Brief Introduction:

Based on two TC2000 and four TP2050 chips from Tripath, this class-D audio amplifier board allows the creation of really good sounding multi-channel systems. Being compatible with power supplies ranging from 10V-30V, it can be used in many audio systems. This amplifier has four channels, all with the same power up to 100W each and sound quality, so the sound quality is simply outstanding. You can use any number of channels you like, and leave the others unused.

This is an exceptionally well designed amplifier, with a lot of power reserve, high fidelity, low distortion, good S/N ratio, high sensitivity, low consumption and full protection. Having all these almost ideal characteristics this amplifier is likely to become the basic building block of your future high fidelity system, or it can also become the element that will upgrade your existing system.
