Karl Winkler  joins us to talk about the evolution of wireless microphone systems through the years, how he was on the product development team for the noted Neuman KMS 105 microphone, and much more. Having spent most of his 25-plus year career working with manufacturers and currently a vice president with Lectrosonics, he gets to see a different side of professional audio and shares a lot of interesting observations.Karl’s also one of the most prolific writers in pro audio, having contributed dozens of articles to ProSoundWeb and Live Sound International magazine alone (located here) in addition to other publications. Be sure to check out his entire PSW archive, and don’t miss his latest contribution, “Showing The Way: The Power Of Positive Thinking (& Acting).”Devoted to education and mentoring, Karl continues to focus on teaching best practices regarding the “people side” of the business as well as more technical aspects such as setting wireless mic transmitter gain properly — here’s the video:The Signal To Noise podcast series on ProSoundWeb, sponsored by Shure and hosted by Live Sound/PSW technical editor Michael Lawrence and pro audio veterans Kyle Chirnside / Chris Leonard (the hosts utilize Shure SM7B mics for the podcasts).
