The device draws or requires a supply that can provide a minimum of 0.5 Amps.
As long as the supply can meet or exceed that requirement it wont make any difference.
You could have a supply that can deliver 5V and 100A if you like, the device will only “pull” 0.5A regardless.
my father is an electrician, but unfortunately i didnt follow [: so as much as i understand that 0,5 A is a minimum, i cant tell how many "A"s might be harmful to the device, but ok - any 1A or 2A should do the job.
I made a quick test with a 1A external* source and the recording performance improved a lot - with win 7 i managed to get 50+ minutes 16bit / 48000 wav with no audible data loss.
thanks for the reply, you can close this one i guess.
I have a similar question. I want to use a high impedance low sensitivity headphone for UR22 MKII and I was wondering if I switch to 5V input can I drive that type of headphones such as AKG K701 or Beyerdynamic DT 990 Pro?
