Hope someone can help with this query. I want to fit an automatic
volume control to my TV/DVD system to even out the loud and soft peaks
and troughs (when children are in bed we have to continually fiddle
with the voulme control so we don't (a) wake them up or (b) have it so
quiet we can't hear the dialogue). There are stereo phono outputs
which I can use to play the sound through a freestanding amplifier, so
some sort of preamp with phono input/output would do the job.
However, despite extensive Web searches I haven't found anything other
than new TV sets or amplifiers with built-in AVC which would be too
big an expense. If there is something available in kit form I'm
willing to build it myself but I'd prefer an off the shelf solution.

Does anyone have any suggestions and just out of interest, is anyone
else annoyed by wildly fluctuating TV volume? I can't believe I'm the
only one.

Many thanks.
