Insert an ultra-light diaphragm into an acoustic field. Detect the pressure gradient as the membrane symbiotically oscillates. Move a coil of wire in the magnetic field. Generate an analogous electrical current in compliance with Faraday. Precisely phase align to create maximum attenuation at +/- 125 degrees. Install blast filter, mechanical decoupling, and recessed on/off switch. Apply non-reflective polyurethane. Compare to industry standards for tone, gain before feedback and handling noise rejection. Includes 15ft XLR/XLR cable and mic clip. Applications Live Vocals, Brass, Guitar Cabinets, Bass Cabinets. CAD25A Specifications Operating Principle: Moving coil dynamic Polar Pattern: Supercardioid Frequency Response: 80Hz to 13KHz Sensitivity: -53dBV (2.3mV) @ 1 Pa Impedance: 500 ohms
