One week countdown...

From what I understand, it is half of a room correction. You need to take care of the other half yourself. Let me explain: you need a third-party software / hardware solution (software, PC, microphone) to analyze your listening room. The result of that analysis will show you things like 'you have a 6db dip around 500 Hz' etc. Those data points ( e.g. '+6db @ 500 Hz ) you can then plug into the 'sweet room' config of the Devialet and stick in onto your smart card with the regular config. Sp it is an equalizer but you need to know what to equalize, basically.

Hummm... it´s not a very confortable way to fix the room issues, each time you need to alter something, you change the data in the smart card, input the data, listen the result, if not right try again, etc.
