E1DA Cosmos ADCiso Review

[bachatero]

Depends on the purpose.

Measuring DACs

Just received my Cosmos ADCiso and Scaler and it's almost worth getting for the completely awesome packaging alone. It looks like something from Fallout!

Hi everyone, Hi IVX.
I purchased a E1DA ADCiso from Linsoul. It took a few weeks to make it to Australia but i received it earlier this week. However, i can not get it to connect to anything. I took it out of the box, used a USB-A to USB-C lead to plug it into my USB power bank into the power usb-c socket. Nothing happened but i gave it about 20 seconds then plugged into my laptop. The orange LED beside the data USB-C light up for about 5 seconds, then blinks every second or so, but nothing comes up in my windows 10, not even an unrecognized device. I've tried installing the device drivers but it gets to the point of 'plug in your usb device then click ok'. I plug the device in and click ok but reports no device found and to plug device in and click ok. The device driver just gets stuck in a loop. I've tried multiple USB-A to USB-C leads for power and data and 3 different windows 10 PCs. What am i doing wrong? TIA

Hi @AussieDan! Welcome to ASR.

Could you try powering the Cosmos from a wall wart (phone charger) instead?

Many power banks will cut power is the current draw is too low, to avoid trickle discharge. That may be what's happening here.

Thanks StaticV3. I've tried a power bank, 2 iPhone wall warts, a power point with included USB charging ports as well as just using 2 USB sockets on the same PC or laptop

Trying out the ADC-iso grade B on 10 V setting, Channel R
Source SMSL SU-9 pro at 0 dB on vol
Software REW.
Branded normal usb adapter 5v source.

-3,2 dB fs generator rew

The last 20 db at stepped

 

[torgeirs]

Now both channels from DAC into ADC. 3.3volt setting
ADC 100% windows volume
REW to rme babyace 1.gen to SPDIF fibre to SMSL SPDIF in
L+R out on REW

sweetspot


Another sweetspot


Last 6 db of stepping

sweep -6 dB generator


140 db 0.2 dB steps


So my ADC-iso should be inside spec

Actually, many USB-C cables are only for charging purposes, try different DATA cables(short is better) and different USB ports. First, you need to power the right one USB-C marked as "Power it first", and after that, you need to connect the PC's USB to the left DATA USB-C. W10 will see the ADC without the driver installed. The driver needs to be installed manually i.e. point for Windows the folder(driver installer creates that) with the sys file.

Thansk for your reply IVX. I've been thinking all along that its a power issue, but you could be right that im just getting no data from the PC to the ADC. All of the USB-C cables i have are probably just charge cables for the devices they come with and none are data. I'll buy a dedicated data USB-A to USB-C and report back. Thank you!

I have also purchased this just recently.
Using standard windows driver
Using charge cable with micro to c adapter
Using data cable that is a charge cable from nitcore headlamp
Works like a charm.
Some REW crashes though but think that is because of high memmory usage.
And some cases where I have not put the usb c cables into the ADC-iso properly

Do one need to power down for reconnecting to PC or is it enough to just take the signal usb in and out?

The DATA USB is the key, to resetting the ADC replug that cable, that's it.

 

[torgeirs]

Tried also the flex asio driver with wasapi, But not friends with ADC-iso yet. Crash when start FFT. CAn turn on signal on REW
.
WDM is OK

Using WASAPI exclusive with standard non ASIO windows driver. Working OK.
So thats OK for me

64bit REW has Wasapi Exclusive built-in (called Java EXCL there), so there's no reason really to use FlexASIO anymore.

Hi IVX. I went and purchased a pair of USB-A to USB-C data+power cables yesterday and the ADCiso connects to my laptop. Thanks very much for your help!

Hello IXV
Hello everyone
I bought an E1DA ADC and use it to listen to my vinyl records.
I have a phono preamp, so I convert the signal with E1DA, go into the PC, send the signal to Jriver, do processing, and then send it to the DAC.
The problem is that the format of the signal that reaches Jriver is fixed, whatever format I choose to output to E1DA, and it seems that Windows 11 has something to do with it.
How can I prevent Windows from manipulating the signal before it reaches Jriver???

Many thanks and Best regards!!!
Marco

@marcob9999 : What method do you use for capturing the ADC stream in JRiver?

 

[marcob9999]

Hello "phofman"
I simply connect E1DA to a USB input, then tell Windows to take that signal and send it, as an output device, to Jriver.
This way I can also watch a video on the browser and send the audio to Jriver.
The only "problem" is that Windows resamples the signal.
I would like it to only do "the paper pusher": take the input and turn it to output (Jriver) WITHOUT touching it in any way.

 

[phofman]

OK, thanks. Then the question is which audio API JRiver uses for the capture. an audio API which uses internal windows mixer? It would need to use an API which bypasses the windows mixer, i.e. WASAPI exclusive, Kernel Streaming (very complicated), ASIO.

 

[IVX]

that's strange, REW uses WASAPI Exclusive and stays stable even at 768kHz.

 

[marcob9999]

Hello everyone and happy new year!!!
I think the "problem" is that REW "sees" the ADC, instead JRIVER has a virtual input that is seen by Windows, so the ADC enters in Windows which then forwards it to Jriver as an output device.
But Windows asks me with which format (bitrate/frequency) to communicate with Jriver so it converts whatever format it has as input!
I have no idea how to avoid this :-((...
