Discussion of audio amplifier power in home systems always prompts me to
relate this: I worked for a guy who was formerly a projectionist at Radio
City Music Hall in New York. He told me the sound system used amplifiers
rated at 70 watts per channel. That's a 6,000-seat theater.
He worked there a long time ago, so this not a claim of what they use
today. Use for perspective only, please.
I wonder if that was 'real watts' instead of inflated watts. I have seen
some wall wart computer speakers rated at 50 watts or so. Open them up and
inside the speaker may have 3 watts on the lable.
Same as with the listed gain of antennas for hams and especially the CB.
One antenna of modern times had a gain listed of several times more than it
should. Claimed to be the gain from one of the computer programs. It may
have been,but they were adding in a lot of ground gain and certain take off
angles.
Not sure where they were getting the gain numbers from,but he old CC 11
element 2 meter beams had a number that was way too high if you compaired it
on the air with another antenna.
If it was a long time ago, I suspect it was "real watts". Manufacturers
didn't really start inflating the wattage until the 70's or so.
Nowadays, a "100W" amplifier is probably more like 20 "real" watts.
