4. Setup

Follow these steps to set up your AC DC Adapter:

1. Verify Compatibility: Before connecting, confirm that your First Act guitar amplifier requires the voltage and current provided by this adapter. This information is typically found on the amplifier's power input jack or in its user manual.
2. Connect to Amplifier: Insert the barrel connector end of the adapter cord firmly into the power input jack of your First Act guitar amplifier.
3. Connect to Power Outlet: Plug the adapter's two-prong plug into a standard, grounded AC wall outlet (100-240V).
4. Power On: Once connected, you can power on your amplifier using its dedicated power switch.

5. Operation

The AC DC Adapter operates automatically once connected. It converts the AC power from your wall outlet into the DC power required by your amplifier. No user intervention is needed for its operation.

• Ensure the adapter is securely plugged into both the wall outlet and the amplifier.
• If the amplifier does not power on, check all connections and the power outlet.
• Disconnect the adapter from the wall outlet when not in use for extended periods.

6. Maintenance

To ensure the longevity and proper functioning of your adapter:

• Cleaning: Disconnect the adapter from all power sources before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
• Storage: Store the adapter in a cool, dry place when not in use. Avoid wrapping the cord too tightly around the adapter.
• Inspection: Periodically inspect the power cord and connectors for any signs of damage, fraying, or bending. If damage is observed, discontinue use and replace the adapter.

7. Troubleshooting

If you encounter issues with your adapter, try the following steps:

• No Power to Amplifier:
  • Ensure the adapter is fully plugged into a working wall outlet. Test the outlet with another device.
  • Verify the barrel connector is securely inserted into the amplifier's power jack.
  • Check the amplifier's power switch to ensure it is in the 'ON' position.
  • Confirm that the adapter's specifications (voltage, current) match your amplifier's requirements.
• Adapter Overheating:
  • Disconnect the adapter immediately.
  • Ensure there is adequate airflow around the adapter. Do not cover it.
  • Verify that the amplifier is not drawing excessive power (e.g., due to a fault in the amplifier).
• Visible Damage: If the adapter or its cord shows any signs of physical damage, discontinue use immediately and replace the unit.

If these steps do not resolve the issue, contact customer support for further assistance.
