I'd need a bit of advice:
If I purchase the RJ45 to 3.5 minijack adapter from Sounds Heavenly to connect either headphones or an AptX Bluetooth Transmitter to Beovision 11, what settings do I need to make on the Beovision 11?
- what speaker types to use for the RJ45 powerlink socket to which the adapter is connected? Would PL1 Left and PL1 Right set to "OTHER" do, or should I select some BeoLab for both?
- speaker roles: should PL1 Left (OTHER) be selected as Mix Left and PL1 Right (OTHER) as Mix Right, or how should the speaker roles be configured? The internal speakers of BV11 I'd of course switch off for the headphone speaker group.
Are there any other settings to consider?
The idea is that I could switch to headphones (wired) or alternatively wireless using the AptX Bluetooth Transmitter simply be selecting a speaker group I'd name "Headphones".
I couldn't find a topic about this on the forum, but perhaps someone has done this and could share their instructions. Thanks!

I was thinking of getting the exact same Avantree Priva transmitter as you :)
I also sent an enquiry about using this RJ45 powerlink to 3.5mm minijack adapter with BV11 to Sounds Heavenly:
http://soundsheavenly.com/televisions/32--v1-headphone-adapter-.html
Sounds Heavenly are the specialists in B&O compatible cables and also advertise on BeoWorld, maybe they have experience in using the cable. V1 and BeoVision 12 are mentioned in the product's description, but I think BV11 should work pretty much the same way.
KMA: - speaker roles: should PL1 Left (OTHER) be selected as Mix Left and PL1 Right (OTHER) as Mix Right, or how should the speaker roles be configured? The internal speakers of BV11 I'd of course switch off for the headphone speaker group.
Hi,
Are you planing on running the headphones alone, or will the loudspeakers be playing at the same time?

Ramasjang:What would be the difference between using the rj45 or the headphone jack on top?
Ramasjang:I am not sure if I understand you.... I have the minijack, USB, hdmi on the top back panel of my BV 11. But with the rj45 you can play with speaker groups... I am not sure how the minijack works...
Not saying that is good that they removed the upper panel, but still I wonder,
how many people actually want to use headphones with their tv?

There is a tv - and there is a BV

KMA:All other speakers would be off, when the Speaker Group named "Headphones" is selected. There is "LINE" in the Speaker Types for the RJ45 powerlink connection settings, but that is fixed, not variable, so selecting it for "Headphones" won't do, as volume could not be controlled with the remote. And if I select any BeoLab or Other for the Speaker Type for the RJ45 -> 3.5mm adapter, the Speaker Roles allow only one role to be assigned to a speaker, so the output could only be set as Right or Left, but not both e.g. Stereo. Example: PL 1 Left set to Speaker Type "Other", Speaker Role set to "Left". Wouldn't that result in mono left channel sound from the headphones? So will using a RJ45 -> 3.5mm adapter require the use of both PL 1 Left and PL 1 Right outputs, combined to one 3.5mm output, with Speaker type set to "Other" (for both PLs) and Speaker Role to "Left" and "Right" respectively? And is such an adapter a viable option? Figuring this out got me confused, so thanks for chiming in on this topic!

