What Is an AV Receiver? A Complete Guide

If you have ever looked behind your TV and just felt like giving up, you are not alone. Between the game consoles, streaming sticks, Blu-ray players, and speakers, it is incredibly easy to end up with a tangled nightmare of wires. You want everything to work together, but you do not want to crawl behind your entertainment center every time you switch from playing a game to watching a movie.

This is exactly why people buy an audio-video receiver. It serves as the main command center for your entire living room, organizing your gear so all your devices play nicely with each other.

Key Takeaways

• An audio-video receiver acts as a single plug-in for all your media gear, so you do not have a mess of wires running up to your TV.
• These devices decode surround sound formats to deliver immersive, movie-theater-style audio. 
• They contain built-in power boosters that deliver electrical power to your passive speakers so they can produce sound.
• You can swap between your Xbox, Apple TV, or cable box with one click of a remote.
• Getting a local AV technician to wire up and balance your setup saves you hours of frustration.

AV Receiver Explained

Let's break down what this black box actually does and why it is the heart of any good home theater setup.

At its basic level, an AV receiver is a device that controls and powers your home theater. The letters "AV" stand for audio and video. Think of it as three different tools in one chassis: a video switcher, a sound decoder, and an amplifier. 

Instead of plugging your gaming systems directly into your television, you plug them into the back of the receiver. The receiver then sends the picture to your TV and the sound to your speakers. It keeps things simple, clean, and organized.

Components of an AV Receiver

To get a better idea of how this unit does so many things at once, we need to take a look at the different parts inside.

• The Back Connections: This is the big grid of plugs on the rear of the box. It features HDMI ports for your modern gear, optical audio inputs, and screw-on terminals for your speaker wires.
• The Preamp Section: This part acts like a traffic cop. It handles the volume controls and lets you switch inputs, choosing which device displays its picture on your TV.
• The Audio Decoder: This is the digital brain that reads surround sound formats. It takes a single sound file from a movie and splits it into separate parts, sending voices to the center speaker and background explosions to your side speakers.
• The Built-in Amps: Speakers need electricity to make sound. The amplifier section takes the quiet audio signals and amplifies them to a level sufficient to drive your physical speakers.
• The Tuner: This is the classic radio part. It is why the device is called a "receiver" in the first place, allowing you to tune into local AM and FM radio stations.

How Do AV Receivers Work?

When you sit down and turn on a movie, a quick chain reaction happens inside the unit. Your streaming player sends a mixed audio-and-video signal over an HDMI cable directly to the receiver. The receiver immediately splits that signal in two.

It passes the video straight through to your television screen without messing with the quality. At the same exact time, the internal decoder reads the audio data. It decides which sounds go to which speakers in your room. Finally, the internal amplifiers boost those sounds and push them through the speaker wires so everything matches up perfectly with the action on screen.

Benefits of an AV Receiver

Here are the benefits of using an AV receiver to power your home entertainment system:

• Actual surround sound: Soundbars try to trick your brain by bouncing noise off your walls. A receiver runs physical speakers placed all around your room for true, immersive sound.
• Clean walls with fewer wires: You do not have to run five different HDMI cables up to a wall-mounted TV. You run one single hidden cable from your receiver to the screen.
• One remote control: You can turn on your systems, change inputs, and adjust the volume using a single controller.
• Use old and new gear together: Receivers act as a bridge. You can plug a vintage vinyl turntable and a modern PlayStation into the exact same system.
• Custom room tuning: Most modern units come with a setup microphone. The receiver plays test tones and automatically adjusts the speaker volume to match the shape of your room.

Conclusion

Buying a good audio/video receiver is the smartest shortcut to getting great sound and a clean setup. It takes care of the hard work of processing audio, switching video, and powering your speakers. But trying to figure out speaker channels, watts, and HDMI ports can get confusing fast.

Frequently Asked Questions

What is the difference between 5.1 and 7.1?

These numbers tell you how many speakers you can connect. A 5.1 system uses five normal speakers (front, center, and surrounds) and one subwoofer. A 7.1 system adds two rear surround speakers to create a more immersive sound field. 

Can I use a soundbar with an AV receiver?

Usually, no. Most soundbars include their own amplifiers and are designed to connect directly to a TV rather than an AV receiver. Receivers are built to power traditional speakers that do not plug into a wall outlet.

How long do receivers last before they get outdated?

The amplifier parts can easily last for fifteen or twenty years. However, the video hardware may become outdated after five to ten years as new display technologies and HDMI standards are introduced. 

What does eARC mean on the back of the box?

It stands for Enhanced Audio Return Channel. It lets your TV send high-quality audio back to your receiver over a single HDMI cable. This is perfect if you like to use the Netflix or YouTube apps built right into your smart TV.
