WHAT IS PASSIVE CROSSOVER ?

A passive crossover is an electrical circuit that divides an audio signal into separate frequency bands before sending it to individual drivers (such as woofers, tweeters, and mid-range speakers) in a multi-way loudspeaker system. The passive crossover consists of capacitors, inductors, and resistors that are combined in specific ways to create filters that attenuate (reduce)…

HOW A MICROPHONE WORKS ?

A microphone is a device that converts sound waves into an electrical signal that can be processed, amplified, and recorded. Microphones work based on the principle of transduction, which means the conversion of one form of energy into another. In the case of a microphone, the sound waves create mechanical vibrations that are converted into…

WHAT IS EQUALIZER ?

An equalizer (EQ) is an audio processing tool used to adjust the frequency response of an audio signal. It allows you to selectively boost or cut specific frequency ranges in the audio spectrum, typically ranging from low bass frequencies (20 Hz) to high treble frequencies (20 kHz). An EQ is commonly used in music production,…

WHAT IS ACTIVE CROSSOVER ?

An active crossover is an electronic device that divides an audio signal into two or more frequency bands, and then routes each band to a separate power amplifier that drives a specific speaker driver or set of drivers in a loudspeaker system. Unlike a passive crossover, which uses passive components like resistors, capacitors, and inductors…

WHAT IS POWER AMPLIFIER ?

A power amplifier is an electronic device that increases the amplitude or power of an electrical signal, typically an audio signal, to drive loudspeakers or other output devices. In audio systems, a power amplifier is usually the final stage of amplification before the signal is sent to the speakers. It takes the low-level signal from…

WHAT IS DJ MIXER ?

A DJ mixer is a type of audio mixing console used by DJs to blend and manipulate multiple audio sources, such as music tracks or sound effects, in real-time during a live performance or recording session. A typical DJ mixer has several input channels that can accommodate various sources of audio, such as CD players,…

WHAT IS DSP (DIGITAL SIGNAL PROCESSOR) ?

A digital signal processor (DSP) is a specialized microprocessor designed for high-speed processing of digital signals, such as audio, video, and other data streams. Unlike a general-purpose microprocessor, a DSP is optimized for performing mathematical operations, such as filtering, Fourier analysis, and other signal processing tasks, in real-time. DSPs are used in a wide range…
