When using 2v vs. 4v, would the 2v source require the gain to be turned up a lot higher to have an equal output as with a 4v source? Or would the differences in gain settings be small?
I hear you just double the amount of gain because you halved the input voltage //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gifDepends on the range of settings that the amp has. If the amp accepts only .25-4V then the difference would be more than if the amp could use .25-15V (and there are amps out there that will do that). The difference in the first example would be about a 25% increase in the setting for the same power output.
