CD walkes all over the beovison 7, really dissapointed with the overall sound from the beovison 7, i really was not expecting a drop in sound quality on the audio side of things.

HI stefan,

I also told the beovison 7 that there was no sub connected to it which gave bass output to the fronts (before there was non ) the beolab 2 sub is connected now as i had before tapped off the back of the right front beolab 5000 powerling socket, so you get the bass output from the lab5000 and the sub, its ment to be  the other way round i know, but you loose the bass from the wall speakers then.

 It still sounds worse playing a CD off the beovsion 7 than the AV9000, with the AV9000 the bass is absolutely amazing, its warm, clear, and loud, the sound envelops you having the 4 beolab panel speakers on, it just sound thin and lacking on the beovision 7. Why is this for a state of the art very expencive modern B&0 telly?
