AES68-2014, XL Connectors to Improve EMC

 AES68-2014, AES standard for audio connectors - XL Connectors to Improve Electromagnetic Compatibility, has been published.

This standard specifies a variant of the standard XLR connector that provides improved shell-to-shell connection to aid the rejection of RF interference. While maintaining compatibility with existing XLR connectors, a circumferential connection between the connector shells is added. 

AES standards are available to AES members free of charge as a benefit of membership. Details of AES membership can be found at: http://www.aes.org/membership/

To obtain a copy of this standard, go to http://www.aes.org/publications/standards/ and search using "AES68", or go directly to:

New project - Loudspeaker driver comparison chambers

New project AES-X223, Loudspeaker driver comparison chambers, has been initiated and assigned to working group SC-04-03.

This new project will consider factors affecting the interchangeability of measurement data from simple loudspeaker comparison chambers.

In the manufacture of loudspeaker drivers, a frequent final test places each driver into a relatively-compact test chamber, measures its acoustic response to a set of test signals, and compares them with stored values derived from a reference sample. This does not provide the full performance measurements that would require a full-sized anechoic chamber, however it can identify deviations from the expected performance set by the reference.

Such test chambers are typically built only to meet local needs. As a result, the figures derived from one cannot be compared with figures derived from another.

This report will set out some relevant issues and suggest designs and construction methods to achieve measurement figures that will be comparable between different testing sites.

Here is a list of newly-created projects:
