Master Fader is the main user interface for your DL Series mixer. Rather than knobs, faders and buttons on a large piece of hardware, you get powerful mixing tools on your tablet, Mac, or PC and at up to 20 different devices simultaneously. The intuitive design of the Master Fader app makes managing your mix, large or small, easy and efficient. Organize your channels with view and mute groups, utilize subgroups with full bus processing, control levels of channel groups simply with VCAs, and even lock out devices from specific capabilities within the app. And when you get a mix you like, you can save it all into a snapshot.
