TPA3116 100W Subwoofer Amplifier Board Home Theater Mini Amp TPA3116D2 Audio Power Amplifiers DC12-24V
Product description: 1. This is a bass power amplifier board with preamplifier, bass crossover, and bass volume potentiometer control. It is for the pros who already have 2.0 amplifiers, and the DIY combination is used for 2.1 amplifiers. 2. It is based on TI`sTPA3116D2high performance digital power amplifier chip. 3. Use DC power supply12-24Vpower supply, wide working voltage, power-saving design, efficiency up to 90%. Supports up to 100W (Bass) bass channel output. 4. You can use a good performance switching power adapter, notebook switching power supply, or rectified and filtered transformer power supply, you can also use a rechargeable source, or car power supply, etc... 5. Boot anti-shock protection design, there is no popping at boot, please pay attention to the high requirements. 6. The board is a finished board that has been soldered and tested. Connect the speaker according to the picture, and input it with audio input and power.
Technical Parameters: Board Size: 55 X 83 X 29mm (excluding the protrusion of the potentiometer 15mm) Operating voltage range: DC9-25V (current 2-3A or more, if the power is larger, it is recommended to be 19-24V4A or more) Frequency response range: Input: 20Hz-20KHz Output: 20Hz-180Hz Audio input sensitivity: 500mV Subwoofer impedance: 2-8 ohm Color: as shown Material: ABS Note: 1. Output power and power supply voltage, speaker impedance, and audio source input size. Usually the power supply voltage is higher and the supported output power will be larger. 2. Speakers with different impedances can support different output powers. Usually, the power of the speakers is smaller and easier to achieve.
Package Contents: 1 x Subwoofer Amplifier Board
Only the above package content, other products are not included. Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
