A sound mixer is a device used to combine multiple audio signals into a single output. It is commonly used in live sound reinforcement, recording, and broadcasting applications. Sound mixers can range in complexity from simple two-channel models to large, multi-channel consoles with advanced features.
Sound mixers are essential for controlling the volume, panning, and equalization of multiple audio sources. They also provide a way to add effects such as reverb and delay. In live sound reinforcement applications, sound mixers are used to create a balanced and cohesive soundscape for the audience. In recording applications, sound mixers are used to capture and mix multiple tracks of audio for later editing and mixing. In broadcasting applications, sound mixers are used to control the audio levels of multiple sources for transmission over the airwaves.
