In the present analysis we study the transition from coherent to incoherent dynamics in a nonlinear triplet of broad band combs of waves*. We first reduce the original set of equations into a set where all submodes within a comb interact with all pairs of submodes in the remaining combs. We then develop a spectral formalism that in a self-contained way enables: (i) to determine the point of the transition; (ii) to obtain a convenient set of low dimensional equations modeling the full dynamics**. As shall be discussed in connection with accelerator physics, the results can be applied to a variety of parametric or nonlinear wave devices like beat wave accelerators, FELs, etc.
