What is the make and model of the HDTV?
What is the make and model of your current audio receiver?
Get a receiver. It is the cheapest way to get 5.1 to the speakers. Any AVR will provide from 2 to 5.1 or more outputs.
TV is LG 42LE5350 optical only audio output Dolby 5.1
Receiver is Onkyo TX-4500
Most of the reviews from users on sites like Amazon.com say that modern AV receivers seem to have a very high infant mortality. Most likely as a consequence of being manufactured in places where quality control is minimal to non-existant. Are there any AV receivers out there that are not made in China ?
It is on the side panel and labelled H/P with a little heaphone symbol. Get an 1/8" stereo male to RCA male pair (R/L) cable and try it out connected to one of the tape (AUX) inputs of your Onkyo TX-4500.
I thought the signal level would be too high and the impedance too low.
Okay, I'll get a 1/8" TRS to RCA Phono jacks adapter and give it a try.
I'll report back.
Rolls MB35 ProMatch, Technolink TCC TC-780i, etc. But the headphone output should work, but be careful with the volume levels set on both the HDTV and the receiver. Good Luck!
"A typical headphone amp isn't much more than a line amp configured to be able to deliver higher currents into the lower impedances found in most headphones. Headphone impedance will typically range from 8 to 600 ohms, which is we now know is much lower than a line level input. A headphone amp has to be able to deliver the current necessary to drive these phones, but since the drivers are small, and right up against your ears, it doesn't take much voltage to generate the power needed to make them loud enough. If you connect a headphone signal to a several thousand ohm line level input it will behave pretty much like a line level signal. The key here is the voltage. How much voltage does your headphone amp produce? If it's less than 15 or 20 volts there is no danger of it doing any damage to a line input, and almost all headphone outputs found in typical audio gear are substantially less than this."
