We present phase-resolved spectroscopic observations of IX Vel (the brightest known novalike cataclysmic binary of UX UMa type) in the wavelength range 810-920 nm. We try to explain the relatively complicated shape of the observed emission lines in terms of the three component model of the emission from the system: disk, secondary star, "hot spot". The model reproduces the observations sufficiently well and confirms the presence of a narrow emission components in CaII triplet changing radial velocity in anti-phase relative to the orbital motion.
