Hi Fabio,Output impedance has nothing to do H/L switch , only linked to the headphone jack.The 3.5mm is 30Ω.The 6.35mm is 10Ω.Thank you.

Thanks a lot for your quick answer. Still don't understand, it says in the description: "0dB/9dB/18dB gain switch. High/Low impedance switch." What does H/L switch do?
