Simple Explanation

A device that takes an audio or video signal, modifies it, and then outputs the adjusted signal at line level.

Concise Technical Definition

A processor is any device that receives a line-level input signal and adjusts it in some way to modify the signal before outputting it at line level. Processors can include devices like equalizers (EQ), digital signal processors (DSPs), and other devices that alter audio or video signals for various effects or enhancements.

Layman-Friendly Analogy

Think of it like a kitchen appliance that takes raw ingredients (the audio or video signal), processes them, and outputs a finished product (the modified signal). It could be a blender (like EQ or DSP) that changes the ingredients in a specific way, depending on the function.

Industry Usage Summary

Processors are widely used in both audio and video systems to modify and improve signal quality. In audio, processors like EQs and DSPs are used to shape the sound by adjusting frequencies, effects, and dynamics. Video processors can adjust aspects like color, contrast, and resolution. These devices are essential in both professional and consumer applications, from live sound reinforcement and studio production to home theater systems, as they provide the flexibility to modify signals to suit specific needs.

Engineering Shortcut

A device that modifies a signal in some way before outputting it at line level.

Full Technical Explanation

A processor is any device designed to take an audio or video signal, modify it through various means (such as filtering, equalization, or adding effects), and then output the processed signal at line level. In audio, processors are commonly used for adjusting frequency response (e.g., EQ), adding effects (e.g., reverb, delay), or managing dynamic range (e.g., compression). Digital signal processors (DSPs) are specialized processors that handle complex audio or video manipulations. Processors are crucial in professional audio and video production environments, home theater setups, and live sound applications, where they allow for precise control over signal characteristics and performance.
