Mixers
Mixers allow you to combine multiple sources of audio input into one stream. They also allow you to equalize and add some effects to the sound. Certain models also feature digital outputs that allow you to record and edit your audio feeds through software after or during a performance. Some mixers allow you to see all the channels as one stream on the computer, while others allow you to interact with each track separately. The latter set allow users to harness features that rival even the most expensive and complicated studio equipment.
