Hi there,

I posted this question already in another thread, but maybe it was overlooked there as it was at the very end and the original question was already answered. So please don't mind if this comes as a double.

 

So here is my question:

The 9500 is working in the living room and before owning this one I had a different amp working at the same place supplying music for the living room and two other rooms as well via ONE plain speaker cable and two SINGLE speakers in the other rooms.

Of course MCL should be the obvious solution for this setup, but I still have that humble speaker cable covered up nicely under the floor and I'm quite tempted to use it again and hesitate to switch to an visible cable for the MCL connection (cannot cover it without a lot of hassle). Then I thought about BeoLink wireless, which sounds good but would probably interfere with my WLAN and phone setup and, to be honest, is way too sphisticated for some bits of music in the kitchen and the other room.

Next thing on my mind was to use the MCL outputs for connecting those two odd speakers again, but it seems this could be harmful to the 9500s amp (Ohm-wise). Is that correct?

I thought about other wireless solutions and then stumbled upon sending the signal via my powerlines with Devolo dLan audio. This brings my up to the following question:

Is the line in/out the right choice to deliver a line signal to the powerline connector? It has RCA jacks and from what I understood having a line signal which is not affected by the volume control of the 9500 in the living room would give me the option to have rather quiet sound in the living room and some louder sound in the kitchen. Is that a correct assumption? Then I could simply use a cable with DIN to in/out RCA jacks and hook up the outs to the powerline adapter.

I know that the sound quality via powerline is far from HiFi, but since there is only one low budget speaker in the kitchen I don't care to much. Maybe there's a better option around the corner...or using the analog speaker cable is okay...open for suggestions...

 

Yours,

Hi Ray,

I have a BC9500 and have used MCL very successfully in the past so I wouldn't rule this out - it would be worth the effort to give control from each of the other rooms.  However I understand your reluctance to go to the trouble of hiding cables - I have just moved to a rented house where this is impossible!

I don't have experience of the Devolo dLan audio but it looks like a good bit of kit that would provide the solution that you are after.  I would just use a 5-pin DIN to RCA connector to take the fixed 'line out' from the Aux/TV socket of the BC9500.  Make sure that you get an 'output' lead that is connected to the correct 2 'output' pins on the 5 pin DIN, like this one: http://www.amazon.co.uk/Quality-Audio-5-Pin-Stereo-Record/dp/B0042UOVCM/ref=sr_1_6?ie=UTF8&qid=1398078904&sr=8-6&keywords=5+pin+din+to+rca

Hi Guy,

 

thank you for your answer. Of course MCL would be the best choice. And I'm still thinking about using the analog cables and calculating the Ohm load of my additional speakers. But the powerline version is quite appealing.

I'd wish there would be somebody around in this forum who could confirm that my first idea about using the line out as a source for the powerline connection is right: that this would give me full volume output on the line out even if I use a low volume setting for the speakers in the room the 89500 is in. So that I can control the volume in the additional rooms independantly via active speakers or additional little amps.

The cables you recommended are just like the ones I thought about, by the way.

 

Yours,

 

Ray

The BC9500's AUX connection line out is fixed - I used to use it like this in a previous house when I had it connected by cable through the wall to an amplifier in another room. This gave me fully independent volume control.

Hence the power line solution should work.

I completely agree with Guy (btw Guy what are you doing in Oberammergau?? I remember you were living in Viborg, that nice little town in Danmark, or am I wrong?).

If you already have speaker cables (cable for passive speakers) then you just have to add a 2 wire cable for power (8V from BC9500) and data + shield.

You can use Sommercable microphone cable (2 wire + shield), about 3 mm thin and available in different colours.

Next option would be to hide the MCL-Box behind the BC9500 and get the speaker cable and the white thin transceiver cable to your linkroom - if it`s not too far away...(?) You can even connect an MCL2 AV box to get an active linkroom with independant volume control (you will need an extra amp for the linkroom). 

Next option is to get a Beolink converter, and install an active Masterlink system by installing a thin ML-cable to your linkrooms.

MCL installations will be full two-way-compatible including LINK LIGHT control with TIMER programming...

Masterlink-installation is one way...

Line in/out socket on BC9500 is just a preamp out/poweramp in connection, meant to be used for inserting devices like equalizers.

