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!

Work great for my folks

New TV and due to size needed to route equipment to another cabinet where the amp was. I've run Cat 5E/6 Ethernet cable before so I suggested this route to avoid any issues with RF signals and potential delays for sound. Have been working great. If you want to minimize your holes you can install with bulk cable and put ends on after routing cable. Otherwise use long enough Ethernet cable for your job and no need to mess with connectors. I used Outdoor rated Cat 6 cable as I use it for other jobs as well helping others. New Full Copper 1,000 ft Cat6 Ethernet Cable / Wire 1,000ft Cat-6 Waterproof Outdoor / Direct Burial / Underground ~ VIVO Platinum Tools 100054C Clamshell EZ-RJPRO HD Crimp Tool This tool is very easy to use and it is a few bucks more but works great with the ends listed next. Platinum Tools 100010C EZ-RJ45 Cat 6+ Connectors are super easy to use and I don't even test the cables any more as I haven't had any issues with these. Easy to see if you have each wire in the correct spot. If you would like to run wired jobs make the leap and buy this or similar equipment and you should have no problem at all.

Very unique PC gaming solution - 4k@60Hz (YUV 4:4:4) [4KEX70-H2]

Amazing HDMI extender with 4k@60Hz (YUV 4:4:4). The YUV is very important to maintain clarity at high resolution! This extender solved one of the biggest technical limitations I've ever encountered. I'm a PC gamer and until now I have been stuck in my office on the desktop PC. I wanted a solution where I could be in the living room with my wife while gaming on the computer. I didn't want to spend $2,000 on a gaming laptop that would be obsolete in 2-3 years and I didn't want to relocate my desktop PC as its needed in the office for my work. With this extender I was able to setup a mobile gaming station in the living room and still maintain high resolution 4k@60hz video. I ran a 100ft CAT7 Ethernet cable and an active USB extender cable down through the floor, across the basement ceiling and back up through the floor into the living room. I setup a small table with a 4k monitor, USB hub, mouse, keyboard, bluetooth speaker and this HDMI Extender [4KEX70-H2]. The results were amazing with a flawless video quality with no lag, pixelation or distortion. I can now chill on the couch in the living room while gaming on my desktop PC. Well worth it!

Solved 100% of my goal in regards to HDMI remote video connection

Received AV Access HDMI Extender model 4KEX70-L, plugged everything in, as instructed, and everything seem to work well for 1080P content. Only issue that I have is the IR function. I reviewed the instructions and connected what I believe to be the receiving IR (big sensor) to the IR input of the RX Extender and the transmitting IR (small sensor) to the IR output of the TX Extender. It seem to work for just a few minutes using the device remote, but then stopped transmitting the IR signal to the remote device. Removed power and recycle Extenders, but still not IR functionality. Then, tried to align the IR emitter, which did solve this minor problem. This was the only minor issue that I had to resolve. Upgraded the review from 4 to 5 stars, as this device does exactly what I needed to do. It works very well for the distance that I need to have HDMI/IR signal transmitted to and from. Great find! UPDATE (10/18/2016): I've had this device for a week and have put it through it's paces. This thing rocks, I used this device to setup a second zone connection in a living space with only a HDTV mounted to the wall exists. I have access to all of the components connected to the AVR, as if they are in the same room. As I'm using a AVR that can support multiple zones, I have the ability to use a single set of decent components, which in the past I've had to purchase multiple blu-ray players, media players and soon. With this device, I'm able to setup a second video zone where I only need to have power plugged in to the transmitter and at the receiver end I simply connect the IR emitter, Ethernet and HDMI cables to enjoy accessing all of my Media devices that are conveniently located in the basement within a server closet. This device is a great way to use a single Ethernet cable extend the HDMI connection for a device or component that is located several meters away. Within my home theater, I only have a HDTV, a blu-ray player and a 9.1 speaker system. Everything works, as if they are stacked up in front of the TV. UPDATE 3/20/2017: Unit began to flicker video after three (3) months of use and then gradually got worse. Reached out to AV Access support/sales several times over the passed 3 weeks about the difference between 4KEX70-L and the newly release 4KEX70-R and why DTS audio does not play. Apparently the "R" version is updated and supports more features than the "L" version. All my initial tests of the 4KEX70-L were with blu-rays using Dolby Audio 5.1, however, I have a large number of DTS audio blu-rays that never seem to play DTS audio. Not sure if it's a compatibility issue with this 4KEX70-L version and other devices, but DTS audio transport should be standard and there seems to be a problem passing thru DTS audio. Have reached out to AV Access again, concerning the issue and would like to request a exchange with the newer "R" version in order to support their documented "Stereo Audio,LPCM 2.1/ 5.1/ 7.1CH, DTS,Dolby pass through" claims and to address the flickering video issues. Of course when video drops out, so does audio. At this time reducing my review to 3 stars, pending AV Access response to my situations. UPDATE (06/26/2017): After working with AV Access Support, it was determined that the unit that I had been experience drop-out of video and audio was defective. Jessica from AV Access Support worked with me to ensure I received a functioning replacement unit which did resolve all the issues that I had been experiencing. The units that I have now are working exactly as advertised and I can not say enough about the support that I received from Jessica. She wanted to make sure that the product addressed my needs and stayed focused on my situation, to ensure I was satisfied with the operation of the units. THANKS Jessica for hanging in there with me. I appreciate the commitment that you have demonstrated to ensure your customers are satisfied.

