See if the TV has a regular pair of RCA audio-output jacks, which you

use instead of the headphone jack. Regardless of which you use, there

be no need for voltage or impedance matching. (I don't know where you

your specs, but the TV does not have a 47K audio output impedance. It's
about 1/20 that.)


Thanks for your response.

I want to use the headphone jack for output because using the jack
mutes the TVs speakers and allows me to control volume using the TV
remote (the stereo amp does not have a remote).

I assume this is just a cabling problem, headphone jack male split to
RCA audio plugs.

Al.

I'd recommend trying the RCA jacks first. Most (many) have circuitry that
detects a connection and mutes the output. The headphone jack is likely
low impedance and as such won't match the amplifer as well.




Really? I've not heard of this function with an RCA socket, but I don't
deal with much domestic audio equipment.

Can you or someone post a link to how this works?


Cheers,

Not sure I've ever seen any on a TV set, but phono (RCA) sockets with built
in mechanical switches are certainly to be found on some amps. One that
comes to mind is a big Yammy AV amp that uses them for the 5.1 discreet
inputs, I think. The switches go bad resulting in intermittent or missing
channels when it is working in 'normal' mode ...
