The multi-Function Smart Knob controls microphone gain, mute, and headphone levels. Hold down the button for one second to switch between GAIN, HEADPHONE LEVEL, and BLEND modes.
GAIN mode is enabled when only the MICROPHONE LED is highlighted. This increases and decreases the microphone’s sensitivity. As you turn the knob, the LEDs will turn blue. Once adjusted, the green, yellow, and red LEDs will meter soft, medium, and loud signals, respectively.
HEADPHONE LEVEL mode is enabled when only the HEADPHONE LED is highlighted. This adjusts headphone output volume.
BLEND mode is enabled when both MICROPHONE and HEADPHONE LEDs are turned on. This adjusts the amount of computer audio versus microphone audio that is heard in the headphones.
