This is a different Mixer, but this Pyle brand should work OK:
a.co/d/aArAC2U
This 8 port powered USB Hub works nice:
a.co/d/0XSmXgP
This is the SCART to HDMI upscaler you need:
a.co/d/9rKIpoQ
AmigaKit and Amigastore.eu carry the RGB to SCART cable.

great to see the old Retro machines still going strong.
It's amazing that they work so well after so many years.

Doug, you always come through when I'm trying to figure something out for my Amiga. I was getting Mono and trying to figure out a way to fix it, and sure enough, your video popped up, and you did all the work for me! Great video, and thank you for the solution!
I was flabbergasted how few video capture devices actually capture good stereo from an amiga. I guess most of them are expecting just microphone input or something. Luckily such a cheap and cheerful little device actually captures the stereo quite well!
Thanks for making this video. I plan on making some videos on vintage computers and this has helped me in planning.
Glad it was helpful!
Hi Doug
I would like to tell you a BIG Thanks for this excellent Tutorial. Its very helpful. Best regards. G.
Glad you enjoyed it!
Thank you for this tutorial. I’ve never understood OBS beyond the basic one screen setup. I did manage to get a second screen for my livestream. The one and only time I ever did that. Seeing all the steps involved in taking my recordings to the next level makes me think the most under produced, poorly produced Amiga channel is going to stay this way for a while. :)
Glad I could help! Let me know if you do need help with this kind of stuff
Come on HAM. You do know that it is really about the Amiga and not about the production. Amigan's want to see people using the Amiga. Production does play a part and Doug is very good at what he does but so is Chris Edwards, Stephen Jones, Gadget UK, MikeyG, RMC, Amiga Bill, Adrian's Digital Basement, Retro Friends and many more and what I like about all you people is you are all different and you each bring your own perspective to the Amiga.
The Amiga is unique and so are the people who use them.
@@alanhaynes4576 My friend Q here has more experience in the film field than most people. Just look him up on IMDb someday. His "poorly produced under produced videos" Is just his tagline because he has a fantastic sense of humor.
@@10MARC Yes I get the sense of humour and that is why I subscribe to his channel. One of the reasons I subscribed. Sorry but my comments to Hold and Modify were not meant to cause offence. I was expecting him to come back with something else that would make us laugh. I guess I am getting too old. Funny I don't feel old at 70. Perhaps my sense of humour is out of date too. Never!
The Irish have a saying that used to hang on the hallway wall in my childhood homel: "If you can't make yourself at home here; go home."
@@alanhaynes4576 my comments were about my own channel, not Doug’s. That bit about “poorly produced.” Is my “opening phrase.” for all my vids. I love Doug’s channel and many of the ones you mentioned.
Interesting video, thanks for that! My suggestion for capturing HDMI and all forms of analog signals (VGA, Component, Composite, STEREO-AUDIO(!) etc.) is the USB3HDCAP from Startech (easy to find via Google). I use this in combination with an OSSC for my retro hardware, like Atari ST/STE/Falcon/Jaguar and Amiga 1200. Audio works perfect with it, so no need for extra audio capture hardware.
17:03 You have a VERY noisy audio signal from your Amiga! Normally the audio peak bars are almost left when no sound is played. The Amiga (and Atari Falcon) has a quite clear signal, while my STs are very noisy and ook almost like in your video! 😮
Great tips, Doug! I especially appreciate you sharing about the DigitNow stereo capture. While I have found that my RetroTink 2X-Pro into a run-of-the-mill HDMI to USB device captures the Amiga audio fine, it's nice to know of other, more affordable options.
For example, I found it works well to use the RetroTink for stereo audio simultaneously with the RGBtoHDMI using 2 HDMI to USB capture devices and recording with QuickTime Player on Mac. (QuickTime Player lets the user choose to record the audio from one USB device and the video from another simultaneously.)
You are right - the Retrotink can handle the audio. It does not really work with my A1200 setup since I am using an MK2 for video on that machine. But for my other machines it works ok for grabbing Amiga audio and pushing it thru to the HDMI.
Great explained. Well done Doug.
So glad you enjoyed it! My latest video I have my VGA output from my A3000 converted to HDMI and recorded on that equipment.
Great tutorial Doug! Keep it up!
Thanks my friend!
Although I have no use for this today, cool video! I wish this had been available back in the Amiga days of the late 1980's. I would so have jumped on this for our club instead of our paper newsletter and stuff! Of course, few people had internet access, either, back then. Mostly just BBS dialups.
Back then I suppose it all would have been on VHS tape using a Genlock! That would have been expensive to distribute, though!
Another excellent device to output RGB with audio to HDMI on your Amiga would be the Schubert D520 HDMi Video Converter.
It is an external little box that can be connected to any Amiga on the RGB port .
It doesn't support SUPER-RES though.
They are hard to find these days unfortunately and come at a price, but if you have more than one Amiga and don't want to use a different (internal) sollution for any of them, I would recommend this.
I have heard about this one before, but I have never seen one! Do you own one of those?
Yes, bought one early this year.
I tested it on a 500, 600, 1200 and a 2000
Works great.
But they seem to be out of stock everywhere.
Amazing how something as simple as a tutorial can launch a storm of tinkering -- it's got me thinking about pulling some found AV equipment out of the basement so I can fart around with OBS. Not like I have a UA-cam channel or anything :P
Awesome! Let me know how it works out!
