The Extron DXP HD 4K Series are high performance HDMI matrix switchers for video signals at resolutions up to 4K. They support HDMI specifications, including data rates to 10.2 Gbps, Deep Color up to 12‑bit, 3D, and HD lossless audio formats. DXP HD 4K Series matrix switchers incorporate Extron technologies such as SpeedSwitch^®, EDID Minder^®, and Key Minder^® as well as HDMI equalization and output regeneration to ensure reliable system operation. In addition, digital audio can be de‑embedded from any input and assigned to digital or analog stereo outputs for ease of integration. Available in fixed I/O sizes from 4x4 to 16x16, the DXP HD 4K Series is ideal for applications that require reliable, high performance switching of HDMI video and audio signals between multiple sources and displays.

The DXP HD 4K Series matrix switchers are designed for use with computers equipped with 4K graphics cards, media players and similar signal sources, as well as 4K native resolution displays. With a maximum data rate of 10.2 Gbps, the switchers support computer and video resolutions up to 4096x2160 @ 30 Hz with 8‑bit color in 4:4:4 color space. In addition, these matrix switchers fully support 1080p/60 with 12‑bit Deep Color. To maintain signal integrity, the matrix switchers feature automatic cable equalization on inputs and output reclocking to reshape and restore timing of the video signal at each HDMI output. These features combined with Extron Pro Series High Speed HDMI Cables allow longer 4K signal runs, reducing the need for additional signal conditioning equipment by compensating for weak source signals or signal loss on long cable runs. Additionally +5 VDC, 200 mA is available on the outputs for powering peripheral devices.

Flexible Audio Distribution

Audio routing in the DXP HD 4K Series is handled in two ways. Embedded digital audio from a source can be switched along with its corresponding video signal to any or all selected HDMI outputs. In addition, built‑in audio de‑embedders allow audio to be routed to discrete digital and analog audio outputs. The internal de‑embedders eliminate the need for external HDMI audio extraction products, reducing the number of boxes in the AV system and system complexity and maintenance costs. For applications requiring digital audio distribution, the de-embedded audio is made available on S/PDIF outputs in its native two‑channel or multi‑channel Dolby^® Digital or DTS format. For analog audio applications, the de-embedded signal is made available as line level stereo audio, on captive screw connectors. These audio outputs simplify integration with the local audio system.

Fast Reliable Switching

For enhanced integration of HDMI-equipped sources and displays, the DXP HD 4K Series features two Extron technologies: EDID Minder and Key Minder. EDID Minder automatically manages EDID communications, ensuring that all HDMI sources power up properly and reliably deliver content whether or not they are actively connected to the display devices through the matrix switcher. For HDMI signals with protected content, Key Minder authenticates and maintains continuous HDCP encryption between input and output devices to ensure quick and reliable switching in professional AV environments while enabling simultaneous distribution of a single source signal to one or more displays. If a signal from an HDCP‑compliant source is routed to a non-compliant display, the switcher outputs a full‑screen green signal, providing immediate visual confirmation that the protected content cannot be viewed on the selected display. With SpeedSwitch Technology, the DXP HD 4K matrix switchers deliver exceptional, virtually instantaneous switching speeds for HDCP‑encrypted content.

Easy Setup, Monitoring, and Control

The matrix switchers also provide advanced system monitoring and control via the RS‑232 and Ethernet ports. Global presets allow for simplified configuration changes and fast switching speed when using a separate control system to operate the matrix switcher. Front panel indicators provide visual feedback of routing, signal presence on all inputs and outputs, and the presence of HDCP‑encrypted content on each input.

With I/O sizes up to 16x16, the DXP HD 4K Series can provide AV signal switching for applications such as videowalls, command and control environments, emergency operations centers, and divisible meeting rooms, or for a centralized control room supporting adjacent classrooms. The DXP HD 4K matrix switchers are ideal for a wide variety of professional AV installations where distribution of high resolution, digital video signals is needed and a fully digital pathway is essential to maintain the highest possible image quality between multiple sources and displays.
