NoDoes anyone think you could use this to convert DSD that's output on HDMI out to COAX?
I also think the part is too expensive, but what alternative is there on the market? I have the part in use on my 4 channel digital crossover on the RPI3B+ and it runs well.If the measurements of the 2-channel version are anything to go by, this thing should not be worth its money.
Sure, however jitter can be introduced and HDMI is often not great on jitter to start with either;hence it’s bit perfect
Blumlein 88 said:I had a similar device. I did confirm the Toslink output was bit perfect. Had HDMI output on a laptop I fed into it, and a separate device record the Toslink. It worked as it should. However, the extractor had huge amounts of jitter way worse than even the HDMI. If you feed the device into something via Toslink it can filter some of the jitter out of course, but the amount was large enough it wasn't a good result.
Now that doesn't mean they are all that way. The one I had was a different brand from 3 years ago. You can always get it from Amazon and return it with in 30 days if you aren't happy with it.
I was puzzled byThis is a review and detailed measurements of the Amazon Basics 4K HDMI extractor. Member kindly purchased and drop shipped it to me. It normally costs $22.89 but was on sale for just $5!!!

The case is the standard metal one for these kinds of adapters. Power is provided with a supplied USB-A to barrel (9 volt) connector. I powered it using the hub in my computer monitor. As you see a nice switch forces the digital output to be either stereo or 5.1.

Pass-through HDMI connector is naturally provided as well as Toslink, Coax and analog stereo 3.5mm outputs.
Amazon Basics HDMI Extractor Analog Measurements
I started testing by feeding it HDMI and capturing analog output:
View attachment 245856
Not very pretty but hard to expect anything more remotely close to this price point. Output is low by desktop DAC standards but should be enough to drive most amplifiers.
I was pleasantly surprised by the dynamic range being nearly 16 bits:

I could tell there was jitter from the dashboard and our dedicated test shows that and then some:

Linearity indicates some kind of truncation to 16 bits:

IMD test shows high noise+distortion:
View attachment 245860
Paradoxically, multitone response is quite respectable:
View attachment 245864
That is like due to lower output level used in Multitone test.
Frequency response is good:

Filtering of out of band, not so good:

Amazon Basics HDMI Extractor Digital Performance:
I hooked up to the coax output and got this dashboard:
View attachment 245865
146 dB is the ideal performance of 24 bit PCM data and we are getting that. This means that the device transparently passes the digital data from HDMI to Coax with no funny conversion to 16 bits and such. This means you can hook up your own high-performance DAC and get proper analog output.
Conclusions
It is incredible how cheap electronic devices can get despite their complexities. Here we not only have an HDMI extractor but a DAC as well. To have this full functionality ship for total of $22 is incredible. No, the DAC is nothing to write home about but for everyday use it should be fine. And if you need better, you can get yourself a $100 DAC and be good to go. Inversely, you can think of this as $22 to add HDMI input to any DAC with Toslink/Coax input!
I am going to put the Amazon Basics HDMI Extractor on my recommended list. It is an incredible bargain.

but of course it's the usual USB 5.0 V.Power is provided with a supplied USB-A to barrel (9 volt) connector.
FWIWIf the measurements of the 2-channel version are anything to go by, this thing should not be worth its money.

Even "DC" is translated to "CC"! Sometimes "CD" is used, Corriente Directa. AC is translated to CA, Corriente Alterna.In these days where English is the standard for tech components, it's conspicuous to see every label in French and Spanish too. Even "DC" is translated to "CC"!
This is a good point!
Great review!
because it can only pass thru very limited 4k signal.Amazing product. Wow. I voted great as always I am really curious why people voted differently.
because it can only pass thru very limited 4k signal.
btw, are there any extractors, at any price, that can do better than this on the video front?

I am looking for a USB to HDMI extractor based on XMOS chip. Has anyone ever seen something like this.
