Qudelix-5K Bluetooth DAC & Headphone Amp

Thanks! I just did
I cannot say i understand it in and out yet but from the mixbus video and looking at their page it looks like a Preset collection based device and only 3 bands of Eq for some minor customisation but i see not PEQ functionality somehow. So its kind like „you better have one of the headphones in the Supported List“
Unless i missed it?

Weird, never thought I'd see Digitakt mentioned here (presumably you mean the Elektron Digitakt 2 sampler/groovebox).
The Digitakt 2 does not only output analog audio. It also has USB Audio out.
In the Settings -> System menu, go to USB CONFIG, uncheck Overbridge and check USB audio/midi.
And then in Settings -> Audio Routing menu, set USB OUT to Main.
It's class-compliant, so you don't need any special drivers and it should support USB Audio Class 1.0 and 2.0. So unless I'm incorrect, you could in fact use the Qudelix as a USB DAC. Or many other devices, as long as they don't need USB power. You'd also need a USB-B to USB-C cable (or USB-B to whatever cable, USB-A).
Like you could use an iPhone too, and then use an AUV3 plugin for parametric EQ, and an app to host AUV3 plugins (like AUM etc..). You could then use bluetooth that way
It also has USB Audio input, if you wanted to route it back into the Digitakt 2 after EQing and use the analog audio output.
The Digitakt 2 outputs 24bit 48kHz, so you'd set that on the DAC/device if needed.
Hi and thank you!
I see the thread has …. Unraveled in a different direction.
I don’t want a way to use a USB output.
The Digitakt was merely the tipping point that made me realise i want this type "In Line" of device.
It was not because it cannot handle Usb. Forget about the Digitakt. I got lost in translation and expression of my question.
I want something like the MiniDsp HA-DSP
Or the Ik multimedia Arc On Ear (this one does not have a flexible PEQ unfortunately), both of which have Line In.
I know it sounds hard to believe but I want something that works on a line output. Be that of an old stereo system with analog outputs , walkmans etc.
I can use qudelx,digitakt,analog heat, computer,audio interface as Dac’s already.
I need Line In capability and the device receiving it being able to apply PEQ correction internally. All of this in 1 enclosure-device

I am aware by now. I spend a considerable amount of time searching and only found 1 that does all of this and it is discontinued ….lol
The MiniDsp HA-DSP. can (better said, Could) do everything i want but it is out of service for a long time now so i would not want a device with a fried battery and no
software support anymore.

the Motu Ultalite-mk5 has built-in parametric EQ and many line-ins
The Mk5 has a 3 band basic Parametric Eq on the headphone output. Also it is hugely overkill for the job. I might as well take my laptop and the mk5 with me everytime i
want to use my headphones on an analog source such as a cassette walkman and similar. I can do literally anything i want to the frequency response using
these two. Only then i have a 1,6 Kilo laptop and a 1.3 kilo interface. So around 3 kilos of equipment and 3k worth of Hardware in order to correct my headphone
on the road…. Might be a bit impractical. Just saying
I don`t know why people (not talking about you but in general) suggest to me solutions that are nowhere near what i am asking. which is

DrSpan said:
I just want a relatively compact „all in one enclosure“ amp that i can connect to any headphone socket i will encounter in my life and have it adjusted to my cans and ready to roll.“
Conclusion is, the only portable, compact and practical device there is, is the MiniDsp HA-DSP which doing exactly what i want and no second choice on the horizon.
The MiniDsp is discontinued so there goes that.
However the reason it exists in the first place is because at least someone else except me wanted such a solution. Not many people seem to want one though.
So for now there simply is no practical solution to my wish. It is a luxury problem i know.

and 4 band EQ on input channels, so 7 total for one input->output
yeah it’s overkill, so is using an ad/da with dsp EQ on a fucking Casette Walkman lol.
You should describe exactly what you actually want next time instead of wasting my time. I don’t even own a Digitakt 2, I downloaded the manual and everything. Whatever
My friend it is your choice what you do with your time.
Discussions evolve and so do our thoughts and tasks at times. I am not a machine that knows 100% what to say every time
Nobody forces anyone to participate last time i checked. If i would count every time i tried to help somewhere only to
find out it was for nothing …. It is like this sometimes
"yeah it’s overkill, so is using an ad/da with dsp EQ on a fucking Casette Walkman lol.“
you miss the point where it is about correcting the headphone response and use this correction on a Line signal and not about the walkman, like at all.
The walkman is a random example of a line output. You can replace walkman with anything that has a Line output.
No need to get so worked up about it. It is not your problem after all
Still thank you for the effort and try to help.
Cheers
My approach is a bit different from your query. Solution would be two devices technically, but it doesn't really look like it.
So, keep you Qudelix 5k and stick this (or smth similar, this was 2min google search for dongle) into USB c side of Qudelix.
Hope it will work for you.
Cheers
If this Sonos adapter works, that would be a great find !!!
But I doubt it... It's most likely using an off-the-shelf ADC chip with an integrated UAC1 or 2 "client" interface. It would need to act as a UAC1 "host" to work with the 5K.

