PART 3: ANNOUNCEMENTS & WARNING SOUNDS Warning Sounds only play through the onstage speakers for the Artists to hear. (They are also patched into my little calling desk speakers so I can confirm that they play when I hit those buttons.) Red Announcements play through the house speakers for the audience to hear. We have a variety of announcements pre-recorded depending on the situation. #stagemanager #stagemanagement #cirquedusoleil #michaeljacksonone #backstage #showcaller #theatre #behindthescenes
