8×8 HDBaseT Matrix Switcher with 4K60 & CAT Extension (70m)
KanexPro MMX-8X8CAT-70M 8x8 HDBaseT matrix with 4K60 18Gbps, 230ft, 70m, PoC receivers, HDR, Web GUI.
The KanexPro MMX-8X8CAT-70M is an 18Gbps 8×8 HDMI matrix switcher with simultaneous mirrored HDBaseT CAT outputs, designed for professional AV installations that require flexible, long-distance signal distribution from a single rack location. It connects eight HDMI 2.0b sources to up to sixteen displays at once — eight via direct HDMI and eight via CAT6 extension to the included PoC-powered HDBaseT receivers, reaching up to 230ft (70m) per run. A single CAT6 cable carries the full 4K60 4:4:4 signal and simultaneously powers the remote receiver via 12V Power over Cable, eliminating the need for a separate power supply at each remote display location. Every output supports resolutions up to 4K2K@60Hz (YUV 4:4:4) with 18Gbps uncompressed bandwidth, full HDR format pass-through (HDR10, HDR10+, Dolby Vision, HLG), and HD audio including LPCM 7.1, Dolby TrueHD, Dolby Digital Plus, DTS-HD Master Audio, and DTS-X. An independent 4K-to-1080p downscaler on each output allows mixed-resolution display environments without additional hardware. Advanced EDID management, CEC display control, and one-way IR matrix routing complete the signal chain. The matrix is controlled via front panel buttons, IR remote, RS-232 serial, TCP/IP LAN, or a browser-based Web GUI — compatible with Crestron, AMX, and other third-party control systems. Ideal for conference rooms, classrooms, control rooms, digital signage networks, and multi-zone AV distribution where sources must reach displays across a floor o

Questions
- What is the maximum transmission distance for 4K60 video?
- 4K60 4:4:4 is supported up to 230ft / 70m via a single CAT6 cable to the included HDBaseT receiver. For longer distances, consider the MMX-8X8CAT-150M which extends to 492ft / 150m.
- Can I route any input to any output independently?
- Yes. The matrix supports fully independent routing — any of the 8 HDMI inputs can be assigned to any or all of the 8 HDMI/CAT output pairs simultaneously, including the same source to multiple outputs.
- What cable type is required for CAT outputs?
- Use CAT6 or CAT6A shielded cable (STP). Standard CAT5e may work at shorter distances but is not recommended for full 70m performance. Do not use crossover cables — direct interconnect (T568B) wiring only.
- Do I need separate power supplies for the CAT receivers?
- No. The MMX-8X8CAT-70M provides 12V Power over CAT (PoC) on all 8 CAT outputs. The included receivers are powered directly through the CAT6 cable — no additional power adapter is required at the remote end.
- How do I access the Web GUI?
- Connect the TCP/IP RJ45 port to your network. The default IP address is 192.168.1.100. Open a browser and navigate to that address. The default login is Admin / admin. Change the password after initial setup.
- My display shows no video on a CAT-connected receiver. What should I check?
- Verify CAT6 cable wiring (T568B, no crossover), check that the PoC LED on the receiver is illuminated, confirm the cable does not exceed 70m, and re-seat the RJ45 connectors. Also verify the EDID setting matches the display resolution using the Web GUI.
- What is included in the box?
- 1x MMX-8X8CAT-70M matrix, 8x CAT receivers, 1x IR remote, 1x 12V/5A power supply, 1x RS-232 cable (1.5m), 8x IR blaster cables, 9x IR receiver cables, mounting ears, and user manual.
- Does the matrix support audio de-embedding?
- The MMX-8X8CAT-70M does not include coaxial or analog audio de-embedding outputs. For audio de-embedding, see the MMX-8X8CAT-150M which includes coaxial and balanced analog audio outputs per HDBaseT port.
- Can I mix 4K and 1080p displays on the same matrix?
- Yes. Each output has an independent 4K→1080p downscaler that can be enabled per output, allowing mixed-resolution displays to be connected simultaneously without affecting other outputs.
