AMX (formerly AMX, LLC) is an American manufacturer of video switching and control devices. It is currently owned by Samsung Electronics through Harman International Industries, and is part of the Harman Professional Division.
AMX designs and manufactures hardware and software for the distribution of video within meeting spaces, as well as across buildings or the globe using IP. They also create products that allow remote control of a wide variety of equipment including HVAC.
AMX home automation controls are now also available through separate applications ("apps") for smartphones and tablet PCs through its authorised product partners such as Touch Panel Control. The application is available for iOS, Android, and Windows 8 platforms.
In February, 2005, Duchossois Industries, Inc. acquired previously publicly traded AMX for US$315 million.
On November 1, 2006, AMX announced it had acquired Endeleo, a UK-based manufacturer of analog audio visual distribution technologies. Just over a month later on December 4, 2006, AMX announced the acquisition of another signal switching and routing company, Washington-based AutoPatch. Less than two weeks later, Matrix Audio Designs, a Canadian company based in Barrie, Ontario, was acquired by AMX that specializes in high-quality, multi-room distributed audio systems.
On October 2, 2007, AMX again announced the acquisition of another UK-based company, ProCon Technology, a company that specializes in configurable control keypad systems, switchers and distribution amplifiers. In less than a year, AMX had acquired five companies, bringing its combined employee head count to over six hundred.
On July 15, 2008, AMX acquired Atrium Group, an IPTV software company that eventually became AMX’s Vision2 IPTV solution.
On March 21, 2014, Harman International Industries, Incorporated announced it had signed an agreement with The Duchossois Group, Inc. and its affiliates to acquire AMX LLC for US$365 million.
A typical AMX system consists of the following elements:
- User Interface - The User Interface receives input from a user wanting to control the system. UI devices include touch panels, keypads, remotes, and mobile apps.
- Master - The "NetLinx Master" is a combination of the CPU, a Linux-based embedded operating system, and RAM and ROM memory. When an event is received via an interface device (such as a button press on a touch panel), the master executes NetLinx code written by a programmer. The Master then sends a message to the Controller, which responds appropriately.
- Controller - Commands are relayed to it via the master, and the Controller executes the commands to the required devices. Controller can be built into the same device as the master (such as an Enova DVX Series Presentation Video Switcher or a NetLinx NX Series Controller) or separate from it (such as on an ICSLan Control Box or a DXLink transmitter or receiver). Most current master also have control ports on it, but some (most notably the Enova DGX Series Digital Video Switchers) do not.
- Video Switcher - The video matrix switcher sends video from a selected source the appropriate display. AMX uses a variety of proprietary technologies (such as SmartScale for image resolution scaling and InstaGate Pro for HDCP key handing) to ensure fast, reliable switching of video while maintaining source video quality.
