Oh nooooooo!!! That’s what I did initially, then figured maybe a separate audio interface would do the trick. I’ve spent way too much time with the Dwarf’s input and output gain knobs on the unit and then separately with the effects in the interface trying to get the pops and crackles down, having mostly solved the ground hum with the Pyle hum destroyer.
Honestly I’ve owned multiple devices like the Dwarf and have never had to do this much tweaking. I just love the Dwarf interface and effects options so much, I figure I’ll give it more time to hopefully work things out.
On the other hand, if I’ve got a defective unit, then no amount of my time is worth it. I’ll email support and see what they say. I’d love to celebrate this device given its potential. Thanks @QuestionMarc .
@dreamer Thank you – I tried both options and couldn’t get the latency where I wanted nor the crackles/pops/hum solved at the same time. Figured I’d spend the time on the latter, as anyway I wanted a separate audio interface for both line and microphone (XLR) recording capabilities. I might come back to this at a later time, just need the sound pollution gone first. Thanks again.
It would be great if we can figure out some better diagnostics for this (seemingly prevalent) issue of noise.
If we can categorize the different setups and find a way to replicate certain misbehavior. I don’t have a Dwarf yet and I haven’t used my DuoX with an amped/PA setup yet, only in the studio.
Will be a few months before I can chime in with some practical experience on this one.
Unfortunately this isn’t really practical. The Cioks DC7 (one of the newer models) supplies 12v at 500ma. It would take 6 out of the 7 outputs from the cioks together in parallel to provide the 12v 3a that the Dwarf requires. I do imagine this would remove the noise though
This is another bummer for me with the Dwarf. If I mount it on my pedal board I’m still stuck running separate AC power for it. There are some power supplies like the Walrus audio ones that have an AC plug on them. I don’t think the power to it is conditioned in any way though.
This is still in development to be stable (and not experimental), but sooner or later it will come.
Regarding the noise issues, have you guys (those facing noise issues) updated your Dwarf and tried the new ground loop compensation feature? It would be awesome if you can share your results
Yup, tried it last night. Since I had put in a hum killer between the Dwarf and the interface already, this feature did nothing noticeable for me. Hope that helps.
Well, it’s expensive for sure! It’s one of those solutions we would employ in a perfect world – and I would do that. Cioks 12 outs PSU is so nice that they even have a 15V port for Radial Tonebone users.
Now you mention the Quad Cortex in your post, and it needs indeed 3A, but does the Dwarf require that much? The Duo X has two displays, one more processor and many more lights and requires only 2A. I’d guess the Dwarf would at most require 2A as well.
This is a good question. I thought I had seen 3A in another thread but can’t seem to find it again. Maybe the MOD folks can chime in… the supplied PSU is 12v 3A, but maybe that isn’t required. If it was closer to 1A that would be great
I just tested out the 1.10.2 build and the “Compensate Ground Loop” setting seems to have no impact. I thought that the 1.11 test build I had (which had that on by default) cleaned up about 75% of the noise. On 1.10.2 it doesn’t seem to make any difference.
Using a cheapo pyle hum destroyer does seem to improve it greatly, although it may seem to suck some tone. I’ll need to investigate that a bit more.
Hi João, I am still experiencing pops even after the update, with either option enabled on the new ground lift menu option (the balanced cables solved the basic noise issues, except for the pops, so I’m leaving it off for now). They don’t seem to correlate with CPU load (it’s running around 68%, there are some random spikes but they don’t cause the pops), and I made sure that the input/outputs aren’t clipping. I’m pretty sure all my gain staging is good. I will try to do some recording tomorrow/Sat and upload it with time stamps or something to highlight the pops, along with a pic of the pedalboard I’ve been working with— Also, my output 2 is definitely a few dB louder than output 1, but that’s easy enough to compensate for, just not super confidence-inspiring. Still having a blast with the board… learning CV stuff, etc. but I gotta say I can’t wait for the looperlative, I’m trash at hitting the loop record button at the exact perfect time and am looking forward to syncing it to the clock easily (trying to use the CV clock to sync is a little weird, I’m still working on making that happen usefully). Thanks.
To be more clear, plugins that update dynamically (tinygain, stepsequencer and the like) are generating some “clicks and pops” when the webgui is open.
This issue does not appear on Duo or Duo X, only on Dwarf.
We are investigating
I hear same clicks and pops even with NO WEB GUI open and USB cable connected. In this case, jack_capture it’s not able to capture them. They’re only audible via OUT and PHONES connections. I will try to record them from the “outside”.
I’ve experienced same clicks and pops when Dwarf is working to save a pedalboard (with WEB GUI open).
A power source that can deliver about 30% more current than the max expected is highly recommended in any scenario. For a tube amp even more so at 50%. That prevents transformers from overheating.
The Dwarf picture from the wiki seems to show the power input at 12V and 2A.
nope, but I do have sequencers running, and haven’t tried it outside of the web GUI yet… I need more midi assigns… I’ll do more experimentation this weekend
Ok I captured a very short clip of my bass through the above pedalboard with basically everything off but the cab, no web GUI, and the pops are clearly audible… to a somewhat distressing degree. I can’t seem to post audio here, can I email it to you?
