Review: 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!
Review: 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.
