When searching for equipment capable of playing audio and visual media, there can be many options available such as DVD players, Blu-ray players, speakers, and other systems. While each of these devices are useful for specific media formats, trying to switch between each can be cumbersome and difficult if multiple equipment types are owned. With a device known as an AV receiver, multiple audio and video inputs can be connected to a single device so that their signals may be managed, processed, and routed to speakers and displays for enjoyment. As AV receivers can receive signals from devices such as DVD players and Blu-ray players, such electronics can operate as a central hub to control multiple sources with ease to make home theater setups simple. In this blog, we will discuss the AV receiver and its functionality, allowing you to better understand its benefits as a consumer electronic.
To best understand the usefulness of an AV receiver, it can be beneficial to first familiarize yourself with its main functionalities. As a central hub for both audio and video sources, many devices can connect to the AV receiver and may be switched between as needed without major setup changes. For audio sources, AC receivers are regularly compatible with CD players, turntables, and digital audio players. With the preamplifier section of a typical AV receiver, users may quickly select sources that they want to listen to, avoiding the need for constant wire management and change. In regard to video sources, common devices used with AV receivers include Blu-ray players, DVD players, video game consoles, laptops, and computers. Similar to audio sources, the AV receiver allows for quick switching and the ability to route video signals to various displays as needed to further control over multiple systems.
As AV receivers are specifically designed for home theater experiences, they are regularly capable of amplifying audio signals to operate multiple speakers and may decode surround-sound formats. Many receivers feature five or more channels of amplification, enabling them to drive surround sound setups while ensuring that signals are always routed to the correct speaker to benefit 5.1, 7.1, and even 9.1 channel configurations. With many forms of media now using surround-sound formats such as Dolby DTS, Atmos, and THX, the receiver also is capable of decoding various formats to ensure that surround sound technologies function as intended.
In order to connect with various devices for receiving audio and video signals, an AV receiver will often have a number of inputs. While many modern receivers have HDMI inputs for video signal transfer, many may feature component and composite video inputs for older devices. For visual media inputs, newer devices may rely on HDMI and digital optical inputs while older designs consist of coaxial and analogue stereo inputs. As AV receivers also relay signals to displays and speakers, they also often have multi-channel speaker outputs for 5.1 and 7.1 surround sound systems and various video outputs.
As technologies become more advanced and varied, AV receivers have been fitted with a number of diverse input types that go beyond the typical audio and video signals discussed before. As wireless streaming becomes increasingly popular, many receivers have taken advantage of Bluetooth and Wi-Fi technologies. With Bluetooth or Wi-Fi capability, receivers may wirelessly stream music or cast video for an ease of use. Some receivers may also feature USB ports and other varied inputs as well to accommodate computer accessories or electronics such as computer speakers, soundbars, and other devices.
As the brain of a home theater system, AV receivers can be very useful when one has multiple audio and visual devices that need to be managed with one system for ease. When shopping for such equipment, one should always find a model that has the inputs and features needed to be compatible with owned devices.
