Hi all, I am trying to test some projects here and don't really know if I am doing it properly. I am currently testing mic pres, but hopefully test methods for other dear is similar so this can serve as some sort of guide.
I will start by listing my current method here and hopefully some of you geniuses (genii?) can correct my mistakes.
What I am testing right now is an SSL9K pre. I am trying to do an FFT type plot. First of all, I use PT LE but don't have the necessary plugin so I downloaded Audacity to use their Analyze function. I didn't want to figure out Audacity and I didn't want to read any manuals so I recorded in PT, bounced, imported to audacity and ran the analyzer. Is this ok to do?
I shorted pins 2 and 3 of the input with with a 180R resistor and hit record (did 2 recordings, one at mid gain, one at max gain). I used a pot so I have no real exact idea what the gain is (I suppose I could measure the pot if I need to).
After analysis, at mid-gain I am getting -88dB.
At max gain I get -71dB.
Does these results sound right? Am I doing anything right/wrong?
What gain level am I supposed to test at?
Is there a standard way to do this?
Anything else I'm missing?
Thanks in advance!
