INSTRUMENT / GROUP VOCAL
CONDENSER MICROPHONE
ADX50 CONDENSER MIC
overview
The ADX50 is a pre-polarized condenser
microphone designed to handle a wide
variety of live, studio and broadcast
applications. Characterized with a cardioid
pickup pattern and a smooth uniform
response over a frequency range of
40-20k Hz, the ADX50 is precision machined
from solid brass with a low reflective black
e-coat finish.
Low noise electronic circuitry, low
impedance, and balanced output allow
interference-free performance even with
long cable runs. The ADX50 is road-worthy
and capable of reproducing high sound
pressure levels of 132dB.

ADX50 may be used as a hanging mic or on a stand to pick
up group vocals for ensemble, choirs or plays. Two mics
may be positioned overhead or in front of the group, at a
distance of 4-6 feet apart.

Recording: The ADX50 can be used
effectively to record just about any acoustic
instrument. Because of the simple design
and excellent transient response, simply
point the microphone towards the sound
source making sure the mic is far enough
away to avoid distortion. In the case of
stereo miking, all the rules would apply as
they would for other small diaphragm,
cardioid condensers. (see the Audix Mic
Application Guide for examples).
Supplied Accessories
In general, when using multiple ADX50s
for live sound, they should be spaced at a
distance of at least 4-6 feet apart. Using
fewer mics can result in a more ‘spatial’
effect and provides greater chance for
greater control over feedback.

Live Sound: When miking instruments, the
ADX50 should generally not be closer than
6 inches to the sound source. In the case of
group vocals, drum overheads, bells, and
percussion toys, the microphone can be from
1-4 feet from the source. Microphone
placement is not an exact science and
depends on the instrument, the room size,
the PA system, and the musicians. Therefore,
some experimentation is usually necessary in
order to achieve the desired results.
Optional Accessories
g Mic clip (MC2) adjustable through 180
degrees with standard 5/8 inch. -27 thread.
Note: Metal stand adapter also supplied to
accommodate European standard threads.

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. For outdoor use,
consider using the foam windscreen
(WS-ADX50) to reduce wind noise or
popping. When not in use, please store your
mic in the vinyl case at room temperature.

WARNING:
The ADX50 has a fixed-charge, 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’ sensation which could
seriously damage the speakers in the PA system.
Power requirements are 9-52 volts phantom power; most current
mixing boards are equipped with phantom power, however, if
phantom power is not available please use the Audix APS-2 (2
channel) AC powered phantom supply as your interface between
the microphone and the mixing board.
OUTPUT:
It is recommended to use a high quality microphone cable with 3
pin XLR connectors. The ADX50 output is balanced across Pin 2
(positive) with respect to Pin 3, with the shield connection is
Pin 1.
SERVICE AND WARRANTY:
This microphone is warranted 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.
