HIFI szintű TPA3116 Bluetooth digitális teljesítményerősítő kártya 2.0 kétcsatornás sztereó 50Wx2 hangszóró

HIFI Level TPA3116 Bluetooth Digital Power Amplifier Board 2.0 Two-Channel Stereo 50Wx2 Speaker Audio
A high-quality power amplifier dedicated to HIFI music. TPA3116D2 is a class D power amplifier IC with very high index parameters. The highest modulation frequency can reach 1.2MHZ, and the distortion of high-power output is less than 0.1% .
With AUX and Bluetooth two audio input methods, two in one
It adopts copper DC connector and fence type terminal, which can withstand large current, does not generate heat, does not damage the wire, is easy to connect, and is not easy to short circuit;
Send the DC head wire, which can be compatible with the input power interface of this product, even if you do not have a DC head adapter or battery, you can also connect easily
Bluetooth 5.0 version, higher transmission efficiency and longer transmission distance, if it is a metal box, the Bluetooth antenna needs to be drawn out, otherwise the signal may not be received.
Tip: There will be enough output power only when the audio input is sufficient and the power supply voltage/current is sufficient. If the power supply voltage is higher, the relative power will be higher. Speakers with different impedances will have different output powers. In the case of sufficient voltage and current, the larger the ohms of the speaker, the smaller the relative sound power, please pay attention!
supply voltage:
12V -- 8 ohm speaker/12W (left channel) 12W (right channel), 4 ohm speaker/20W 20W
15V--8 ohm/18 18W, 4 ohm/greater than 30 30W
19V--8 ohm/32 32W, 4 ohm/greater than 45 45W
