2.0 HIFI Level TPA3116D2 Digital Power Amplifier Board

Product Information:

● At present, the TPA3116 digital power amplifier on the market is in a mess. It is all about eliminating the price war, completely ignoring the performance. The length of the radiator is shrunk, the capacitance samples low-end materials, and even sends a knob which is plated with plastic. In order to let you better experience the performance of the TPA3116, a number of super-value versions are specially pushed out, and the knob is turned off when it turns left to the bottom.

● Special note: the switch on the front panel is used to cut off the output, not the power supply. So the power light is always on. Don't be surprised. Because for this circuit, the static current is very, very small when there is no output, and there is a perfect protection circuit inside the circuit, so there is no need to connect it separately.

● Unlike those cheap digital power amplifiers sold for sale, the low cost can not play the role of TPA3116. Our key components are customized with 2-3 times of materials, both in terms of performance and price.

● The size of PCB is 75X60MM, and it is convenient to install output horn output terminal after the tail gap

● It uses the new TPA3116D2 high-performance power amplifier chip as the core, DC single power supply 8-25V wide working voltage, and can output 50W (left channel)+50W (right channel) dual-channel, with an efficiency of more than 90%. You can use switch power supply, notebook computer switch power supply, battery or car power supply, etc

● The power interface is a standard 5.5MM power socket, which is the same as most notebook power supplies

Tips:

Only when the audio input is sufficient and the power supply voltage/current is sufficient can there be sufficient 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 speaker/12W (left channel)+12W (right channel) 4 Ω speaker/20 (left channel)+20W (left channel),

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 55+55W,

Precautions For Use:

The normal operation is to connect the external power supply and the power connection port of the digital power amplifier, and then connect the 220V power line of the external power supply to 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 will be charged and discharged, and low voltage small sparks will be generated within 0.1 second of contact. Although low pressure has no effect, it is also a bad habit.

If the voltage on the hand of some users is lower than 12V, and they want to get strong power, they can add a booster board to increase the voltage, so that the power and timbre can be improved considerably