Picture is perfect. Tested the HDMI from the satellite directly to ...

Was 5 stars, but just today went to use it and suddenly no sound is being transmitted. Picture is perfect. Tested the HDMI from the satellite directly to the tv in my game room and immediately had sound on that tv. So not sure what may have happened and of course my return window ended just 2 days ago. Only had the item for roughly 5.5weeks, give or take a few days. Basically useless if no sound will be passed. Quite disappointed as it was working as expected, last time I used it was roughly 2 weeks ago. As stated, was a 5 star item when it was working. Have only a run of 50' CAT6 cable between the receiver and transmitter so that shouldn't be the issue, especially since it was functioning. UPDATE (12Jul2017): So I found the issue, not at all related to the device. I had set my HDMI inputs on the TV to Ultra HD Deep Color after having everything working and hadn't used the satellite afterwards. I changed from the satellite to my PS3 and immediately had sound. At that point was puzzled as I had sound from the satellite to the game room TV, but not the master bedroom tv. Was driving me crazy, but tracked down the difference of not having Ultra HD Deep Color turned on the HDMI input in the game room. Changed that setting and sound was again passing from the satellite through this device and out of my bedroom tv. So as stated in my initial review, the device warranted 5 stars and that is exactly what I'm giving it.

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.

Perfect video and audio on new Samsung 65" 8 series TV

I ordered this unit because I had to extend an HDMI signal for about 90 feet. I installed new CAT 6 ethernet cable from my Dish network receiver to a remote TV. The unit worked perfectly for the video signal but the audio signal was absent. I corresponded with the vendor and tried various arrangements to see if i could get it to work. Ultimately, it would not pass the audio signal. I returned the unit to Amazon and re-ordered with a great discount code from the vendor for the replacement unit. The second unit performed perfectly for both video and audio. I think the customer service from the vendor was outstanding, with the exception of what appeared to be a bit of a language barrier. Ultimately, all is well, even though I have only had it in service for 1 week. The receiver unit operates at about 98 degrees in a 68 degree room, while the transmitter unit is about 10 degrees cooler. Some reviews have reported failure after several weeks of operation. I will wait to see if this unit proves to be durable over time. I recommend purchase for those that have to extend HDMI over long distances.

