3 reviews for HDMI ARC Adapter, Tendak ARC Audio Extractor with Digital Optical TOSLINK SPDIF/Coaxial and Analog 3.5mm L/R Stereo Audio Converter for HDTV Soundbar Speaker Amplifier

    I got this because I am using powered monitors for TV audio in my bedroom. Normally you would use an audio interface on a desk to adjust the volume, but since I’m using it with a TV I need to be able to control the volume with a remote. I only want to use one remote with my TV, so either a fire stick or roku remote with volume control.This device comes into play because it plugs into the ARC port, which allows the TV to send a volume control signal to it. The adapter has RCA L/R as well as a headphone jack that can be controlled via the volume control on a TV remote over ARC. Note that SPDIF (optical) only carries a digital signal and is not controllable via TV volume output.Testing this device with an LG TV using a fire stick input on HDMI 1 and a short HDMI cable connected to HDMI 2 (ARC) connected to the audio extractor seems to work as expected. Adjusting the volume on the LG remote sends a signal to the audio extractor and changes the volume output on both the RCA and headphone jack. I’m using RCA to connect my powered monitors. Another use case can be to connect the RCA outputs to a small amplifier and use that to power a set of bookshelf speakers. Both setups allow for a full wall mounted setup with no receiver needed, perfect for a bedroom with limited space.My main problem with this device and the reason for 4 stars is that you cannot use a low quality USB power adapter. I tried all my phone chargers, usb chargers, and even power banks. Since there is an amplifier creating the RCA and headphone output, it uses the 5V input to power itself. The internal power supply is very poor at filtering, so you can actually hear the internal switching of low quality USB chargers. I ended up using the USB output of my TV to power it, but I would much rather be able to control it via 120V. So keep in mind that if you can plug in headphones and hear static or other noises with no HDMI connection, you will need a different source of power. And just because a charger is high quality doesn’t mean that it is a clean 5V for powering audio devices.

    Easy install. Works great. I was using my headphone jack from my stereo to my Ruko tv but for some reason it stopped working. The headphone jack in the tv was defective. So I purchased this adapter plugged it in and instant stereo! Now be aware that the HDMI cable is not included so that a extra expense. So when you purchase this unit make sure you purchase the HDMI cable also. Plus make sure your tv has a arc port. Now with that being said the headphone jack is the cheapest and easiest way to go. Just get a cord that plugs into your RCA jacks and the other end will plug into your tv headphone jack. You can do that for under 10 bucks. But this product works great but it’s going to cost around 35 bucks when all is done. I do recommend this product.

    This is an excellent choice to connect a smart tv with powered speakers and a powered subwoofer for a really nice sound system.
