30results about How to "Reduce susceptibility to interference" patented technology

A microphone is described including a microphone housing having a microphone capsule disposed therein. The microphone is connected via a microphone cable to an audio system, and has an integrated amplifier that raises the signal output level. The integration of a preamplifier into the microphone advantageously reduces the microphone's susceptibility to interference. In contrast to conventional preamplifiers, the preamplifier does not, or not exclusively, operate as an impedance converter, but instead amplifies the output voltage. As a consequence, the signal-to-noise ratio is advantageously increased even in the presence of interference. The preamplifier can be provided with energy via a battery or accumulator mounted in the microphone, or advantageously from the audio system via additional conductors in the microphone cable.
