A2B is the digital audio bus technology developed by Analog Devices to deliver high-quality audio over an unshielded, twisted-pair wire. By distributing audio and control data together with clock and power over a single wire, A2B significantly reduces the weight of existing cable harnesses (by upwards of 75% in key applications), resulting in improved vehicle fuel efficiency.
From simulation and bench testing in early-stage development, to validation and production testing, having a closed-loop system to measure audio and dynamic signal performance over an A2B network is an integral part of incorporating the bus technology into next-generation automotive systems. By combining the capabilities of Audio Precision’s APx500 audio analyzers and software, and Mentor’s A2B Analyzer System and software, developers can easily create a complete, closed-loop multichannel A2B audio test system.
Within this test system, the Mentor analyzer platform provides straightforward A2B network configuration and simulation, as well as flexible routing, and high-fidelity audio. The APx audio analyzer delivers comprehensive, multichannel audio measurement analysis and offers a wide range of interface options, including analog, Bluetooth, digital serial (TDM) and PDM. Working as a complete system, these tools eliminate the effort required to develop, and support, in-house, custom test solutions.
