Q: if only used with aux out (active speaker ) it needs to be powered?

Задавает alessandromagnaghi на 2020-12-01 13:00:35

ThomQc Yes, it needs to be powered to convert digital sound to analog (both active and passive speakers are analog). Aux out level can also be adjusted by the master volume knob. In my experience, you have to turn it to max to have a decent line level (for active speakers).
