The field and temperature dependence of the de Haas-van Alphen oscillations spectrum is studied for an ideal two-dimensional compensated metal. It is shown that the chemical potential oscillation, otherwise involved in the frequency combinations observed in the case of uncompensated orbits, is strongly damped and even suppressed in the case where the effective mass of the electron- and hole-type orbits are the same. This damping is even more pronounced in the case where magnetic breakdown occurs.
