5.Phantom Power Buttons: These two buttons apply +48V phantom power to XLR inputs 1-4 and 5-8. The top button activates phantom power on XLR inputs 1 through 4 while the bottom button activates phantom power for inputs 5 through 8. The LED next to each button will illuminate when phantom power is being sent to the associated channels.

6.Headphone Level Knobs: These knobs adjust the output volume of the headphone outputs. Turn these knobs clockwise to increase the level of their associated headphone outputs; turn them counterclockwise to reduce the output levels.

About Phantom Power:

Be mindful when engaging phantom power since not all microphones require phantom power to operate. For example, most dynamic microphones do not require any phantom power whereas condenser microphones usually do. Some vintage ribbon microphones may be damaged if phantom power is applied to them. Always consult your microphone’s manual before applying phantom power.

7.Headphone Jacks: Connect headphones to these jacks. The first headphone output is sourced from audio routed to analog outputs 1/2 while the second headphone output is sourced from audio routed to analog outputs 3/4.
