Live sound mixers, also known as mixing consoles, are used to control audio signals during live performances, enabling engineers to adjust levels, EQ, effects, and routing. Mixers come in both analog and digital formats, offering a range of features from basic mixing to advanced signal processing. Popular brands include Yamaha (MG series), Behringer (X32), Allen & Heath (SQ series), and Soundcraft (Notepad series). Live sound mixers are essential for concerts, events, and theater productions, allowing audio engineers to balance and modify sound in real-time, ensuring that every element of the performance is heard clearly.
