Access BLEND Mode by holding down the button located below the Blue logo until the HEADPHONE and MICROPHONE LEDs are both on. This adjusts the amount of computer audio versus microphone audio that is heard in the headphones.
When the meter is centered — meaning that the 12 o'clock LED is on — the computer audio and microphone audio are set to equal levels.
Set the meter towards the MICROPHONE highlighting all the LED lights from 7 o’clock to 12 o’clock. This will remove your input levels from your headphones. The input levels will still record onto your computer.
