Abstract
Systems and methods are disclosed for managing input to and output from a microphone, including adapting the microphone's response to changing polar response patterns among multiple microphone capsules, providing output via multi-colored lights to reflect the system state and operational characteristics, and sending various information to and from the microphone (such as carrying power to the microphone, digital and/or analog audio from the microphone, and data to and/or from the microphone) via a single cable.
Claims24
A system, comprising:
- a microphone array comprising a first microphone capsule and a second microphone capsule, the first and second microphone capsules being in a substantially fixed position relative to each other, and the array having two or more polar response patterns;
- and
- a digital signal processor having an automatically adjustable gain structure and configured to combine an output of each microphone capsule to produce a sound output signal;
- wherein, when the polar response pattern of the microphone array changes, the digital signal processor automatically adjusts the gain structure to compensate for the differences between the response patterns before and after the change.
A microphone system comprising a microphone capsule, a processor, a memory in communication with the processor, and one or more multi-colored lights in a common housing with the microphone capsule, each light having a plurality of programmatically selectable activation states,
- wherein the memory is encoded with programming instructions executable by the processor to change the activation state of at least one of the one or more multi-colored lights as a function of an operational characteristic of the microphone system.
A system comprising:
- a microphone having a connector;
- a cable having a first end, a second end, and multiple conductors running therebetween, the first end being attached to the connector, the second end being connected to a device, and the multiple conductors collectively carrying
- power to the microphone from the device,
- one or more audio output signals from the microphone to the device,
- first communication data from the microphone to the device, and
- second communication data from the device to the microphone.
