BAMILL Stereo power amplifierfor board 12V/24V high-power digital power module

Specifications: Product name: Bluetooth digital power amplifierfor board 50W * 2 Product model: ZK-502L Applicable power supply voltage: 5~24V (9V/12V/15V18V/24V and other adapters are optional and high voltage is recommended for high power) Adapted horn: 30W~200W 4 Ω 8 Ω Number of channels: left and right channels (stereo) Bluetooth version: 5.0 Protection mechanism: self-recovery overheat protection self-recovery short circuit protection Tip: Only when the audio input is sufficient and the power supply voltage/current is sufficient can there be enough output power. The higher the power supply voltage the higher the relative power and the horn with different impedance will have different output power. When the voltage and current are sufficient the greater the horn ohm the lower the relative sound power. Please pay attention! Power supply voltage: 12V ------ 8 Ω horn/12W (left channel)+12W (right channel) 4 Ω horn/20W+20W 15V -- - 8 Ω/18+18W 4 Ω/more than 30+30W 19V -- 8 Ω/32+32W 4 Ω/greater than 45+45W 24V -- 8 Ω/38+38W 4 Ω/more than 50+50W Specifications: The potentiometer adjusts the volume through the switch which is convenient to control the volume. It is an ideal choice for DIY speakers. If it is a metal box you need to take out the Bluetooth antenna. Copper DC connectors are used to withstand high current and no heat. Capacitor 470uf35V solid state capacitor ensures energy storage and heat dissipation and stable power supply is the premise of good sound quality The free DC lead is compatible with the input power interface of this product. Even if you do not have a DC adapter or battery you can easily connect it. The 5.0 Bluetooth version has higher transmission efficiency and longer transmission distance. Precautions for use: The power switch on the board is a standby switch. After the switch is turned off the machine is in low power standby state. Turn off the power supply completely or unplug the DC plug on the machine for a long time. Package includes: 1 * Power amplifierfor board 1 * DC line
