Detail
First, let’s explore the function of an amplifier. An amplifier is a device used to receive input audio signals, then amplify and process this data to a much higher level than the original signal before transmitting it to the speakers for sound output. An amplifier does not produce sound directly but is crucial in enhancing the sound reproduction process. Without an amplifiers, your speakers would not function.
In simple terms, an amplifier is an important component in an audio electronic system that creates a stronger signal compared to the original input. It operates using electronic components such as transistors, tubes, or MOSFETs to boost the intensity of the input signal by a specified ratio.
In addition to basic amplification, an amplifiers also includes functions for signal adjustment, such as frequency control, sensitivity, distortion, and other signal factors. Some high-end amplifiers even have the capability to restore and correct weak or distorted signals. The connected speakers will receive power from the amplifier to operate effectively.
The construction of an amplifier is not overly complex and includes the following components:
- Power Transformer: The most crucial part of the amplifier; the larger the amplifier‘s power, the bigger the power transformer.
- Power Supply Capacitor: Acts as a reserve of electrical energy for the electronic circuits, helping to avoid excessive current spikes that can reduce the device’s lifespan during startup.
- Power Electronic Circuit: This component plays the most important role in the amplifier, increasing the received signal to a much higher intensity. It also determines the sound quality, distortion, noise, and transient response of the output sound.
There are many types of amplifier available on the market today. Firstly, based on the number of channels, we have 2-channel and 4-channel amplifiers. Based on functional configuration, there are preamplifiers, power amplifiers, monoblock amplifiers, and dual mono amplifiers. Classification by operational mode includes Class A, Class B, Class AB, Class C, and Class D amplifiers.
Each type of amplifier has its own advantages, disadvantages, and specific functions to better suit the particular needs of users.
