TPA3116 Bluetooth 5.0 High Power 2.1 Subwoofer Digital Amplifier 12-24V

Detail TPA3116 Bluetooth 5.0 High Power 2.1 Subwoofer Digital Amplifier 12-24V

1. This is a DC-powered 12-24V power supply, with TI's TPA3116D2 high-performance digital power amplifier chip as the core, one for the power amplifier output of the bass channel connected in parallel, and one for the power amplifier output of the left and right channels. Support 100W (bass channel) + 50W (left channel) + 50W (right channel) three-channel output.



2. Support Bluetooth audio reception, external audio input interface, with preamplifier, bass crossover processing; bass volume, bass frequency, left and right channel volume, treble, function control switch/total volume, 5 adjustment potentiometers.



3. Wide working voltage, energy saving design, efficiency up to 90%. You can use a switching power supply with good performance, a laptop switching power supply, a rechargeable bottle or a car power supply, etc.



4. The board is a finished board that has been welded and tested. Connect the speaker box according to the picture, connect an appropriate power source, connect to a Bluetooth audio device for playback, or connect the sound source input correctly.



5. Bluetooth 5.0 version.



Main product parameters:



Dimensions (length * width * height): 101 x 100 x 25mm, excluding potentiometer and socket projection



Operating voltage range: DC 11-25V (current 3-4A or 19-24V / 4-5A, such as high power requirements 20-24V / 8-9A or more)



Please note that the DC no-load voltage should not be greater than 25.5V.



Bluetooth receiving distance:> 8 m (meters)



Audio input sensitivity: 600-800mV



Frequency response range: 20Hz-20KHz



Speaker impedance: left and right channel speakers: 4-8 ohms, woofer impedance: 2-8 ohms



The output power is related to the power supply voltage/current, speaker impedance and the size of the audio input. When the power supply voltage/current is sufficient, the power supply voltage is usually higher, and the relative output power can be higher. Speakers with different impedances have different output powers. Generally, the speaker impedance is smaller and the power is easier to achieve.
