2. Load Connection: Attach the output terminals to a speaker or headphone driver rated for 4 Ω. Use appropriate wire gauge to handle the current.
3. Grounding: Provide a solid ground reference to minimize hum and interference.
4. Enclosure: Mount the module in a dry, ventilated enclosure. If operating in harsh environments, select an IP‑rated case to complement the built‑in moisture protection.
5. Testing: Before full deployment, perform a low‑volume test to confirm correct operation and verify that the electronic fuse remains inactive under normal conditions.

Safety and Protection Features

The amplifier incorporates an electronic fuse that automatically disconnects the output when excessive current or temperature is detected. This feature protects both the module and connected speakers from damage, extending operational life and ensuring reliable performance.

Maintenance Tips

• Regular Inspection: Check for loose connections or signs of wear, especially in high‑vibration settings.
• Clean Contacts: Use a dry, lint‑free cloth to remove dust from input and output terminals.
• Avoid Over‑Voltage: Never exceed the maximum input voltage of 20 V to prevent component stress.
• Temperature Monitoring: In extreme environments, monitor ambient temperature to stay within the safe operating range.
