In audio equipment, the reason why VU (Volume Unit) meters are usually installed in pairs mainly involves the measurement and monitoring of stereo audio signals. Here are some of the main reasons to install in pairs:
1.Independence of stereo signals: Sound systems usually have left and right channels, and VU meters are used to measure the level of each channel. Installation in pairs ensures independent monitoring of each channel, as there may be differences in volume between the audio signals of the left and right channels.
2.Balance of stereo images: Paired VU meters can help the tuner or audio engineer ensure that the levels of the left and right channels are balanced. This is important to maintain the balance and consistency of the stereo image to avoid the sound shifting in the center of the listener.
3.Binaural Recording and Recording: VU tables are commonly used for binaural audio recording and environments. In this case, paired VU meters allow the user to monitor the levels of the left and right channels at the same time, ensuring that they are balanced during recording and **.
4.Level Adjustment and Control: With VU meters installed in pairs, users can make level adjustment and control more easily. This is important for precise adjustments during the mixing process to ensure consistency of the audio signal across different channels.
5.Accuracy and comparability: In audio engineering, the measurement of stereo signals requires a high degree of accuracy and comparability. By using paired VU tables, it's easier to compare the levels of the left and right channels to ensure they're consistent throughout the mix.
Overall, pair-mounted VU meters help audio engineers better monitor and adjust stereo signals to ensure optimal sound quality and balance during recording, mixing, and recording.
