AES66-2012, Miniature XLR-type polarity and gender

AES66-2012, Miniature XLR-type polarity and gender

AES66-2012, AES standard for professional audio equipment - Application of connectors - Miniature XLR-type polarity and gender, has been published.

This standard is intended to apply to three- and five-pin circular connectors, commonly and generically known as miniature XLR-type, used for the balanced interconnection of all categories of sound system components for professional audio, commercial, recording, broadcast, and similar applications, regardless of function, type, or level of the signal. It specifies the application and polarity of analog signals for these connectors and is intended to avoid the inversion of absolute polarity among the items in the analog signal chain.

AES65-2012, Connector for surround microphones

AES65-2012, Connector for surround microphones

 

AES65-2012, AES standard for interconnections - Connector for surround microphones, has been published.

An increasing number of surround sound microphones are becoming available, however, there has been no common standard for the connectors between microphone and recording device. It is expected that a standard connection will create a basis for smaller and lighter recording devices. 

This standard specifies a connector type and contact assignment for microphones having up to six balanced analog output channels, as used in surround sound applications. It includes specifications for marking and identification for the audio channels. It includes recommendations for cable type and detailed wiring. It is expected that other applications will also use this connection.

AES2-2012, Measuring the performance of loudspeakers - Drive units

AES2-2012, Measuring the performance of loudspeakers - Drive units

 AES2-2012, AES standard for acoustics - Methods of measuring and specifying the performance of loudspeakers for professional applications - Drive units, has been published.

This document is a recommended practice for describing and specifying loudspeaker components used in professional audio and sound-reinforcement systems. The document considers high-frequency and low-frequency drivers and passive loudspeaker systems for professional applications, and identifies the relevant methods of measurement. Specifications are given for describing frequency response, impedance, distortion, and power handling. This document does not consider sub-components such as spiders or cones. It is intended for loudspeaker system designers, and drive-unit manufacturers. 
 
This document is a substantial revision of AES2-1984, which it supersedes.

AES-1id-2012, Plane-wave tubes - Design and practice

AES-1id-2012, Plane-wave tubes - Design and practice

AES-1id-2012, AES Information Document for Acoustics - Plane-Wave Tubes - Design and Practice, has been published

The standard AES2 calls for the use of plane-wave tube measurement of high-frequency horn drivers. Because many variations and results are possible, depending on the details of construction of plane-wave tubes, this document discusses those variations for the purpose of encouraging further experimentation.

This 2012 edition is a revision of AES 1id-1991. Additional uses of a plane-wave tube are listed. Further tests were performed to compare a distant microphone location with a close location to test the hypothesis that non-plane-wave radiation would be more accurately measured. A termination method is described. A modern method of calibration is referenced and summarized.