Hi ,
I would do the following:
Connect an adapter cable that has one RJ45 (Power Link) connector on one end to 2 x RCA (assuming that the input of your headphone amp / Bluetooth Transmitter has two RCA inputs - one for Left and one for Right)
In the Sound Menus:
- Speaker Connections to "OTHER" for both Power Link channels. (As you said, selecting LINE will disable the volume in addition to setting the output maximum to 2.0 V RMS.)
- Create a Speaker Group with the following:
- Speaker Roles should be set to either (1) Front Left and Front Right if you are using True Image in the Spatial Processing of the Sound Mode OR (2) Mix Left and Mix Right if you are using 1:1 in the Spatial Processing of the Sound Mode. (Personally, I would go with #1, since this will behave best). Set all other Speaker Roles (for your loudspeakers) to NONE - otherwise the system may try to Bass Manage from your headphones to the loudspeakers, which might be weird for you, and annoying for anyone else in the house.
- Set your Speaker Levels to -10 dB. This is to prevent overloading the input of your headphone amp (or BT Tx device). A typical line input can handle up to 2.0 V rms maximum. The Power Link output can drive up to 6.5 V rms. So, in order to reduce your output to a 2.0 V maximum (at Volume Step 90 with a signal at 0 dB FS), you'll need to drop the output by 10 dB. If you don't do this, then you may start clipping your headphone amp if you go above volume step 80.
- If you are using an analogue headphone amplifier, set your Speaker Distance to a minimum value (I actually don't know from memory if this is 1 m or 0 m - sorry...). If you are using a Bluetooth transmitter, you might want to play with this value. Increasing it will make the TV think that it has to send the sound out earlier to compensate for a more distant loudspeaker. If your Bluetooth Tx/Rx system has a latency problem, you can use the Speaker Distance to tweak the pre-delay of the audio output to compensate.
That should do it. Anything else can be adjusted to taste (i.e. Frequency Tilt, Sound Enhance, Loudness, Bass, Treble, etc...)
If this doesn't make sense, or doesn't work, please give me a shout and descibe the problem - I'll try to help you sort it out.
KMA:It's also nice to understand more of the Powerlink to RCA (or to 3.5mm minijack) connection in general, e.g. the voltage and how to handle it. Thank you for taking the time for such detailed instructions!
Note that some "line" inputs cant even handle 2.0 V RMS. So, you'll need to attenuate the output (using Speaker Level) even more to prevent clipping due to overloading the input.
If you have the spec's for the downstream device's maximum input level, you can calculate this yourself using the following equation
speaker_level_in_dB = 20 * log10( max_input_voltage / 6.5 )
The "6.5" in the equation is the maximum output level of the Power Link output - in case you're wondering.
For example:
max_input_level -> speaker_level_in_dB
2.0 V rms -> -10.2 dB
1.0 V rms -> -16.3 dB
If you don't have a calculator lying around with "log10" on it, Google works too. For example, just paste 20*log10(2/6.5) into Google and you get your answer. (beware not to use "log" on a calculator - that's usually not "log base 10" but "log base e", which will give you the wrong answer.

I knew you wanted to - I do it myself on my V1.
I use the Line-out version, because I have a small volumen controlled headphone-amp for driving the H6.
I use it almost exclusively for listening to music from my Squeezebox, which is connected to the V1 via the spdif-in.
This source is configured to pass the sound 1:1 and has the new Speaker Group, that I created, as it's default group.
(Means that I just have to turn on the head-amp, when I take it from the stand - and push the source button on the remote.)
If I want to listen to my other sources (Spotify, AirPlay, tv or a movie), I - of course - have to change the Speaker Group manually.
Listening to other sources is an option, that I do want to have - otherweise I could have connected the head-amp
directly to the Squeezebox 😉
And I use my Squeezebox with the speakers of the V1 too once in a while.
But I do wonder, who else use a headphone on their BV???
Ah, you know... A little B&O here, a little there
I'd like to pay attention - but I am not sure I understand, what you mean.
Why should I?
You can (basicly) play anything from the BV on the system using the converter.
I see!
Might be a little tricky to control for the average B&O user - (and the tv has to stay turned on).
Perhaps investing in an AirPortExpress or in a Playmaker for the Aux of the ML-system would be more convenient *
Not a 'poorman's' method - but if someone has had the money to buy a newer BV, there might be a few bucks left in the pocket for the 'right' solution.
*Provided that some kind of iDevice is at hand - of course.
Hi Geoff,
Thanks for the clear and detailed advice regarding the TV menu settings. I'm in touch with KMA via email to sort out the cabling to get everything working for him. We get a lot of people asking to connect headphones to V1, Beovision 11 and Avant, as this is becoming increasingly popular.
Either a wired connection or a link via a bluetooth transmitter is possible (I'm actually quite pleased that the headphone socket was missed off these TVs, as it means that I sell plenty of headphone cables!)
Kind regards, Steve

