Features B>
1. The potentiometer adjusts the volume with a switch for easy volume control, making it good for DIY speakers. If it is a metal box, you need to take out the Bluetooth antenna.
2. Copper DC connector is used to withstand high current and no heat.
3. 470UF35V Capacitors Solid capacitors ensure power conservation and heat dissipation, and the stable power supply is a prerequisite for good sound quality.
4. Free DC head cable, 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.
Specifications B>
1. Material: ABS plastic
2. Bluetooth version: 5.0
3. Adaptation Power supply voltage: 5-24V (9/12/15/18 / 24V adapter, high-power high-voltage recommended)
4. Adapter speaker: 30-200W, 4 ohms ??? 8 ohms

6. Bluetooth transmission distance: 15m (without occlusion)
7. Protection mechanism: Self-recovery overheat protection, self-recovery short circuit protection
8. Dimensions: 55 x 38 x 17mm
Tip:
To have enough put power if the input is sufficient and the supply voltage/current is sufficient. The supply voltage is higher and the relative power will be larger. Speakers with different impedances will have different output power. In the case of sufficient voltage and current, the larger the ohm of the horn, the smaller the relative powre of the sound. Please pay attention!
Power supply voltage: 12V - 8 ohm Speaker / 12W (left channel) + 12W (right channel), 4 ohm speaker / 20W + 20W
15V - 8 Ohm / 18 + 18W, 4 ohm / above 30 + 30W
