OREI 1x4 2.0 HDMI Splitter with Scaler Audio Extractor 4 Ports with Full Ultra HDCP 2.4K at 60Hz & 3D Supports EDID Control - UHDS-104A

I started implementing a setup that can swiftly shift between playing nintendo and singing karaoke one year ago (Winter 2023) - This splitter has been the core of my setup since then.The tricky part is in karaoke system, since it involves in a TV box for the music and multiple microphones. I ended up using a mixer to mix the music and mics. The mixer takes only analog input - and that's where this splitter shines: It extracts audio from either input and output it through a 3.5mm analog port, which works great for my solution.The switcher is also very convenient, because of it I can switch between nintendo and tv box for karaoke with just one button.

Works great. The EDID feature which allows downscale at each output is awesome. Even downscaled, the picture quality still great.

In my experience of splitting a 4K Firestick (to be kept at 4K setting) to a 4K projector (output: 1) and three 1080P monitors (output: 2,3,4), to get sound you have to use an additional audio extractor (4K rated) with output 1. EDID set to "copy" and 4K -> 1080: 2,3,4 set to "on". I do (use remote control power to) turn on the OREI & extractor FIRST, before the displays.

This product is nothing more than a computer moniter splitter. You can't use this to get an eARC audio connection to use this with a sound bar even with an optical cable at least from a Hisense TV that use seperate audio ports and with only one connection at a time.Thos product is is a total waste of money because it is outdated with HDMI 2.0 and 2.1 connection ports.Spend a few dollars more but bypass this if you need a real modern audio connection. This doesn't and you will have to waste your time on doing a return.I Orie support would just fess up with regards with calling this product crap they would just agree with you the customer on that this is a piece of crap out of date product that can't extract audio from anything.

Got this so I could play football on multiple TVs in different rooms, from a single cable box. Wanted to make sure sound and picture were synchronized. This worked perfectly and was exactly what I needed! I’m able to play 3 TVs on the single source with no delay and no impact to picture quality. (Has ability to go up to 4 TVs). Super easy setup. Highly recommend this.

Update:::Tried with AppleTV instead and it works flawlessly! Maybe something wrong with the Roku output, I’m not sure. Both video splitting and Audio works nicely!——————The Video splitter seems pretty good for 4k. But the audio extractor didn't work out for me..I got only some hissing noise. I have the audio extractor output going to an amplifier, and it just gave me a hissing noise. Its the same cable I used from a Roku XS2 device that works with the system I have. I'm not sure if there is something different I need to try.

I was using this to extract audio signals to RME ADI2 Pro. It failed to pass 24/192 but only 25/48. It also failed to pass SACD/DSD as it stated.

This Orei 1x2 2.0 HDMI Splitter with Scaler Audio Extractor is really a cool product. Works very well and is incredibly easy to install right out of the box--very little, simple, intuitive setup. Our new tv only has optical audio out which is not compatible with the 2nd room audio function in the receiver. I discovered that this is a very common problem. (Our old tv had both digital and analog audio outputs so this problem was never manifested.) This device converts the digital audio to analog which is compatible with the 2nd room audio function of the receiver.Also, the new tv is 4K, so I was somewhat worried that the picture quality might suffer due to the signal splitting within the device. Thankfully the device has no effect on the awesome picture quality.I am very satisfied with this device and highly recommend it. It also has great, reasonable pricing.
