I have version MPAA1 which is a copy of this version ... even Thomann software, same CD, even soft internal same look ... just like a beast ... copy ...

I have used 4 months ...
Spectrum analysis, dBmètre (A / C / flat), phase tester, signal generator.

quite useful as a verification tool and very comfortable decibel meter.
hair "cell food" ... but with the AC adapter has its place in-house without worry.
I used to test the systems on which I get and I do not know well ... it can get an idea of ​​the extremely fast frequency response and bandwidth systems for ... the calibrations, it's my good old: CD and it decides the ear ... it's frustrating to have before when doing a timing system with ^ ^ I have to say ... and then if not for all my decibel meter on the Taffs zic ... always on an eye on the big button to return to their rightful place ... especially at the end of benefits, with the ear fatigue was always the unfortunate tendency to growing levels ... this is a good tool.

excellent price / quality ratio in the version in which I bought ... 220 euros against 400 euros for the version of Phonic ... in exactly the same for a product, there's no photo ...
This choice I would do without hesitation.
