Optimizing Gain Structure: Eliminating Hum, Hiss, and Noise
Have you ever encountered a commercially installed sound system with a hum so loud it resembled a middle school talent show guitar amplifier? Or used a system where the audio sounded grated or robotic? These are signs of improperly set gain in an audio system, and as professionals, we must ensure systems are free from these issues.
This two-hour workshop will teach participants how to correctly set gain structure in a simplified audio system. We will define criteria to specify target system performance, ensuring consistent integration across projects. Gain will be verified electrically at key signal path points using test equipment, confirming the system's signal-to-noise ratio and total harmonic distortion meet specifications. These processes will be documented and shared. Participants will tune the system, set the gain structure, and observe the effects of various settings on performance. This hands-on workshop is essential for applying lessons to even the most complex audio systems today.
