Unboxing & Initial Hardware Inspection Checklist
Before plugging in your new Fosi Audio BT20A Pro 300W x2 Bluetooth 5.0 Home Audio Stereo Amplifier, verify the following steps:
Step 1: Inspect Physical Connectors & Cables
Ensure all connection ports are clean and free of packaging debris. Use high-quality certified cables to prevent signal degradation or power loss.
Step 2: Optimal Physical Placement & Airflow
Position the device in a well-ventilated spot. Avoid placing it in closed cabinets or directly against heat sources to prevent premature thermal throttling.
