The expression "crank up" means to increase or start something, usually in terms of volume or intensity. For example, you can crank up the volume on your stereo to listen to music louder, or crank up the heat in your home to make it warmer. It can also mean to make something more exciting or intense, like cranking up a party with lively music and dancing. It's an informal expression that can be used in various situations, but it's important to use it appropriately and not be too loud or intense in professional settings.
