<p>[QUOTE="Lee, post: 1829, member: 301"]Good question, Jay. There is a very tiny amount but it's really barely discernable (sp?) . That 20" Panasonic got hooked up first and the good quality video and sound on it with the Tivax is what motivated me to get going on hooking up the large TV (the one mired in all those wires inside that armoire, the one I would prefer to procrastinate on <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile :)" /> . </p><p></p><p>It wasn't until after I hooked up the large JVC TV and had the terrible hissing problem that I took the time to test for hissing on the Panasonic. I played with the volume on the Panasonic to see if it was affected too. It is affected to a very small extent. You really have to listen hard to hear the tiny background hiss and it's only there when I set the TV volume quite low and then crank up the volume using the Tivax remote, exactly the scenario in that thread I mentioned: low audio signal input. Still on that tv there is much more flexibility in how loud the volume on the TV can be set and still be "almost" perfectly clear at any volume using the Tivax converter. I can set it anywhere from about 35% to 85% on the TV and be fine. </p><p></p><p>By contrast, on the large JVC, anything lower than that 50% volume on the TV gives audio that is just not acceptable due to the hissing. My conclusion is that different TVs will respond differently due to how their audio is handled or processed. Of course, to really test that theory, I'd have to switch the converters and see if it was the same. I have a hunch it would be but I really don't want to switch those boxes. </p><p></p><p>Hope this can help someone else...[/QUOTE]</p><p></p>