Remember that microphone inputs are not the same as stereo line level capture inputs. Microphones are single channel and the frequency response is often tuned to capture from a microphone instead of just digitizing and saving the signal accurately...
Good advice - and it seems most of the video capture devices only have mic inputs. Even the few I tried with "line in" were mediocre at best
Very good Doug and interesting.
Just a pity that we can't use the Amiga to stream direct to UA-cam. You know cut out the middleman or should I say the PC.
I wonder if AROS has some sort of facility or even the Mac running on Shapeshifter on the Amiga.
Ah never mind; one can dream. Perhaps Morphos on a Power Mac G5 with a pc emulator running OBS.
Great work regardless
Well... The PC is more or less just the conduit to stream the Amiga to UA-cam or Twitch. I have plans for my Video Toaster to allow it to stream. Again, the PC is a conduit but the Toaster will be processing the video.
@@10MARC I was going to mention the Toaster, but I figured as you have one you would have used it if it could do the job. Getting closer to all Amiga but now we need Newtek to make some new Toaster Hardware that will plug into USB and give the Amiga a real USB Stack. I keep dreamin, Doug
nice i just wonder about this and i can found simply solution - maybe i can record the video via dvbt2 tv decoder - but only for capturing i dont't have streaming in my mind
It is certainly worth a try! Let me know how it works out.
Amiga was cool when having 16 million color shades was cool. Mac IIfx color (but not the delicious Tritron square pixels) on a budget.
Today, every computer rocks 32 million...
Sure... But modern computers are so darn boring! Snore fest!
Paula is not stereo. You got 4 mono channels. 2 panned all the way to the left and others all the way to the right. There are players for Amiga that do a trick on the Amiga so you can play back real audio files in stereo but that is something different.
So you plan on destroying 37 years of Amiga superiority by calling poor Paula Mono???
Here is the description of stereo. "Stereo is short for stereophonic. It originates from the Greek word stereos which means solid firm and three-dimensional. Stereo audio has two audio signals designed for two separate audio channels which creates a perception of space."
If Paula does not fit that description by sending four distinct audio channels labeled left and right, I'm not sure what would fit the description. Paula is stereo.
@@10MARC With true stereo sound you can place voices and instruments exactly where you like between the speakers. When you listen to a typical song recorded the last 50 years it is like that. You can even put 2 microphones in front of anything and the sounds will be tree-dimensional. For example a car will move from one side of the speakers to the other. With mono it is not like that. As said, you can trick paula to play stereo but it is really not a real stereo chip. There no Amiga game I know that use true stereo sound. Listen with 2 speakers and you will hear that all the sounds are panned all the way to left and right using max 4 channels. Mostly music in Amiga games use 3-channels and 1-channel is left for sound fx. You might noticed that some times music stop playing cause of a sound fx. That is cause you can give sound priority and if you like a sound fx to have priority over a sound channel it will stop and come back. Quite clever and works well without disturbing the music to much. C-64, SID is mono, 3 channels but not panned to left or right. Sure, if you connect 1 speaker to Amiga all sound will stay in the middle just as any single speaker would playing back music from a CD. Stereo sound came in the 60s. If you use 2 paula channels with a sound and different volume you can place a voice or instrument anywhere you want in the stereo perspective. The problem is that if you use 2 channels for that you only have 2 channels left. That would in theory say that in stereo you will have 2 instruments to play with. That is very limiting. Even 4 channels is quite limiting. When you record only a drum set in true stereo you might use 16 channels. This is partly why they made soundcards and AHI for Amiga. When they did that you had true 16 or 24-bit audio, 44,1kHz or higher sample rate + unlimited amout of audio channels. I think Paula sound fantastic and it is in many ways cause of the limitations. As said before you can so a volume trick with Paula so you can get true stereo sound but that require a lot of CPU power. This was not intended from Commodore but some clever people found a way to do it. Some games ported from PC that use AHI like Doom can so that. If you have CD32 or CD-rom in your Amiga you can of cause have real stereo as you can use the CD audio but that has nothing to with Paula.
@@nikosidis so with stereo music in the '80s, there was no such thing as a "Stereo chip" in things like radios and music systems. There were just speakers and the device sending music to specific speakers at specific volumes. There was not a magical chip that did that. Paula is also not a magical chip that can magically turn everything into stereo. Is a chip that can communicate with both the left and right speakers with multiple channels, therefore producing stereo sound if the producer sends the sound out correctly. Paula does just fine at stereo sound.
@@10MARC I will not disagree about what you are saying but in reality Amiga games or modules are not in stereo first of all because of the channel limitations. You could do some tricks but it required a lot of CPU power. For some strange reason Commodore panned the 4 channels all the way to the left or right. When A1200 came to the market I was pissed they did not upgrade the Paula chip to modern standards. Today I'm happy they did not :) Back in the day I bought A4000 with Delfina 16-bit soundcard. I have bought A4000 back but Delfina soundcard I have not.
@@10MARC I am afraid I have to agree with nikosidis.
Paula has by default 4 mono channels.
Let's say you want to play a sample of a car on a tracker going from left to right, on the Amiga you need 2 channels to do that, one on the left with the volume incrementally fading out and one on the right with the volune incrementally fading in, right?
Whereas in a stereo chip you would use 1 stereo channel panning from max left to max right incrementally.
I think that is what nikosidis is trying to say.
