50" Carbon Fiber Boom with M1370BHC Cardioid Mic
The MBW Wireless MicroBoom series adds the convenience of wireless operation to 
the popular Audix MicroBoom range with performance that is indistinguishable from 
wired versions. Systems are designed to plug directly into Audix and other popular body 
pack transmitters (not included) that provide 4.5 to 5.5 volts DC power. A single 50” 
Wireless MicroBoom System easily reaches to the top of a three-tier riser and will cover 
a 20-person choir, while a single 84” system reaches to the top of a four-tier riser and 
will cover a 25-person choir. All cables needed to interface body pack transmitters and 
a newly designed MCWBOOM stand mount adapter are included. Systems are offered 
in 50 and 84 inch boom lengths with cardioid and hypercardioid capsule options. For 
customers seeking to convert existing wired MicroBoom systems to wireless, M1370B 
(cardioid) and M1370BHC (hypercardioid) may be ordered separately and include 
cables, MCWBOOM, MBWFLEX and WS1218 windscreen
OPERATION
The MBW range is a modular system designed to deploy the M1370B (cardioid) and 
M1370BHC (hypercardioid) microphone to an optimized height for sound capture or 
reinforcement of tiered choirs and musical ensembles with a boom-arm end designed 
to clip on to a wireless bodypack. The microphone attaches to the mini-XLR connector 
at the end of the gooseneck on the carbon fiber boom arm. To release and remove the 
microphone from the connector, simply push the button on the side of the mini-XLR 
and pull the microphone off. 
The boom arm is then securely attached to any mic stand via the MCWBOOM stand 
mount adapter (included). Using either the supplied 3 or 4 pin cable (whichever is 
applicable) the boom arm is then connected to a wireless body pack transmitter using 
the same push button connector described above. 
The wireless body pack may be mounted directly to the boom arm at the lower 
connector housing using the included MBWCLIP or mounted to the mic stand using 
the included MBWFLEX.
USER TIPS
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 
hypercardioid pattern is useful in acoustically reverberant spaces or when there are 
many open microphones. This pattern is helpful in further isolating the instrument or 
vocal from the rest of the instruments on stage - for example a loud sound source such 
as drums next to a choir. For area miking or group vocals, the recommended working 
distance can be between 2 - 3 feet from the sound source. For instruments, optimal 
position is between 3 – 12 inches; this may vary with instrument and room acoustics. 
The M1370B and M1370BHC are low impedance microphones designed solely for 
wireless operation. They require 4.5 V - 5.5 V DC bias power supplied by a wireless 
body pack transmitter and although standard 48 V DC phantom power voltage from an 
audio mixer or recording device will not damage the microphone, it will not pass signal.
