AES-X085 Detailed Professional Microphone Specifications
No new progress
Erhard Werner described a new IEC TC100-TA20 project “Sound system equipment - Part 24: Headphones and earphones - active acoustic noise cancelling characteristics”.
Anthony Kuzub noted that the AES72 QTP connector standard should be adapted for multichannel microphones including being more specific about the options for a return path for phantom power.
