Hello!
 
I am planning to add a Raspberry Pi with a DAC in a Beocenter 7007. I bought the B&O pretty cheap, as it is not in a really good state (the tape player is make a strange buzzing sound).
 
I've been a lot influenced by this post here:
http://www.instructables.com/id/1979-Bang-Olufsen-Raspberry-Pi-Internet-Radio/
 
What i wish to do:

 
- Open, clean and refresh the Beocenter with a contact cleaner.
 
- Dismantel the tape player and replace it with the Raspberry Pi + DAC (Phatcat Dac) + Volumio as a new audio source to play files from my NAS or internet radios.
 
- Add a LCD display (Adafruit) and use the IR-Receiver to controll the Raspberry Pi.
 
- Bonus option: Use the existing VU-Meter to display the power out of the DAC.
 
The big question is, where should i solder the left and right (L+R) audio output from the DAC in the Beocenter? I could use the LINE IN at the back of the Beocenter but it's not an option: i tested it with an external CD player as a source and the volume/power isn't satisfactory.
 
I found the electric schematics here: http://beomanuals.com/manuals/Beocenter/Beocenter%207007/Beocenter_7007-Schematics.PDF
 
But i have no idea of where i should solder the two audio output. maybe someone could help me?
 
I'll post pics of the project. i should receive the parts in the next days.
 
greetings from switzerland :)
