3. Setup

The iPower2 is designed for easy integration into your existing setup. Follow these steps for proper installation:

1. Verify Voltage Compatibility: Ensure the iPower2 model you have (5V/2.5A) matches the voltage and amperage requirements of your device. Using an incorrect voltage can damage your equipment.
2. Select the Correct Adapter: Choose the appropriate DC barrel adapter or USB adapter from the included accessories that fits your device's power input. The 5V version includes specific USB adapters for devices like Raspberry Pi or Amazon Fire TV Stick.
3. Connect to Device: Plug the selected adapter into your device's power input.

4. Operating Principles

The iPower2 utilizes advanced technology to deliver clean and stable power:

• Active Noise Cancellation II: This technology actively measures and inverts the signal from your power supply, similar to noise-canceling headphones. This creates a super quiet noise floor, filtering out spurious frequencies that can interfere with audio and video signals.
• Enhanced Noise Suppression: Featuring improved components and thicker gauge wiring, the iPower2 offers superior output and input noise suppression, making it significantly quieter than many standard power supplies.
• Benefits: Expect clearer audio, more defined digital video, and overall improved performance from connected devices such as turntables, media streamers, phono stages, routers, DACs, and audio interfaces.

5. Maintenance

The iFi iPower2 is designed for reliable, long-term performance with minimal maintenance.

• Keep the unit in a dry environment, away from direct sunlight and extreme temperatures.
• Clean the exterior with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
• Ensure proper ventilation around the unit to prevent overheating.

6. Troubleshooting

If you experience issues with your audio system after installing the iPower2, consider the following:

• Hum or Buzz: If you hear a hum or buzz, it may indicate an earth loop or a missing earth connection in your audio system.
• Identifying Earth Issues: With your audio playing, carefully touch a metal surface on your audio device (e.g., USB port, metal chassis, speaker terminals, headphone sockets). If the hum or buzz changes, it suggests an earth issue.
• No Earth Connection: If touching a metal surface reduces the noise, your system may lack a proper earth connection. Consider using a 3-pin power adapter for your device or an iFi Groundhog+ (sold separately) to establish an earth connection.
• Multiple Earth Connections (Earth Loop): If touching a metal surface does not change the noise, you might have multiple earth connections creating an earth loop. To identify the source, remove cables one by one from your audio system until the hum subsides. The last cable removed before the hum stops is likely contributing to the earth loop. iFi offers products like the iDefender3.0 for USB audio connections or Ground Defender for power connections (sold separately) to address excess earth.
