Communications and Residential Installation in audioXpress October 2020

The October 2020 edition of audioXpress is now available online and in print. This is one of the most feature-rich issues we have ever published, with a residential installation Market Update, a new article series about Analog Devices A2B, two articles about communications, including an article by Manfred Lutzky (Fraunhofer IIS) on codecs, plus a great review of the GeerFab Audio D.BOB Digital Breakout Box by Gary Galo. Plus three DIY-oriented articles and our regular expert columns on acoustics, tubes, and audio electronics.

This project is a great suggestion for a new affordable high-end 2 x 40 W Class D audio amplifier implemented with a Hardware Attached on Top (HAT) board to connect onto a Raspberry Pi Zero platform, creating a solution ideally suited for DIY audio projects. On the other hand, this is a very clever way to promote the Merus amplifiers from Infineon and get a great number of developers and enthusiasts to actual use it, get to know it, and understand its advantages in a real audio project.
