4×4 HDBaseT Matrix Switcher with 4K60 & CAT Extension (150m)
KanexPro MMX-4X4CAT-150M 4x4 HDBaseT matrix with 4K60 18Gbps, 492ft, 150m, PoC receivers, HDR, Web GUI.
The KanexPro MMX-4X4CAT-150M is an 18Gbps 4×4 HDMI matrix switcher with long-range HDBaseT extension up to 492ft (150m) per output, combining compact 1U form factor with enterprise-grade signal reach and built-in audio de-embedding for professional AV installations across large spaces. Four HDMI 2.0b sources are simultaneously distributed to up to eight displays — four via direct HDMI and four via HDBaseT to the included PoC-powered receivers — over a single CAT5e/6/7 cable per run. 24V Power over Cable eliminates local power requirements at each remote receiver. For 1080p signals, the maximum reach is 492ft (150m); 4K60 4:4:4 is supported to 394ft (120m). A key differentiator over the 70m model: the MMX-4X4CAT-150M includes coaxial audio de-embedding (3.5mm stereo mini-jack) and balanced analog audio outputs (5-pin Phoenix connector) on every HDBaseT port, enabling direct connection to amplifiers, DSPs, and audio zone controllers without additional hardware. Analog performance: PCM 2.0CH, Vmax 2Vrms, SNR >90dB, THD+N <0.1%, frequency response 20Hz–20kHz ±0.5dB. Full 18Gbps video bandwidth supports 4K2K@60Hz (YUV 4:4:4), all HDR formats (HDR10, HDR10+, Dolby Vision, HLG), and HD audio pass-through including LPCM 7.1, Dolby TrueHD, DTS-HD Master Audio, and DTS-X. Each output includes an independent 4K-to-1080p downscaler. An OLED front panel shows live routing and system status. Control via front panel, IR remote, RS-232, TCP/IP LAN, and Web GUI — integrates with Crestro

Questions
- What is the maximum CAT extension distance for 4K60?
- 4K60 4:4:4 is supported up to 394ft / 120m via CAT5e/6/7. For 1080p, the maximum extends to 492ft / 150m. The 70m variant (MMX-4X4CAT-70M) is available for shorter installations at lower cost.
- Does this unit include audio de-embedding?
- Yes. The MMX-4X4CAT-150M includes coaxial (3.5mm) and balanced analog (5-pin Phoenix) audio de-embedding on each of the 4 HDBaseT output ports. Coax supports PCM 2.0, Dolby Digital/Plus, DTS 5.1; analog outputs PCM 2.0CH stereo.
- Do the HDBaseT receivers need external power?
- No. 24V PoC (Power over CAT) is provided on all 4 HDBaseT ports. The included receivers are powered through the CAT cable — no separate power supply is needed at remote locations.
- What rack space does this unit require?
- The MMX-4X4CAT-150M is a 1U unit (44.5mm H, 440mm W, 200mm D). It fits standard 19-inch rack rails.
- How do I access the Web GUI?
- Connect the TCP/IP port to your network. The default IP is 192.168.1.100. Navigate to that address in a browser. Default credentials: Admin / admin. Update after initial setup.
- No video at a remote HDBaseT receiver — what should I check?
- Verify T568B wiring (no crossover), check PoC LED on receiver, confirm cable is under 120m for 4K60 or 150m for 1080p, re-seat RJ45 connectors, and check routing and EDID settings via Web GUI.
- What is in the box?
- 1x MMX-4X4CAT-150M matrix, 4x HDBaseT receivers, 1x IR remote, 1x IEC power cable, 1x RS-232 cable (1.5m), 4x 3-pin + 4x 5-pin Phoenix connectors, 5x IR blaster + 5x IR receiver cables, mounting ears, and user manual.
- Can I mix 4K and 1080p displays?
- Yes. Each output has an independent 4K→1080p downscaler. Enable it per port for 1080p displays while leaving other ports at native 4K — outputs are completely independent.
- What cable type is required?
- CAT5e, CAT6, or CAT7 with direct T568B wiring. Shielded cable (STP/FTP) is recommended for 4K distances. Avoid crossover cables and minimize patch panel hops.
