Troubleshooting FAQ
- Check if the “Link” LED indicator is solid on. Also, check if the “HDCP” LED indicator is solid on or blinking.
- Make sure the source device and the display device are powered on. And make sure the source device is outputting video signal while the correct HDMI input channel is selected on the display device.
- Make sure all of your HDMI cables work normally. You can connect the source to the display device directly via one of these HDMI cables, to check if video can be shown normally on the display.
- Check if the “Link” LED indicator is in normal status (solid on).
- Check if the audio control button on the receiver is toggled to the “ARC” mode.
- Set your TV’s audio format to PCM or DD to check (DD+ or above is not supported).
- Make sure the HDMI ARC ports of the AV receiver and the TV are connected in setup.
- Make sure the ARC and CEC functions of the AV receiver and the TV are enabled.
- Use the remote controller to select the AV receiver as the TV’s audio output, and select “ARC channel” on the AV receiver.
- Make sure your HDMI cable work properly. You can connect the AV receiver to the TV directly via your HDMI cable to check if the ARC function works.
- Shielded Cat cable is recommended when using the HDMI ARC audio.
- Set your TV’s audio format to PCM.
- Add one more power adapter to the transmitter/receiver if available.
- Power on all the devices again to check if it helps.
- It is recommended to use a Cat5E/6/6A/7 cable, instead of Cat5 or flat cable.
- Please make sure the total length of your cable is less than 70m/230ft for 1080P, 40m/131ft for 4K resolution.
- Please make sure the connectors at both ends of the cable meet the IEEE T568B standard.
- Use a new cable, or try crimping your Cat cable connectors according to the IEEE T568B standard.
- If you need to use patch cables at both ends, the length should be as short as possible, no more than 5m/16ft. Please ensure all connectors meet the same standard (IEEE T568B). Also, please note that the total length of the patch cables and the Cat cable should not be over 70m/230ft.
- Please note that the S/PDIF audio can’t be de-embedded from the HDMI input or HDMI ARC. It only passes through the optical S/PDIF audio from the receiver side to the transmitter side.
- When using it, you need to toggle the audio control button on the receiver to the “S/PDIF In” mode.
- The 3-pin audio port can only output stereo audio which is de-embedded from HDMI input; it can’t de-embed audio from HDMI ARC.
- When using it, please make sure HDMI input audio format is PCM.
- Check if your IR connection method is correct. The IR receiver cable needs to be connected to the “IR In” port at one end, and the IR emitter cable needs to be connected to the “IR Out” port at the other end. Please note that the 3.5mm cable connectors need to be fully inserted into the IR ports.
- Check if you use the remote controller correctly and if you place the IR emitter head correctly. When you use the remote controller, it needs to be directly facing the IR receiver head. Besides, the IR emitter head should be placed closely to the IR receiving window of the controlled device.
- Try controlling the source device directly via your remote controller, without using the HDMI extender. Then check if the IR connection works.
- Check if the connection method of the RS232 cable between the HDMI extender and the control/controlled device is correct. It should be “TX-RX, RX-TX, GND-GND”.
- Perform an RS232 loopback test to see if the HDMI extender’s RS232 pass-through function can work normally.
- Try connecting the control device and the controlled device directly without using the HDMI extender. Then check if the RS232 connection works.
Other FAQ
An ARC HDMI extender supports ARC feature (audio return channel) and the audio from the receiver side can be sent back to the transmitter side.

Must have for Sonos Amp
Was told no one made a kit like this to transmit ARC to a Sonos Amp in the Av closet and they were wrong. This extender works flawlessly with no handshake issues and you get volume control also! Glad I found these after some digging online and would recommend this to anyone wanting to send ARC to an av closet without doing a long hdmi cable run. I have two of these units to run sound back from LG C1s to an av closet feeding Sonos Amps and they work perfectly as described.

Just what I needed for ARC I had a HDMI extender that didnt have ARC capability but got a new Samsung NQ90A 75″ TV and wanted to use the the ARC feature of the TV with my Denon 3400H AVR surround system. Setup is as follows: an HDMI 2.0 cable from the Denon AVR output port (It is the white one that is marked for ARC) to the AV Access HDMI 2.0 ARC Extender (Transmitter Unit) , then the Cat6 line (50′ length) to the back of the TV where I have the AV Access HDMI 2.0 ARC Extender (receiver unit) mounted, to another HDMI 2.0 Cable plugged into the HDMI arc port on the TV. The Transmitting unit was plugged into the outlet. The TV recognized the AVR automatically (make sure you have the HDMI settings for ARC in the Denon turned on first). The TV remote is able to turn the AVR on/off with the TV and easily raise and lower the volume in Dolby Surround with 4k picture. Great product!

Remarkable extender, ideal for moving all the audio equipment out of the way. Sadly, does not seem to support multi-challen audio over ARC. LG CX does not support DD+ or DTS either, but was able to consistently offer the 5.1 DD over eARC; the only way to get ARC was to use PCM (stereo). Optical seems to fill in that gap, but occasionally goes mute for about a second. Despite these shortcomings, this continues to be an amazing piece of hardware.

