The Padcaster unidirectional microphone is a broadcast-quality condenser mic, made to pick out specific sounds in front of it, while rejecting sounds behind it. Adjust for both loud and soft sound sources with the three position level control with stops at -10dB, 0dB and +10dB of gain, and eliminate ?rumble? using the two step high pass filter with 80hz and flat positions. The Padcaster unidirectional microphone?s integrated sturdy shock mount with cold shoe adapter and included windscreen are ideal for both indoor and outdoor conditions, either locked down on a tripod or hand-held on-the-fly. Requires a nine volt battery (Not Included). Also includes Padcaster's dual microphone/headphone cable - a simple, professional way to connect your microphone to the iPad.
