1. Make sure that the channel where the microphone is connected has a green LED.
2. Turn the GAIN knob clockwise until you reach 20 db. This will automatically set that channel to Mic Level.
3. Once set to 20 db, turn the MAIN/MENU knob clockwise to adjust the master volume and test your mic until you hear Audio.
4. If you need more volume, just readjust the GAIN and MASTER VOLUME until you find the perfect volume for your speaker.
