I switched to unbalanced connector for easier understanding.
When I have the Amp on High Gain and max volume, the distortion starts at Windows volume 83/100. Is there a way to convert this in dBfs? (in EqualizerAPO the distortion starts at -3dB when Windows volume is 100 wich might be the value, I suppose)
I also put some test tones in there (1000, 500, 100, 20Hz) and measured the voltage on the 2 membrane contacts of the left driver. The raw AC value here is 5,0V for each test tone just before the distortion starts. My test song is around 4V (3V-4.6V) with this setting. Are these measurement of any use or do I still have to integrate the resistance in the calculation?
When I set everything to max, the AC value for test tones is 8,3V wich comes close to the advertised 8.8V. Or am I on the wrong path?
