Soundeasy Notes and My Configuration
I am using a BEHRINGER ECM8000 mic from Parts Express A Mackie mixing board that has pre-amp (phantom power) for the mic M-audio Delta 410 Sound Card You also need to build the test probes detailed in Chapter 16. I made a new wiring diagram for RCA based cables. The third diagram down is the simplest illustration of the wiring for RCA cables. http://chadgray.info/speakers/RCAbasedtestcables2.jpg I made a super simple jig to help make measurements easier. It is just a 4 position switch that turns on a 10ohm resistor (for T/S measurements), a 20uF (two 10uF caps in parallel from Radio Shack) Non Polar capacitor to protect tweeters on SPL measurements and a straight pass through. I can't remember why I put a 470 Ohm resistor in there. Plus there are banana jacks positioned before and after the switch so you can move the probes around. http://chadgray.info/projectdetail.cfm?ProjectID=25 Make sure the sound card you buy is on the compatible list if you want to do DE (Digital Equalizer) and DF (Digital Filter) in the future. http://www.interdomain.net.au/~bodzio/ Also make sure your computer has enough CPU power. My Athalon 650 is fine for T/S and SPL measurements, but I doubt will cut it for DE and DF. From what I understand, you can use the Wallins Jig, but I have no idea how you would wire it up. Read John Kreskovsky's design guide found on the Bodzio web site. This will give you a jump start using SE. Also I found reading 'Loudspeaker Recipes' by Vance Dickason is a great way to understand what each measurement is really doing and how to build a proper crossover.
