4K HDBaseT 8x8 HDMI™ Extender Matrix (Loop) - 400ft (cat6)-UHD88-EXB400R-K

1. High-Performance 8x8 HDMI Matrix with HDBaseT Mirrored Outputs

The 8x8 18Gbps HDMI Matrix with HDBaseT Outputs is a high-performance AV distribution system that connects up to eight HDMI sources to eight mirrored HDMI and HDBaseT outputs simultaneously—supporting up to 16 displays at once. Fully compliant with HDMI 2.0b, HDCP 2.2, and legacy HDCP 1.x standards, it delivers uncompressed video at resolutions up to 4K@60Hz 4:4:4. With a full 18Gbps bandwidth, this matrix switch ensures seamless content transmission with support for Dolby Vision, HDR10+, HDR10, and HLG, delivering lifelike visuals and dynamic color across modern and legacy displays.

2. Optimized Signal Distribution and Long-Distance Extension

Ideal for mixed-resolution environments, this 4K HDMI matrix extender features independent 4K-to-1080p downscaling on each output, allowing you to connect both UHD and Full HD displays without compromise. Its HDBaseT outputs extend signals up to 150 meters (492 feet) at 1080p and 120 meters (394 feet) at 4K via a single CAT5e/6/7 cable, while Power over Cable (PoC) reduces the need for multiple power supplies. This streamlined setup is perfect for commercial applications like video walls, conference centers, classrooms, and large-scale digital signage networks.

3. Advanced Audio Capabilities and Device Compatibility

For complete audio flexibility, the matrix supports 7.1-channel audio pass-through formats including LPCM, Dolby TrueHD, and DTS-HD Master Audio, while offering audio de-embedding through analog RCA and coaxial outputs. The built-in IR matrix enables bi-directional IR routing, allowing remote control of source devices from display zones. Comprehensive EDID management and CEC pass-through further enhance device communication and integration, ensuring reliable signal negotiation across your entire AV setup.

4. Flexible Control Options and Professional-Grade Design

Control is flexible and user-friendly via front panel buttons with OLED display, IR remote, RS-232, LAN, or WebGUI. Designed with a 1U rack-mountable chassis, this HDMI matrix switch is built for 24/7 reliability in demanding environments. Whether you're managing a control room, outfitting a commercial AV installation, or upgrading a 4K matrix extender system, the UHD88-EXB230R-K offers scalable performance, robust feature support, and uncompromising signal quality.

FAQs

Yes, you can purchase these things directly from us. Please contact us & we will assist you further.

No, this product doesn not extend multiple screens. It will duplicate the input sources to multple outputs.

Yes, you will be able to get a signal beyond the mentioned distance but the quality of the video decreases with increase in the distance and that too when using with shielded CAT6 cable.

Yes, you can implement the daisy chain method.

Both the ends of the CAT cable should be termed as EIA-568B & the cable should be straight & not crossed.

We recommend you to use High-Quality HDMI cables & shielded CAT6 cables.

Yes, you can purchase the additional transmitter from us. Please contact us & we will let you know the price.

Yes, you can purchase the additional receiver from us. Please contact us & we will let you know the price.

No, this product doesn't upscale/downscale the video resolutions.

You can extend the display devices up to 400 Feet when using with a shielded CAT6 cable.

The issue might be with the CAT cable. This might be due to the external interference of the signals & CAT5e has low bandwidth as compared to the CAT6. We recommend you using shielded CAT6 cable.

If the power and link led lights does not illuminate on the RJ45 port of the transmitter and the receiver, then the transmitter & receiver might be dead.

Please contact us so that we can troubleshoot the issue.

You can upgrade the firmware by connecting the PC & this device via RS-232 cable.

Please note that this product only supports the CEC function between HDMI input & HDMI output 1.

No, optical output doesn't supports CEC due to its limitations. CEC will work only with HDMI devices.

HDBaseT is the technology used for long distance transmission of lossless signals, resulting extremely low latency & giving the best picture quality.

In normal extenders, if you extend your signals up to some extend, the quality of the signals will degrade & you may find some latency issues. HDBaseT is the lastest standard which provides extending your signals to the longer distance without degrading the quality of the signals & with 0 latency.

We recommend you using a shielded CAT6 cables for optimum performance.

Our all the extenders supports IR Frequency & the devices using RF frequency will not be compatible with our products.

The IR Blaster/Emitter should be connected to the IR out port on the Transmitter and the IR Receiver should be connected to the IR in on the Receiver.
