The Saramonic XLavMic-C XLR Phantom Powered Lavalier Microphone is powered by 48V phantom power. The cardioid lavalier microphone is ideal for use in an interview setting, or if you're simply looking to capture speech from a single subject. Because of the cardioid polar pattern, the lavalier microphone is able to maintain adequate feedback and noise rejection. This helps to eliminate any background noise that might be around your subject. The lavalier microphone comes with a 20' cable and XLRM connector.
