Meaning if you know either two of the parameters (which you do) you can calculate the other
If you have a 100Wx2 amp and a 4 ohm speaker on each channel, you'll simply hook the voltmeter up to that channel and measure the power output.
100W x 4 = (V^2/4) x 4
Take the square root of both sides (since V is to the second power) and you get 20 Volt output. Wanted to point that out since there isn't a square root key on the keyboard Set your gain to equal 20 volts (or whatever you come up with depending on your amps power output).
