Works at 4K and 60hz
Optical and Audio Out both output at the same time.
Cons:
Surround Sound does not work on a LOT of devices.
I bought this to get sound off an HDMI cable. My setup doesn't work with an audio output from the TV which is why a box like this would exist. It is to get sound off the HDMI cable before it enters the TV. The only device that worked with surround sound off of the optical cable that I tested was a PS4. When you go into the audio settings on the PS4 you can change the sound type to Dolby Digital and the optical output on the converter will actually output surround sound. On every other device I tested it only outputted stereo so only my front speakers were working. I have tested this on:
1) A high-end gaming PC with a 1080 TI graphics card. The 1080 TI can output audio off of the HDMI output. However the problem is that since this converter is an HDMI pass-through the sound output the computer sees is just the TV. It doesn't see the J-Tech device as an output which is probably the issue that every other device I tested also experienced. My computer saw my HDMI output to my LG TV as an output. Since the computer only sees the LG TV it knows the TV only has stereo speakers and so it forces my computer to only output with a stereo signal, so my rear speakers don't work.
2) Playstation 4 - This is the only device that worked because the PS4 has an audio setting where you can force the output audio type to Dolby Digital and it allows the optical output from the converter to send a true 5.1 surround sound signal through the J-Tech device.
2) Nintendo Switch - The audio settings on the Nintendo Switch lets you select Stereo or Surround Sound, but not specifically Dolby Digital or other types. So I could only get a stereo signal off of the converter.
3) Xbox One - Same issue as PC and Nintendo Switch. Can't output a 5.1 signal because it only sees the TV as a stereo setup.
4) Sony BluRay Player - Only outputs stereo
Again the main problem is that most devices don't see the J-Tech box as an audio output. It passes the signal through to the TV so the TV is seen as only a stereo output. Even though I have a 5.1 Logitech Surround Sound system plugged into the optical output on the J-Tech converter most devices only see the TV as a stereo device so it only sends a stereo signal. I even switched the J-Tech device to the 5-Channel position and it still does the same thing. Unless you have a PS4 or only need a stereo sound signal this device will not work for you.
This specific product was the most recommended since it supports 4k resolution and 60Hz frame rate. Just make sure you have at least 2 Ultra High Speed HDMI cables on hand.
1. One HDMI cable goes from your Xbox Series X and plugs into the Audio Extractor (HDMI IN).
2. The other HDMI cable goes from the Audio Extractor (HDMI OUT) into your TV/Monitor.
3. The Digital Optical Cable plugs into the Audio Extractor (OPTICAL OUT) and into your Astro MixAmp or charging station (OPTICAL IN).
4. Set the Audio Extractor to 5CH (your choices are TV, 2CH, and 5CH),
5. Go into "Xbox Volume and Audio Output" and select these settings:
Headset Format = STEREO UNCOMPRESSED
HDMI Audio = BITSTREAM OUT
Bitstream Format = DOLBY DIGITAL
Party Chat Output = HEADSET
And that's it! Now your Astro A40's or A50's will work exactly as they did with the older model Xbox. I hope this helps!
By the way, I am a pretty serious gamer and can promise you that this Audio Extractor has zero audio lag, sounds crystal clear, and keeps your video performance at 4k resolution with 60Hz frame rate.
Enjoy!
I hooked it all up, and voila, audio delay was GONE. However, I noticed my TV wasn't being recognized as HDR compatible. One step forward, one step back. Luckily they included a support card in the box, so I reached out to their support email. I received a reply within a hour on the day before Thanksgiving asking me to try the TV setting instead of 5.1 Soon as I did that, bam, HDR was up and running. Great response by their support team, and they helped save me a lot of money! Highly recommend this product for anyone in a similar situation.
I purchased this in order to extract the audio from an Apple TV that I was going to connect into the Blackmagic ATEM 1 Production Studio. Audio would then feed into sound mixer board. The system is configured for 1080p 59.94, and the the Apple TV is able to display the image just fine on the Blackmagic. When I introduce the JTech audio extractor in the HDMI path, things get really wonky. The display shows up but is flickering in and out constantly, so you can't get any solid connection. This happens for each audio option. Also tried plugging in a computer to the JTech and having that output and it is the same problem. I imagine this might work fine if connected to a TV, but it's not a solution for production environment. I'm not sure what the internals are doing such that it does not just pass through the HDMI signal, and so everything gets choppy once it hits the video switcher.
I've also tried the non-4K version of the JTech audio extractor and it is the same problem. Still on the search for an adapter that will do what I need to do and have a true pass-through so that the HDMI connection is not affected.
