Note buttons allow for announcement on/off cues. Click the bell to turn on the intermission chime. "ON" means that the bell will ring at intervals listed in the project. You can also click the black and white bell to ring it manually. The intermission is assumed to be 15 minutes long.
An barbell soundboard I made for my community theatre. I can plug my laptop or phone into a sound console and play sound effects without having to dig the sound files up. A barbell is a chime warning the front of house staff and audience that the next act will commence soon. This particular one rings when there are 5, 3, and 1.5 minutes left in the intermission. Additional rings may be necessary to draw the audience to the house.
