The region of collective parametric instability for a set of coupled oscillators, subjected to periodic block pulses with random phases, is calculated analytically in the mean-field limit. An extremely rich phase diagram is obtained, with the instability appearing in a much wider region than that of the individual parametric resonance, and persisting in the overdamped limit.
