Name: 4K60 1×8 HDMI Distribution Amplifier over CAT6 — 150m/492ft
Brand: KanexPro
SKU: SP-1X8HD150M

Question 1

What is the maximum video resolution and bandwidth supported?

Accepted Answer

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.

Question 2

What are the maximum extension distances?

Accepted Answer

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.

Question 3

How is EDID configured?

Accepted Answer

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.

Question 4

How is the unit controlled over RS-232?

Accepted Answer

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

Question 5

How many outputs does the SP-1X8HD150M have?

Accepted Answer

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.

Question 6

What cable is required between the transmitter and each receiver?

Accepted Answer

A single CAT6/6a/7 cable per receiver. Use solid-core STP cable rather than stranded CCA patch cable to achieve the rated distances.

Question 7

There is no video on one or more displays. What should I check?

Accepted Answer

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.

Question 8

There is no audio from the coaxial or balanced output. What should I check?

Accepted Answer

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.

Question 9

What kind of installations is the SP-1X8HD150M designed for?

Accepted Answer

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.

Question 10

What value does the transmitter's loop-out and audio de-embedding add on a install?

Accepted Answer

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.
