Mic Positioning
Position the DE50x microphone element about
0.25” – 1” behind the corner of your mouth.
Since the DE50x is an omnidirectional capsule,
the end of the microphone does not need to be
facing your mouth. To avoid breath noise and
p-pops, do not place the microphone directly in
front of your mouth. If the microphone is too far away from your
mouth you will need to increase the gain and
reduce isolation.
To minimize additional noise, do not locate the
microphone tight against your cheek.
