- Connect your studio monitors or headphones to the output jacks.
3.4. Powering On
The Komplete Audio 6 is USB bus-powered, meaning it draws power directly from your computer via the USB cable. No external power supply is required. The power indicator LED on the top panel will illuminate when successfully connected and powered.
4. Operating the Komplete Audio 6
4.1. Input/Output Overview
The interface features two combo XLR/TRS inputs on the front for microphones and line/instrument signals, and two additional line inputs on the rear. It also provides four balanced line outputs, S/PDIF digital I/O, and MIDI I/O for comprehensive connectivity.
4.2. Gain Control
Each analog input has a dedicated gain knob to adjust the input level of your connected microphone or instrument. Monitor the input level indicators on the top panel to ensure your signal is strong but not clipping (peaking into the red).
4.3. Phantom Power (48V)
For condenser microphones, activate the +48V phantom power by pressing the corresponding button next to the input gain knob. Ensure phantom power is only used with microphones that require it.
4.4. Monitoring
The Komplete Audio 6 offers direct monitoring with zero latency. Use the Monitor knob to blend between the direct input signal and the playback from your computer. Adjust the headphone volume knobs for independent control over each headphone output.
