The Crestron® HD-MD-400-C-E delivers an incredibly simple and cost-effective multimedia presentation solution for classrooms and meeting spaces. It allows a laptop or mobile device (HDMI® or VGA) to be connected to one of three inputs at a table or podium, and routes the signal to a display or projector up to 230 feet (70 meters) away. An additional HDMI source can be connected at the display device location (or through an optional wall plate near the display). Fully automatic operation detects when a source is connected or disconnected at any input and turns the display on and off, alleviating the need for any control panels or remotes. Built-in scaling ensures an optimal video image for SD and HD video signals, as well as for high-res computer signals.
At US$54, this Crestron HD-MD-400-C-E is a genuine bargain, sitting well below the 25th percentile of US$71 and far under the median of US$134 from your 69 recent comparable listings. For a buyer, this price is an exceptional opportunity compared to the typical used market, where most units trade between US$71 and US$267.
This switcher is a well-regarded, reliable solution for small meeting rooms, offering fully automatic 3x1+1 HD switching, scaling to 1080p, and HDMI-over-CATx extender capability without needing a control system. Its standout upside is the included universal power pack and simple transmitter/receiver setup, making it a perfect, cost-effective choice for classrooms or huddle spaces needing a clean, plug-and-play multimedia presentation system.

Crestron was founded in 1972 in the United States by George Feldstein and built its reputation in professional AV, automation, and control systems rather than in traditional consumer hi-fi. It is a privately held company headquartered in Rockleigh, New Jersey, and its core business has long centered on integrated technology for commercial spaces and high-end residential systems.
In audio, Crestron is best known for installation-oriented products: control processors, AV distribution, streaming audio-over-IP systems, amplifiers, and architectural speakers. Its residential audio line is built around the Crestron Home platform and DM NAX distribution hardware, while its speakers are typically developed with partners such as Origin Acoustics rather than sold as standalone audiophile separates.
In the market, Crestron sits in the premium custom-install and high-end integration segment, not the conventional hi-fi retail space. Its appeal is strongest among system designers, integrators, and affluent homeowners who want whole-house audio, automation, and discreet in-wall or in-ceiling sound, rather than collectors looking for turntables, headphones, or vintage separates. It is a niche but major brand in residential and commercial integration, with audio positioned as part of a broader control ecosystem.
