We solve the Multichannel Kondo model with channel anisotropy using the Bethe Ansatz method. The model generates energy scales, characterizing the neighborhoods of the various infrared fixed points, in correspondence to the structure of the symmetry breaking in the channel sector. The nature of these fixed points also depends on the magnitude of the impurity spin $S$. We present a detailed discussion for the two channel case.
