Feature:
1. Three Channel Output: Using TI's TPA3116D2 high performance digital power amplifier chip as the core, one to do parallel bridged bass channel power amplification output, one to do left and right channel power amplification output. Support 100W (bass channel) + 50W (left channel) + 50W (right channel) three channel output.
2. Different Output Power: The output power is related to the supply voltage current, the speaker impedance, and the size of the audio input. When the power supply voltage current is sufficient, usually the power supply voltage is higher and the relative output power can be made larger. Usually, the speaker impedance is smaller and the power is easier to achieve.
3. External Audio Input: 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 or total volume, 5 adjustment potentiometers.
4. Wide Working Voltage: Energy saving design, efficiency up to 90%. DC powered 12‑24V power supply, you can use a good performance switching power supply, laptop switching power supply, you can also use a charging bottle, or car power supply, etc.
5. Easy To Connect: The board is a finished board that has been soldered and tested. Connect the speaker box according to the correct connection method, connect the appropriate power supply, connect to the Bluetooth audio device to play, or connect the sound source input correctly.
