Features and functions of AV receivers

Features of AV receivers can vary depending on the model and price range. Here are some of the common features that many AV receivers have:

• Audio decoding: AV receivers include an audio decoder that can translate digital audio signals into the original, discrete or multi-channel form. Receivers take various digital audio formats from media players and convert them for output to speakers. This enhances the surround sound system so viewers can experience real movie theater sound at home. Many AV receivers use Dolby digital and DTS technologies for multichannel audio decoding from DVDs, Blu-ray discs, and other digital cable formats.
• FM/AM tuner: An AV receiver can have a built-in FM and AM tuner that allows users to listen to radio stations. Tuners can have features such as RDS that display the station's name and information, as well as support for DAB for digital audio broadcasting.
• Network connectivity: Many AV receivers have network connectivity features that allow users to connect to the internet and access music streaming services. Receivers also support network protocols, which enable audio streaming from sources like NAS and PCs. HDMI Ethernet channel is network connectivity that supports a wired Ethernet connection.

How to choose an AV receiver

When choosing an AV receiver for wholesale purchase, it is important to consider functionality, design, build quality, and ease of use. It is also essential to choose receivers that support various audio and video formats, especially those popular with target customers.

Though the basic function of the AV receiver is to channel audio and video from different sources to speakers and a viewing screen, it has many more features that can hugely impact the entertainment experience. Modern receivers have five or more channels to amplify sound coming from a home theater system.

New technologies have impacted the choice of receivers today. Multi-room receivers with wireless streaming from a mobile device and downloading of streaming platforms like Netflix, Hulu, and Disney are now in demand. Such receivers can replace annoying cable systems and offer a seamless connection with music streaming services like Spotify without a physical connection. Receivers with HDMI ARC and eARC technology are preferred because of their easy connectivity with compatible TVs and less audio lag.

Receivers in the basic category tend to have fewer channels to amplify sound. They may only have Bluetooth wireless technology for connecting to mobile devices or music streaming systems. On the other hand, high-end models offer a wide range of connectivity options and more channels. Their audio and video processing chips are more advanced, providing excellent sound and image quality.

It is crucial to know the target customer's budget so that the right kind of receivers can be bought. Studying the potential market and customer preferences will help make informed decisions about features, make, model, and technology. Analyze the kind of speakers the buyer intends to use with the receiver and the room layout. Entering a simple room setup can be more complex, so it will be best to stick to a receiver with a basic configuration.

It is better to opt for receivers with on-screen menus and setup assistance to make setting up the system easier. If the target customer base needs assistance setting up the system, choosing a brand that offers support and guidance in the form of a dedicated setup team is a good option.
