Definition of Amplifier

An amplifier is an electronic device that increases the amplitude of an audio signal, making it louder and more powerful. It takes the low-level audio signal from a source device and amplifies it to a level suitable for driving speakers or headphones. Amplifiers are commonly used in audio systems, musical performances, and recording studios.

Types of Amplifiers

There are several types of amplifiers, each with its own characteristics and use cases. Some common types of amplifiers include:

  1. Stereo Amplifiers: Stereo amplifiers are used in two-channel audio systems. They typically have two channels, allowing them to power two speakers. Stereo amplifiers are widely used for music playback.

  2. Multichannel Amplifiers: Multichannel amplifiers are designed to power multiple speakers in a surround sound setup. They can have multiple channels, ranging from 5.1 to 11.2, depending on the audio configuration.

  3. Integrated Amplifiers: Integrated amplifiers combine both the preamplifier and power amplifier in a single unit. They offer a compact and convenient solution for powering speakers.

  4. Tube Amplifiers: Tube amplifiers, also known as valve amplifiers, use vacuum tubes to amplify audio signals. They are known for their warm and rich sound characteristics, making them popular among audiophiles.

Features of an Amplifier

Amplifiers come with various features that enhance their functionality and performance. Some notable features of amplifiers include:

  1. Wattage and Power Output: Amplifiers are rated based on their power output in watts. Higher wattage amplifiers can deliver more power to drive speakers and produce louder sound.

  2. Impedance Matching: Amplifiers need to match the impedance of the speakers they are connected to. Many amplifiers have impedance-matching features to ensure optimal sound quality.

  3. Signal-to-Noise Ratio: The signal-to-noise ratio (SNR) is an important metric that measures the ratio of the desired audio signal to the background noise. Amplifiers with higher SNR provide cleaner and distortion-free sound.

  4. Input and Output Connections: Amplifiers come with various input and output connections, such as RCA, XLR, and speaker terminals, allowing you to connect multiple audio sources and speakers.

  5. Tone Controls: Some amplifiers offer tone control features, such as bass and treble adjustment, allowing you to fine-tune the sound according to your preferences.

Key Differences

While both AV receivers and amplifiers serve the purpose of enhancing audio quality, there are several key differences between the two. Let’s explore these differences in terms of functionality, connectivity options, audio processing, and multi-channel support.


The primary function of an AV receiver is to act as a central hub for audio and video components in a home theater system. It combines audio and video processing technologies, supports surround sound formats, and offers network connectivity for streaming services.

On the other hand, an amplifier’s primary function is to amplify the audio signal and power the speakers. Amplifiers do not have built-in video processing capabilities, surround sound decoding, or network connectivity.

Connectivity Options

AV receivers typically offer a wide range of connectivity options, including HDMI, optical, and coaxial inputs for audio and video sources. They also have multiple HDMI outputs for connecting to a TV or projector. Additionally, AV receivers have speaker terminals for connecting multiple speakers and subwoofers.

Amplifiers, on the other hand, have fewer connectivity options. They typically have RCA or XLR inputs for audio sources and speaker terminals for connecting the speakers.

Audio Processing

AV receivers are equipped with advanced audio processing technologies, such as audio decoding, room correction, and surround sound processing. They can decode high-resolution audio formats, create an immersive soundstage, and optimize the audio output based on the room acoustics.

Amplifiers, on the other hand, do not have built-in audio processing capabilities. They amplify the audio signal without any additional audio enhancement features.

Multi-Channel Support

AV receivers are designed to support multi-channel audio configurations, such as 5.1, 7.1, or even 11.2 channel setups. They have built-in amplification for each channel and can power multiple speakers simultaneously.

Amplifiers, on the other hand, can vary in terms of the number of channels they support. Stereo amplifiers typically have two channels, while multichannel amplifiers can have more channels for surround sound setups. However, amplifiers generally require external preamplifiers or AV receivers to process and decode multi-channel audio signals.
