A VU (Volume Unit) meter is used in audio equipment to measure and visualize the strength of an audio signal.

1. Signal level measurement: The VU meter shows the average strength of the audio signal. This helps engineers and operators assess whether the signal is at an appropriate level, avoiding both too low and too high audio levels.

2. Distortion prevention: By using a VU meter, operators can ensure that the audio signal does not exceed certain levels, preventing distortion that can degrade sound quality.

3. Audio balancing: The VU meter helps maintain balanced sound between different sources or channels. This is especially important when working with multi-channel audio recordings or live performances.

4. Sound quality control: Using a VU meter ensures consistent sound quality during recordings or live broadcasts.

5. Visual representation: The VU meter provides a clear and visual way to monitor the audio signal, allowing operators to quickly notice and adjust potential changes in audio levels.

For regular users, a VU meter can be an attractive accessory for audio equipment.
