Mixing consoles are used for many types of audio production besides studio recording, including television broadcasting, film post-production, live performances and sound reinforcement.
Mixing consoles can mix both analog and digital signals, depending on the mixer.
Some argue that analog mixing consoles are easier to use than digital; it is entirely a personal preference.
Sound quality is based on a myriad of factors. Knowledge of recording techniques beyond the mixing console is required to make professional-sounding recordings.
Many digital mixing consoles are fully digital, meaning all recording and mixing is done through a computer.
