Description:

The subwoofer only transmits the bass, the frequency is below 80Hz, the middle and high frequencies are attenuated, the basics are only the bass, and the middle and high notes are very slight.

The digital amplifier can be used as a standard mono power amplifier board or as a subwoofer power amplifier board, with a preamplifier op amp NE5532 buffer matching.

Using the new US TI company TPA3116D2 high-performance power amplifier chip as the core, DC single power supply 12-25V wide working voltage, 100W mono subwoofer output, efficiency up to 90%. Switching power supply, laptop switching power supply, battery or car power supply, etc...

Knob left to the bottom is the shutdown state.

Supply power:DC12-25V(without power supply)

Output power:100W(subwoofer)

Color: Black

Power amplifier overall dimensions: 68.5X33X90mm (without knob and rear terminal)

The power supply of the board is very critical. The higher the voltage, the larger the current and the better the output power.

Tip:

To have enough output power if the audio input is sufficient and the supply voltage/current is sufficient. The power supply voltage is higher and the relative power will be larger. The speakers with different impedances will have different output powers. In the case of sufficient voltage and current, the larger the ohm of the speaker, the smaller the relative sound power.

Note:

For normal operation, connect the power supply port of the external power supply and the digital power amplifier first, and then connect the 220V power cable of the external power supply to the mains socket. The wrong way is to first turn on the mains interface of the external power supply, and then input the output interface of the external power supply to the digital power amplifier. Because the digital power amplifier has a filter capacitor, the capacitor is charged and discharged, and a low-voltage small spark is generated within 0.1 seconds of the contact. Although the low pressure has no effect, it is also a bad habit.
