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!

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.

This is my second 2 sets of HDMI Extender (HD Base-T) Signal 5 years ago I purchased a different set of HDMI Extenders and they didn't work at all. Keep in mind the Cat 6 cables were installed then, so connecting my new Extenders was easy and quick. We needed to buy 2 more TV's, one for my wife and one for me, but we thought they had to have Coax cable connections as I didn't think we could send from our two dish receivers HDMI signals which are about 75 feet away from our TV’s. I decided to attempt a different 2 sets of HDMI Extenders and these are the ones I bought. At Amazon they got excellent reviews so with prime as usual they came in 2 days. I only mention the 2 days as we live in the mountains of Colorado, and anything shipped that’s not prime takes as long as 8 to 10 days. Prime is a very big deal for us. The installation of these extenders was very simple and took only a few minutes. Even though I read the instruction’s I couldn’t understand why I needed only one power source for the Transmitter but none for the Receiver. My first set needed them on both ends. We’ve lived in our new home now for about 12 years and never were able to get High Definition! By the looks of these new extenders in the picture zoom they to me looked rather big and thick. I was wrong. Their about the size of my hand and less than ¾ inch thick. They even called them slim. There are only two very tiny led lights on the front. One for being plugged in and the other for synced. After connecting the receiver up, I went to the basement and plugged in the power supply and immediately both lights came on in the Transmitter. I thought surely this can’t be this easy, but when I went back upstairs, sure enough both light were on – in the Receiver, and yep it was ready to do its job. I turned on the TV and changed the source to HDMI and there was the best picture we’ve ever had here in the mountains. The bottom line of all this is now we don’t have to worry about finding TV’s with coax cable connections. That’s a very big relief as no TV’s today are being made with Coax connections. This all gets better yet. I called a major store that sells TV’s and told him I wanted TV’s with at least 1080 and 120 video smothers. He mentioned that they had last year’s smart 3D 4K Ultra HD TV on sale. The price was much better than I expected. I mentioned to this salesman that the dish receivers we have won’t give us 4k (Their hopper will and Dish is the first to transmit it) at least of the one’s I know? So why get the 4k Ultra HD TV then. This was a big surprise. Evidently the Samsung takes the signal and brings it up to almost the quality of dishes 4k output anyway. We’re going to see it tomorrow, if that really is true. We’ll probably come back to Amazon and buy it there.

I have installed a few of these with mostly good results. I did, however run into trouble this week when installing a pair to a setup that required 4k resolution. The extender passed 4k video from the Apple TV, but there were "sparkles" in the picture. We thought that maybe it might be a defective unit, so we replaced the extender kit with a spare one that we had on the van. Same issue. This was over a run of cat5 maybe 15' long. I replaced the HDMI cables on both ends to eliminate that as the possible culprit. Plugged the TV directly into the Apple TV with one of the HDMI cables, picture was perfect. I adjusted some of the video output settings on the ATV, but was never able to eliminate the issue. Will have to replace with a different brand extender, unfortunately. The extender worked great at 1080p, just not at 4k.

I run this unit at 1080 with a TiVO, PS4, and a computer over a 50ft Cat5e cable, and everything runs flawless, but I cannot feedback on 4K ability. I originally bought a different brand (Blackbird Pro) and returned it for this one, I made the right choice doing so, and I'll tell you why: 1) Heat. Both brand receivers generated heat, however this one is cooler while Blackbird got so hot I had concerns, as nothing I owned that didn't have active cooling ever got that hot. I believe the issue was with them using a 12V 1A adapter, as supplying additional power at the receiver side cooled it down. I can see the Blackbird burning out in less than 2 years, and no burn out on AV Access anytime soon. 2) IR: AV Access's 4KEX70-L came with a receiver and an emitter. Blackbird did not. I could not get any of my spares to work with Blackbird, nor did they sell a compatible set as a spare (AV Access does). I was told to shop for a pair on Amazon (two purchases & returns). 3) Cost. So far, the price of the Blackbird, plus a spare power adapter, plus 2 different sets of IR, and time waiting and experimenting trying to get IR to work on the Blackbird, I spent more than the AKEX70-L. I gave up, and sent it all back, and got the AKEX70-L. I have had no IR troubles save for the one I created for myself trying to chain it into an IR repeater kit. 4) Support: The manual is better, and (a shock to me) had IR Pinout drawings. With these I was able to make sure I could do more advanced IR tricks. I also emailed AV Access support regarding trying to link my AKEX70-L to an 3rd party IR Repeater kit. In the end nothing could be done as they used a proprietary receiver, but they were willing to help, and that means something. They didn't have to take time for connecting to a product that wasn't theirs, but they did. Not to many customer supports do that. The only thing I'm not fond of, and it is not enough to make me knock down a star, is having all the ports on one side. I prefer a sort of linear box design (power/cat5e IN on back/bottom, HDMI/IR/RS232 on front/top).

I had a simple dream. To have one gaming PC and to be able to stream it to my other TV's. I tried a few solutions, such as a Raspberry Pi. Streaming from the PC to the Pi worked pretty well with the Moonlight and Sunshine software, but didn't work for many movies due to copy protection. I tried a product from another brand, and that product streamed at the wrong resolution, causing black bands to appear. But this product actually works. I was very skeptical of the zero latency claim, but honestly I think it's a reasonable claim in this case - I cannot actually perceive any latency whatsoever despite being very very picky about things like this. So it may as well in effect be no lag whatsoever. It's better than streaming from the PC to the Raspberry Pi. Streaming to the Pi was low latency, but I could notice some jitter in the cursor. Here I can't notice any latency whatsoever, even when I look very closely for it. The image quality is very sharp, almost as good as with the PC directly attached via HDMI -- it is very crisp and looks great. Of course this solution does have some downsides, such as only streaming to one TV. And it requires a dedicated Ethernet cable (I used a flat 6a cable, and I think you probably want a 6a cable because it has MUCH higher bandwidth and is probably part of why its working so great for me). But it works very very well for what it was designed to do. I'm very impressed and I'm usually very picky. EXCELLENT PRODUCT!

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. Updated 12-12-2019: After 2 years, 11 months, AV Access replaced a dead receiver that ate a surge at no cost to me. The failure of the receiver was caused by the TV which surged and took out all of the electronics attached to it. Updated 7-23-2020: All still going strong 24x7 usage. Great devices. Bought 2 more. Updated 12-2021: An av company stole these from our customer when they replaced the display monitors. They otherwise ran great, no problems. Highly recommend.

After some research of HDMI extenders, I decided upon the AV Access model. Some of the features that brought me to this company were the POE capabilities and the surge protection. This was my first venture into mounting TVs to the wall with no wires showing! I ran some Cat6 and power to the wall, mounted the tv and installed the extender. I used a Sanus TV mount along with a Sanus Streaming Media Panel to mount the extender to the back of the tv. The tv was installed to the wall and I was able to leave the cable box in a room in the basement! The infrared signalling capabilities are great! This was my first venture into HDMI extenders and IR signalling and the result has been superb! The quality of the signal and audio is great. I've now mounted four tvs with these extenders. The longest run being is about 100 feet of cable and I am experiencing the same fantastic results. I am now using one of AV Access' splitters too! I did have a problem with one of the IR transmitter/receiver cords. I contacted customer service who was extremely helpful and responsive and got me out a new cord immediately. I was also happy to learn that I am able to use third party IR cords as long as they are compatible. I highly recommend this product and plan on installing the extenders on the last couple of tvs in the house.
