2x100W @ 4 Ohm TK2050 Class-D Audio Amplifier Board
This amplifier board is designed for the audio enthusiast who would rather build it than buy it. Each board has been thoroughly engineered, tested, and manufactured to above industry standards. Innovative features have been implemented into the board designs which have exceptional performance and would look as great in an art gallery as they will in your next audio project. The 2 x 100 watt amplifier board integrates Tripath's high performance TC2000 and TP2050 chips. Powered by any DC voltage from 10V to 32V, this high efficiency design is capable of driving 4 ohm or 8 ohm speakers with up to 100 watts per channel. Volume control is adjusted via on-board DIP switches. Thermal management is maintained through the use of an temperature activated fan.
