What type of signal does a digital mixer convert?

A digital mixer is designed to handle audio signals and is specifically focused on converting analog signals into digital format. This process is crucial because digital mixers manipulate sound using digital technology, allowing for various audio effects, editing, and mixing to be performed with high precision and clarity.

When an analog audio signal, like that from a microphone or an instrument, is fed into the digital mixer, it must first be converted into a digital signal. This conversion allows the mixer to apply various digital processes such as equalization, compression, and multi-track recording, which enhance audio quality and provide more creative options during the mixing phase.

Other options describe processes or formats not directly related to the primary function of a digital mixer. For instance, converting video to audio doesn't pertain to the role of audio mixers, while digital to analog conversion is typically the function of a digital-to-analog converter (DAC), not a mixer. Lastly, concepts like stereo to mono relate to channel manipulation rather than the fundamental conversion process that characterizes how a digital mixer operates with audio signals.
