Digital amplifiers are electronic devices that increase the power of audio signals using digital processing techniques. Unlike traditional analog amplifiers, which use continuous signals, digital amplifiers convert audio into a series of binary numbers. This allows for greater efficiency, producing less heat and consuming less power while delivering high-quality sound. These amplifiers are commonly found in various audio equipment, such as home theater systems, car audio systems, and portable speakers. Their compact size and lightweight design make them ideal for modern devices, providing powerful sound without the bulk of older amplification technologies.
