Hey all,
Not sure if this is covered somewhere else or not, but I can't seem to find it...
Is there anyway to adjust the overall level for the audio in? I don't mean the audio threshold for triggering an envelope, and I don't mean the audio in slider.
Seems to run a bit low on mine...
thanks

Hi,
beside Audio in slider, they are no other settings available.
-
Also checked this with my Minibrute and I can confirm, that the Audio-In-level is very low.
If the Audio-In-level is set to 100% and the volume-level of my Blofeld is set to 100% and plugged into the Audio-In of the Minibrute, I need to reduce the amount of all the Oscillator-sliders to about 15% to 25%, to get an acceptable equal volume of both instruments.
Otherwise the Minibrute's sound is way too loud and killing all of the Audio-In's signal.
-
that's a shame...i guess i will need to run something to add some gain before i input it to the minibrute...disappointing to say the least.
glad i'm not the only one though. my experience is exactly the same as nonserial
thanks for the answer :)
-
The same here...annoying...makes the audio-in USELESS...tried beefing my drum machine up with some drivers en compressors...but still very low levels....please Arturia adjust this in an firmware update
-
i hope firmware can fix it...part of me fears that it's hardware :(
-
No way to change it in the firmware. It's a resistor that must be changed.
-
Ok, I know it's not the top but you needs a preamp for get it a decent gain in audio in of Minibrute.
For ex used a micamp for my mad player and it' s a better lvl that without
-
"It's a resistor that must be changed."
Is it a design fault? Is this gonna be changed in future mini-brutes?
Is there a warranty? Or must I pick up the solder pistol?
I'm glad I didn't get all the other bugs that people are reporting
Happy with my almost bugfree minibrute
so I rather not send my unit back or open it up.......
what to do?

i'm also curious if this is the way it's designed or just a few minibrutes...
really hampers it imho
-
It's by design. The gain as been set so that it "can" handle Modular Synth Outputs (up to 20Vpp). So it's very difficult, with a fixed gain, to handle both a strong modular and a weak MP3 player. I tried to find something that can fit both, but indeed It might be to weak gain for small signals.
The gain is set by a resistor, if you feel that it's not enough for your application, the only way it to hack your machine with a new resistor value. That will of course void the warranty...

When I first got my Minibrute, I experienced either low levels or no levels using the Audio In. Now I get NO levels at all. Would a preamp help to boost the signal without damaging the unit.
Also, can you run both mono and stereo inputs into the Audio in? I know on the Korg monotrons if you run mono you risk blowing the circuits.
I'd really like to process something through the Minibrute filters.
Thanks,
Jeff

Even if the audio in level could be seen as "low", it's should be acceptable in most conditions.
With audio in slider at max, filter in LP, fully opened, master volume at max, on my test machine I have a +3dB between audio in signal level and master output signal level. this value could differ with device output impedance but it should not be too far from this value.
If you have a doubt about you audio in, you can make this test an let me know the result.
Anyway you won't damage anything by using a preamp.
-
Great! Thanks Bruno, I'll give this a try!! :)
-
Works! Thanks for the tip Bruno!! ;D

i allready asked this in another thread, but sadly got no response from the staff.
im fine with the audio in levels, maybe bit to low but ok, i can deal with it.
but what a really big problem is that its not possible on (my) minibrute to use the audio gate switch option properly. if MB is switched to gate and i put a loud signal in nothing happens, the env wont be triggered by audio. The weird thing is, that if i make the audio in my DAW so loud that it clips hard, then the envelope gets triggered. it really weird, because as soon as audio starts clipping (in my DAW) the MB responds. i try this with different signals, usually i just want to route the headphone channel of my interface to the audio in of the MB. But triggering the env only works if signal is hard clipping, this means no chance for me to get the MB triggered by a clean (non-clipping) signal.
i would really apreciate if the staff could be so kind and response on my problem, this is allready the third try to get some info about this problem from you guys. please take a heart and awnser me!
/edit
ive made a short video, maybe this helps understanding my problem

the video is recorded a bit to quiet, please turn up the volume ;)

hmm, seems mine is too sensitive and really easy to peak the audio input causing unwanted distrotion, I am feeding it from a send on my mixer
