Description
The product contains M1250B miniature condenser microphone with cardioid or hypercardioid polar pattern capsule, 24-inch carbon fiber boom, clutch assembly and cable.
M1250B Miniaturized Condenser Microphone with RFI Immunity
The M1250B condenser microphone has a fully integrated preamp and detachable cable providing immunity from RF interference caused by cell phones and GSM devices. The M1250B is equipped with a cardioid capsule and is available with hypercardioid capsule as well for use in live, studio and broadcast applications. The M1250B is designed to mic acoustic instruments, overhead stages, podiums, conferences and presentations.
Polar Patterns
Cardioid
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. For acoustic instruments, in general, the working range will depend on the sound pressure levels produced by the instrument. Because of its small size, the M1250B can also be used in hard to reach areas, such as beneath a cymbal. For orchestral instruments, the M1250B 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.
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.

24-Inch Carbon Fiber Boom
The boom is a carbon fiber rod compatible with any of The Micros™. Lightweight, able to attach to any microphone stand, the MicroBoom(tm), is a problem solver for many hard-to-reach miking applications including choir, live theater and orchestra.
The MicroBoom™ can be used with any of the microphones in The Micros™ series providing a broad selection of pick-up patterns, output levels and frequency responses. A high quality shielded cable is used internally to insure the cleanest audio signal path between the microphone and the bottom of the boom. The stand adapter offers total control over the angle, rotation and position of the carbon fiber rod by way of a flexible metal gooseneck. The MicroBoom™ provides an ultra-clean, professional and elegant appearance on stage while providing exceptional performance and portability.
