I know this is going to sound really stupid and ignorant, but what exactly does a pre-amp do and why would you want to use one? I'm really clueless and any help would be really appreciated.
It takes a very low level voltage, such as a microphone signal, and increases it to a higher voltage, such as a line level signal.
If you were to plug your microphone right into a device, such as most professional recording machines, it would not have enough voltage to get your recording levels nearly high enough. Thus, the microphone pre-amplifiers job is to boost that signal so that you can get a strong signal to the recording machine.
Anything that claims to be a microphone input will have a microphone pre-amplifier circuit in it. Mixing boards, some inputs into tape decks, and the mic input on a soundcard.
Whether these microphone pre-amplifiers are worth a crap is a whole other subjective deal..... More $$$ = better sound usually. But there is much debate on just how much you need to spend on a pre-amp to get something good, and certainly a lot of debate on what actually sounds good! Opinions run the gambit. Form your own.
Hi Ed, like the way you give advice in language
that all can understand, very informative.
I am currently using the pre-amps built into my
mixer, a Spirit Folio F1. I will eventually
be upgrading to a seperate Preamp. Any ideas
on something nice under 500 clams? I record
Violin. Thanx, David
