Hi Keith, Thanks for setting up this thread, which should become a useful resource for anyone wanting to get the best from Beosound Theatre. Please add to it if you have knowledge to share! I will start by confirming that the Theatre has a USB-C input for stereo analogue audio. By using this adapter and a suitable cable, any audio source can be played through the Theatre (and also to any connected speakers):- https://soundsheavenly.com/tv-misc/191-usb-c-audio-input-adapter-for-beosound-theatre-ref-6271374.html By adding a suitable cable (available at https://soundsheavenly.com), any audio source can be connected, including Beosound music systems, Beogram turntables, music streamers, open-reel tape decks, as well as many other devices. To enable the Line input on the Theatre, please open the B&O app, select the Theatre from the list of products and go to "Source List". Choose "Line Input" and set the input type to "Music". Go back to "Sound Settings" and turn on "Auto Sense" for the line input, with the sensitivity set to Medium. If you are connecting a music source that has its own volume control (eg. the Powerlink output of a Beosound 9000) then please set the volume of the music source to around 50-75% to give normal control from the Theatre remote. Hope this is helpful! Kind regards, Steve.

On a different aspect of the Theatre, it is worth noting that any brand of TV can be used. However, full integration (with control via a B&O remote) is gained by using the recommended LG G2 panels. The 55", 65" and 77" G series panels are the officially recommended options, but the 83" and even 97" G2 panels will also work seamlessly with the Theatre. As these are too large for the B&O brackets, these larger panels should be wall mounted independently from the Theatre, instead of using the B&O wall or floor mounts. HDMI and Ethernet cables are included with the Theatre to link to the TV panel. However, when wall mounting a larger TV separately from the Theatre, a longer HDMI 2.1 and Ethernet cable may be needed:- HDMI 2.1: https://soundsheavenly.com/tv-input/55-180-premium-braided-hdmi-earc-21-cable-with-ethernet-for-8k-full-hd-and-beosound-stage.html#/4-length-3m Ethernet: https://soundsheavenly.com/powerlink-rj45-cat5-connection-models-from-2013/28-2264-rj45-powerlink-compatible-shielded-cable-for-beolab-speakers-2013-and-newer.html#/3-length-2m/18-colour-black The Theatre has a four port Ethernet Hub, so only one cable is needed to your internet router and the Theatre can then distribute wired Ethernet connections to your TV and video sources. Any Beolab speakers (right back to the original Beolab Penta in 1986) can be connected to the four stereo RJ45 Powerlink sockets of the Theatre. WiSA wireless Powerlink options are also available for compatible Beolab speakers (up to 8 wired speakers and 8 wireless speakers can be connected in total). The Theatre has the acoustic performance of all Beolab speakers (plus Beovox 1 and 2) encoded internally, so it can intelligently share bass between all the speakers that are connected, according to their capabilities. Speakers that have a "Free/Wall/Corner" switch for bass level should generally be set to "Free" when connected to the Theatre, as this gives a flat frequency response to allow the Theatre to manage their bass capabilities to best advantage. The exception to this is Beolab Penta, which gives a flat bass response when set to "Wall" (mid switch position). As the Theatre carries out room compensation on all connected speakers, they will actually perform better when used with the Theatre than they do on their own. The Theatre also has the magnitude response and phase response of all Beolab speakers coded into its software (ie. the performance of the speakers again frequency and time), so that any design quirks in the speakers will be corrected when they are played from the Theatre. This correction also applies when using a conventional music system to play to the speakers via the USB-C audio input of the Theatre. As the Theatre only has four RJ45 speaker sockets, RH45 to Powerlink splitters can be helpful to allow for the maximum eight wired speaker connections:- https://soundsheavenly.com/bang-olufsen/27-313-rj45-powerlink-compatible-splitter-new-powerlink-to-two-8-pin-din-powerlink-compatible-sockets.html#/20-length-02m Hope this is helpful! Kind regards, Steve.

Hi Beoworlders, The Technical Sound Guide for Beosound Theatre has just been published by B&O, many thanks to Geoff Martin for his work on this document and for making us aware of it. You can access this via the link below by scrolling to the "Additions" section at the foot of the page (the document may be updated over time, so this link will always point you to the latest version of the guide):- https://support.bang-olufsen.com/hc/en-us/articles/4955893911569 Kind regards, Steve.

Hi I’m considering the Theatre. Just wondering, when the threatre is wall mounted on the included bracket how far does it reach out from the wall? The depth of the Theatre is 15.7 cm I get that. In the videos above it looks like the wall installation adds quite a few cm’s.  

Late to answer you, but technical info: Wall bracket is available for 55" and 65" only.  Distance from wall to front of wings is 13.1 cm, distance to front of soundbar is 19.2 cm.  One thing not shown in the technical drawings is that the bracket lines up with the wings, but at the bottom edge, the rear panel hangs down slightly lower than the front panel, leading to a sort of "chamfered edge" effect, very nice detail. All dimensions are available from: https://www.bang-olufsen.com/en/us/soundbars/beosound-theatre and scroll down; click on "Product Sheet Download".  (Your dimension is on pages 6 & 7.)
