Precisely circumnavigate an ultra-fine thread of conduction around high-energy neodymium. Bond to an ultra-low-mass diaphragm. Calibrate the secondary port such that maximum phase cancellation occurs +/-125 degrees off axis. Precede the primary port with a multistage, anti-turbulent blast filter. Finish with non-reflective polyurethane to ensure the performer remains in primary focus. Compare this microphone to the industry standards for tone, gain before feedback and handling noise rejection. Mic clip and protective travel pouch are included. Specifications: Operating Principle: Moving coil dynamic Polar Pattern: Supercardioid Frequency Response: 40Hz to 18KHz Sensitivity: -54dBV (2.0mV) @ 1 Pa Impedance: 200 ohms
