Support
Bang & Olufsen does not provide support for projector and home cinema set-ups for other than BeoLiving dealers who have attended training. Therefore Bang & Olufsen only provides information on the output signals from the BeoVision 7.
However, if you have a customer who is interested in purchasing a BeoLiving or similar solution, it is recommended that you either team up with an authorised BeoLiving dealer or apply for becoming BeoLiving dealer.
Software requirements
BeoVision 7-32 and BeoVision 7-40 support projector control as from software version 6.3 and higher.
Supported projectors
The following projectors are officially supported by Bang & Olufsen: Samsung SP H700 and SIM2 HT300 PLUS (Can be found in connections menu on the BeoVision 7 family).
We have verified the performance and picture quality of these two projectors. Additionally you can connect an IR blaster directly to one of the control outputs and the built in code-converter will adapt the commands from the Beo4 to the correct projector commands.
If you connect another type of projector, Bang & Olufsen cannot guarantee the functionality and quality, but here are the specifications for the projector output.
Projector out specification
For the connection of a projector in a Home Cinema setup. Formats supported:

The projector must be connected to the ‘Projector’ socket.
Cinema Centre Speaker
The centre speaker - BeoLab 7-4 - placed under the projector screen must be connected to the Cinema Centre socket on socket panel 2.
If BeoVision 7-40 is covered by the projector screen - except from the speaker - the TV speaker is used as centre speaker. An external IR-receiver is necessary to be able to control BeoVision 7-40.
External IR-receiver
The external IR-receiver must be connected to the IR In socket on socket panel two. In order to control the switching On/Off of the projector the IR transmitter for the projector must be connected to one of the ‘IR Control Out’ sockets (C1 - C4).
Home Cinema Control module
If you want to control external equipment such as electrical curtains, lighting or a motorised projector screen it is possible to buy and build in a Home Cinema Control module. It consists of two control outputs (in one stereo mini jack connector) which you can use for controlling external equipment.
The outputs - Ctrl. 1 and Ctrl. 2 - are open collectors. An open collector is basically a switch with two positions - ‘open’ (high) and ‘closed’ (low). The outputs are therefore not able to supply power to 3rd party equipment which means that an external voltage must be supplied. The maximum external supply voltage must not exceed 15 V and the current must not exceed 100 mA.
The Home Cinema Control module can be set up to different timings (Cinema Timers) which can be found in Customer service menu Access to Customer Service Menu:
Press the "MENU" button on Beo4 to get into the "TV Set-up Menu"
Place the cursor on "Option". Press the Red button and within 3 seconds press "Go"
The available timers are:
Cinema on:
- Cinema Control 1:
The setting decides the delay time of equipment connected. When ‘Home Cinema’ is activated the output is set to ‘closed’ (low) after the delay time and the connected equipment will be activated - a motorized projector screen will pull down or a light control system will switch the light off.
- Cinema Control 2:
Performs exactly as Cinema Control 1.
- Cinema Ready:
The setting decides the delay time from the activation of ‘Home Cinema’ until the projector is warmed up and the picture is switched on.
- Stand Done:
The setting decides the delay from ‘Home Cinema’ is activated until the stand is in standby position.
Cinema Off:
- Cinema Control 1:
The setting decides the delay time of equipment connected. When ‘Home Cinema’ is activated the output is set to ‘open’ (high) after the delay time and the connected equipment will be activated - a motorized projector screen will pull up or a light control system will switch the light on.
- Cinema Control 2:
Performs exactly as Cinema Control 1.
- Ready For Cinema:
The setting (in this case 100 sec.) decides the delay from ‘Home Cinema’ is deactivated until the projector has cooled down and can be switched on again.
- Turn Stand Delay:
The setting (17 sec.) decides the delay from ‘Home Cinema’ is deactivated until the stand is turned into TV viewing position and the TV switched on.
Hope that helps let me know if it works, I still need to go to customer and see if it works
