Professional Audio Introduction
Professional audio systems are composed of audio sources (music playback devices and microphone pick-up devices), control equipment (analog or digital mixing consoles), audio processors (previously using effects, equalizers, compressors, filters, signal distributers, delay devices, and now also digital systems that integrate these functions), power amplifiers (amplifiers), and loudspeakers. These devices are connected together using a variety of different types of cables and wires. Professional audio equipment requires high standards from users, who must have a deep understanding of the functions and uses of various equipment, possess professional theoretical knowledge, precise listening skills, strong tuning abilities, and emphasize the ability to diagnose and troubleshoot problems. The challenge lies in the design and tuning of the system.
