What Is a Splitter? Understanding Its Function and Applications

May 7, 2025

Have you ever been in a classroom or training session, and the lecturer projects the same image onto everyone’s screen simultaneously? The technology that facilitates this is called a splitter, and they’re not just used in classrooms. 

Splitters are used to display video from a single source onto multiple screens at the same time. They’re frequently used in educational settings and large public gatherings, especially at corporate events involving large display screens, multi-room audio-visual (AV) setups, and breakout sessions.

Dive into splitter technology with us as we discuss how splitters work, common applications, and how you can use them to make your next corporate gathering or AV installation a success. 

What Is the Purpose of a Splitter?

A splitter is designed to transfer a single input signal to multiple outputs. In other words, you can use a splitter to display a single audio/video signal on multiple devices without significant quality degradation.

How Does a Splitter Work?

The way a splitter works may vary slightly depending on the type of splitter and the source of the signal, but the principle is the same across applications. 

Here’s a basic overview of how a splitter works:

  1. A source delivers an audio/video signal to the splitter.
  2. The splitter is connected to two or more devices via a cable.
  3. The splitter divides the signal into multiple identical signals.
  4. The splitter sends the duplicate signals to the connected devices.

Applications of AV Splitters

Splitters are used in a wide array of settings across different types of displays and device types, but some of the most common applications include the following.

Home Entertainment Setups

Splitters can be used to send a signal from a gaming console or streaming device to multiple TVs or projectors in home theaters and family rooms. 

Classrooms and Training Rooms

A splitter allows a teacher or instructor to display the same image, video, or digital whiteboard onto multiple screens or student monitors in a classroom or employee workshop.

Security Systems

Video splitters are used to distribute individual live feeds from security cameras to multiple recording systems or control rooms.

Digital Signage for Events

An output from a single media player can display the same advertisements, promotions, venue maps, or videos uniformly across all screens at corporate gatherings, trade shows, conventions, and other public events.

Airports

Splitters are an essential component of flight information display systems. They’re used to display a single visual signal to multiple displays, which ensures passengers can see real-time flight information, gate assignments, and delays wherever they are in the airport.

Corporate Conferences

A media player or laptop can send the same output to multiple projectors or screens at the same time using splitters, which enables keynote speakers and presenters to engage their audience more effectively and communicate their message more clearly.

Gaming Setups and Streaming

Gamers and other streamers often use HDMI signals to send the same video signal to a capture card and TV. 

Production and Broadcasting Studios

Splitters allow production crews to route audio and video signals to different recording systems, monitors, or live-streaming setups.

Types of Splitters

HDMI Splitter

Commonly found in home entertainment systems, HDMI (High-Definition Multimedia Interface) splitters essentially function as a port that connects to the source of the signal and can project high-resolution video and audio digitally onto several devices.

VGA Splitter

VGA (Video Graphics Array) splitters work much like HDMI splitters. However, VGA are analog rather than digital and can only transfer video signals. This type of splitter is considered to be a retro technology, and generally isn’t used in modern setups.

Audio Splitter

Ideal for PA systems and home theaters with surround-sound setups, audio splitters give you the ability to deliver audio signals to multiple speakers and distribute sound to different locations.

Fiber Optic Splitter

A fiber optic splitter is primarily used for large-scale or complex AV setups, such as professional broadcasts and corporate events. Fiber optic splitters allow for more customization than other types of splitters. They also typically offer greater bandwidth, allowing for signal distribution across long distances without notable quality degradation.

Coaxial Splitter

Coaxial splitters are generally used for cable and satellite TV signals. These splitters are best suited to low-bandwidth applications, as they tend to cause a small amount of signal degradation over long distances.

Active vs. Passive Splitters

Some splitters require power to maintain or amplify an input signal (active splitters), while others simply split the signal physically into multiple outputs without a dedicated power source (passive splitters).

Active splitters, sometimes called distribution amplifiers, are typically powered via USB cables or wall plugs, and they boost the signal to maintain quality across all outputs. They’re useful in event production and large-scale setups because they allow for longer cable runs and support high-bandwidth formats.

Passive splitters don’t require an external power source and are generally less expensive than active options, but they’re not appropriate for high-resolution signals. You’re likely to get some signal degradation, especially with more than two monitors or long cables. They’re great for simple uses like sending the same music to two sets of headphones, but they’re not powerful enough for professional AV setups or digital signage.
