Preamps, Whats the difference, Active & Passive ?


Ok, so I'm a bit uninformed when it comes to this.

Is it that an active pre has bass and trebble controlls and a passive does not?

I lurk here in audiogon and read all that I can when I have questions.As a last resort I ask a question.

Is there an encyclopedia of audio terns somewhere on the web that I can access?

Since a passive device has NO amplification, there's no possibility for tonal GAIN, so tone controls could only be "cuts", not "bossts". As such a treble-cut control in a passive design is not without slight merit.
What's an "audio tern"?
Ok, guys play "nicei" I never got out of the 4th grade; so as to not outdo my pops. It ain't Fathers Day yet, and he don't read; here.-- My spelling may be bad but my Grammar is well and feeling fine.--- From my limited understanding passive is fine; with the correct set up. Me?? I'm an "active-guy". Never tried or heard a passive set-up.
