2. Key Features
- Long-Grain Copper (LGC): Minimizes distortion caused by grain boundaries within the metal conductor, ensuring a clearer signal path.
- Semi-Solid Concentric Conductors: Strands are packed more tightly and do not change position within the bundle, significantly reducing strand-interaction distortion.
- Silver-Plated Drain Wire: Direction-controlled silver-plated shield conductors efficiently drain RF noise from the line and neutral shields to the third 'ground' pin, resulting in a powerful, dynamic, and immersive sound.
- Direction-Controlled Conductors: A fundamental aspect of AudioQuest's multi-faceted Noise-Dissipation Technology, these conductors properly dissipate and drain induced noise.
- Enhanced Audio Experience: The NRG-Y3 delivers a high-quality and superior entertainment experience by providing clean power.
- Noise-Dissipation Technology: Minimizes interference for a quieter background, allowing for greater detail and clarity in audio and video.
- High-Quality Materials and Design: Utilizes high-purity conductor metals and noise-dissipation technology to minimize distortion.
- Versatile Connectivity: An excellent upgrade for various audio/video components such as DACs, powered desktop speakers, gaming consoles, and streamers.
- Durable and Reliable Design: Built to withstand daily use and ensure consistent performance over time.

3. Setup Guide
Follow these steps to properly connect your AudioQuest NRG-Y3 power cable:
- Identify Components: Ensure your audio/video component (e.g., amplifier, DAC, streamer) has a compatible C13 power inlet.
- Power Off: Before connecting, ensure all audio/video components and the power source are turned off and unplugged from the wall outlet.
- Connect to Component: Firmly insert the C13 connector end of the NRG-Y3 cable into the power inlet of your audio/video component.
- Connect to Wall Outlet: Insert the 3-prong wall plug end of the NRG-Y3 cable into a grounded AC wall outlet or a high-quality power conditioner.
- Power On: Once both ends are securely connected, you may power on your audio/video components and enjoy the enhanced performance.
Note: Always ensure a secure connection to prevent intermittent power supply or potential damage. Avoid bending the cable sharply, especially near the connectors.
4. Operating Instructions
The AudioQuest NRG-Y3 power cable operates passively, providing a stable and low-noise power delivery to your connected devices. No specific operational steps are required beyond proper connection.
- Optimal Performance: For best results, connect the NRG-Y3 to high-quality audio/video components and a clean power source.
- Directionality: The cable is designed with direction-controlled conductors. Ensure the cable is oriented as indicated by any markings (if present) for optimal noise dissipation.
5. Care and Maintenance
To ensure the longevity and continued performance of your AudioQuest NRG-Y3 power cable, follow these maintenance guidelines:
- Cleaning: Gently wipe the cable and connectors with a soft, dry, lint-free cloth. Do not use liquid cleaners or abrasive materials.
- Storage: When not in use, store the cable in a clean, dry environment, away from extreme temperatures and direct sunlight. Avoid tightly coiling the cable.
- Handling: Always grasp the connectors when plugging or unplugging the cable. Avoid pulling on the cable itself, as this can damage the internal conductors or connections.
- Inspection: Periodically inspect the cable and connectors for any signs of wear, fraying, or damage. If damage is observed, discontinue use and contact AudioQuest support.
6. Troubleshooting
If you experience issues with your AudioQuest NRG-Y3 power cable, consider the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to device | Cable not fully seated; Wall outlet issue; Device power switch off | Ensure both ends of the cable are firmly connected. Test the wall outlet with another device. Check the device's power switch. |
| Intermittent power | Loose connection; Damaged cable | Reseat connections. Inspect the cable for visible damage. If damaged, replace the cable. |
| Humming or buzzing noise | Ground loop; External interference; Faulty component | Ensure all components are properly grounded. Check for nearby sources of electromagnetic interference. Test with another power cable to isolate the issue. |
| Cable feels warm | Normal operation (slight warmth); Overload; Poor ventilation | A slight warmth is normal. Ensure the connected device is within the cable's specifications. Provide adequate ventilation around the cable and device. |
