Hi,

Not sure if this is the correct forum, but it is the only one I am
familiar with.

I have an old audio system, Technics SU 8022 stereo amp attached to
large quaulity technics speakers, works fine.
Have a Sony Bravia LCD TV which has an audio output socket which I use
for headphones occasionally.
Does it make sense to attempt to connect the TV's audio output to the
Technics amp to get better sound quality.

Sony TV Audio out:
500mVrms (100% modulation)
More than 1 Vrms at max volume setting
Impedance 47k ohms

Technics amp input:
Phono 2.5mV 47k ohm
Aux 150mV 27k ohm

I assume I will need some kind of voltage/impedance matching between
the two units.

Do you know if your Sony Bravia TV has Audio OUtput (RCA) jacks in the
back?

I don't know about your particular Sony model, but on the Wega that I
used to own, but traded in there was a setting in the menu for

[1] Speakers On - RCA outout off
[2] Speakers Off - Fixed Audio Output RCA jacks
[3] Speakers Off - Variable Audio Output to the RCA jacks

If you have a similar setup on your Sony, you can use the Variable
Audio Output to use the TV remote to control the volume going to the
amplifier.

You would hook up the output from the TV to the AUX on the back on the
amplifer, never use the Phono input for anything other than a
turntable.
