After reading the manual several points are still unclear. Seeking for clarifications. If I use it as USB DAC connected through USB-C: 1. Do I need power adapter to be plugged-in? 2. Can I quickly switch between headphone output and line-out? Manual suggests going to "Settings" menu which is unclear how quick it is.
The power needs to be plugged to operate the device; it doesn't take power from usb -c. The power supply is delivered with the package,
To switch between the headphone and the line out there is a menu setting through the main button (the same as the volume) which selects the desired output (left knob). it takes few seconds, I would say very fast and intuitive operation.
Yes, you’ll still need the power adapter plugged in.
The second one depends on your definition of “quickly.” If you know what you’re doing, it takes no more than 10 - 15 seconds
