The f90 is a cost effective, miniature clip-on condenser microphone for drum and percussion applications. The f90 is intended for rehearsal bands, small clubs, schools and Houses of Worship. The f90 has a uniformly controlled cardioid polar pattern and provides a rich, full sound at distances of 3 to 4" off the drum head. The f90 is lightweight, compact and simple to use. The flexible gooseneck, paired with the 90-degree angle of the microphone head, allows the f90 to be positioned directly over the sound source. The f90 operates on phantom voltage of 9-52 V.
