Hi,

As we know using the external 12V power supply we get louder headphone out and led brightness. I play in the dark places and I want to see what´s happening around so I cannot have leds too bright so for now I have aways ran it without external power supply but occasionally need little big more volume from headphone out.

Is it possible to get only the headphone out louder and not brighter leds? Please consider adjustable setting on the device for this.
