Bảng Mạch Khuếch Đại Âm Thanh Bluetooth Mini Zk-1002 Hifi 5.0 Tpa3116

100% brand new and high quality
Features:
Made of high quality materials, featuring high performance and high performance price, especially for HIFI music power amplifier with high power and high fidelity.
5.0 Bluetooth version has higher transmission efficiency, and longer transmission distance.
TPA3116D2 is a D type amplifier IC, which has very high frequency of up to 1.2MHZ, and the output distortion is less than 0.1%.
The red and gray ring inductors are specially designed for digital power amplifiers, while the 684 film capacitor is a special capacitor for audio amplifier, so both of them are features low loss, high bandwidth and high fidelity.
With AUX and bluetooth two audio source input mode, two in one.
With a switch, potentiometer can be used to adjust the volume, easy to control the volume, very suitable for DIY speakers.
Copper DC female head, fence terminal, withstand large current, no heat, no damage to the line, good wiring, not easy to short circuit.

Tip: 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. Please pay attention!
