AC Power and Interconnects for Low System Noise

Friday, Sept. 30, 2022 9:00 am – 12:00 pm at CEDIA Expo 2022 in Dallas, TX

This course will lift the veil of mystery that surrounds symptoms like hum and buzz in audio and seemingly random misbehavior in video and other digital portions of AV systems. We will explain how AC power indirectly causes these problems and what simple steps can be taken in new building construction to effectively avoid the problems altogether. For systems in existing buildings, a simple no-instruments troubleshooting method can pinpoint the causes and locations of noise problems. A variety of solution strategies and devices will be compared with respect to performance, cost, and safety. Some “solutions” actually put your customer’s life at risk and expose you to lawsuits. Of course, along the way, some myths and “wives tales” will be explained and de-bunked. Attending this course will not only make you smarter but you’ll avoid the embarrassment and expense of recalls to fix noise and elusive system “misbehavior” problems … your hard-earned reputation is at stake!
