What is an audio mixer?
Pro audio mixing consoles are electronic mixing devices that blend and control signal routing and change the levels (lower or boost). They can also control or add timbre (tone or EQ), dynamics and a wide array of special effects to all or individual audio signals (channels) and mixes.
A mixer can mix analog or digital signals, depending on the type of mixer. These individual processed signals are mixed to produce the combined mono, stereo output signals for recording or a sound reinforcement system such as a public address system or live band system.
