When people think of an equaliser, they might imagine a small box on their audio system that adjusts the volume of all channels to the same level. However, equalisers can be much more powerful and versatile devices. They can be used to create a desired sound signature in your audio environment, help to correct any audio deficiencies, and boost the overall sound quality.

There are a variety of equalisers available, and each one offers its own unique benefits and features. Some common types of equalisers include mechanical, parametric, and psychoacoustic.
