Laura, set channel 1 to external, channel 2 to internal. In the Scroll down the audio menus, you will find Input Level 1 and 2. For Input 1 select MIC level. You don’t need to do anything for Input 2. At the back of the camera, click channel 1 into manual mode. Leave channel 2 in auto. Or if levels get too hot, click to manual and take it down. Push status check and the audio meters will appear, set channel 1 to -20db. Do the same for the internal mic if it starts to clip.
