I am obviously doing something wrong. I still haven't figured out how this web interface works. Actually when I connect my Mac to 192.168.5.1, and the interface appears, any command I send (like assign analog input, or change LP filter value from 0Hz to 20000Hz) doesn't give any confirmation, the box stays open forever and if I check the wifi connection, it shows that Aurora disappears temporarily. I tried to change presets, but get disconnected immediately. When I reconnect and look into parameters, they haven't changed.
What am I doing wrong?

If possible, for future production runs, please use analog header connectors with gold-plated pins instead of tin-plated. The 3M cable connectors I'm using from Mouser (not much selection) have gold-plated contacts and it's not a good thing to have gold mated against tin. Shouldn't be a major issue, especially since I'm going to lube the pins with DeoxIT, but it's an easy change for the better.
EDIT: Digi-key says the mating contact finish is gold, but this doesn't look like any gold I've seen: Access Denied Also looks like tin on my board.

Help with power supply
Hi all, I got my Aurora board and Im excited to finish the build. Im a software engineer though, and I dont now much at all about the hardware! I'm trying to learn as I go but I am really concerned about getting the power supply wrong and blowing the board.
1. I'm super confused because the docs I downloaded from Auverdion seem to say 12V are required but everyone on this thread seems to be saying 7-9V.
2. Also I don't see any mention of amps required anywhere.
3. The last thing Im not sure what to do with is the fact the power molex connector has four wires but my bench power supply has only two. Are there two separate circuits that need to be separately powered, should I leave one set of the wires unpowered, should I tie these two connectors together?
What I want to build out here is a 1U rack case with a standard rack (three prong USA) AC power cable connector on the back. I want the LCD display and the rotary encoder, and I have the 8x8 balanced I/O module, if that helps gauge the power requirement. I have no idea what to buy or how to wire it up, if anyone could recommend a power supply that would fit in 1U and explain how I should wire it up I would be very grateful!

Hi all, glad to see this forum is still active! I got an Aurora DSP from Auverdion in Sept and I am having a little trouble understanding how to safely power it for my application. Bear with me, I'm a software engineer who barely knows anything about electronics.
What I would like to do is build a rack case for this unit with a USA standard 3-prong female AC cable connector on the back, and I have the 8x8 XLR I/O board. I am confused about the power requirements because the PDF on auverdion.com says 12V, while several posts here refer to 7V-9V. I dont see anyone mentioning how many amps should be supplied. Also, the 4-pin power connector on the board appears to have two sets of leads. Im not sure if these are separate circuits and I need two power supplies, or if I can leave one unconnected, or if I should tie the black leads together and the white leads together?
Would love a recommendation for an AC PSU that would fit in a 1U rack case and takes that standard cable, and a little help understanding how to wire it up to the 4-pin molex for the electronically challenged.

Download the latest version of the user manual (should be 2.1.0 or later). It will tell you that you need a single-rail power supply with output between 6 VDC and 10 VDC. For myself, I plan to use a Mean Well RPS-30-7.5, but that is not a rack-mountable unit, just a PCB unit that needs a chassis.
You can feed up to 8 amp channels with the Aurora since it has 8 line level channels (either single-ended or balanced, but not both together). Your speaker requirements will determine how many amps you need. A standard stereo configuration requires 2 channels, 1 for left and 1 for right. An active stereo 2-way configuration would require 2 channels on left and 2 channels on right, ... etc. Note that the Aurora is limited to 1.5 Vrms output so amps with limited gain may not be able to get driven to full power (check the "input sensitivity" spec).
I believe the two black wires can be connected together and the two white wires can be connected together. According to the mini-schematic under the Power Supply heading (page 21 on version 2.1.0) both whites are +12 V (nominal, not actual voltage) and both blacks are ground/common.

Thank you very much for the help! I have completed what I think the majority of the hardware wiring. I have an LCD hooked up, the rotary encoder, everything seems to be working EXCEPT I cant get any sound of my unit. I have the Balanced Life add-on. I have configured that in the web app. I have tried multiple XLR ins and outs and both the 8-channel and the FIR filter plug-ins. The only sound the unit makes is a click on boot or when I save the settings in the Config Device portion of the web app. I'm out of ideas here. Is there any way to generate a test tone? Any other thoughts? I'm starting to wondering if my board is bad. Would anyone be interested in helping me troubleshoot? I am happy to send pics of my wiring and walk through anything, at this point its a lot of time and money invested to have no path forward.
You can email the main auverdion address or maybe the freeDSP address for support. Barring that, there's a German forum that's more active w.r.t. the Aurora board.
It's disappointing but there's a surprisingly small English-speaking community, and relatively little manufacturer engagement, for this product. It's a niche one but nothing else quite ticks the same boxes for its price.

I had a similar problem, but upgrading the firmware to 2.1.3 and reloading the programs resolved the problem.
Apparently having such high uF means that since the corner frequency is significantly below passband, there's no developed voltage across the capacitors and therefore no distortion.Why 100 uF? Haven't the faintest. 100 uF with 10 Kohms input resistance yields a -3 dB corner frequency of 0.16 Hz, whereas 2.2 uF at the same input R is closer to 7 Hz and 4.7 uF is about 3 Hz. The -1 dB points are an octave above the -3 dB rolloff so there might be a slight advantage to the 4.7 over the 2.2 if you want to hear blue whales

@meener777, is your unit now playing after the software update?
Btw. a common mistake is, that users do not raise the master volume slider or forget to save the preset with the new slider setting. Aurora boots with a low factory default value to avoid damages.
@all If you need support you can always write me an email. I don't have the time to scan all forums 24/7. ;-)

Damn it! I booted up my Aurora for the first time and gave it my home network SSID/password, and also put in a password for the Aurora's own network. I rebooted it and now I can't connect to the Aurora's network (I wanted to find out what IP it ended up getting from my router). There's a chance, however unlikely, that I fat-fingered what I thought was the password, but I'm worried that it broke something.
Guess I'll email the support address and see what happens
EDIT: Nope, in the 30 seconds it took to enter the password to set it and then send an email to myself with what the password I set was, I managed to forget the password, hence emailing myself the incorrect password. Sigh

That makes sense. The horrid results from ceramic coupling caps in the audioXpress article indicate low impedance isn't a complete panacea, however, and I wonder how distortion would fare as electrolytics age.
Right, completely forgot about that. Thank you!
For what it's worth, I did manage to remember the correct password
