J-Tech Digital ® ProAV ® Unlimited N x N HDMI Extender Over Ethernet Cat6 Extender Matrix 12X12 8X8 Switch Switcher Extender by Single Ethernet Cable up to 400ft (Transmitter)

I bought this transmitter and four receivers for a special project at our church this week. I spent last week installing network jacks behind all four TVs. That was the hard part, setting up the J-Tech equipment was easy, just followed their instructions and it worked.I plan on using this equipment in our sanctuary eventually, to replace similar hardware we are using today that we aren't overly happy with. For now, I have it setup to transmit an HD feed from a camcorder in the sanctuary to overflow rooms in the back of the church facility, the nursery, to actual overflow rooms and the pastor's office.We had a hiccup with one of the TVs not working, turned out it was a 720 resolution TV instead of 1080 and couldn't handle the 1080 feed. Once that TV was swapped for a 1080 resolution TV, it worked too.I have a micro-HDMI cable running from the camcorder to the transmitter in the sanctuary and then to a network jack from there back to our network closet, where I have one of the J-Tech switches setup. The same setup is in place for all the TVs, the only difference being that they are hooked to receivers. Connected my Surface Pro to each of the receivers and updated their IP addresses and MAC addresses, per the included instructions, made sure they were plugged into receiver ports on the switch and the transmitter was plugged into a transmit port and everything worked from that point onward.I watched one of our services from one of the TVs and everything was good, sound and picture, no issues.This is mentioned in the description of the product, but there is a slight delay between the source and the output, which is understandable. It is negligible, but these TVs are setup not far from the sanctuary and standing in the hallway outside the sanctuary, you can hear a subtle echo, sounds almost like a stadium effect. That's just because the volume was up on the TVs and the doors to the rooms were open. Definitely not an issue with the equipment, just something to plan for in scenarios where you are feeding TVs in close proximity to the source.I checked the J-Tech devices after they had been in use for a while and did not notice any heat issues or anything like that. No changes in quality or performance over extended periods of use. I've only just started using the equipment though, so I can't vouch for longevity just yet.I contacted J-Tech support a couple times to ask questions before buying and found them to be very helpful and knowledgeable about their products. There was a considerable delay between question and answer, but the questions were asked after-hours, night and weekends.

We installed 4TX and 6RX with a matrix switch. Video and Audio quality is really good. The configuration to have a single TX and several RX is very easy, however, it can be very tricky when you combine more than one TX and RX. Once, you have it configure correctly, it work excellent. Read the manual careful. I really recommend this product, it affordable and reliable.

I just got this product yesterday. The setup is very easy and straightforward. Now I can extend my different video sources (Computer, BD player) to different rooms. I tested this item with their network switch. The setting menu is different from common network switches and is customised for hdmi application. You can use your computer to control which signal goes to which place. The network switch has 24 ports which means you can connect it up to 12 inputs and 12 outputs. The video quality is good. And I haven't seen any delays with sound. Also I haven't encounder any HDCP issue which is a major problem for my previou hdmi extender.I will update my reviews in the future.

We use these in our church building to provide our pisignage slides to the TVs in our building and switch to our service video when service is going. Great picture and sound and easy install.

It works as described and it's an economical solution to connect HDMI sources to multiple HDMI displays with long cables. However I've not put the system in serious use yet since its going to be used in a new church building and the building is not ready for operation. I hope the system will work reliably without any issue, we will see. Other than that it's a good system and an affordable solution to what it does. The user manual really need to be improved though.

Only wish it could be powered by PoE.

A great product for distributing HDMI, easy to install and a good price for what you get.

So far so good . I'm very happy with the set, planning to buy more along with the switch. No loss in fidelity that I can detect though only over a 100' cable length.
