Line inputs are high-impedance (47kOhms) so splitting the signal and feeding the TV and receiver simultaneously is absolutely no problem. You just need a couple of RCA "Y" adapters to connect your television and Beomaster at the same time.

Merging two signals to supply a single input is a different issue.

I believe you could just as well wire them in parallel and omit the switch. The PC output is usually prepared to directly drive headphones, so two line level inputs in parallel can't anywhere near overload it. The end result may be quieter than now, but you can probably compensate by just cranking up the PC volume.

BTW always a good idea to unplug all equipment from mains before making this kind of connections. If the PC is not connected to an earthed mains socket, the chassis (= ground) will float somewhere between 0 and 230VAC, and it's easy to burn something with it - especially with RCA plugs and such that make the connection on signal before ground! The TV antenna socket can also bring in unwanted ground potentials from the neighbours' equipment...

Line signal from PC to TV and Amp

Hi all,

I have my BV8902 TV and BM 3000 receiver both hooked up to my PC to listen to/view digital media. I have the sound going through a DPDT switch, so I can switch the sound to either the TV or the receiver.

I was wondering, is this really necessary? Is it not possible to parallel/split the sound to both TV and receiver at the same time, or will this need some kind of signal buffer?
