Shure MX412D/C, Gooseneck table condenser microphone@+The Microflex miniature gooseneck microphones are permanently polarized condenser microphones offering a high degree of flexibility through freely adjustable goosenecks and exchangeable condenser capsules with different directional characteristics. The cardioid (C), supercardioid (S) and omnidirectional (O) capsules are easy to change and, with their wide transmission range, provide precise sound reproduction in a variety of applications, be it in churches, courtrooms or conference rooms. The condenser capsules also go with any mic in the Microflex line for even greater comfort and consistent sound quality.@+@+ Microflex gooseneck microphones are available in four different model variants and in different lengths and mounting options. Four models have a mute button with LED indicator.
