TPA3116D2 100W Mono Digital Amplifiers DIY for Music Home

Detailed Information About The Product:Subwoofer power amplifier board with preamplifier op amp NE5532 buffer matching.The power connector is a standard 5.5MM power jackPower supply range: DC8-25VOutput power: 100WChannel: Mono (subwoofer)To have enough output power if the audio 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 power.The power supply for the board is critical. The higher the voltage, the higher the current and the better the output power. If you only have 12V 1A, you can bring a 3-4 inch speaker. If you are 19V 5A or more, you can drive 8-10 inches.Note:First connect the power supply port of the external power supply and the digital power amplifier, and then connect the 220V power cable of the external power supply to the mains socket. The wrong way is to first turn on the mains interface of the external power supply, and then input the output interface of the external power supply to the digital power amplifier.Because the digital power amplifier has a filter capacitor, the capacitor is charged and discharged, and a low-voltage small spark is generated within 0.1 seconds of the contact. Although the low pressure has no effect, it is also a bad habit.Colour: blueMaterial: plasticSize: 70x70mmPackage Contents:1 * Audio AmplifierOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
