48Gbps 8K HDMI over HDBaseT Extender Kit (150m/492ft)
KanexPro EXT-HD8K-150M extends 8K HDMI 2.1 signals up to 150m over CAT6. TX/RX kit with bi-directional IR, RS-232, analog audio de-embedding, 24V PoC, and…
Most HDMI extenders cap out at 4K and 70-100m - leaving integrators without a viable single-cable solution for long-run 8K deployments or large-venue 4K installations that push past the 100m barrier. The KanexPro EXT-HD8K-150M closes that gap by extending HDMI 2.1 signals up to 150 meters over a single CAT6 cable, delivering 8K@30Hz at 40m, 4K60 4:2:0 at 100m, and full 1080p at 150m - all without active optical cables or signal repeaters. The TX/RX kit ships with everything an integrator needs: bi-directional IR, RS-232, analog stereo audio de-embedding on both TX and RX, 24V PoC, and a 7-mode DIP-switch EDID manager. HDCP 2.3, HDR10, HDR10+, Dolby Vision, and HLG supported end-to-end.
- Extends HDMI 2.1 (48Gbps) signals up to 150m/492ft over a single CAT6 cable — 8K@30Hz at 40m, 4K60 4:2:0 at 100m, 1080p@60Hz at 150m
- HDMI 2.1 input on TX accepts 8K, 4K, and 1080p sources — HDMI 2.0 output on RX delivers to any compatible display
- HDCP 2.3 compliant with full HDR support — HDR10, HDR10+, Dolby Vision, and HLG pass-through end-to-end
- Bi-directional IR pass-through (20–60kHz) enables remote control of source and display from either end of the cable run
- RS-232 pass-through via 3-pin phoenix connector on both TX and RX for third-party control system integration
- Analog stereo audio de-embedding (L+R phoenix) on both TX and RX — local speaker feed without a separate audio extractor
- 24V Power over CAT6 (PoC) — power the RX from the TX over the same CAT6 cable, reducing power outlet requirements at the display end
- 7-mode DIP-switch EDID manager (1080p, 4K30, 4K60 × 2CH/7.1CH + sink copy) — no software required for setup
- Locking HDMI connector on TX prevents accidental disconnection in rack or behind-wall installations

Questions
- What is the maximum resolution and video bandwidth?
- The TX input is HDMI 2.1 at 48Gbps and the RX output is HDMI 2.0. HDCP 2.3/1.x is supported, with color space up to YCbCr 4:4:4/4:2:2/4:2:0 and 8/10/12-bit color depth.
- What are the maximum distances by resolution?
- 8K@30Hz reaches 40m/131ft, 4K60 4:4:4 reaches 60m/197ft, 4K60 4:2:0 reaches 100m/328ft, and 1080p@60Hz reaches 150m/492ft, all over CAT6.
- How is RS-232 wired between TX and RX?
- A 3-pin phoenix connector on both TX and RX passes RS-232 bidirectionally at 300-115200 baud for third-party control system integration.
- How is PoC used to power the receiver?
- Connect the 24V/2.7A supply to the TX DC 24V input; the TX powers the RX over the same CAT6 cable via 24V PoC, so no power outlet is required at the display end. The RX can likewise power the TX.
- What cable is required, and are patch cables acceptable?
- Use a high-quality solid-core CAT6 or CAT6a cable; CAT6 cable is not included. Avoid stranded patch cables for runs over 30m, and use CAT6a or CAT7 for runs over 100m.
- What are the unit dimensions and weight?
- TX and RX each measure 8.46 x 6.10 x 1.02 in (215 x 155 x 26mm) and weigh 1.46 lb (660g).
- There is no video at the display after connection. What should I check?
- Verify the CAT6 cable is straight-through (not crossover), confirm both TX and RX power LEDs are lit, try setting the EDID DIP switch to match the display resolution (for example position 5 for 4K60 2CH), and check that the source outputs a supported resolution.
- The image drops intermittently at long distances. What should I check?
- Ensure solid-core CAT6 cable is used, since stranded patch cables degrade signal quality significantly beyond 30m. Avoid running near high-voltage power lines, and use CAT6a or CAT7 for runs over 100m.
- What installs call for the EXT-HD8K-150M over shorter-reach extenders?
- It suits large conference rooms, auditoriums, broadcast studios, and digital signage where source equipment sits far from displays and 8K or 4K signal must reach up to 150m over CAT6.
- What distinguishes the HDMI input on the TX?
- The TX HDMI input uses a locking connector that prevents accidental disconnection in rack or behind-wall installations.
