M1280B
OVERVIEW:
The M1280B, a miniaturized condenser microphone with a fully
integrated preamp and detachable cable, has complete immunity from RF
interference caused by cell phones and GSM devices. The M1280B, which
is equipped with a cardioid capsule, is also available with hypercardioid,
omni or shotgun capsules, giving the microphone the unique ability to be
used in a wide variety of live, studio and broadcast applications.
The M1280B is available with a wide array of clips and
accessories allowing the microphone to be used for drums, percussion,
musical instruments, overhead stage miking, podiums, conferences and
presentations.

FREQUENCY / POLARS:
The microphone shall be of the condenser type with a modular threaded capsule available in cardioid,
hypercardioid, omni-directional and supercardioid polar patterns. The microphone shall be protected
from RF interference. The microphone shall have a fully integrated preamp circuitry thereby eliminating
the need for a remote preamplier module. The microphone shall operate on 48 - 52 Volts DC and the
nominal output impedance shall be equal to 150 ohms at 1 kHz. The microphone shall have a sensitivity
at 1 kHz of 10.4 mV / Pa in cardioid, 9.8 mV / Pa in hypercardioid, 12 mV / Pa in omni and 18.3 mV / Pa
in supercardioid. The microphone shall have a maximum SPL level of 150 dB with THD of .5% and the
microphone shall be machined out of brass and the dimensions shall be 12 mm in diameter by 67 mm
in length. The microphone shall be the Audix M1280B.
OPERATION:
The M1280B is a low impedance microphone and should be plugged into a “mic level” input on your
console, mixer or recording device. The M1280B 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 M1280B, despite its size, has all the attributes of a world class recording microphone. Low noise
integrated electronics allows the microphone to function in the close eld as well as in the far eld. It can
be used on a wide variety of acoustics instruments as well as on voice and vocal ensembles.
Polar patterns: The M1280B is oered in 4 dierent polar patterns to help you achieve optimum results.
Cardioid (M1280B): In general, the cardioid pattern is the most widely used as it oers 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. For acoustic instruments, in general, the working
range will depend on the sound pressure levels produced by the instrument. For percussion, as an
example, the M1280B could be used 1 - 2 feet above the cymbals, or because of its small size, could
also be used in hard to reach areas auch as beneath the cymbals. For orchestral instruments, the
M1280B may be positioned anywhere from 3 - 12 inches depending on instrument and room acoustics.
For speech or singe voice the typical working distance is 8 - 10 inches. For area miking or group vocals
the working distance can be between 2 - 3 feet from the sound source (see ADX40 and MB1250B for
choir miking).
Hypercardioid (M1280B-HC): In situations where the volume is loud on stage or there are many
open microphones, this pattern is helpful in further isolating the instrument or vocal from the rest of
the instruments on stage. The microphone can be worked at ½ the distance of cardioid if necessary.
Supercardioid (M1280B-S): This polar pattern, also known as a shotgun pick up pattern, has a
longer reach and more narrow pattern than the other cardioid patterns. This pattern is best for podium
applications. It is helpful in pin-pointing hard to reach areas, especially for recording outdoors, and with
video.
Omni-Directional (M1280B-O): This pattern picks up from all directions, oering very little in the
way of isolation or feedback control. However, the Omni pattern oers the most accurate and natural
sound reproduction of all the patterns. It is ideal for recording, live broadcasts or video, where sound
reinforcement speakers are not an issue.

CARE AND MAINTENANCE:
The M1280B 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
aect the sound and performance of your microphone.
