What would cause your FM transmission audio to be distorted on voice peaks?

• A. You are using the wrong microphone
• B. You are talking too softly
• C. You are talking too loudly
• D. Your transmitter is malfunctioning

Answer: (C)

When it comes to FM transmission audio distortion, it's essential to understand how FM (Frequency Modulation) works and how audio levels affect it. Talking too loudly can lead to distortion for a couple of reasons. First, FM transmitters have a certain level of audio input that they are designed to handle without distortion. If the audio level exceeds this threshold — which can happen if you speak too loudly — the transmitter can become overloaded. This overload causes the peaks of your voice to exceed the transmitter's linear range, resulting in distortion. Moreover, loud audio can also provoke compression circuits within the transmitter, which are designed to keep a consistent output level. When the modulation exceeds the limits, instead of a clean output, it may result in clipped peaks that distort the intended signal. Additionally, proper microphone selection and adjustment are crucial, but the distortion typically results from excessive audio levels rather than the microphone type. Therefore, in the scenario of FM transmission, speaking too loudly is the main contributor to audio distortion during voice peaks.
