Where can I find the users manual for the E1DA Cosmos ADCiso and the Scaler

[Deleted member 94338]

I just recently purchased these devices from Linsoul for testing my audio gear. I have extensive experience in using REW and a Benchmark ADC1.
I am now transitioning to these new devices because I'm limited by the noise floor of the ADC1.
I am using a windows 11 laptop that I've used for over a year for interfacing to REW and hardware. I've been using REW for 3 years.

I have looked everywhere I could think of and I just cannot find any instructions at all for either device.
I have hooked the ADC up and I can connect in Java, but not ASIO. I do not see any lights on the front or on the back of the unit although I'm supposed to see a green light for stereo.
I am powering the ADC from a power strip that has a 2.4V USB port for charging. I've tried powering from the laptop, but came result.

With 100mV 1KHz input, I see the peak, but the noise level jumps up and down from -130dB to -40dB continuously (Java).
I am by no means a rookie, but I'll be darned if I can figure this thing out all by myself.

Is there some app or exe I can use to control the functions of the ADC?

Please help!

There are couple of threads with lots of info, here's the review:

E1DA Cosmos ADCiso Review

Yes. Only the native macOS volume control will adjust modes, not (usually) the sliders inside applications. Where you adjust the macOS volume (MIDI Control Panel, Keyboard Vol Up/Down keys, etc) doesn't matter. Thank you so much for the reply! Here are some other questions that I have...

This is the closest thing to a manual -> https://e1dashz.wixsite.com/index/cosmos-adc, it talks through ASIO and drivers.

Thanks. I've already tried both. Not much help there.

I can't get ASIO to work at all. Java does work. What am I missing? Is it necessary to use ASIO?

I am totally frustrated. What good is a piece of hardware if I can't use it? I am tired of downloading this and that because somebody's blog said I should. Why can't the manufacturer clearly spell out what's needed and how to do it?

I realize that writing manuals is boring and distracts from the fun. But if you're going to sell a product, you need to support it with clear, easily accessible instructions.

The lack of a manual destroys whatever performance advantages this product may have.

Hi, I recently bought an ADCiso myself and am learning as well. I don’t have as much experience as you but I’ve managed to take some measurements with it, some even today (check my post history).

The page that mdsimon linked isn’t someone’s blog but it’s basically the product page for the ADC. I agree with you that everything could be better documented, and actually that’s one of the things I intend to do once I’ve become more confident at using it.

At the moment I don’t have any knowledge about the driver situation. I’m using a Mac and it recognizes the ADCiso natively, although it lists it as “recording device”. In REW, there isn’t an option for me to play around with the different drivers as well. For mac there is no driver option it seems. REW also sees it as “recording device”.

some important things to note when using the ADCiso:

- make sure you plug in the power first before connecting the data. Very important that you follow this step

- check that you have selected the appropriate sensitivity via the DIP switches at the bottom. I’m on mobile right now so I can’t give exact values but basically you select the closest option that is higher than your input voltage. E.g. if your input is 4.2Vrms, you would select the 4.5V option.

its late at night for me now so I can’t help more but hopefully those are sufficient starting points for you

Edit: I saw you asked about the scaler as well. I don’t have a scaler yet (am planning to get one once I’m more confident with using the ADCiso) but it seems that you use it, you would need at least one 3.5mm TRS (or TRRS, doesn’t matter since the R and S are both ground) to XLR cable. When you get one, you need to check that the pin outs for the 3.5mm match the diagram on the scaler. Some sellers have their tip and sleeve shorted together for an unbalanced connection, which is what you don’t want.

Scaler has an auto ranging function. I believe the default is 4.5V? But you can set the target output level of the auto scaler. Once you know the output voltage, you can just set your ADCiso sensitivity to match that and not have to touch it anymore as long as you’re using the scaler. Again that’s as much as I have figured out as I haven’t acquired a unit of my own yet.

Yeah, very similar experience here. I also had a terrible experience with the QA403. Horrible, bouncing noise floor. Unusable. No fix available. The retail seller said to look for the latest software. Did. Installed. No difference. I returned it and was socked with a 25% restocking fee.

Figuring how to get my test equipment to work properly without documentation is not a good use of my time. I have far more valuable ways to spend my time.

I've had my Benchmark ADC1 for 13 years. Never a problem. Worked from the beginning. Clear instructions. But it is getting a bit noisier. I need to see events below the noise floor of this unit. These two units, the QA403 and the Cosmos ADC claim to offer that. But since neither works properly or requires downloading some questionable software, I will still rely on my ADC1.

If it helps, I didn’t have to download anything extra for my ADCiso (got it at the start of this year) to work.

Just plugged it into my mac and REW recognizes it. I’m also not using Windows though so I’m not sure how helpful that is

 

[mdsimon2]

You say ASIO is not working but what does that actually mean? What operating system are you using? Which ASIO do you have installed?

Hey, thanks for the useful suggestions. But....

I have written this piece of hardware off as a bad buy.

I will no longer spend countless hours searching for arcane plug-ins and whatever.

There's no need to reply. The boxes are already in the trash bin.

Looks like I'm late seeing this, but here's a link to a page of the ADCiso that has useful info, in this case specifically the link to the Windows driver:

"The driver is required to update the firmware, to unlock the Cosmos ADC's ASIO interface, and to unlock Mono/Stereo control via Windows' default volume slider in the Sound Control Panel."

Thank you for this! It will definitely be helpful if/when I do start using Windows to take measurements again

No plugins of any kind are required to use Cosmos hardware.

A driver and Tweak utility are provided on the product page to give more control over the hardware, but they're in no way essential to the Cosmos' function as measurement equipment.

It can be used plug-and-record.
