For the many audioXpress readers following Brewster LaMacchia's four-part article series about “Getting Started with Analog Devices' Automotive Audio Bus (A2B),” this is the third part, focusing on solution design. After an introduction to the properties of this locally networked audio transport that has very low and deterministic latency and comparisons with existing digital audio interfaces, the series continues to look further into A2B system design, bus topology, and phantom power features. In this article, LaMacchia looks more closely at A2B data transport and how to interface between peripherals and the A2B bus using parts made by Analog Devices.

In this article for Voice Coil, Bruno Putzeys and Lars Risbo, two co-founders of Purifi Audio, share some details about the company's unique research with loudspeakers, and reveal their findings in looking for the roots of speaker nonlinearities and distortion mechanisms. These were in fact the efforts that led to the fundamental design used in Purifi's growing line of drivers, featuring many innovations including Force Factor Modulation (FFM) - optimized motors and Sd-neutral cone surround using alternating normal and inverse roll segments. A research effort that the authors believe deserves consideration from the industry, as a new set of standard parameters that should be included in datasheets.
