BUILD IT YOURSELF
Here was my dilemma. Out of the box, TV sound is lousy.
I suppose it has to be that way, since there is little room
for a decent set of speakers in a modern flat screen TV.
When my son (who was working in a big box electronics
store) bought me one of these new digital TVs for my
birthday a few years back, I was overwhelmed with the
picture. With just a little outside UHF antenna, I was
picking up snow free/ghost free high definition pictures. I
thought it was better than the jittery 35 mm film movies at
theaters in those days (though now they are digital, too.)
So, what could I do about the sound? I had several older
stereo receivers lying around (remember the old
Sherwood, Pioneer, and Harman-Kardon boxes) and a
spare (and cheap) computer sound system that had a
separate bass box that I used with my old TV set. Any
and all of these worked great with the new TV. They
provided rich “bassy” three-dimensional sound compared
to the tinny flat audio directly out of the set.
A Volume Controller Using

Only one problem: I don’t consider myself much of a couch potato, but modern (if you consider the last 40
years) remote controls have spoiled me. My
improved sound system required repeated
trips to the set to adjust the volume as the
program demanded (dramatic music too
loud, voices too soft).
This was because a TV’s remote control
only adjusts the in-board sound, not that out
the audio ports in the back. This makes sense
for the TV manufacturer as they correctly
assume that you would want the TV speakers
to always be turned all the way down when
hooked to an exterior sound system.
I also had a 100 disc CD player plugged
into one of my ‘legacy’ receivers: a Yamaha
built before remote controls were common.
It also gave me my exercise, requiring
repeated trips to twiddle the volume control.
What I needed was a simple little box
that would work with any hand infrared
control (how many of these do you having
lying around in your house?) that could be
programed to control the audio out of the