To get a fixed stereo line level signal from all BC connected sources use the AUX socket as Guy said.

Hope this helps...

Hi everybody and thank you for your remarks.

I just found that I was using the wrong name for the output I intend to use. My question is still about the LINE IN/OUT SOCKET.

@ Stefan

Rest assured if there was any easy means to add cables to the existing ones I'd prefer that solution. But its a rented flat and when renovating the living room a while ago I was able to hide the ordinary speaker cables under the baseboard panels. These are fixed to the walls and painted and right now I really have no intention at all to tear them apart for more wires.

The AUX socket on my 9500 is used right now for INPUT of two sources (via switch), bluetooth and audiochannel from a Mac mini.

That is why I came upon the LINE IN/OUT socket. If that would supply a signal OUT (as Stefan said for example to a preamp) which is unaltered by the volume settings, this signal could also go to a powerline connection and on the other end to an active speaker or a little amp with a speaker. Or does whatever goes out that socket has to come in again to deliver the signal to the amp inside the 9500 for bringing sound to the regular speakers connected to the 9500.

Maybe I should draw a little setup ;-)

Yours,

Ray

That's right, well remembered!  I had to move here for work reasons.  I really hope to move back to DK someday, and Viborg was indeed a lovely place to live.  Oberammergau's a little different but great for travel, with Lake Garda only 3 hours away and lots to see and do in the local area.

But back to the thread - the line in/out socket has bridging connections between the pins to ensure that what comes out goes back in again to the amplifier (and volume control) stage. 

How about taking output from the TAPE 2 socket, or is that also in use?

But I suppose you could use the line in/out socket if you make up a lead that also provides the return path.  I think you need to bridge pin 1 to pin 3, and pin 4 to pin 4, but I would check continuity on the plug that you remove.

Hi Guy,

 

thanks for staying with me....TAPE 2 would be available but isn't that only an INPUT? If it's also an OUTPUT, is that affected by the volume settings in the main room?

Yours,

Ray

TAPE 2 is also a fixed output.  Looking at the circuit diagram the output pins (1 and 4) are wired in parallel with AUX.

EDIT:  As a silver member you can look at the service manuals here: http://www.beoworld.org/manuals_view.asp?pid=412

Part two, second page 2-4 has the stage you are interested in and is quite easy to follow.

Hi Guy,

I guess reading the circuit isn't really something I'm good at, but I will give it a try tonight. Anyways, if TAPE 2 supplies me with a fixed line level output that is good enough for me. Maybe I will want to remote control the 9500 from the other room in the future LOL and then it's back to new cables....

The outputs are still there simultaneously - you just need a suitable cable to get at them (5-pin DIN to 4 x RCA or similar).

You're right that the line in/out dummy plug needs to be there, or you'll silence the internal amps of the Beocenter.

EDIT: Tape2 is fine as well, and easier if you don't have anything connected to it right now! But... why don't you connect (say) Bluetooth to AUX and you Mac Mini to Tape2 and avoid the external switch?

Hi Mika,

for the AUX: I use bluetooth nearly all the time, so I rather seldom need to use the switch. But you are right, I could use TAPE 2 as INPUT for the Mac Mini.

I think I check for a cable with 4 RCAs and then I'll see...

Hi everybody,

 

it's been quite a while, but I just recently was able to check again for that line connection.

Here's what I found:

My solution rigth now is to work with a wireless sender station I had around in my office. This is sending the signal via radio frequency (no WLAN, no Bluetooth) to the recieving active speaker. The radio connaction works fine for my needs (its just some mono sound while doing the dishes, so I don't care too much). 

But there's a problem: the radio connection works best if the sender recieves a strong input signal (read: LOUD). Right now it works when I connect the sender to the PowerLink out. This way it is of course affected by the output level in the main room. As long as I play my music at a quite „present“ volume level in that room, everything is fine. But as mentioned in the former posts I want to be independent of that rooms volume level.

It was suggested that I'd use the TAPE2 outs instead which would give me line level. The problem now is that line level has a too low output to give a strong signal for the sender. Which gives a low volume level in the recieving speaker. And when I crank up that speakers volume to the max it gives a lot of static.

IS THERE ANY WAY OF ADJUSTING THE LINE LEVEL?

Hope somebody can help here...
