Infrared Link for Audio?

"> I want an audio link, to send a remote audio source to my home theater

system.

I'd prefer to simply buy, but I guess I could cobble up a link by
tearing open the headphones.

Gee, not as trivial as I though it might be (as you already found).
Most of the links seem to be RF. Generally the IR links are mono only (the
simple ones, at least).

I assume that you already tried the home theatre magazine advertisments?
Bose came up several times but not sure if that is a proprietary link.

Buy a small FM radio transmitter..

May simply do that. Hate to waste it, but I have a 2.4GHz video link,
purchased to demo a project... maybe I should just use it ;-)

I think i would hack a TOSLink fiber optic to a "broadcast" version instead.
It is digital and handles at least 5.1 already.

The creme de la creme of FM audio links is the synthesized Ramsey Kit
and a old 1" Rack tuner. Ramsey tends to have the best bandwidth and
low noise, in a pinch I have used it as a link for a outdoor show for
20K people. Audio quality is a lot better then most of the
RS/target/walmart FM transmitters, it uses a custom stereo generator
chip.

Wow! Looks nice! Is that legal? Or do I need a low-power license?

depends on the resistor you install in the output stage, as built its
part 15 compliant, and puts out a few milliwatts, which is more then
enough to saturate a good sized ranch house with say 6" of wire. Its
very vswr tolerant, so you can run it into a badly mismatched load
without blowing the output stage, and we all know that the antenna and
antenna height is what gets you range. put a 50 ohm smd resistor on
the output, put it on top of teh stereo and have just the leakage, if
your worried, the leakage will be enough

Oh, I took a look around the online catalog, the new one, the FM30 has
a dac and a pin diode attenuator to let you set the power to a minimum.
Its also about 50$ more.
