General Discussion / Re: Sound input issue on gecho v1??
« Last post by mario on February 21, 2024, 07:13:10 PM »
Glad that this helped! 8) It's a surprising behaviour indeed but it happens because of the analog preamp, which does not operate well with lower batteries - while the rest of the circuit, which is digital, is still fine. It's designed this way, as a low power device it is trying to squeeze most from the batteries, which might still be useful when you don't need microphones. But ideally there should be a low-voltage detect and indicator.

Thank's for your answer, my gecho V1 (wood box) is powered by batteries and you're right, I have just change it and it's work perfectly...

I really feel dumb...But I didn't imagine it could be that. I changed a lot of time batteries in it and I never noticed this sound problem ^^

Gechos are definitively my favorites tiny-swiss-knife-sound-engine!

Cheers!

Hi David,
How are you powering it? Any chance there is a ground loop? I guess most likely from batteries but maybe you use ReVolt for PO and then power both devices from USB, that might cause the issue.
The hum may also be caused by low batteries in Gecho, maybe try USB power to see if anything changes.
V1 uses a separate pre-amp while in the V2 input signal goes directly into codec chip, so it's quite normal that the behaviour differs this way.
Feel free to send a short video or audio recording - I might be able to tell more by the character of the sound.
Cheers,
Mario

General Discussion / Sound input issue on gecho v1??
« Last post by DavidBrittany on February 16, 2024, 05:43:59 PM »
Hello It's a long time I get the Gecho V1 and it seems that input-line (pickup) has some sound issue...
I explain:
when I plug some device like a pocket operator I hear a big "hum" sound.
I don't remember that in the beginning.
I have put the last firmwire and i have done the reset preset (4321).
But always the same electrical-buzz sound...
On my gecho V2 there is no problem, devices plugged with the same cables and devices are quiet.
Some ideas?
Thanks,
David.

General Discussion / Re: Gecho LoopSynth input biasing to Right Channel

Hi Michael,
If I remember correctly there isn't such setting (might be a good idea to add it 8)), however if the inputs were set to some of the modes, which only use one channel, signal from the other one might still be leaking in. To rule this out you can check input configuration (B4 during play) or even easier, to be 100% sure just reset all settings using 4321-SET command - hopefully that should sort it out. You can also try different headphones to be sure it wasn't a faulty cable or something. If it is indeed a hardware problem, no worries, we repair everything for free, regardless if the official warranty expired or not. To arrange a return, please email me to discuss the details (we have changed the address since).
Cheers,

General Discussion / Gecho LoopSynth input biasing to Right Channel
« Last post by Msmiley78 on June 23, 2023, 05:10:55 PM »
Mario and all others,

I have had my Gecho for quite a while now. Just recently I noticed that the input is severely biased to the Right channel. There is some sound coming into the left, but faintly. I'm wondering if there is a channel pan setting that I can check. If not, could it be something internally that has gone awry. If that's the case, can I buy a new board to replace it? Thanks a ton!

Just running into this as I'm pulling a lot of my serial interfaceable gear out to see what it all says to my computer. I use my Teenage Engineering OP-Z with the Line Module or you could use the OP-Lab Module installed to send midi instructions to the Gecho. Using one of the pages on the OP-Z I'm able to use the 4 pots via 4 pages of settings on the OP-Z to manipulate the MI Clouds to its fullest, although only 4 settings at a time, then paging through to adjust the others. I have taken this out because it only requires the 2 device and one TRRS cable and then of course a recording medium. All the best.

Hi Pablo,
that sounds awesome!
there seems to be a problem with the link, maybe the design isn't public?
(I'm not familiar with how thingiverse works, just my guess)
Cheers,
Mario
