||Boundary layer twin capsule having half cardioid polar pattern. CRM 202S-RF has a built in mechanism allowing the microphone to disappear after use simply by pressing the top downwards until it locks in place. A touch sensitive switch with Bi coloured halo is incorporated into the top of the microphone allowing On/Off switching when used with a DSP or logic controlled box. The microphone is constructed from high quality brass construction and is fitted with a phantom power adaptor accepting 9 to 48 volts DC. Impedance of 200 Ohms. The phantom power adaptor also includes filters which will eliminate all GSM frequencies from 800-1200 MHz. Supplied with 2 x 2M (6.6ft) 2 core + screen cable with open ended termination. Frequency response 50 Hz - 18 KHz +/-3dB, sensitivity -37dB ± 3dB @ 1KHz (0dB =1V/Pa), total harmonic distortion (THD) at an operating level of 125dB less than 1%.
