AB  - A2B is a de-facto digital audio communication standard developed to introduce digital microphones to the car. Multiple microphone arrays can be connected to the same, daisy chained cable which carries both digital microphone signals (up to 32 channels) and phantom power. The bi-directional digital audio bus system is also found in head unit to amplifier connections. This paper explains the capabilities of A2B and how it works. It illustrates how the low latency A2B bus enables new applications like in-car communication and noise cancellation. The paper will also demonstrate how easy it is to use the A2B bus to bi-directionally transmit synchronous audio data (I2S/TDM-to-I2S/TDM) and control/status information (I2C-to-I2C) over multiple bus-nodes.
