B. Enabling Smart Headphone Amp
The Smart Headphone Amp feature automatically detects
impedance of your head-worn audio device, whether
earbuds or high-end headphones to provide optimal
audio dynamics. To enable this feature, connect your
head-worn audio device to the Line out jack on the front
panel and then go to the Realtek HD Audio 2nd output
page. Enable the Smart Headphone Amp feature. The
Headphone Power list below allows you to manually set
the level of headphone volume, preventing the volume
from being too high or too low.
To enable Smart Headphone Amp for the rear Line Out
jack, make sure to connect your head-worn audio device
to the rear Line Out/Front Speaker Out jack.
Go to the Speakers screen, the Headphone Impedance
Sensing item on the right displays the current headphone
impedance.
