Next task is to make up some XLR cables. I found a few metres of Gotham GAC-3 in my junk store and so set about an evening of soldering up some test leads:
A quick test on the SystemOne showed them to be as good as the internal "GENMON" loopback test.
On a related note, by setting the analyser input filter to 22Hz-22kHz it reads down to 0.00034% THD+N. Awesome!
