ARCHITECT AND ENGINEER SPECIFICATIONS
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 circuit thereby eliminating the
need for a remote preamplifier module. 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 of 10 mV (C/HC), 12 mV (O), 18
mV (S) / pA at 1 kHz. The microphone shall have a maximum SPL level of 147 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 AND MAINTENANCE
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, use 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, studio monitors or headphones.
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 field as well as in the far field. It can be used on a wide
variety of acoustics instruments as well as on voice and vocal ensembles.
Cardioid: The cardioid pattern is helpful with resistance to feedback. For
percussion the M1280B should be used 1 - 2 feet above the cymbals, or because
of its small size, could also be used in hard to reach areas such 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 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.
Hypercardioid: 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: 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: The Omni pattern offers 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.
