We present a microscopic description of dressed four-wave mixing (4WM) demonstrating spectral control of quantum correlations. Starting from a double $\mathrm{\Lambda }$ model for a single pump 4WM, we include a dressing field coupling the excited level, which leads to a six-wave mixing process. The model describes the enhancement of amplification and amplitude modulation in situ, due to the interaction of the dressing field, according to the experimental parameters. Moreover, the model predicts that the interaction with dressing fields allows the spectral control of the quantum correlations between pairs of sidebands by simply tuning the dressing field accordingly. This work paves the way towards all-optical control of quantum correlations in the continuous variable context.
