Hey all,

I'm currently trying to use the built-in speakers as external speakers which i would like to connect to my pc.
I already had a look into the service manual of the beovision 3. All I can see is that I need a -20 and + 20 volt for the amplifier-board on p58 (1.2.) and then right channel, gnd, mute (6v), left channel on p57 (1.2.3.4.)

Is it possible to use a laptop power supply with 20V output? Do I have to make sure it is a certain Ampere and Watt (Volt x ampere)

Thanks for your help!

With regards,

Michel
