So I bought an LG 50" LED TV, and I wanted to output its audio to a cheap-o brand amplifier to have quality sound.
So what I did is I connected the TV headphone's output directly into the amplifier's RCA line-in inputs... and it works... but with an ugly background hum ... it's a low level hum, but it's easily perceived, and I'd like to get rid of it.
Concerning sound systems, I ain't no over the top, demanding audiofool, but I don't like a hummy, dirty sound coming out of my amplifier either.
I'm guessing that a proper interface circuit for this sort of thing is extremely easy to do, but I have no experience in the matter. Perhaps there's a already a commercial product out there for this sort of thing, but I'm no aware of it.
Any suggestions?
- The TV has two audio outputs, one is an optical output, and the other one is for headphones.
- My cheap-o brand amplifier does not have a remote, but the TV does.
- The TV's optical output volume cannot be controlled through the TV remote, but the headphone's output volume can.
