Correct. There is no change in tech specs when using the external power supply. As Amir mentioned the external power input serves several purposes:
- stand-alone usage (mic preamp, DAC, etc)
- use with an iPad as audio interface
And as last resort in case bus power fails for whatever reason. Some older computers might have insufficient bus power, then the ps will help.
This will be noticable when one uses the unit to the max. 2 mics with phantom power engaged plus driving low impedance phones at max level plus setting the LEDs to max brightness (default is medium) will cause the highest power consumption.
