4K60 1×8 HDMI Distribution Amplifier over CAT6 — 150m/492ft
Extend One Source to Eight Receivers with HDR, HDCP 2.2, PoC & Balanced Audio Extraction
SP-1X8HD150MUPC 813982022980
Overview
Distributes one 4K60 4:4:4 HDMI source to eight displays over CAT6 at distances up to 120m (4K) or 150m (1080p) — eliminating the need for repeaters, fiber converters, or separate power supplies at each endpoint. The SP-1X8HD150M ships as a complete TX/8×RX kit with Power over Cable, bi-directional IR, RS-232 pass-through, and both coaxial and balanced analog audio de-embedding on the transmitter.
Built for large-scale commercial AV installations in campuses, convention centers, houses of worship, and hospitality venues, the 1U rack-mountable kit supports HDMI 2.0b with HDCP 2.2/1.x compliance, HDR/HDR10+/HLG/Dolby Vision pass-through, and up to 7.1-channel HD audio including Dolby TrueHD and DTS-HD Master Audio. A 27-preset EDID DIP switch plus full ASCII command control via RS-232 simplify integration with Crestron, Extron, and other control processors.

What is the maximum video resolution and bandwidth supported?
Up to 4K2K@60Hz 4:4:4 with 594MHz/18Gbps video bandwidth. The unit is HDMI 2.0b compliant and supports HDCP 2.2 and HDCP 1.x sources and displays.
What are the maximum extension distances?
Up to 120m/394ft at 4K2K@60Hz and up to 150m/492ft at 1080p@60Hz, each over a single CAT6/6a/7 cable run from the transmitter to a receiver.
How is EDID configured?
A 5-pin DIP switch on the transmitter rear panel selects a preset EDID profile covering 1080p and 4K2K resolutions across stereo, 5.1, 7.1, and HDR audio combinations, plus modes that copy EDID from the loop-out display or from a specific HDBaseT output.
How is the unit controlled over RS-232?
A 3-pin phoenix RS-232 port on the transmitter accepts ASCII commands at 115200 baud, 8 data bits, 1 stop bit, no parity, and passes through to each receiver's RS-232 port. Commands include s power z!, s reboot!, r type!, r status!, r link out y!, s hdbt y stream z!, s hdbt y hdcp z!, s edid in from
How many outputs does the SP-1X8HD150M have?
Eight. This is a 1x8 unit: one HDMI input, one HDMI loop-out on the transmitter, and eight HDBaseT/CAT outputs, each feeding a Premium Extender receiver.
What cable is required between the transmitter and each receiver?
A single CAT6/6a/7 cable per receiver. Use solid-core STP cable rather than stranded CCA patch cable to achieve the rated distances.
There is no video on one or more displays. What should I check?
Confirm CAT6/6a/7 STP cable (solid-core, not CCA) is used on the affected run, check the connection indicator LEDs on both the transmitter and the receiver, and if displays use mixed native resolutions, set the EDID DIP switch to the lowest common resolution across all connected displays.
There is no audio from the coaxial or balanced output. What should I check?
Confirm the source device is actually outputting audio over HDMI. For Dolby or DTS surround formats, set the EDID DIP switch to a preset that includes 5.1 or 7.1 audio, for example position 01111 for 4K2K@60Hz 4:4:4 with Dolby/DTS 5.1.
What kind of installations is the SP-1X8HD150M designed for?
It suits lecture halls, houses of worship, corporate campuses, and hospitality venues that need one HDMI source distributed to up to eight displays over long CAT6 runs, with local audio de-embedding for a house amplifier.
What value does the transmitter's loop-out and audio de-embedding add on a install?
The HDMI loop-out lets an installer feed a local confidence monitor at the source location, and the coaxial plus balanced audio de-embed outputs let the same signal feed a house amplifier or speakers, without adding a separate audio extractor to the rack.
