What's in the Box

1 x AIYIMA DC48V 10A GaN Power Supply Adapter (Model JYH37Z)

Note: An AC power cord is typically required and may be sold separately depending on the region.

Setup

Unpacking: Carefully remove the power supply from its packaging. Inspect for any signs of damage.
Placement: Place the power supply on a stable, flat surface with adequate ventilation. Ensure it is not covered or placed in an enclosed space that could restrict airflow.
Connect to Amplifier: Locate the DC input port on your compatible audio amplifier (e.g., AIYIMA A07, A07 MAX, A08 PRO, A70). Connect the DC output cable (5.5*2.5mm connector) from the power supply to the amplifier's DC input port. Ensure a secure connection.
Connect to AC Power: Connect a suitable AC power cord (not included) to the AC input port on the power supply. Then, plug the AC power cord into a standard wall outlet (AC110V or AC220V, the unit supports both).
Power On: Once all connections are secure, switch on the power supply (if it has a switch) and then power on your amplifier.

Maintenance

To ensure the longevity and optimal performance of your power supply, follow these maintenance guidelines:

Cleaning: Disconnect the power supply from the AC outlet before cleaning. Use a soft, dry cloth to wipe the exterior. Avoid using liquid cleaners, aerosols, or solvents.
Ventilation: Ensure that the ventilation openings on the power supply are not blocked. Proper airflow is crucial to prevent overheating.
Storage: If storing the unit for an extended period, disconnect it from power and store it in a cool, dry place away from direct sunlight and extreme temperatures.
Cable Care: Avoid bending or crimping the power cables excessively. Regularly check cables for any signs of wear or damage.

Troubleshooting

If you encounter issues with your AIYIMA DC48V 10A GaN Power Supply Adapter, refer to the following common troubleshooting steps:

Problem	Possible Cause	Solution
No power to amplifier	AC power cord not connected or loose. Wall outlet not functioning. Power supply or amplifier switch off.	Ensure AC power cord is securely plugged into both the power supply and the wall outlet. Test the wall outlet with another device. Verify both the power supply and amplifier are switched on.
Humming or noise from amplifier	Ground loop issue. Interference from other electronic devices.	Ensure all audio components are connected to the same power strip or outlet. Try isolating the power supply from other devices. Consider using a ground loop isolator if the issue persists.
Power supply feels excessively hot	Inadequate ventilation. Overload (drawing too much current).	Ensure proper airflow around the unit. Do not cover. Verify your amplifier's power requirements do not exceed the power supply's 10A rating.

If the problem persists after attempting these solutions, please contact AIYIMA customer support.