Everything is up and running now: a Speaker Group called "Headphones" which outputs the sound of BV11 to a wireless bluetooth transmitter and to bluetooth headphones, simply by selecting the speaker group.
The configuration:
1) I am using this cable from Sounds Heavenly to connect the BT transmitter to BV11:
http://soundsheavenly.com/bang-olufsen/65--rj45-2rca-.html
+ a RCA to 3,5mm minijack adapter that connects to the BT transmitter's 3.5mm input.
2) The RJ45 end of the cable is connected to PL4 socket on the BV11.
3) From the BV11's sound settings menus:
4) I am using this bluetooth transmitter:
http://www.avantree.com/product-bluetooth-audio-transmitter-avantree-priva-985.html
I can recommend the Avantree Priva for two main reasons, and these are important: it has AptX for high quality sound and it is a low latency BT transmitter.
Of course the BT headphones need to support AptX, and preferably also Low Latency BT.
Using a transmitter that does not support Low Latency would result in audio that is not in sync with the picture on the TV. Also, it is important to set the Speaker Distance for the transmitter connection to 0 meters from BV11's settings: even a setting of 4.0 meters results in an audio delay that makes for example speech out of sync with the picture.
With this setup, with the BT transmitter hidden out of sight, nothing gives away that there is a bluetooth transmitter connected to BV11. I find this solution very tidy & handy: simply put on the headphones, switch speaker group to Headphones, and enjoy wireless, private audio.
For headphones, I am currently using AKG Y45BT. They have an okay sound for the inexpensive price. Now that I know the bluetooth setup works with BV11, I'll be upgrading to BeoPlay H8 – once I either come to terms with the brown leather (argh) or a black edition is released by B&O
About the speaker settings and volume control (for Geoff & Steve, especially):
I did not go for the speaker type "Other" in the Speaker Connections menu as I originally suggested, which would have allowed volume control using BeoRemote One for the headphones, since I found a peculiar issue:
If the speakers are set to "Other", and the Speaker Level set to -10db as Geoff recommended for a (variable) Line output, I noticed that the volume on BV11 needed to be turned really high, to 70-90, to get even a modest sound from the headphones. Turning up the Speaker Level to 0 db or even +6 db didn't give proper sound from the headphones. At times there was no sound from the headphones (for example in quiet parts of a TV show) with these settings.
The same happened with wired headphones (EarSet 3i), so connecting wired headphones to BV11 using Speaker Groups and the powerlink outputs is not a viable option as far as I can tell. I also tried a RJ45 to 3.5mm headphone cable from Sounds Heavenly with the same results.
I wonder why "Other" and Speaker Level -10 db and "Line" (which also sets the Speaker Level to -10 db by default) are not the same sound outputs on the BV11? Only the Line output produces a proper volume for headphones (note: for wired headphones, the volume cannot be controlled). Thankfully the bluetooth headphones have their own volume control buttons for adjusting volume, so using LINE the setup works beautifully.
KMA - thanks for the details
I have used a similar setup with my V1 and a small headphone-amp for more than a year now.
I bought the cable at my local B&O dealer - no problem.
The guys in Struer already had though of situations like ours and had the cable at hand.
P.S. Looking forward to read Geoff's explanation on the 'Other' versus 'Line' issue.
Millemissen: KMA - thanks for the details ... MM

I hope this will inspire some Beoworlders to use their H8 headphones with their Beovision
Raeuber:Never heard of such hard work to connect a headphone to a television. It seems to be the 'new simplicity' of using a B&O product. It's a shame, realy unbelievable! Normal customers will have to order a technician to connect their headphones. Interisting info for an expert, though. Räuber

