50W*2+100W TPA3116 Bluetooth 5.0 Digital Power Amplifier Board Module 2.1 Subwoofer High Power TPA3116D2
This is a 12-24V DC single power supply, using TI's TPA3116D2 high-performance digital power amplifier chip as the core, one for the parallel bridged bass channel power amplifier output, and the other for the left and right channel power amplifier output. It can support 100W (bass channel) + 50W (left channel) + 50W (right channel) three-channel output.
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.
Wide working voltage, power saving design, efficiency as high as 90% or more. Good performance switching power supply, laptop switching power supply, rechargeable bottle, or car power supply can also be used.
The board is a finished board that has been welded and tested. Connect the speaker box according to the diagram, connect the appropriate power supply, connect the Bluetooth audio device to play, or correctly connect the audio source input, and then you can use it.
Operating voltage range: DC 12-24V (current 3-4A, or 19-24V/4-5A, if the power requirements are higher than 20-24V/8-9A)
If an alternating current (AC) transformer power supply is used, it must be converted into a direct current (DC) power supply with rectification and filtering.
It can be used. Note that the no-load voltage of direct current (DC) should not be greater than 25.5V (this is very important)
Bluetooth receiving distance: >8 m (meters), version 5.0
Obstacles obstruct the receiving distance, and the Bluetooth performance of the mobile phone itself will also affect the receiving distance.
Audio input sensitivity: 600-800mV, frequency response range: 20Hz-20KHz,
Speaker impedance: left and right channels: 4-8 ohms, bass channel: 2-8 ohms,
