Performance and Noise Tests

Here's some postings of tests I did with an AKG C414 XLII plugged into a Peavey PV6 Mixer and on to a MacBook Pro Line-In. Everything was set to perform a good, natural sound capture.

The first test is rattling a Wall Street Journal in front of the microphone and then stop. It's cut because this test went forever.

Then I turned the Peavey off and left everything connected. So this is the natural MacBook noise floor with interconnection cables.

Then, since this is the analog input, I cranked the MacBook gain all the way up. I don't actually know what the design center for this connector is. I can find out.
