Balanced [[XLR]] digital audio connection, typically used between a [[CD transport]] and a [[DAC]].

The digital audio standard frequently called AES/EBU, officially known as AES3, is used for carrying digital audio signals between various devices. It was developed by the Audio Engineering Society (AES) and the European Broadcasting Union (EBU) and first published in 1985, later revised in 1992 and 2003. Both AES and EBU versions of the standard exist. Several different physical connectors are also defined as part of the overall group of standards. A related system, [[SPDIF]], was developed essentially as a consumer version of AES/EBU, using connectors more commonly found in the consumer market.

AES/EBU was designed primarily to support PCM encoded audio in either DAT format at 48 kHz or CD format at 44.1 kHz. No attempt was made to use a carrier able to support both rates; instead, AES/EBU allows the data to be run at any rate, and recovers the clock rate by encoding the data using biphase mark code (BMC).

The bit stream consists of 64-bit frames transmitted once per sample time. This is divided into two 32-bit subframes (or channels): A (left) and B (right). Each subframe consists of 32 time slots used to transmit individual data bits or synchronization information. 24 bits are available for audio data, of which 20 bits are normally used.

192 consecutive frames are grouped into an audio block. Certain status information is transmitted once per audio block. At the default 48 kHz sample rate, there are 250 audio blocks per second.
