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's TPA3116D2 high performance digital power amplifier chip. 3. Use DC power supply 12-24V power 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. Wiring : Confirm the wiring is correct, and finally plug in the power! To change the wiring or move the board, you must remove the power before operating. Incorrect use, short circuit between solder joints, or short-circuit between parts can cause chip damage. 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 Maximum Power Per Channel: 100W Model Number: TPA3116P Type: Home Amplifier Feature: subwoofer amplifier colour:Blue Material:plastic Package Contents: 1 x TPA3116 Subwoofer Board with Knob(Knob color is random, you cannot choose the specified color) 1 x 3P Cable Only the above package content, other products are not included. Note: Light 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.
