The three core performance attributes of any audio system are intelligibility (clarity of speech), loudness (sufficient sound pressure level), and stability (resistance to feedback). These parameters ensure a usable and effective sound reinforcement system.

“For speech reinforcement systems, performance must be measured by intelligibility, loudness, and system stability. Without all three, usability is compromised.”

The frequency identified by the numbers above each slider of a graphic equalizer is the center frequency. The center frequency is the specific frequency that each slider controls, allowing the user to boost or cut the amplitude of that frequency and those in its immediate vicinity. This helps in fine-tuning the audio signal to achieve the desired sound quality.

Incandescent lamps generate light by heating a filament inside a glass enclosure. This process is different from fluorescent, CFL, and LED lamps, which rely on gas discharge or semiconductor technology rather than a heated filament.
