Audio recording studios need high-quality AC power for several reasons:

1. Equipment performance: High-quality power can help to ensure that the equipment, such as microphones, mixers, and amplifiers, is operating at its optimal level. This can help to improve the quality of the final recording.

2. Avoiding downtime: High-quality power can help to reduce downtime caused by equipment failure and repair. This can help to ensure that the studio is able to meet deadlines and maintain a good reputation.

3. Protecting equipment: High-quality power can help to protect expensive equipment from damage caused by power fluctuations, voltage spikes, and other power anomalies.

4. Compliance with regulations: Many audio recording studios need to comply with industry regulations and standards, such as IEEE and IEC. High-quality power is often required to meet these standards.

5. Cost savings: High-quality power can save cost in the long run by reducing maintenance cost and prolonging equipment lifespan.

6. Safety: High-quality power can help to ensure the safety of the equipment and its users by reducing the risk of power anomalies that can cause fires or other hazards.

7. Power Quality: High-quality power can provide a consistent voltage and frequency, which can reduce the risk of noise and distortion in the final recording.

8. Data integrity: High-quality power can help to ensure that data is not lost or corrupted during recording or editing.

9. Acoustic environment: High-quality power can help to maintain a stable environment and prevent unwanted noise, that can affect the final recording.

It's important to note that the audio recording equipment is extremely sensitive to power fluctuations, therefore, a stable and clean power supply is essential for a high-quality final product. An Electrical Engineer can help to determine the specific needs and provide a solution for a high-quality power supply.
