An essential element in any audio set-up, audio amplifiers are always an important investment. What is an audio amplifier? In simple terms, an audio amplifier is an electronic device that amplifies audio signals. When an amplifier receives low-power audio signals, it works to increase their strength or amplitude, to pass on a much stronger signal that can be used to drive speakers. This creates a sound that humans can hear, such as music or voice. Audio amplifiers are available in a range of forms, according to the task they are designed to perform. A headphone amplifier, for example, is a very small amplifier that passes on audio signals to headphones. Headphones are basically miniature speakers, so they require a miniature amplifier to amplify the audio signals they receive. That amplified signal produces the sound that is then played through the headphones for the wearer to listen to. Similarly, a power amplifier works in much the same manner, but in a much bigger way. Power amplifiers amplify the signals they receive to create an output that is strong enough to drive loudspeakers. Finding the right amplifier simply means choosing the right kind of amplifier for the job, whether that means choosing an old-school tube amplifier, an integrated amplifier or a pre-amp or processor.
