AOSHIKE DC12V-24V 2.1 Channel TPA3116 Subwoofer Amplifier Board High Power Bluetooth Audio Amplifier Board 2x50W+100W

Feature

1. Use TI's TPA3116D2 high-performance dual-digital power amplifier chip as the core. One chip is used as the left channel and one piece is used as the right channel. It is the full-range amplified power output.
2. DC single power 12-24V power supply, maximum support 100W (left channel) + 100W (right channel) dual channel output.
3. Wide operating voltage, power saving design, efficiency up to 90%. Can use a good switching power supply, laptop switching power supply, you can also use the charge bottle, or car power supply and so on
4. If AC power supply is used, the rectifier and filter must be switched to DC power before they can be used. Note that the DC no-load voltage should not exceed 25.5V (this is very important)
5. Board with pre-amplifier, with volume potentiometer, with 5V/120mA power output interface (Vout), only suitable for low power consumption equipment.The board is a finished board that has been soldered and tested well. Connect the speaker box as shown in the figure. Connect the sound source playback device and connect it to the power supply.

Description

Product description:
The main technical parameters:
1. Dimensions (L*W*H): 83 x 83 x 30 mm (not including the protruding part of the switch socket)
2. Operating voltage range: DC single power supply 12-24V (current 3-4A, or 19-24V/4-5A, such as high power requirements 20-24V/8-9A above)
3. Audio input sensitivity: 600-800mV
4. Frequency response range: 20Hz-20KHz
5. Speaker impedance: 2-8ohm
6. Output power:
Power Supply 12V/8 Europe Speaker >10W/4>20W/3>25W/2>30W (left and right channels same); 19V/8 >24W/4>45W/3>60W/2>75W;
24V/8 >35W/4>75W/3>95W;
This is the actual test data on the instrument. The output power is related to the supply voltage current, the speaker impedance, and the input of the audio source.
When the power supply voltage/current is sufficient, the power supply voltage is usually higher and the relative output power can be made larger.
Speakers with different impedances also have different output powers. Generally, the speakers have smaller impedance and more power.
