Dayton audio now makes this device
http://www.parts-express.com/pe/showdet ... er=390-810Each unit comes with its own unique calibration file just like its big brother that I have, the emm6.
I`m not too familiar with iphone apps but on the android market, RTA pro Analyzer which is 5USD seems to be able to accept the calibration file.
It may not be equivalent to an Audiocontrol SA 3055 or 3056. But it will definitely be better than nothing. Some installers ears seem to not work very well these days, hopefully a cheap solution like this will help them and also prove very useful to Hobbyists like us.
Your thoughts?
