Hi all,

I'm a bit confused by the BeoSound Core.

Currently, this is my setup: BeoVision 7 with 2 BL20's and 2 BL4000's connected to it through PowerLink for Dolby 5.1, and a BS3000 connected to this setup using Masterlink for playing music through the BL20's.

Now, I'd like to add the BS Core to this system, with the highest possible audio quality (I don't have those BL20's just because of their looks...) and the simplest way of use.

How would this work out? Should it be connected to the aux of the BS3000 (but it doesn't seem to have an analogue output)? Or to the BV7?

Or (that would be fantastic!) could it be optically connected to the optic inputs on the BL20's, while still using the PowerLink for anything but music?

Any suggestions are very welcome!

I got the BeoSound Core today and installed it.

And I must say: I'm very, very impressed. I did not touch my Masterlink system, I just added the BS Core to the optical inputs of the BL20's and honestly, I didn't know the BL20's could sound this good. The Core in combination with the optical cables just opened up the sound of the 20's, compared to the Masterlink connection from BS3000 to BV7 and then PowerLink to the BL20's.

Wow!

And it works exactly as described in B&O's service doc. When the BL20's receive PowerLink signals (from the BS3000 or from the surround sound of the BV7), this overides the optical signals coming from the Core. But when the PowerLink shuts up, the optical signals from the Core take over.

Wow.

And this isn't even Deezer Hifi yet, it's just the regular 320kbs stream. I'll try the Hifi stream soon.

So, to summarize: optical inputs and PowerLink inputs both connected on the BL20's works just fine.

Certainly they can be driven optically. That is my setup.

As to which input has priority, my GUESS would be optical.

I suggest you PM Geoff Martin for a professional’s opinion — I am only an amateur.

You need an NL/ML converter...

That is an easy one!

You use the AUX-input of the BeoMaster to connect the PL output of the BS Core (using an appropriate cable - ask Steve/SoundsHeavenly).

Hierby you must set the Core to fixed output.

This way you have all sources of the Core as the A.Aux on the BS respectively on the BV.

Which source you use must be controlled via the Bang & Olufsen app.

Note if you stream to the Core using AirPlay, Chromecasting, Spotify Conect... just push the A.Aux button on the Beo4.

N.B. The volume control is done by the Beo4!

 

 

Another way to connect the Core is using the optical output - then an optical to coax digital converter to one of the digital inputs of the BV.

This will require the sequence of pushing the AV button and ‘the source button, you have choosen for the digital input on the BV’.

Whether that will give you a better result audiowise or not, you will have to decide by listening (this definitely is a bit more complicated).

And - the first method gives you the opportunity to use the sources of the Core in your entire ML-setup - the second doesn’t.

 

Surely you could run a pure digital connection from the Core to the BL18’s - but this would complicate your existing multichannel setup on the BV.

And you can not use the sources of the Core in the existing ML-chain.

 

The (probably) best solution is to use a NL/ML Converter (as already proposed).

 

Which solution is the best for you only testing can prove.

This would be best. It would give the best sound (purely digital connection with Deezer Hifi) and be easy to control (girl proof). I only hope it will work as you describe!

What happens if you connect the optical toslink to the Beolab 20 from the BS Core and in parallel via Powerlink the Beovision? Is there a priority on each connection in the Beolab 20?

Hi,

Yes, MM is correct, the best option is to set the Core volume to maximum and link it to the Aux socket of the Beosound 3000 with this cable:-

https://soundsheavenly.com/playmaker-and-essence-wireless-streaming/84-374-rj45-to-aux-input-cable-airplay-on-your-bo-system.html#/4-length-3m

The Beolab speakers are only designed to have one input connection at once, using multiple inputs may give unwanted noises, loss of functionality and poor performance.

Kind regards, Steve.

Hi Steve,

I'm a bit afraid of sound quality degredation because of the 15 year old aux socket. When using Deezer Hifi (so CD quality sound) through the aux socket of the BS3000, will the sound quality differ from playing a CD on the BS3000 CD player?

Hi jc,

The sound quality from Deezer should be at least as good as when playing a CD on the Beosound via this option.

Kind regards, Steve.

Hi Steve,

Really? So the aux socket on the BS3000 isn't that bad as it looks?

I hope you're right, because that would be a relief. I'm just not ready to totally get rid of CDs yet...

Have a listen and decide - and also think of the convenience of doing what you want.

You might somehow (how I don’t know) be able to measure a difference.

But whether you can hear a difference in real life or not (if there is one) is another thing.

Personally I do it this way myself - and that would be my advice for others with a similar setup as yours, too.

(Please use a good quality cable).

If I'm going to go this route, I'll order Steve's cable. Should be good :-).

Hi Steve,

I asked my dealer about. He inquired at B&O (because he wasn't sure either) and apparently, the BeoLab 17, BeoLab 17 MK II, BeoLab 18, BeoLab Transmitter 1, BeoLab 20 and BeoLab 20 MK II actually are designed to have several input connections at once. He sent me a B&O document that mentions this as a tip. It's in Dutch, so I'll translate below:

----------------------------------------------------------------------

Tip: connect several sources at once

Information valid for: BeoLab 17, BeoLab 17 MK II, BeoLab 18, BeoLab Transmitter 1, BeoLab 20, BeoLab 20 MK II

When connecting sources through POWER LINK, TOSLINK and line-in at the same moment.

Priority of sources is:

1. POWER LINK

2. TOSLINK

3. Line-in (L INPUT R)

Note: starting a higher priority source will always disrupt a source with a lower priority. A higher priority source must be stopped to be able to start a lower priority source.

----------------------------------------------------------------------

That's it. So, I've ordered the BS Core and let you know how I fare.

Hi jc,

Superb news, thanks for that!  If connecting more than one input directly to the speakers, it is important to ensure that all sources have volume control (especially the optical input, as many devices give a fixed volume optical output).

Please let us know how you get on!

Kind regards, Steve.

Steve.
