OPERATION:
The D4 is a low impedance microphone and should be plugged into a “mic level” input of your
console, mixer, or recording device. Please note that your microphone does not require phantom
power and will not be effected in any way by phantom power should it be running simultaneously
while the microphone is in operation. Avoid plugging or unplugging the microphone from the PA
system unless the channel is muted or the volume of the system turned down. Failure to do so may
result in a loud “popping” noise which could seriously damage the speakers in the PA system.
USER TIPS:
The D4 has an extremely tight (hypercardioid) pick-up pattern in order to help eliminate sound
from other instruments on stage from “bleeding” into the microphone. For this reason, the D4
is exceptionally effective for drums and percussion in it’s ability to capture the sound of each
component of the kit.
Drums, hand percussion: As a general rule, the bottom of the D4 grill should be 1-2 inches above
the head of the drum and pointed towards the center. For more “ring” pull the mic back towards the
rim; for less ring and more overtones, position the mic 1-2 inches inside the rim; for more attack,
place the mic very close to the head; for more overtones and decay move the mic further away
from the head.
Guitar cabinets: The D4 can be placed within 1-2 inches off the grill cover at a 90 degree angle
pointing directly into the speaker. If the mic is placed closer to the edge of the speaker, you will
minimize the higher frequencies and get a warmer, fatter tone. To capture more highs, move the
mic closer towards the center of the speaker, but avoid the middle of the speaker.
Horns: Place the mic within 1-2 inches of the bell, especially when on a stage with drums, bass,
guitar, etc. For jazz, classical, and music where the stage volume is lower, the mic can be placed
further away for a richer, fuller sound.

SERVICE AND WARRANTY:
This microphone is under warranty for
a period of 5 years from any and all
manufacturing defects. Should your
microphone fail in any way, please
contact the Audix Service department at
503-682-6933. A Return Authorization
number is required before returning
any products.
CARE AND MAINTENANCE:
The D4 is manufactured to exacting specs with
roadworthy construction. However, the capsule
is highly sensitive and should be handled with
care. Avoid extreme temperatures and be sure
to store your microphone in the pouch provided
when not in use. Moisture of any kind can
adversely affect the sound and performance of
your microphone.
