Audix M44 User manual

M44
OVERVIEW:
The M44 is a miniaturized condenser microphone with a fully integrated
preamp and detachable cable. This microphone is designed for close miking
high SPL instruments and sound effects. The M44, which is equipped with a
cardioid capsule, is also available in a hypercardioid polar pattern giving the
microphone the unique ability to be used in a wide variety of live, studio and
broadcast applications.
The M44 is available with a wide array of clips and accessories enabling the
microphone to be used for drums, percussion, high SPL musical instruments
and high SPL sound effects such as loud booms or explosions.

SPECIFICATIONS: ARCHITECTS AND ENGINEERS SPECIFICATIONS:
The microphone shall be of the condenser type with a modular threaded capsule available
in cardioid and hypercardioid polar patterns. The microphone shall have a fully integrated
preamp circuitry thereby eliminating the need for a remote preamplier. The microphone shall
operate on 18 - 52 Volts DC and the nominal output impedance shall be equal to 150 ohms
at 1 kHz. The microphone shall have a sensitivity at of 3 mV / Pa at 1 kHz. The microphone
shall have a maximum SPL level of ≥150 dB with THD of 0.5% and the microphone shall be
machined out of brass and the dimensions shall be 12 mm in diameter by 54 mm in length.
The microphone shall be the Audix M44.
OPERATION:
The M44 is a low impedance microphone and should be plugged into a “mic level” input on
your console, mixer or recording device. The M44 requires phantom power and will NOT
operate without phantom power voltage (48 Volts recommended) which is available on most
professional mic preamps and mixing devices. If phantom power is not available on your
equipment, you will have to procure a phantom power supply (such as the Audix APS2).
Avoid plugging or unplugging the microphone from a 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 M44, which is designed with extremely low sensitivity and very high sound pressure
capabilities, is ideally suited for close miking loud instruments such as drums, percussion,
brass and vocals.
Polar pattern: The M44 is offered in 2 different polar patterns to help you achieve optimum
results.
Cardioid (M44): In general, the cardioid pattern is the most widely used as it offers a good
balance between the sound of the instrument or voice within the context of the room or venue.
The cardioid pattern is also helpful with resistance to feedback. The working range will depend
on the sound pressure levels produced by the instrument, but in general the M44 can be within
1-2 inches of the sound source.
Hypercardioid (M44-HC): This pattern may be used to achieve the optimum amount of
feedback control and isolation, which can be valuable on a loud stage or where there are a
large number of open microphones.

SERVICE AND WARRANTY:
This microphone is under warranty
for a period of 3 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 M44 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.
