Set the gain of the headphone amplifier. Set this according to the impedance of the connected headphones. It is recommended that this is set on the “Low” side if the headphones have low impedance and on the “High” side if they have high impedance.


Low (Default):	Set the gain of the headphone amplifier to “Low”.
Middle:	Set the gain of the headphone amplifier to “Middle”. Set this if the volume is too low at the factory default setting.
High:	Set the gain of the headphone amplifier to “High”. Set when there is insufficient volume, even when the gain setting is “Middle”.

NOTE

The headphone volume varies depending on the “HP AMP Gain” setting. Decrease the volume or mute the audio first if changing this setting while listening to audio.
