Shop for a preamp for that jack. There are way too many for me to pick one.
I have a Vizio LED TV whose only analogue audio out jack is a 1/8" jack labeled "headphones." What I want to do is connect this jack to my Marantz integrated amp. The amp is analogue only and has the standard RCA jacks.
So I got a Y adapter cable with a 1/8" plug to two RCA plugs. Connecting the 1/8" plug to the headphone jack on my TV and the RCA plugs to the aux in jacks on my amp does get TV sound coming out of the amp. But here is the problem. To get a decent volume level I have to turn the amp way up. But then to listen to other components connected to the amp I have to turn the amp down again otherwise it is too loud. I guess the impedances do not match.
What I want to do is to somehow set it up so that I can toggle through the different components connected to the amp without having to adjust the volume every time.
I have tried adjusting the TV audio to either fixed or variable from the TV's settings menu. Neither setting seems to help. I still need to have the amp turned up loud.
So what I think I need is a headphone amp placed between the TV and the amp but I can't seem to find the right one. It would need to have analogue inputs and outputs.
Can anyone recommend a headphone amp which would serve my purpose or might there be something else I can do to fix this? I am not rich so I need something fairly inexpensive.
Thanks a lot for your help.
