What is y splitter?

A Y splitter, also known as a Y-cable, is a cable adapter that splits a single input signal into two or more output signals. It is designed to be used with audio and video cables and can be used to connect multiple devices to a single output port. This type of splitter is commonly used in home entertainment systems, computer networks, and other audio and video applications. Some Y splitters are designed to split audio signals only, while others can split both audio and video signals. They come in various sizes and configurations, such as 3.5mm, RCA, HDMI, and VGA. It should be noted that using a Y splitter can sometimes result in a reduction in signal quality, especially if the signal is split multiple times.
