The MICRO-D is a pre-polarized condenser microphone
designed for many applications including drums, percus­sion, amplified cabinets, speech, vocals and acoustic
instruments. Used in conjunction with 3 different types
of specialized clips and 2 different types of interchange­able capsules the MICRO-D becomes a modular sytem that
can fulfill a wide variety of creative needs.

With a smooth uniform response over a frequency range
of 40 Hz –20 kHz, the MICRO-D is lightweight, compact,
and extremely easy to use. Housed in an aluminum ring
and isolated by means of a rubber shock mount system,
the stock version of the Micro-D (model ADX20-d) has a
hypercardioid pick-up pattern and is capable of handling
sound pressure levels up to 140 dB.

The MICRO-D operates on phantom power of 9–52 Volts
and is supplied with a phantom power adapter, integral
Dvice clamp, cable, windscreen, and carrying pouch. Low
noise electronic circuitry and balanced low impedance
output allow for interference free performance even with
long cable runs.

Specifications are subject to change without written notice.

Operation and Maintenance:

Condenser microphones as a general rule are
much more sensitive and reactive than dynamic
microphones and should be handled with care.
Avoid extreme temperatures wherever possible.
Moisture and high humidity can adversely effect
the performance of the microphone and cause
permanent damage. When not in use, please
store your mic in the pouch or case provided at
room temperature.

Capsule replacement: The MICRO-D is designed
with a field replaceable threaded capsule. For
this reason, it is possible to carry spare capsules
to insure against the unexpected. Simply
unscrew the capsule in order to repair or replace.
Call the Audix service department direct for any
repair work.

Live Sound & Recording

Drums: The MICRO-D is designed to clip on the

rim of a drum (see photo on front page). The
provided clip (D-vice) is spring loaded. The
inside slider portion of the clip should be
attached to the bottom part of the rim first and
the clip lifted up and over the top rim for a tight
tension fit. You can adjust the position of the
gooseneck by means of the lower thumb screw
on the D-vice. The mic itself is generally posi­tioned 2-3 inches off the drum head and slightly
inside the rim pointing towards the head (see
photo on front).

Congas, hand percussion:

To attach the MICRO-D to
hand percussion, you will
need the optional D-clamp
clip. Simply remove the mic
and shockmount ring and
screw it on to the threaded
portion of the D-clamp. This clip enables you to
clamp securely on to a tension rod. The goose­neck itself is slightly longer for correct position­ing. The gooseneck may be adjusted by means of
the lower thumb screw.

Cymbal stands, mic stands:

To attach the MICRO-D to a
stand, you will need the
optional D-flex clip and the
thread adapter provided. As
you can see, the D-flex clip
has very wide jaws which
allows it to clamp on to all
types of stands or cabinets.

Vocals, overheads, guitar,
area miking: The MICRO-D

can also be used with any
standard mic stand or
boom stand by simply
using the provided thread
adapter. For these applica­tions, the cardioid capsule
is recommended because it has a much wider
pick-up pattern than the hypercardioid capsule.

WARNING:

The Micro-D has a fixed charged, permanently polarized
back plate. This, along with voltage from a phantom
power supply, causes the element to be fully charged.
For this reason,

DO NOT PLUG OR UNPLUG THE MICROPHONE
INTO OR OUT OF THE PA SYSTEM UNLESS THE VOLUME OF THE
SYSTEM IS TURNED DOWN.

Failure to do so may result in a
loud “popping” noise sensation which could seriously
damage the speakers in the PA system.

OUTPUT:

The MICRO-D output is balanced across Pin 2 (positive)
with respect to Pin 3. The shield is connected to Pin 1.
It is recommended to use a high quality microphone
cable with 3 pin XLR connectors.

SERVICE AND WARRANTY:

This microphone is under warranty for a period of 1 year 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 sending back any products.
