Digital mixer

In professional audio, a digital mixing console (DMC) is an electronic device used to combine, route, and change the dynamics, equalization and other properties of multiple audio input signals, using digital computers rather than analog circuitry. The digital audio samples, which is the internal representation of the analog inputs, are summed to what is known as a master channel to produce a combined output. A professional digital mixing console is a dedicated desk or control surface produced exclusively for the task, and is typically more robust in terms of user control, processing power and quality of audio effects. However, a computer with proper controller hardware can act as the device for the digital mixing console since it can mimic its interface, input and output.

Digital mixing consoles are typically used in recording studios, public address systems, sound reinforcement systems, broadcasting, television, and film post-production.

Most DMCs are expensive and sophisticated tools. The most common issue related to the DMC is the complex structure, which can be difficult to navigate without previous experience or knowledge of the system. The user usually requires a basic understanding of signal flow, audio terminology, and hardware implementation.

Part of the solution to alleviate operator issues is to automate whenever possible. The advent of modern digital computer technology has now made it possible to install sound system components that will almost operate themselves. When upgrading or installing new sound systems, it is advantageous to install items that require as little hands-on, human operation as possible.

A digital mixing console can offset the lack of operator experience because it can store the settings programmed by an expert mixer. For example: A knowledgeable person can adjust all of the microphone settings, monitors, etc. for a given event. After everything is properly adjusted, that set-up is assigned a name and stored in the memory. Afterwards, a less knowledgeable operator can simply select that setting on their console or computer.
