Logiciel Premiere pro n'ouvre pas l'option Egalisation parametrique simple

The settings for the Simple Parametric EQ effect can be found just above where your screenshot shows Mixage. This effect only lets you boost or cut a single frequency range, so its controls are limited (Center, Q, and Boost).

If you want a similar effect with a more visual display, I recommend the Parametric Equalizer or the Graphic Equalizer.
