Karl Winkler at Lectrosonics provides a short yet concise examination on setting your wireless mic transmitter audio gain properly. Audio quality and range for your wireless system can be affected by the transmitter audio gain setting. In order to maximize your signal to noise ratio for the system, set your audio input gain as high as possible before limiting. Karl conducts the walk test demonstration. To recap, he says to set your gain on your Lectrosonics units, you want to look for good modulation, green LEDs and the -20 LED will blink red on the peaks. That is telling you are just bumping the limiter in the slightest bit and you are maximizing your signal to noise ration.
