What does the DIR button do on the fader?

The DIR button on the fader is responsible for directing output to the Digital Input/Record (DIR) mode. When activated, it changes the path of the audio signal, allowing it to be routed specifically to the digital output. This is particularly useful when the user wants to send their audio signals directly to a digital interface or recording device, bypassing other internal routing options that may be set up within the system. This functionality is critical for achieving precise control over audio outputs and ensuring that the right signals are sent to the appropriate destinations in a production environment.

Other options, such as switching input types, accessing global settings, or controlling monitoring levels, represent different functionalities that are not related to the purpose of the DIR button. These functions are typically managed through additional controls or settings within the audio equipment and do not involve the specific behavior associated with directing output to the DIR setting.
