What Is an Audio Amplifier, The Ultimate Guide to Sound Power & Clarity
An audio amplifier is an electronic device that boosts low-power audio signals (from devices like phones, mics, or instruments) to a level strong enough to drive speakers or headphones. It enhances sound clarity, volume, and quality, making it essential for home theaters, concerts, car audio, and recording studios. Key types include Class A, B, AB, and D amplifiers, each suited for different audio needs.
