What is eARC Receiver? Do I Need it?

Enhanced Audio Return Channel (eARC) is a new technology implemented on AV receivers to improve audio output quality. It allows for high-quality sound signals to be transferred from your TV to your receiver, which then processes and amplifies them for an even better sound experience. If you want to enhance the overall quality of your home theater setup, eARC is worth considering.

In this article, our audio engineers will help you better understand this cable type so you can decide if you need a compatible eARC receiver.

HDMI eARC, Explained:

The introduction of HDMI eARC has taken the digital world by storm. As the preferred digital connector of television, HDMI has always been known as a reliable way to transmit high-quality audio and video. But with eARC, it takes things up a notch. The latest version of HDMI promises to deliver an immersive audio experience like never before.

HDMI eARC stands for Enhanced Audio Return Channel, offering significant improvements over its predecessor, ARC. With eARC, you can expect higher bandwidth and greater data transfer rates than traditional ARC connections. This means you can enjoy uncompressed surround sound formats such as Dolby Atmos or DTS: X without any quality or degradation in sound.


One of the most significant advantages of HDMI ARC is that it allows for high-quality audio transmission without any loss in fidelity. This means you can enjoy your favorite movies, TV shows, and games with crystal-clear sound quality that will transport you right into the action. Additionally, since HDMI ARC only requires one cable to transmit video and audio signals, it significantly reduces clutter around your entertainment system.

Furthermore, HDMI ARC is incredibly easy to set up. All you need to do is connect your TV’s HDMI port to your soundbar or AV receiver’s ARC-compatible port using an appropriate cable.

Connecting a TV to a Receiver with No eARC:

If your receiver has no HDMI eARC, keep hope because there are several ways to connect your device to the receiver without using HDMI. Below are the different approaches you may apply.

Method #1: Coaxial Digital Cables:

Connecting a TV to a receiver with no eARC can be challenging, especially if you want to enjoy high-quality audio. While HDMI cables are the go-to option for many people, they can be quite expensive. Luckily, another option offers similar results without breaking the bank – coaxial digital cables.

Coaxial Digital Cables:

Coaxial digital cables are much cheaper than HDMI cables, making them an ideal choice for anyone on a tight budget. Despite their affordable price tag, these cables can transmit high-quality audio faster and more reliably than other cables. This makes them perfect for connecting your TV to a receiver with no eARC.

Another benefit of using coaxial digital cables is that they are widely available in most electronics stores and online shops. This means you can easily find one that meets your needs and budget without spending hours searching or paying ridiculous prices.

Method #2: Optical Digital Cables:

Regarding audio quality, the type of cable you use can make a significant difference. While optical and coaxial digital cables can transmit high-quality audio, there are some notable differences between them. Optical digital cables are more expensive than their coaxial counterparts. However, their superior reliability when transmitting audio signals often justifies the higher cost.

An optical digital cable may be your best bet to connect your TV to a receiver without eARC support. These cables use light instead of electricity to transmit audio signals, which helps reduce interference and signal degradation. This means you’ll be able to enjoy higher-quality audio without any annoying pops or crackles that can occur with some cheaper coaxial cables.


The eARC receiver is an innovative, cost-effective, high-quality audio and video streaming solution. It offers a range of features such as enhanced audio and video formats, improved surround sound, and low latency streaming. It is also compatible with various devices, making it more convenient for consumers. This device has all the features necessary to ensure an excellent home entertainment experience.


What are the different types of eARC receivers?

The first type of eARC receiver is the entry-level model. These receivers provide the basic functions for high-quality sound and video transmission but may lack advanced features such as Dolby Atmos or DTS:X support. Entry-level models are perfect for those who want a simple setup without breaking the bank.
The second type of eARC receiver is the mid-range model.

Do AV receivers have eARC?
