29. PHANTOM Power Switch and Indicator - The mixer features an on-board,
48-Volt Phantom power supply to operate condenser microphones. When
the switch is engaged, the LED will illuminate indicating that phantom
power is now available at the microphone preamps.
IMPORTANT NOTE: To avoid a loud pop, be sure to turn down the master
level controls before plugging and unplugging the mic cables when the
phantom power is active. Be sure the MAIN level fader is turned all the
way down before activating the Phantom Power to prevent pops from
entering any external device connected to the mixer. Also, be sure the
Phantom Power is OFF when connecting or disconnecting microphones.
