Benefits of a Digitally Interfaced Studio Microphone

Document Thumbnail

With the introduction of a new technique of analog to digital conversion a digitally interfaced microphone could be developed retaining the full dynamic range and quality of analog micro-phones. Similar to known gain-ranging procedures, two separate conversion circuits are em-ployed. But in opposite, that critical signal switching processes are completely prevented, resulting in a very high dynamic range and proper signal processing up to maximum signal levels. Advantages and possibilities of using the new technique are shown based on an example which contains remote controllable functions, which were so far available only in the following signal processing, e.g. in a mixing console. With the introduction of the new AES 42-2001 standard defining audio signal transmission, powering, and remote control of microphones with digital output, the question arises, why this step has been taken only now and which features are advantageous for the user.
