TPA3116 High Power 2.1 Overweight Subwoofer Digital Amplifier Board 12-24V Finished Board with BT 5.0

 

 

Description:

- This is a DC single power supply 12-24V power supply, using TI's TPA3116D2 high-performance digital power amplifier chip as the core, one for parallel bridge connection bass channel power amplification output, one for left and right channel power amplification output. Can support 100W (bass channel) + 50W (left channel) + 50W (right channel) three-channel output.

- Support BT audio reception, external audio source input interface, with pre-amplifier, bass frequency division processing; bass volume, bass frequency, left and right channel volume, treble, function control switch / total volume, 5 adjustment potentiometers.

- Wide operating voltage, power-saving design, efficiency up to more than 90%. You can use a switching power supply with good performance, a laptop switching power supply, you can also use a rechargeable bottle, or a car power supply, etc...

- The board is a finished board that has been welded and tested. Connect the speaker box according to the figure, connect the appropriate power supply, connect the BT audio device to play, or correctly connect the audio source input, then it can be used.

 

Parameters:
-Dimensions: 101 (W) x 100 (D) x (H) <30mm, excluding the potentiometer and socket protrusions

-Operating voltage range: DC 12-24V (current 3-4A, or 19-24V/4-5A, if the power requirement is higher than 20-24V/8-9A)
If an alternating current (AC) transformer power supply is used, it must be rectified and filtered to be converted to a direct current (DC) power supply before it can be used. Note that the DC no-load voltage should not be greater than 25.5V (this is very important)

-BT receiving distance: >8 m (meter), version 5.0
Barrier-free objects block the receiving distance, and the BT performance of the phone itself also affects the receiving distance.

 

-Audio input sensitivity: 600-800mV, frequency response range: 20Hz-20KHz

 

-Speaker impedance: left and right channels: 4-8 ohms, bass channels: 2-8 ohms
