Back2Basics Series - Part 2 - Line Array, Subs and Amps

This is the second part of our Back2Basics series which is geared up for people with little of no experience outside of their chosen field and want to learn something new or for people just starting out in the industry;

Line array speakers - Are a type of sound reinforcement system that uses multiple small drivers (speakers) arranged in a line or curve configuration to produce a highly directional and controlled sound beam. They are commonly used in large-scale live events, concerts, and public address systems to deliver sound to a specific area with minimal sound dispersion or loss of energy. The line arrangement allows for more precise control of sound direction and coverage compared to traditional speaker systems, resulting in increased efficiency, lower distortion, and reduced sound interference between adjacent speakers.

Subs  - A subwoofer is a type of speaker that is designed to reproduce low-frequency sounds, such as bass and drums. It complements the main speakers by handling the low-frequency range, allowing them to focus on reproducing mid-range and high-frequency sounds. Subwoofers come in various sizes and designs, including powered and passive models, and can be added to existing audio systems to enhance the overall sound quality. Some subwoofers use a single large driver, while others use multiple smaller drivers to produce the desired low-frequency sounds.

Power Amplifier - is an electronic device that increases the amplitude (or "power") of an audio signal. It is used in sound reinforcement systems / music systems to drive loudspeakers. Power amplifiers take a low-power input signal from a preamplifier, mixer, or other audio source, and amplify it to a level that is suitable for driving a loudspeaker.

There are different types of power amplifiers, including Class A, Class B, Class AB, and Class D, each with its own operating characteristics and efficiency. Class AB amplifiers are widely used in sound reinforcement systems due to their high power output and low distortion. The specifications of a power amplifier typically include its output power, distortion level, and frequency response.
