2 X 100 Watt 4 Ohm Class D Audio Amplifier Board - STA508 100W Stereo T-Amp
Description：
- We have recently listed some combo kits which combines amplifier boards with power supplies we suggested. It will be easy to build your system and the combo kits are also high cost-efficient options compared to separated products.
- Please visit our store. You can find them in audio amplifier combo category. Another way to find them is to search on eBay directly with keyword: "amplifier combo kit".
Brief Introduction:
- This amplifier board integrates Tripath’s high performance TC2000 and STA508 chips supporting dual channel audio amplification. Powered by any DC voltage from 10V to 32V, this high efficiency amplifier board is capable of outputting up to 100W per channel. Besides, this board can be used to drive 4Ω or 8Ω passive speakers.
