Features1. The potentiometer adjusts the volume with a switch for easy control of the volume, making it good for DIY speakers.If it is a metal box, you need to bring out the Bluetooth antenna. 2. The copper DC connector is used to withstand high current and no heat. 3. Capacitor 470uf35V solid capacitors ensure power storage and heat dissipation, and stable power supply is a prerequisite for good sound quality. 4. Free DC head lead, compatible with the input power interface of this product, even if you do not have a DC head adapter or battery, it can be easily wired. 5. Bluetooth 5.0 version, the transmission efficiency is higher, the transmission distance is farther. Precautions for use: The power switch on the board is the standby switch. After the switch is turned off, the machine is in a low-power standby state. To completely turn off the power or unplug the DC plug on the machine for a long time.Specification1. Material: ABS plastic 2. Bluetooth version: 5.0 3. Adaptation supply voltage: 5-24V(optional 9/12/15/18/24V adapter, high power recommended high voltage) 4. Adapter speaker: 30-200W, 4 ohms - 8 ohms 5. Number of channels: Left and right stereo(stereo) 6. Bluetooth transmission distance: 15m(without occlusion) 7. Protection mechanism: Self-recovery overheat protection, self-recovery short circuit protection 8. Size: 55 x 38 x 17mm Tip: To have enough out put power if the input is sufficient and the supply voltage/current is sufficient. The power supply voltage is higher and the relative power will be larger. The speakers with different impedances will have different output power. In the case of sufficient voltage and current, the larger the ohms of the horn, the smaller the relative sound powre. Please pay attention!
