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 designed to mic acoustic instruments, overhead stages, podiums, conferences and presentations. In addition to the stock cardioid model in black, the M1250B is also available with different polar patterns and colors. 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 a preference at time for podium applications. It is helpful in pin-pointing hard to reach areas, especially for recording outdoors, and with video.
