This is the BEHRINGER TA 312S gooseneck dynamic microphone. It has a unidirectional polar pattern and connects directly to an XLR terminal. I planned to use it with a Roland JD-Xi, but I'm selling it because I've never used it except for a brief test to check its operation. Please note that this listing only includes the microphone itself. ■ Features o Professional dynamic microphone for transparent vocal projection o Ideal for studio, podium, conference, and desktop talkback microphone applications o Cardioid polar pattern minimizes background noise and feedback o Flexible gooseneck shaft for the ultimate user experience o Convenient on/off switch to mute during breaks o Ultra-high signal output to cut through the sound o Effective wind and pop noise filter included o Rugged and reliable die-cast body construction ■ Specifications o Type: Dynamic o Frequency Response: 50 Hz - 18 kHz o Impedance: 500Ω o Connector: XLR 3-pin o Polar Pattern: Cardioid o Sensitivity: -53 dB ±3 dB @ 1 kHz (1 V / Pa) o Weight: 236 g ■ Total Length: 45.5 cm
