The audio monitored on the OBS is different from the audio monitored on the Zoom H6

When monitoring the audio in real time in OBS I notice a strangeness, because it is not clean, it seems to be duplicated, or it seems to have an echo. This does not happen when I plug my microphone directly into the Zoom H6 equipment. I tested with only 1 microphone to make sure there is no echo from the environment.
