Using the 'SPL Meter' App was great fun. If you have an iphone, this App works with it as well. It knows what hardware that it is working on & applies the right mic correction. Well worth The $0.99.

I had a typo the last 'back' reading - it should have been 11 o'clock vise 10.

I talked to Brent ref my purchase. He said that I was lucky to have come across an EP-400 on the factory clearance as they are quite rare - that's why I jumped on it. Brent has one in his own system & loves it...
