[. . . ] High Frequency Circuit The capsule 01a RF-condenser microphone presents, contrary to low Irequency circuits, a low impedance output. [. . . ] With a given amplilier input impedance rand the -1 dS point at the lower Irequency limit Ig, the capacitor value is determinated by the lormula: C1 . : To prevent ground loops, pin 2 (circuit ground) is not connected with the , housing 01the power supply respectively the microphone. Connection to Amplifiers with Powering Facilities 11 appropriate voltage source is available in the amplilier the condenser an microphone can be powered directly. It should be so stabilised and liltered, that the unweighted noise voltage is< 10 ftV at 8 mA current consumption (Fig. Short Description These microphones are especially designed pressure transducers lor instrumentation purposes. Only the operating principle 01RF-condenser microphones allows a Irequency response to extend down to 0 Hz. [. . . ] Sy this means the large signal on the microphone cable is maintained up to just belore the amplilier, wh ich helps to increase the signal to noise ratio. [. . . ]
