Safety Instructions and Warnings:
Power Supply: Use a stable DC power supply within the range of 12-24V. Avoid using unstable or higher voltage supplies to prevent damage to the board. Do not connect to a 24V battery pack, as it may exceed the module’s voltage tolerance.
Speaker Compatibility: Ensure connected speakers have an impedance of 4-8 Ohms. Incorrect impedance can lead to distortion or damage.
Heat Management: Place the amplifier in a well-ventilated area. Avoid enclosing the module in tight spaces without proper cooling.
Wiring and Connection: Double-check all wiring connections before powering the module. Incorrect connections may result in short circuits or failure.
Volume Settings: Avoid setting the volume at maximum for extended periods to prevent overheating. Gradually increase the volume to avoid sudden power surges.
Environment: Operate in a dry, dust-free environment. Avoid exposure to water or high humidity.
Handling: Handle the board carefully to prevent damage to components or solder joints. When soldering an external antenna, follow the welding guidelines provided in the manual (page 5).
