  We present new near-infrared (IR) spectra (0.80-1.35um) of the pre-Main
Sequence source PV Cep taken during a monitoring program of eruptive variables
we are conducting since some years. Simultaneous photometric and spectroscopic
observations are systematically carried out during outburst and quiescence
periods. By correlating extinction-free parameters, such as HI recombination
lines and underlying continuum, it is possible to infer on the mechanism(s)
responsible for their origin. Accretion and mass loss processes have a dominant
role in determining the PV Cep irregular variability of both continuum and line
emission. The potentialities of the observational modality are also discussed.
