Description
TPA3118 2.1 Amplifier Module Digital Power Amplifier Board 12-26V 30W+30W+60W HIFI Speaker Subwoofer Amplifier Board
Product Description
This is a bass power amplifier board with preamplifier, bass frequency division processing and bass volume potentiometer control. It has a wide input voltage, high efficiency and high power. The board is already finished and tested and can be used directly after connected to speaker, audio input and power.
Features
* The amplifier board uses TPA3118 chip as core which is a high-performance digital power amplifier chip.
* Wide voltage power supply from 12V to 26V DC, energy saving , the efficiency is high.
* It can be powered by a good performance power adapter, laptop power supply, transformer power supply after rectifying filter, rechargeable source or car power supply.
* Power supply of 24VDC and more than 5A is suggest in order to avoid distortion or intermittent sound.
