RMAA run on the Nano 2G vs Nano 1G

<< < (5/5)

julio:
I will try it out...

sigsegv0x0B:
RMAA has an audio calibration mode which automatically runs before you start the test itself, you really should calibrate the volume level to whatever RMAA normally wants using it's own Calibration signal.  On the few DAPS when driving a load even their max vol won't get you the needed -1DB.  When driving without any load right into into high impedance line-in then it was around 50% vol on the ipods.  Without any load the ipod generates perfectly flat frequency response thru the headphone port or thru the lineout.  Although ipod's lineout is just really a fixed volume output, not a more-real line out like say a Sony NW-A1000 which appears to have proper line out voltage when in lineout mode.

saratoga:
To expand on that last point, you should remember that you're only testing one configuration when you run RMAA.  A device driving a real load will behave differently.

For best results, you should try different setups.  Using a headphone jack splitter, you can put your headpones and the mic cable in at once, thereby testing how well the device is driving the headphones.  In the case of the Ipod, this gives VERY different results.
