HDMI2.0/HDCP2.2 Compliant
This HDBaseT extender can transmit [email protected] 4:4:4 UHD video signal up to 40m/130ft or 1080P up to 70m/230ft over Cat5e/6/7 cable. With HDCP2.2 compliant and 18Gbps bandwidth, it can support HDR10.
Audio Return Channel
With the DIP switch of audio output on the receiver, you can configure the ARC mode to transfer audio from your TV (with ARC support) back to your AV amplifier connected to the transmitter. It can save you money, reduce your cable clutter and simplify your installation.
Audio Extraction
You can also switch to “S/PDIF In Mode” to configure auxiliary S/PDIF input, passing optical audio from the receiver to the transmitter. This 4K HDMI extender kit also provides an HDMI audio de-embedding with phoenix analog connector.
Bi-Directional PoC
Only one power adapter is needed to power both the transmitter and receiver. And bi-directional IR allows you to control both HDMI source and display at remote side, offering you more convenience.

Troubleshooting FAQ
1. What can I do if there is no video output?
- 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.
2. What can I do if HDMI ARC is not working?
- 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.
3. What can I do if ARC audio is intermittent?
- 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.
4. What can I do if the “Link” LED indicator is off or blinking?
- 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.
5. What can I do if there is no audio output from the optical S/PDIF port?
- 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.
6. What can I do if there is no audio output from the 3-pin audio port on the transmitter?
- 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.
7. What can I do if IR connection is not working?
- 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.
8. What can I do if RS232 connection is not working?
- 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.

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.
