I have a pair of normal (unpowered) stereo headphones that I would like to connect to my rear projection TV without using a stereo receiver in between them. Since I can't see any headphone jack, it appears that my only option is to plug into one of the pairs of RCA jacks provided for output to a stereo receiver.
** How do I make a proper connection between these two connectors? Will the adapter off the shelf from some big name comsumer electronics store be the right thing?Since there's no way to only mute the TV's built-in speakers, if I had the choice (i.e., something off the shelf won't work), I would like the volume in the headphones to be noticeably louder than the apparent TV speaker volume under typical listening conditions. Perhaps the "adapter" could include a volume control.
My TV is a Sony KP-57WS510. The TV OUT RCA jacks are: 500 mVrms, 1 kiloohm impedance
My headphones are Sennheiser HD 535's (older version of the 555's). They are dynamic/open with a 120 ohm impedance and a sound pressure level(1 kHz, 1 Vrms) rating of 103 dB.
