Sorry for the simple question, but it is a difficult thing to find the answer to via Google. I have a Presonus Inspire firewire interface, the primary inputs of which are two mic inputs and two Hi-Z inputs. Is it possible to put an external pre-amp between a mic and the mic input, and dial down the internal pre-amp? If so, is this actually an advisable method (i.e. is it worth it), or do I really need a bigger device with XLR line-ins? Thanks!

Swivel Master posted:An external preamp should output to quarter-inch anyway. So use the Hi-Z input. Most preamps I've seen have both XLR and 1/4" outs. I thought a Hi-Z input only accepted high impedance things like guitars, and would work poorly on, say, a preamplified condenser microphone? Or is the 1/4" output on a preamp a high impedance signal? The reason I want to do this - or at least am looking into whether I can do it - is so I can use a higher-quality preamp than the Presonus one. I grant that it's probably not worth it, but what I mainly want to know is whether it is acceptable to plug a preamp into a microphone input or the Hi-Z input, since the preamp outputs a line level signal, which I thought was different from a mic signal. It is really a matter of knowing the electronics behind the signal chain I suppose, of which I am fairly ignorant. At the very least, the internet tells me that "One can get distortion by plugging an XLR +4dB line level signal into an XLR microphone input", which I guess answers my question.

Great, thank you both. I guess I won't concern myself with external preamps for now - it wasn't so urgent, I just wanted to get it figured out.
