AES42-R Review of AES42-2010: AES Standard for Acoustics - Digital interface for microphones
AES-42R has had editorial revisions to replace insensitive language. There was a brief discussion of continued interface with WGs working on remote control of parameters over a network link, but primarily for control of microphone preamplifiers, input channels and wireless transmitters, which are outside the scope of SC-04-04. Rich Cabot to change the intent of this project to passive from stabilized.

AES-X085 Detailed Professional Microphone Specifications
AES-X085 remains principally a vehicle for formulating AES advice to IEC for revision of the microphone standard IEC 60268-4. This is an ongoing but low intensity project.


There is no liaison work now underway. There is not a revision scheduled for IEC 60268-4 or 61938, the two standards where SC-04-04 has provided experts in the past.
