1. Made of materials, durable and practical2. High power fever 2.0 Bluetooth amplifier board with high and low frequency adjustment3. High current, low magnetic loss, small parasitic capacitance, and low heat generation; The magnetic shielding mechanism has strong anti electromagnetic interference EMI performance4. Thickening the heat sink is the first step to solve the heat dissipation problem in order to the advantage of high power5. Transparent sound, fast low-frequency response, strong mid frequency texture, high frequency smoothness, and minimal lossProduct model:-3002TWorking voltage range:18-50VDC, limit 53VAdapted power supply:It is recommended to use a DC power supply with a voltage of 36-48V and a current of 10A or aboveMaximum power:single circuit 300W@50V , 4 ohm; 160W@50V , 8 ohm. The higher the voltage, the smaller the resistance, and the greater the output powerBluetooth chip: 5.3, transmission distance 10 metersInput :Bluetooth+AUX+USB drive/sound cardNumber of channels:2.0, left channel+right channelPower amplifier chip:TPA3255Protection mechanism:Input undervoltage, overheating, overcurrent, short circuit protection.No input anti reverse protection, positive and negative poles cannot be reversed!!!Type:B:Potentiometer external type 3002TColour:BlackMaterial:PlasticPackage Contents:1 * Digital Power Amplifier Board