Long distance 4K/60 Hz HDR signal is no problem with the 4KEX70-H2

This review is for the AV Access 4KEX70-H2, HDMI 2.0 Over HDBaseT Extender. The packaging was excellent, with everything packed well to protect against any kind of shipping damage. The H2 comes with a transmitter, a receiver, a single 18VDC power supply, an IR transmitter, and IR receiver, two Phoenix male connectors for RS232 passthrough, and a user manual. Setup is very easy. Connect the transmitter and receiver with a suitable Ethernet cable, connect your HDMI source to the transmitter, connect your TV via HDMI to the receiver, connect the power supply to either the transmitter or receiver (Power over Ethernet is bi-directional so it doesn’t matter which unit has it), and then plug in the power supply. The units power up quickly, with both showing a steady power light almost immediately. There will be a slight delay as the transmitter and receiver negotiate the connection, but in all of my uses that is only a few seconds. Once the connection is stable the power and link LED lights will be on steady, the status LED will blink, and the HDCP LED will either be on or off depending on the signal having HDCP or not. I have an Onkyo TX-NR676 4K/60 Hz HDR receiver that has HDCP 2.2, a Shield TV, a PS4, and a Vizio M55-E0 4K/60 Hz HDR TV, and everything works exactly as it should. I use a 26ft CAT-7 cable run in-wall, with CAT-6 keystone passthrough jacks on each end, and CAT-7 patch cables that connect to each of the H2 units. I went with CAT-7 just to allow for future expansion, but I tested the setup with a standard 20ft CAT-5e cable and I had no issues at all, which supports the manufacturer recommendations for cable type and length. I’ve had no connection issues, no intermittent signal issues, and no signal quality issues. The receiver does get very warm to the touch, but since this is passively cooled and it uses the metal case to aid in cooling, I’m not concerned with it. As long as there is adequate ventilation I don’t expect any problems at all. I’ve had these powered up for over 8 hours and haven’t had a single issue due to the heat. I do have a UPS configured with my receiver as a master, so the H2 units are powered off when the receiver is turned off/goes into standby, so I don’t have any experience with heat when the devices aren’t being used – although I did read other reviews that stated the receiver is still warm even if there is no input signal being transmitted. Overall, I’m very happy with the 4KEX70-H2 in my home theater setup and I recommend using them if you have a long (25ft+) distance between your TV and your input devices.

Very nice

I examined all the manufacturers supplying HDMI over single cat6 before purchasing these. I purchased 3 of these based on functionality of the devices, the warranty, the reviews, and the ability of the transmitter to provide power to the receiver. I installed these on 1 run of 190ft cat6, 1 run of 130ft cat6, and 1 run of 115ft cat6. Cat6 600MHz copper cable (in-wall). All units worked flawlessly. 1080p, hdcp, audio perfect (I did not use the rs232 or IR capabilities). I usually do not write reviews, but was pleased by these devices. Very well packaged item and the build quality quality of these devices are excellent. The units were smaller than I expected too, making installation easy. These units will all run security feed video 24/7, so lets see how long they last. I will return with a follow up review if a unit fails prematurely. Updated 9-10-2018: These are still working great! 3 sets been running 24 hours a day, 7 days a week for the last 21 months with no issues at all.

Works well so far

This pair replaces an expensive Atlona 4K HDBaseT set that failed after <2 years. Hopefully these work for longer. The PQ (picture quality) for 1080P is equal to the Atlona boxes. No sparkles or sync problems. Note that before the HDBaseT Atlona boxes I had non-HDBaseT Atlona units that had trouble running 3D with good PQ - they were right on the edge of working, and they died prematurely, despite using a surge protector. HDBaseT fixes the PQ, so now I'm just looking for something reliable. I also prefer the power design: AV Access allows you to power both units by supplying power to just one unit/side (it sends power to the other side over the wire. As others have noted, the receiver unit does run hot. Here are thermal images after leaving them on for 8 hours with 80F degree ambient room temp. Hopefully this heat does not impact longevity, but if it does, I will update this review. I don't have a 4K projector to test 4K PQ, so others will have to comment on how well they perform on higher res.
