What is Amplifier?
This is the circuitry that amplifies (increases) weak electrical signals so that they can be output through larger speakers. Most headphones do not have amplifiers and rely on the amplifier of the sound card to generate the sound. Larger speakers have their own amplifiers since the sound card doesn’t have adequate power.
