Abstract: A microphone can include a capacitor capsule, an output buffer amplifier connected to the output of the capacitor capsule, and an audio limiter connected to the output of the output buffer amplifier, wherein the audio limiter limits the output level of the microphone at a threshold level. The microphone can include an adjustable output level. The microphone can include an integrated high-pass filter. The microphone can have an omnidirectional polar pattern.
Abstract: A microphone circuit includes a capacitor capsule and first and second impedance converters connected differentially to the capacitor capsule. The microphone circuit includes first and second output buffer amplifiers connected differentially to the first and second impedance converters.
Abstract: A microphone system includes a microphone and a control device external to the microphone. The microphone includes at least two capacitor capsules or one dual-sided capsule. The control device is capable of varying the polar pattern of the microphone over a two-conductor shielded cable or wirelessly. The microphone system may include an anti-rotational positioning mount for the microphone.
