An audio mixer is a crucial piece of equipment for recording studios and live performances, but it can be difficult to understand the difference between, for example, a mixer, an interface and a preamp. For starters, an interface acts as a bridge between an analog signal and a computer, and a preamp helps amplify the signal into the amplifier which allows a signal to be strong enough to be received by an amplifier and speakers.
But a mixer is capable of more functions, which is why mixers typically have a lot of knobs and sliders. This can make mixers seem intimidating, but they ultimately perform a fairly simple function. Mixers take multiple signals from guitars, microphones, or whatever other sources, and turn them into one or more outputs.
Feeding all of the signals from instruments and microphones into the mixer allows you to easily control things like the volume from the mixer. Many mixers go beyond simply providing balanced sound, though. You can often use a mixer for artistic flourishes, such as creating effects like reverb and delay. Small mixers with effects can be great for home music recording, as well as live performances.
Beyond singing or playing instruments, mixers are handy for other applications. If you’re a DJ — whether live or on the radio — you’ll need a mixer to seamlessly transition between different tracks. Mixers are even handy in non-music situations, such as using a PA or for podcasting. Read on for some of our favorite mixers.
