With the rapid development of display technologies, an increasing number of consumers are using an HDMI balun in their home theater, house of worship, workspace, and other locations. What is an HDMI balun? How does it help you deal with an HDMI signal? Is it worth purchasing? You can find all the answers in this blog.
What Is an HDMI Balun?
An HDMI balun (also known as an HDMI extender) is a device that allows you to extend HDMI signals over long distances using standard Ethernet cables.
This kind of device can help you transmit high-quality video and audio signals from a source device, such as a DVD player, to a display device, such as a television or projector.
How Does an HDMI Balun Work?
An HDMI balun typically consists of two components: a transmitter and a receiver. The transmitter is connected to the source device and the receiver is connected to the display device. The HDMI signal is converted into a digital Ethernet signal by the transmitter, and then transmitted over a standard Ethernet cable to the receiver, where it is converted back into an HDMI signal.
Advantages of HDMI Baluns
- Affordability: One of the main advantages of HDMI baluns is their affordability. They are generally less expensive than other types of HDMI extension solutions like HDMI over HDBaseT, HDMI over Fiber and HDMI over IP, which makes them an attractive option for budget-conscious consumers.
- Compatibility: HDMI baluns are compatible with standard Ethernet cables, which are widely available and relatively inexpensive. This makes them a convenient solution, as you do not need to purchase specialized cables to use them.
- Simplicity: HDMI baluns are easy to use and do not require any special technical knowledge or expertise. They are essentially plug-and-play devices that can be set up quickly and easily.
Disadvantages of HDMI Baluns
- Signal Degradation: One of the main drawbacks of HDMI baluns is that they are susceptible to signal degradation over longer distances. As the HDMI signal is transmitted over the Ethernet cable, it can become weaker and more prone to interference, which can result in degraded image quality.
- Limited Distance: HDMI baluns are generally limited to shorter distances compared to other types of HDMI extension solutions. While they can extend the HDMI signal up to 100 meters in some cases, they are more commonly used for distances up to 50 meters.
- No Support for Additional Signals: Some HDMI baluns only support the transmission of HDMI signals, and do not support other signals such as Ethernet, USB, and RS232.
Recommended HDMI Baluns
AV Access has two high-quality and cost-effective HDMI baluns for your home and business applications:
HDEX40-L is one of our best-selling 1080P HDMI extenders. It can extend full HD HDMI signal up to 50m/164ft via a single Cat 6a/7 cable. It is truly plug-n-play, no additional software or driver required. This slim HDMI balun also supports PoC and IR control, and built with a special EQ switch for 2 cable lengths (30m/50m).
If you prefer a 4K HDMI balun, 4KEX60-H2 is the right one for you. It is a 4K HDMI extender kit with HDCP 2.2 compatibility. It supports up to 4K@60Hz 4:4:4 8bit, and transmits UHD video, HD audio up to 35m/115ft over a Cat 6 or above cable. It also supports bi-directional PoC and one-way IR pass-through.
In summary, HDMI baluns are an affordable and convenient solution for extending HDMI signals over short to medium distances. They are easy to use and do not require any special technical knowledge or expertise.
However, they are susceptible to signal degradation over longer distances, and do not support additional signals. Therefore, if you need to extend HDMI signals over longer distances, or if you require support for additional signals, an HDMI balun may not be the best choice for your needs. In this case, you can turn to other HDMI extension solutions like HDMI over HDBaseT, HDMI over Fiber and HDMI over IP.
