What does AG stand for?

Audio Ground

Audio ground refers to the specific ground reference point or plane within an audio circuit. Its primary purpose is to provide a stable common reference voltage for all audio signals and to minimize unwanted noise and interference. Unlike a general "digital ground" (DGND) or "power ground" (PGND), Audio Ground is meticulously designed to be as "quiet" or noise-free as possible. Engineers carefully separate audio ground from other noisy grounds to prevent digital switching noise or power supply ripple from coupling into sensitive analog audio signals. This is crucial for achieving high-fidelity sound.

Furthermore, proper Audio Grounding techniques are essential to avoid issues like hum, buzz, and other forms of electrical interference that can degrade sound quality. This often involves star grounding, ground planes, and careful routing of traces on circuit boards. The concept of AG is fundamental in the design and troubleshooting of audio amplifiers, mixers, recording equipment, and any electronic device that processes sound. It ensures that the intended audio signal remains clean and clear from unwanted electrical disturbances.
