PDF Press Release


London, January 31, 2018 – Amulet Hotkey Ltd., a leader in design, manufacturing and system integration for remote physical and virtual workstation solutions, announced new high-performance IP-based KVM Extenders. Built on the success of five generations and trusted in mission critical deployments, the DX KVM extenders feature enhanced multi-display image processing for demanding professionals and advanced workflows.

The DX KVM extenders are an excellent solution to provide secure remote access to workstations and systems in deployments such as command and control, design engineering, as well as media and entertainment. They can help increase 360-degree situational awareness, enable secure collaboration between teams, organizations and nations, or speed the design, visualization and simulation of anything from animation and movies to aircraft and cars. Amulet Hotkey’s DXR-H4 is a quad display rackmount KVM extender host card with an industry leading form factor to reduce rack space and data center footprint, where the DXT-H4 is a quad display desktop KVM extender host. Professionals can access demanding applications from anywhere using a broad range of devices for true mobility without compromising workstation power or performance.

“We developed the DXR-H4 and DXT-H4 cards in collaboration with leading movie production companies and global system integrators to meet diverse requirements from command and control operators to creative and design professionals while delivering the highest levels of security and flexibility,” said Andrew Jackson, president, Amulet Hotkey Inc. “Advanced and collaborative workflows can incorporate any system including high-resolution images, complex graphics and video to accelerate real-time analysis and decisions or boost creative team productivity.”

Breaking the KVM Distance Barrier
KVM extenders have been known to have distance limitations. To break the distance barrier while maintaining high-levels of performance, the DXR-H4 and DXT-H4 use Teradici PCoIP technology with advanced capabilities such as image decomposition, multiple codecs, dynamic network adaptation and built-in WAN optimization to manage bandwidth and image quality on LAN or WAN networks. Also, to deliver the best user experience for the available network resources, the DXR-H4 and DXT-H4 support features to reduce bandwidth requirements such as compressing and sending only the display pixels that are changing frame-to-frame, dynamic image quality adjustments, progressive image build-to-lossless, and intelligent data retransmission in the event of packet loss.

The DXR-H4 and DXT-H4 cards compliment Amulet Hotkey centralized workstation solutions such as CoreStation blade workstations, with integrated KVM extender mezzanine cards, and DX KVM extender host PCIe cards. They are an ideal solution to provide non-intrusive and secure remote access to systems that cannot fit a PCIe card or where the host system must remain physically isolated to meet security requirements. System isolation is maintained by using standard computer cables to connect the host computer to the DXR-H4 or DXT-H4, where network isolation is provided by the dedicated KVM extender network port.

“KVM technology has come a long way in the 25 years since Amulet Hotkey developed and patented Balun transformers for RGB video extension over Ethernet cables,” said Keith Grundon, technical director, Amulet Hotkey, Ltd. “Our new 6th generation KVM extenders enable true digital transformation for command and control centres providing secure data sharing within and across organizations and nations supporting a rapid and coordinated response to emergencies.”

“We deploy Amulet Hotkey KVM extenders to streamline our customer workflows, simplify studios and control rooms while creating flexible editing stations that can be functionally transformed with the click of a mouse,” said Phil Crawley, chief engineer, Jigsaw24. “With support for more displays, higher resolution, enhanced WAN performance and no hardware or software to install in the media systems, these new solutions help our film and TV customers securely integrate global teams and specialty partners into seamless workflows that boost collaboration and productivity to meet tight deadlines.”
