How did Mussolini relay his declaration of war to the people during his speech on June 10,1940? I've posted the video below, and in it, there dont't seem to be any microphones near him, but his voice is amplified.

At 1:37 one can clearly see two small microphones on the ledge in front of him. The microphones stay still in front of his minor movements.
