Memory Consoles - Memory-based consoles have become very popular in almost all larger installations, particularly theatres. These new types of controls have completely replaced preset consoles as controllers of choice. Used . . Memory consoles are preferable in productions where scenes do not change from show to show, such as a theatre production, because scenes are designed and digitally recorded, so there is les.
