Have the known problem with the xmos usb i/o chip. Uir 24 no more recognized, and no more available in my daws. Is it possible to fix it ? Can you maybe show how ? Thanks in advance.
Thank you for doing this, it was extremely helpful. I am having an issue where on a few channels, the worst being channel 14, there is a static/interference noise that is coming through the channel when there is. nothing plugged into it. It registers gain in the preamp section and if you turn the gain up, the noise makes the channel unusable. Have you heard of this issue before and have you ever repaired individual inputs on the unit?
Is there an actual schematic anywhere to be found for this unit? My channels 7 and 17 are out. Tried all the suggestions here and still nothing, so at this point I'd like to check the solder joints but I'm not sure how to identify those specific channels on the circuit board.
¿ Should all the black wires from the power supply not be at the +18V relative to the white? I am getting the white and adjacent black wire at the same voltage. In fact, they are physically shorted. From a color-coding perspective, this seems rather odd!
Great and informative video. My Ui24R has been working fine over the last 2 years and your video has just convinced me „not“ to open it up. It’s nevertheless good to see what’s inside and how everything is wired together. Many thanks.
My UI24 not resetting, green light keeps on blinking forever. I tried different USB Flashdrive (Fat32) still not resetting. I reset because only channel 3 is working the rest don't work. RTA have signal but no sound and no green signal. Please help thanks!
It's amazing that we get to see a tear down and commentary on the design and architecture from one of the original designers! That's brilliant, well done Danny
I have electrocution issues with my ui24r. The body of the mixer and all cables are frying. I've only purchased the device few months back and used for 3 - one hour sessions just to save two basic mix scenes (didnt have the problem during the first two uses). What could be the problem? I could add a ground pin, but I'm looking for a permanent solution than that.
Thanks a lot for the excellent video! I've been using the Ui24r since 5 years - one outage only (related to the wifi settings) - no temp issues as it is mounted in a ventilated rack.
I'd like a little insight....what is the physical differences between a stereo usb recording mixer and a multi channel recording usb mixer? Is it a huge extra expense to offer individual channels as opposed to just sending a stereo bus? It seems that trying to find a small mixer with separate channel usb recording outputs is as hard to find as the challenge I had finding a similar mid level mixer with direct outputs for each 8 channels. I just wonder why with this product range that they only offered multi usb with the 24 channel instead of just putting the option into each. Is it a case of a simple reprogramming of a chip, or a bunch of extra wiring and work? Thanks
thank you for the video I have a problem with the ui24r console I either have a black screen at startup or a screen with the message loading impossible to do a factory reset according to the elements I have seen this may come of the arm card?
Very informative video and fun to watch! How can I find out if I have a potentially malfunction front USB Board or if I have a revised version? If you have a new one, could you point out the changes on HD pictures?

This is a seriously underrated video! Only 160 likes right now (June 2021). Great teardown for anyone interested in these mixers!

are you still making videos?

Excellent video Danny, very informative. Thanks.
You just improved my trouble shooting by 500% Thank you
Thank you so much for this amazing video.
great video. how would I wire mix L and mix R to a 3.5mm stereo jack? Y-cable with 1+3 bridged?

is there a maximum current for the internal fan power supply? can I install and 18W fan that pulls 1.5A?

What was the reason (from engineering perspective) to actually go for an Allwinner SoC-platform (and not e.g. for NXP