Thank you.
To your suggestion i doubt it will be this easy. I forget the technical term now „proprietary, Hub bla bla usb“ , In short, i don`t think that this will convert
line to usb with the Qudelix. You will need a phone or some other kind of processor. Of course i would absolutely love to be wrong cause this would be a superb compromise for me.
thats what i think. I lack the technical info to back my assumption though.If this Sonos adapter works, that would be a great find !!!
I believe these kind of adapters need something with a bigger brain than the qudelix on their usb side
„Host“ thats the word i needed.
Yup, you're right. Your doubt is definitely reasonable. There's a slim chance they've integrated USB host controller.If this Sonos adapter works, that would be a great find !!!
Looking further, closest thing to proper controller is probably some hub.
Maybe, addition of smth like this in the chain might resolve host/client relationship?

If it doesn't run an operating system, then it can't mediate between Qudelix and Sonos adapter.
The device you linked does not run an operating system.
This is not a HUB the way i see it. In my logic this is the same as the Sonos. Accessories
Finally, I have sufficient time to explain myself.
Apologize for the wall of text, TLDR is available at the bottom of the post.
You are completely right about mediating OS acting as host between Qudelix and ADC stage found in a couple of devices I’ve offered.
I’m aware of that, but my intention was to offer additional search ideas to members with more technical expertise in this area, and to enable them to, maybe, find a working solution. Sort of using ASR as Hive mind, for checking upon my ideas, in order to minimize research on technical side. Unfortunately, I have free time as much as I do, and I’m trying to optimally use that time (including other topics I’m interested in). I understand that this is offensive (especially Hive mind reference, as one of the members on this very thread was offended, couple of pages before this one), and I apologize to members that are feeling abused, it was not my intention (please tell me if this a bad practice, so I’ll stop doing it). Intention was to offer ready-made simple solution available in consumer electronics market, without a need for additional customization and/or extensive DIY.
I find OPs question to be a fun thought experiment, although I struggle to find a use case for myself. Question kick-started following train:
OP needs PEQ? It could be analog or digital:
- Analog box would probably require physical controls, which would probably add substantial bulk, which would then render solution useless in portable scenarios. On the other hand, as an analog box, it is quite possible that analog input is already built in.
- Digital solutions with sufficient portability exist. It is venerable Qudelix 5k and couple of Chinese manufacturers, notably FIIO. Portability is more than sufficient but is missing analog input stage. Let’s see if I can find sufficiently small analog stage.
This is where I started posting and offered ADC dongle as an idea.
At this point it became obvious that additional component is needed (although ADC dongle is capable of sending upstream digital data and Qudelix is capable of receiving stream on the other side), to make a connection between these two devices (as you and other members kindly noted). This component should act as controller with internal logic (mentioned OS) that will facilitate handshakes from both devices and create connection between them.
I suspect that in above-described scenario, PCB would be quite small and even commercially available, and OS would be pretty lightweight (as it suppose to process quite limited set of instructions). Unfortunately, existence of such OS (internal instructions, presumably on a chip) is pretty much questionable.
So, this is it, I didn’t have time to research on such controller (as I was writing this), but if I find something I will follow up on this thread.
On the other hand, this thinking is limited by goal posts set by OP (commercially available ready-made portable solution, please @DrSpan correct me if I'm mistaking). If I were in a similar situation (as I’ve said, I struggle to find a use case), I would probably go Raspberry Pi way. I saw a beautiful post (not sure if it had dedicated thread) on ASR, where a member describes at a low level, how to use Raspberry PI and Camila DSP for room correction.
TLDR: I’m sorry for posting non verified suggestions and I will not do it again. At least not without a disclaimer at the beginning.
If I had a similar requirement, I’d build Raspberry PI for that.
And a disclaimer for the end:
