* The impedance of your headphones (measured in Ohm/Ω) has a strong influence on its actual maximum output level. In a nutshell, the higher the impedance, the lower the maximum output at the same gain level. Learn more about headphone impedance in this article.
** The S2 MK2 is designed to be used with a power supply. It offers an emergency mode which allows you to operate the device without power supply - in this case, lighting brightness and headphone levels are being reduced.
With the S2MK3, using a power supply has no effect on LED brightness and output levels.
