C500 Cat.5 HDMI Audio-Video Extender
What is an "Extender"?
An extender is a device used when your audio-video signals or cables need to be extended over a longer distance. Signal extenders help to transmit signals effectively over long distances, making them a better choice than passive extension cables. They are also referred to as "active extension cables", as they typically include built-in signal amplification chips to minimize signal attenuation caused by extended cable lengths.
Common types of signal extenders include:
.VGA Extenders / D-SUB Extenders
.HDMI Extenders
.USB Extenders / USB 2.0 Extenders / USB 3.0 Extenders
.KVM Extenders / Computer Extenders