I needed a transmitter and receiver to send audio through Ethernet cables from my tv to my receiver room all the way upstairs. I tried another product but it didn’t support the audio ARC. This product works perfectly!

The HDMI Cat5 network extender that was installed in a house that I recently bought died. The old system worked fine as a one way with my old 46 in Samsung from 2007, but once the TV was updated to a TCL Roku 65 inches with smart TV. It was very frustrating to not get a return from the TV to the receiver. Fast forward 12 months and the extender died, so I did some research and I found and purchased a new one from AV Access with HDMI 2.0 ARC extender (model 4KEX70-ARC-H2) here on Amazon.
I was crossing my fingers as the sole reason to purchase this one was ARC and 4K return. I checked all the reviews and this one seemed to be the unit to purchase. My installation was typical and the distance between the transmitter and the receiver was well within the limits.
As I mentioned, my goal was to get it to work with a typical installation (BluRay sending signal to the TLC Rody TV and the TV sending the signal back to the AV Yamaha RX-V575). I did upgrade the HDMI cables to 2.0 for the return. All new cables and the receiver and transmitter so the installation was supposed to be a breeze. And for the most part it was a very straight forward. The extender to the TV worked great seeing in 4K Terminator 2, with phenomenal sound and video. No interruptions or flickering.
The challenge came with the ARC return back to the AV. Initially, it only worked for 3 seconds, and then stopped and the audio went completely silent. I checked the receiver following all the instructions and making sure the ARC was on. I unplugged the HDMI cable out of the TV, the TV speakers worked, and then, when I plug the HDMI cable the sound sounds in the AV speakers for a couple of seconds before it went silent again. I tried with Disney+, Hulu, Amazon video, Vudu, and all had the same issue. For some reason, the TV was trying to send a signal that was not being picked up by the receiver. I was able to control the TV audio sound from the receiver by turning ARC off (sound came out of the TV speakers but not 5.1 surround) and off (no sound coming out the 5.1 surround).
It turns out that my TCL Roku TV was set-up in Auto for the CEC-ARC return. It turns out that after an update, the only option that sends the return sound is PCM-Stereo. This is interesting because after making the adjustment to PCM-Stereo, I receive full sound 5.1 from my Roku smart TV when I stream back to the receiver using all the different smart apps (Amazon Prime Video, Disney +, Hulu, etc). I was concerned about the quality of the cat 5 cable, because mine is cat 5 and not cat5e or all the above.
You can get a cheaper extender if you do not want 4K or ARC, so I was really concerned about not getting all the features working (you can get a cheaper version for less features). However, like other posts mentioned the email support from this company is top notch. I sent them an email Sunday morning and I got a response Sunday evening by Ryan at ryan@avaccess.com or services@avaccess.com. Luckily, I had already solved the problem so I sent them an email back. They told me that the product has a 12 month guarantee and customer support so should not worry. So far, I am very happy with the sound that the TV is sending back to the receiver. I can fully utilize the 5.1 surround system that was built in the house and the quality is way superior to the TV speakers. I would definitely give a chance to the products by AV access. If it does not work with your current configuration the customer support will try to help you very quickly and if it does not work with your hardware, or it is faulty, you can always return it.

This is probably my second review ever, but the company asked if I would share my thoughts on the experience with the Extenders, and since they were so helpful, figured I would oblige. Being completely honest, I’m not super “techy� more joe average user, so take my review with a grain of salt (as they say).
I purchased the 2.0 Arc extender as I had about a 40FT run from my new Sony 4K TV to my AV receiver. I had read that HDMI gets a little “iffy�much past 25ft, so I ran CAT6 and planned on this extender system instead.
Setup and installation was pretty easy�really for most part it’s just plug and play. Currently I’m running Apps (YouTube TV, Prime…etc) on TV (internet via CAT6), which then transmits from the ARC output from the extender to my AV receiver which then gives me the surround sound. Admittedly, I have not invested in 4K devices like PS5 or 4K Blu-ray player to run it in reverse (from receiver to TV), though I have done this with regular 1080P Blu-ray and an old Xbox 360 which worked just fine.
Customer service is really good. Admittedly the first unit I received had some issues early on where the my picture was cutting in and out. I dealt with Ryan Xiebel where I could send an e-mail in the evening (I’m in the EST time zone) and would have a response in the AM. After a couple technical checks, Ryan coordinated an exchange of the unit. I was a little leery about the process only because I was sending the unit back at my expense (to a US location), though in the end they credited back the amt to my order, and sent out the brand new unit. If I had to make a suggestion to AV Access it would be to coordinate shipping labels so the customer doesn’t need to take the leap of faith in the credit process. It all worked out though�and I’ve been using the extender for about 5 months with no issues (now that I say that, I hope I don’t jinx myself!). Thx.

Works perfectly for ARC. I plugged it in, units synced up, and everything works great. I now can use my Samsung TV remote to control the TV, apps, and other peripherals. The Yamaha receiver is in a separate closet, and the TV now turns the receiver on/off, controls volume, and makes the room shake nicely. All with just the one Samsung remote and no clever programming needed.
