Which statement is true about automatic mixers in audio applications?

1. They are used for speech applications, such as meetings.

2. They only work for program audio applications, such as music.

3. They can only adjust one channel at a time.

4. They require live personnel for operation.

The correct answer is: They are used for speech applications, such as meetings.

Automatic mixers are specifically designed to enhance audio during speech applications, such as meetings and conferences. They function by intelligently managing multiple microphone inputs, reducing ambient noise and feedback while ensuring clear audio for each speaker. By automatically adjusting the levels of active microphones, these mixers allow for more effective communication in environments where several people may speak at once. This is crucial in applications demanding high intelligibility and lower background noise, making them a preferred choice for speech-centric scenarios. The other choices focus on limitations or incorrect functionalities that do not apply to automatic mixers. For example, automatic mixers can effectively operate in both speech and music contexts, adjusting levels as needed for clarity and presence. They are designed to handle multiple channels simultaneously rather than just one at a time, and they do not require constant live personnel to manage their operation, as their automatic features allow them to adjust dynamically based on the audio input.
