Mixer
A mixer may not be needed for all streamers, but can definitely be essential in specific circumstances. Mixers allow the two or more channels of sound to merge into one source, which can be very effective when it is necessary to filter multiple audio sources. For example, if you are having multiple guests for a group discussion, a mixer can allow all voices to be recorded with equal volume and clarity. This can be especially useful with the requirements of social distancing. A mixer can be a significant assistance in the right circumstances, and should always be considered, if not always used, by streamers.
