Report of the meeting of the SC-05-02 Working Group on Audio Connectors of the SC-05 Subcommittee on Interconnections, held in London, UK 2010-05-23
The meeting was convened by AESSC vice chair J.M. Woodgate.
The agenda and the report of the previous meeting, 2009-10-10, were accepted as written.
Open projects
AES14-R: Application of connectors, part 1, XLR-type polarity and gender
Proposal to add an annex covering 'miniature XL' connectors is to be progressed. Natter will collect data from manufacturers, including details needed to prepare a detailed proposal to IEC SC48B to produce an IEC standard. Woodgate will look at the structure and text of the proposed Annex.
AES26-R: Conservation of the polarity of audio signals
No action necessary.
AES45-R: Connectors for loudspeaker-level patch panels
No action necessary.
Development projects
AES-X011: Fiber-Optic Audio Connections: Connectors and Cables Being Used and Considered for Audio
Secretariat format PWD overdue.
Note that the addition of OM-4 fibre should be postponed to the next edition, as OM-3 is only just now being introduced in the field.
AES-X105: Modified XLR-3 Connector for Digital Audio
Secretariat revised PWD to be progressed.
AES-X113: Universal female phone jack
PCFC held for modified graphic. To be progressed ASAP.
AES-X123: XL Connectors to Improve Electromagnetic Compatibility
Chair's input required for Foreword and Abstract.
AES-X130: Data Connector in a XL Connector Shell
Secretariat format PWD awaited.
AES59 (Former X183): Audio application of 25-way D-type connectors in balanced circuits
Chair to resolve one remaining issue from a very late comment, then the document can be published.
Liaisons:
There were no liaison issues.
New Projects:
Noted that SC-04-04 wishes to introduce a 19-contact connector application, for multiple microphone circuits. While no formal request has yet been made to SC-05-02, the key facts are known, so work can begin.
The connector is already standardized in the new IEC 61076-2-106, to be published later this year. The formal title of the standard is:
Connectors for electronic equipment - Product requirements - Part 2-106: Circular connectors - Detail specification for connectors m 16 x 0,75 with screw-locking and degree of protection ip40 or ip65/67
Woodgate will look at the preparation of a WD for SC-05-02, in conjunction with SC-04-04.
New Business:
There was no new business.
The next meeting will be scheduled in conjunction with the AES 129th Convention in San Francisco, CA, USA, 2010-11.
