Today I had the chance to compare a 402cc with my 402 and I noticed a significant difference in maximum audio-volume.
I found out the reason was my 402 still had fw 13.11 (because of medios) while the 402cc worked with version 15.12.
I made some tests, downgraded and upgraded both devices and compared the audiovolume:
The older firmware 13.11 has ca. 6dB more max. outputlevel than 15.12.
That means archos decreased the volume in the last version - why ?
But if you have a 402 with fw 15.12 and you want it louder - downgrade to 13.11:
You'll find the downgrader here:
