TV Sound Circuitry
Posted: Sun Jan 17, 2016 12:05 pm
I purchased a LG 42" TV a couple of years ago and as expected the sound quality is horrible. I was told I needed an opto coupled "sound bar" to get better audio. This just sticks in my craw, that after dropping $500 for a TV and now they want $2-300 to get decent sound out of it.
So after while of listening to this garbage sound, I decided to see if there was just a simple audio output jack buried in that jungle of rear panel connectors - nada! But there was a headphone jack that I found and tried it. Sound was still lousy. Next I connected my Hi-Fi system to it and although there was considerable improvement but it was still below the bar.
Now the big question- Does the opto coupled audio for sound bars come from the same location as the head phone audio? I am thinking if it was further upstream and taken from a purer source that maybe the sound quality would be better. My dilemma is that installing a sound bar and getting audio from the same general location as the headphones there would be no improvement. As the saying goes "Garbage in-Garbage out".
