Adjust the volume of HDMI, Microphone and Line in

line in volume, or HDMI video volume, and even need to mute them. ezcap Game Link with

needs. When the corresponding knob is turned fully counterclockwise, the corresponding
volume will be muted, and turned fully clockwise, the volume will be adjusted to the maximum.
EXAMPLE: You can adjust microphone volume by adjusting the microphone volume
adjustment knob. Connect the headset, speak into the microphone, and then adjust the
microphone volume knob at the same time until you feel it’s suitable. Turn the knob clockwise
to change the volume from low to high, turn it fully counterclockwise, and the microphone will
be muted.
Note: There may be differences between the volume you hear through the headset and the
volume of the actual captured video, as well as the volume of the live broadcast terminal.
Please adjust to a suitable position according to the volume of the captured video or the
