AES42
AES42 is the AES standard that defines the technology and operation of digital microphones.
A microphone that follows the AES42 standard has the A/D (Analog-to-Digital) converter and the preamplifier inside the microphone body itself. This means that the signal coming out of it is already digital.
The AES42 standard specifies all aspects of its operation:
Digital Audio: Audio is transmitted in AES3 (AES/EBU) format, sending a high-quality digital signal directly from the microphone.
Power and Control: It uses a special power supply called Digital Phantom Power (DPP) of 10 V. Ingeniously, this power supply also carries remote control and synchronization (clock) data, which are sent to the microphone.
Control Remote: Allows parameters such as polar pattern, high-pass filter, gain, and others to be adjusted remotely from a compatible interface or mixing console. In short, the AES42 creates a fully digital system where the microphone converts sound to digital format internally and can be controlled remotely, offering a pure signal and greater flexibility.
