In Reply to: RE: Optical out is what goes to my HT receiver.... posted by mark.korda@myfairpoint.net on October 24, 2016 at 21:32:16:
My sister had an elcheapo TV that had no audio outputs. Also, newer cable boxes do not have variable audio outputs so hooking that up to the vintage Pioneer and Bose would not work. I got Ma hooked up by literally connecting the speaker wires from her Toshiba CRT direct view to a set of RCA plugs.
However this is not a good idea on newer sets because they usually use a class D audio output and have no filters. The speakers in the TV act as the filters because they are inductive.
We wanted the remote to work the volume control. It was simply not possible. Connecting to the speakers would have beat on the tweeters as well as the amp.
If you don't need the volume controlled by the remote then there should be an output somewhere, like the cable box. But from what I have see of TV and movies these days they are simply unwatchable without at least a mute button. (I can't even tell what half of these frikken commercials are for !) And the commercials may not be louder on a peak level meter but they are on an averaging or RMS meter. So not having volume and mute on the remote is not an option for many.
What's more, the speakers on these flat TVs are so shitty you can't even understand the words. Little 2 X 3 things that are like what they put in laptop PCs. I know there are a few laptops out there that have almost bearable sound but they are the exception, not the rule.
So if you have the optical output on the receiver and an optical input on the HT receiver/amp go for it. You just have to juggle two remotes.
You know they used to make learn remotes you could program off the originals, they would actually record the signal. However that technology is apparently too advanced for the designers now. Obviously because they make more money that way.
Everything I have except for my computers is over 20 years old and there is a very good reason for that. It is because I know technology, it has been my job for forty years and I have seen the changes and I KNOW what they're doing. And I resent it. I will not support them to the extent of one thin dime.
Every TV should have a full complement of inputs and outputs. Maybe not optical because I think HDMI has that beat, but to not even have a variable audio output ?
And I know why. For cheapness the manufacturer used an output chip with a built in volume control that is addressed digitally. Those class D jobs. I have tried. I have tried to reverse engineer this shit and found that the way they make it, it is not possible. The signal you want is simply not there. I have been all through the datasheets on the chips used and that is how it is. I have redesigned and modified countless things over the years and they are winning, they are making it impossible.
Lately, the only thing I buy new is food. Well beer too, but just sayin'. I don't want anything, I do not have nor want a smartphone. Or iPad or Pod. When I need a new disk for the Man cave in the garage I will burn it. I will not buy a car made after 1990.
All this shit is junk, and made to ONLY do what it does. Nothing can be repurposed or anything. And I mean they do this on purpose. They are not getting any of my money. If I need something I will go to Craigslist and get it used, and I am not afraid to meet people because I have a .38 that was made on 1911, among other firearms. But that thing is not traceable to anyone, let alone me. I can leave them in a pool of blood and slowly walk away.
Nothing new. You think you're getting more ? Well if you are you are paying for it. Twenty grand for a preamp and then two grand for a phono preamp. Then let's not even go into the power amp and speakers. You can get high quality but it will cost you a fortune.
but then if you think about it, in 1975 for example, you could get a nice, really nice system for about a grand. but cars weren't even ten grand yet, most of them anyway, some people still paid cash for a house. People still paid cash for new cars, and now they put the gasoline on a credit card.
And they think that an all in one system from Best Buy is as good as an old Marantz or whatever ?
Don't sweat that TV too much, when it breaks it is junk. there will be no parts available for it and very few people could even troubleshoot it to board level, let alone component level. And many of the components require a very costly "rework" station to replace and no business wants to buy them. Look up "BGA" when it comes to ICs and then look what it takes to replace one - if you can get it.
I like my old stuff.