Now tell me, Räuber - how often do you use a headphone on your beloved BV7?
And besides - being able to create a new speakers group for this purpose is excellent for tweaking the sound settings for this group to your own needs.
This depends on the BV model:
Connecting wired headphones to – for example – BV11 with the quick access panel (not available on the latest model though) is as simple as plugging them in. Using them (via Mute!) is another matter and it could be simpler.
Connecting bluetooth headphones is trickier, as no Beovision has built-in bluetooth transmitter (does any television have it?), and I wanted to go the Speaker Group route, instead of having wires/transmitter hanging from the quick access panel.
But you have a point, especially for Beovisions such as V1 and BV11 Mk IV, which don't have a headphone out. For those, even wired headphones require some extra wires (and possibly a headphone amp), and of course the correct settings. So a technician could indeed be needed.
Millemissen:Now tell me, Räuber - how often do you use a headphone on your beloved BV7?
Raeuber: Millemissen: Now tell me, Räuber - how often do you use a headphone on your beloved BV7? Never, because I have no headphone. But some custumers wish to connect their headphone easy. I still can't understand why B&O sorted out the top panel on BV 11. I would need the HDMI port to connect a camera sometimes without laying on the floor. Regards Räuber

That was just my point!
Personally - with all the BV7-owners I have come across - I haven't met a single one, who used a headphone.
Most of them wouldn't even know, where to connect it!
One guy (with hearing damages) had the need for some kind of heedphone system (I do not know much about how these works).
I had to connect it through one of the Scart (outputs) to get it working.
No wonder B&O saw no need for a headphone-out on the newer BV's.
On my V1 there is no 'top panel' - never was.
As I installed it, I ran an extra HDMI and a USB extension cable along with the other cables to the BRP/ATV.
These are now accessable right next to the BRP.
I have never had to be 'laying on the floor', when I needed these connections.

KMA: Speaker distance: 0m (this reduces latency to minimum, so the picture and audio are in sync).
If you want to reduce the latency to minimum, then you should set the distance to maximum. This "forces" the DSP to compensate for a very distant loudspeaker by sending the signal out earlier.
KMA:I wonder why "Other" and Speaker Level -10 db and "Line" (which also sets the Speaker Level to -10 db by default) are not the same sound outputs on the BV11? Only the Line output produces a proper volume for headphones (note: for wired headphones, the volume cannot be controlled). Thankfully the bluetooth headphones have their own volume control buttons for adjusting volume, so using LINE the setup works beautifully.
Setting the Speaker Type to "Line" sets the maximum output level to 2.0 V RMS, which is approximately 10 dB below the Power Link maximum output of 6.5 V RMS. It also disables the Volume control on that output and makes it a fixed level. This is equivalent to setting the Speaker Type to "Other" (or any BeoLab speaker other than 1, 5, or 9) and putting the volume to 80 and leaving it there. (80 because that's 10 dB below maximum...)
Of course, depending on the sensitivity of the device you're connecting to, then one of these will work.
Thanks Geoff
I have the same bluetooth receiver and BV11 I have tried both ways of setting it up as mentioned by you.
I also find that the line output- solution works best like mentioned by KMA.
The Avantree Priva has aptX low latency support, is this also supported by Beoplay H8 (I know aptX is but what about LL).
Thanks
Right now I am using it with a pair of XTZ devine bout from Kickstarter, I did change th speaker distance to maximum 10 meters and have very close to no lip sync.
Ramasjang: I also find that the line output- solution works best like mentioned by KMA.
This is great to know! Originally we added the LINE option for people who wanted a simple stereo output to (for example) a stereo preamp in another room. To be honest, we didn't think of BT transmitters back when we added this to the BV11 software. However, it's great to hear that the concept holds for this usage case. I'm a little worried of cases where the transmitter can't handle a 2 V RMS input - but that depends entirely on the spec's of the device itself. Plus, you can alway use the Speaker Level menu for the output to trim accordingly.
cheers
