If your existing DC power plug is not 5.5mm*2.1mm, there is no The problem is because we have included a DC conversion plug in the product. 【Protection function】ZK-MT21 Bluetooth power amplifier board has multiple protection mechanisms to ensure its safe operation. It has short-circuit protection, over-current, over-heat, and anti-reverse protection. When an overload occurs, the device reports the fault condition to the processor to protect itself from damage TIP: adequate output power is required when the audio input is sufficient and the power supply voltage/current is sufficient, the relative power will be higher. Different impedance of the speaker will have different output power.In the case of sufficient voltage and current, the larger the impedance of speaker, the smaller the relative sound power, please pay attention!
