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.
