Description

Product name: Mini version 2x50W Bluetooth digital power amplifier board
Product model: ZK-502L
Adapted power supply voltage: 5~24V (optional 9V/12V/15V18W24V and other adapters, high power recommended high voltage)
Adapted speakers: 30W~200W, 4Ω, 8Ω
Number of channels: left and right dual channels (stereo)
Bluetooth version: 5.0
Bluetooth transmission distance: 15 meters (unobstructed)
Protection mechanism: self-recovery overheating protection, self-recovery short-circuit protection
Tip: Only when the audio input is sufficient and the power supply voltage/current is sufficient, there will be sufficient output power. The higher the power supply voltage, the higher the relative power, and speakers with different impedances will have different output powers. In the case of sufficient voltage and current, the larger the horn's ohms, the smaller the relative sound power. Please pay attention!
Power supply voltage: 12V-8 ohm speaker/12W (left channel) + 12W (right channel), 4 ohm speaker/20W+20W
15V-8 ohms/18+18W, 4 ohms/more than 30 + 30W
19V ——8 ohms/32 + 32W, 4 ohms/more than 45+45W
24V-8 ohms/38 + 38W, 4 ohms/more than 50 + 50W
The potentiometer adjusts the volume, with a switch, it is convenient to control the volume, which is very suitable for DIY speakers.
If it is a metal box, the Bluetooth antenna needs to be led out.
The copper DC connector is used, which can withstand high current and does not generate heat.
Capacitor 470uf35V solid capacitor, to ensure the power storage and heat dissipation capacity, stable and continuous power supply is a prerequisite for good sound quality.
The DC head lead wire is compatible with the input power interface of this product. Even if you don't have a DC head adapter or battery, you can easily wire 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 a low-power standby state. To completely turn off the power or unplug the DC plug on the machine if it is not used for a long time.
