Testware Enables A2B Audio Test

Audio Precision, in collaboration with Mentor, supporting multichannel audio performance testing of Automotive Audio Bus (A2B) systems and components. Essentially, the 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%, 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. Combining the capabilities of Audio Precision’s APx500 audio analyzers and software, and Mentor’s A2B Analyzer System and software, developers can create a complete, closed-loop multichannel A2B audio test system.
