What are the benefits of using an AV receiver?

Besides enabling you to have optimal sound and system flexibility, AV receivers offer many other advantages to your home theater system and that include the following:

• Decodes the various ways a sound/soundtrack is entered into a medium such as DVD and translates it to the sound that you prefer to hear such as Digital Dolby or Atmos
• Helps overcome obstacles to high quality sound inherent in each room (as a result of the room size, the ceiling height, and type of flooring)
• Supports multiple inputs, giving users the greatest degree of flexibility when setting up their systems
• Amplifies sound and makes a home entertainment set up a reality
• AM/FM Radio - A home audio receiver has a radio tuner that allows users to listen to the radio stations they like. 
• Everything is integrated in a simple, easy-to-manage interface. By using the receiver's remote control, the user can easily control stereo equipment.

How to choose an AV receiver?

Here are a few things to consider when buying an AV receiver

• Channels: The number of channel determines how many speakers are included in an AV receiver. It is recommended to have at least 5 channels if you want to have a surround sound system
• Inputs/Connectivity: Consider the sources you'll be using, such as wireless music that will require Wi-Fi or Bluetooth input on your receiver. In general, the more connectivity your receiver has, the better.
• Video Switching: It is recommended to choose AV receivers that support 4K video switching so users can connect any video (DVD or Apple TV) and multiple 4K-capable devices to one display
• Power/Wattage: High-wattage receivers provide better sound quality even at low and medium volumes. Think about the size and design of the room where you will be installing your equipment, the bigger the room, the greater the power requirements
• Multi-room AV receivers: Consider multi-room receivers which can play two different audio/tv components simultaneously in different rooms. As a result, you can use your receivers for a variety of purposes.
• Features: For an immersive home entertainment experience, check for special audio/video features such as surround sound, multi-channel stereo, 3D streaming or multi-screen display.
