Great set up for long runs

We have a downstairs home theater with a remote receiver upstairs. It's ~200' of cabling from the computer downstairs near the TV up to the receiver and 200' back down to the TV. HDMI runs at that length are amplified/unidirectional and very expensive (~$600 last time we had a run replaced). Now that one of the HDMI cables started having issues instead of shelling out a bunch of cash to have someone fish around in our soffit and insulation I used these little boxes and some pre-existing CAT5e already pulled to both locations.

I'm only running 1080/60p but the signal has been rock solid. Setup was super easy - especially with PoE and only one power adapter required. IR relay is working fine as well. Very impressed by this little piece of kit.

Working fine.

Just installed today. Works fine right from the start over 100 ft. of Cat6.

Easy to Install, Easy to Use.

I purchased this set to replace a failing wireless HDMI transmitter I’ve used for years. Having been in the Commercial AV business for decades when I was younger and using Crestron and AMX HDBaseT systems, I was skeptical of such a simple inexpensive single wire system. With that in mind, I’m writing this review from the perspective of someone who has seen plenty of cheap HDMI extenders that were not HDCP capable/compliant wreaking havoc in distributed audio video systems. At this price, I thought why not give it a try.

The setup:

These devices were used to extend the (IP scaled) 4K UHD HDMI output of a Denon AVR-x2400 series AV receiver operating as an HDMI switch for 5 separate devices; Apple TV, DirecTV (Genie 75/500), Chromecast, WD HD Stream Plus, and a Samsung 3D Blu-Ray. These components are installed in my homes centralized distribution rack which sits ~15 linear feet downstairs from the Sharp Aquos Quattro display upstairs. This translates to ~40 feet of overall cable length due to the way it was run.

I was pleasantly surprised at how easy this was to install. Even the most novice of users will find there is not much need for the instructions. I did find the instructions useful to decipher the 4 front panel lights. The transmitter and power supply sit at the distribution point connected to a simple field terminated Cat5e cable (meaning I ran and terminated it myself which also means it’s not “certified” Cat5e). The output of the Denon AV receiver is connected to the transmitter using a cheap 3 foot HDMI cable.

NOTE: I mention the quality of these cables and terminations because many of the HDBaseT devices I’ve seen require some expensive or exotic deep color HDMI cables, a certified shielded Cat5 (or better) cable, and are intolerant to any line noise. I installed this in less than 15 minutes in the dark with the use of my Wife’s craft scissors, a couple of RJ45 connectors and a crimp tool that’s more rust these days than actual tool. If these devices work as well as they do for me given the redneck engineered 3 beer deep installation, even the most technically deficient (this would be most people’s mother) person can make this work EASILY. But I digress...

I’ve fed the IR output of the HDMI transmitter into an IR distribution block that is being used to repeat infrared signals to ALL the aforementioned devices in the rack, a second zone amplifier and a CD player. It works perfectly using a male 1/8th” stereo to make 1/8” stereo connector (I originally used a mono to mono cable which worked, but none of the other 3 IR receivers in my house would function). This was an absolute requirement due to the distributed system being downstairs in a closet. The wireless predecessor was intermittently sending IR signals and would drop out completely in some situations.

The receiver is mounted behind the TV in a manner that allows me to still monitor the front panel lights (just in case!). The IR receiver is attached to the front of the display and is nearly invisible to the untrained eye (its very unobtrusive compared to most - if utilitarian is your thing). The receiver is powered by the built-in Power Over Ethernet (PoE) supplied from the transmitter (downstairs). This is a HUGE benefit lending itself to the ease of overall installation. Although I didn’t try it, the single power supply can provide PoE to either the receiver or transmitter depending on which device is more available to be plugged into power. That means options and time saving.

The picture is flawless. There is zero jitter or noise in the distributed signal. Native 4K programming as well as the IP scaled 2160 30hz signals are no problem for these little inexpensive gems. I was pleasantly surprised to find that this system also supports the audio return channel (ARC) of the Sharp display. Likewise, the AnyNet and Aquos Link functions work perfectly (this is basically remote control over HDMI - Google it). Given the single cable design and inexpensive nature of this purchase, I was not expecting the return path functionality to work, but there it was. One less remote control to mess with. WIN!!

Overall, this system works perfectly and as advertised. I highly recommend them!
