Video is nothing without audio, unless of course you are making a silent movie. An Audio Mixer is a device used to take in a variety of audio sources and allows you to create the “perfect mix” of audio signals and devices. Similar to those cool club DJs.
Also referred to as a sound mixer, mixing desk, or just “mixer”, this controller can take-in multiple audio sources and allows the user to adjust each source level; routes each signal to its particular output.
