Introduction
The 1T- MV-8474 is a 4K Multiviewer designed for easy collaboration in huddle rooms, conference facilities,
medical, education, government applications or control rooms – anywhere that single or multiple inputs are
required, whatever the resolution, to be displayed on a single 4K screen. Control is quick and simple either using
the front panel, a remote control or a fully featured web interface.
The 1T- MV-8474 supports native 4K inputs (resolutions up to 3840x2160@30 on HDMI and 3840x2160@60 via
DisplayPort) together with up/down conversion, audio breakaway and selectable audio delay. Offering seven
multi-format video inputs (4x HDMI, 2x DisplayPort, 1x VGA/YPbPr) the system can display up to four video
windows simultaneously via sixteen different fixed layouts which can be simply recalled to present your content
in a variety of combinations. The sixteen layouts include Quad split, Picture-In-Picture, Triple, Side-By-Side, Full
screen and other, more complex, layouts with multiple layers. A single scaled HDMI output is capable of
supporting resolutions up to 3840x2160@30. In addition, seven independent stereo analog inputs and outputs,
allow you to switch audio separately from the HDMI stream and also integrate 7.1 audio with external equipment.
The on board web interface gives access from your PC to system setup, Full EDID management and audio control
including delay and volume adjustments , making it easy to integrate the 1T-MV-8474 into complex systems.
Control is via a Web interface, RS232, Ethernet, Infrared remote or from the front panel buttons.
The 1T-MV-8474 is an extremely flexible Multiviewer and a capable Presentation Switcher making it an excellent fit
for many different user applications.
