Description
xThe product does not contain a power supply, you need to buy it separately or bring your own power supply.
The power supply matched with the board is very critical. The higher the voltage, the greater the current, and the more output power. If you only have 12V 1A, you can bring 3-4 inch speakers. If you are above 19V 5A, it is no problem to bring 8-10 inches. The power supply must be highly valued.
The board is welded and tested, and the board channel can be used. The warranty is three months.
The digital power amplifier can be used as a standard mono power amplifier board or a heavy subwoofer power amplifier board, withFront stage operational amplifier NE5532Buffer matching. Better than the TPA3116 without the front driver on the market.
The default delivery is to send a heavy subwoofer power amplifier board. If you want full frequency, you can tell us, and we will send full frequency delivery.
Turn the knob left to the bottom to turn it off.
PCB size is 75X60MM.
Weight: about 62g
Unlike TAOBAO's cheap digital power amplifiers that are sold for sale, the low cost cannot play the performance of TPA3116. Our key components are customized with 2-3 times the materials, regardless of performance or cost.
100W
Is to use the new AmericanTIThe company's TPA3116D2 high-performance power amplifier chip is the core,DC single power supply 8-25V wide working voltage, 50W (left channel) + 50W (right channel)doubleChannel output, efficiency up to 90%.Can use switching power supply, notebook computer switching power supply, battery or car power supply, etc...
Optional matching power supply:
The power interface is a standard 5.5/2 power jack, the same as most notebook power supplies
Power supply range: 12-24V
Tip: If the audio input is sufficient and the power supply voltage/current is sufficient, there will be enough output power. If the power supply voltage is higher, the relative power will be larger, and the speakers with different impedance will have different output power. If the voltage and current are sufficient, the larger the number of Europe horns, the smaller the relative sound power. Please pay attention!
Precautions for use: The normal operation is to connect the power connection port of the external power supply and the digital power amplifier first, and then connect the 220V power cord of the external power supply into the mains socket. The wrong way is to connect the mains interface of the external power supply first, 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, so that the capacitor is charged and discharged, and a low-voltage small spark is generated within 0.1 seconds of contact. Although the low voltage has no effect, it is also a bad habit.
