No.
Cool, Any idea of what was causing it to output audible signal from the case?

Fantastic modules btw, and a killer ethos. Thanks for all your work and everything you’ve made possible :)

I guess a badly inserted cable in the IN input (or faulty cable), causing the tip of the jack to touch the switch could cause something like this.

But given the 10mA limited current drive of a module output, the sound must have been very faint.

Yup that’s it, I just managed to recreate it, that particular cable wasn’t easily inserting fully. Must have not noticed before and thought it was fully insterting each time. User error, again ;) cable binned...

Yeah very faint, same kinda level as hearing a loud set of headphones placed on a desk from couple feet away. Just spooked me today cos I didn’t notice it last night and thought maybe something had broken.

Thanks.

Hello! I am having trouble with the gate output - it doesn't seem to activate unless the gain is cranked all the way up and I hit the module pretty hard. Any advice?

You can adjust the gate detector threshold via the jumpers on the back. See the manual:

Sorry should have mentioned I’ve already tried that! Even with the jumper on 1V I have to hit the module very hard.

Mic question - impedance ignorance

Post by rhialtotm »

I have a lavalier mic with a 3.5mm TRS output cable. made by paladou for use with PC’s/smart phones. Naively I thought that as it has a 3.5mm connector, it would just work with ears. However when I plug it in, I get nothing - even with gain all the way up.

Ears has a Hi-Z input. I found online that the mic has a 2.2k ohm output impedance. I have now reached the edge of my ignorance. Anyone know how I can get this mic to work with ears?

I guess the mic has a TRRS plug and the mic signal is on the 2nd ring (but should be on the tip for Ears´s mono jack socket)?

Condenser-microphones needs power to work.

Larger studio microphones use Phantom Power.

Microphones for portable recorders ets. use plugin Power.

I am not shure if that is the same for microphones for iphones etc.

Expert Sleepers make the module "Little Mikey" that has Phantom Power.
I would love if they made a Plugin Power version, maybe in 2 hp...
As far as I know, such a module does not exist.

Some portable mics have a battery-driven pluginpower adapter, like this one:

If you can get something like that, it might work.

I would buy Ears mainly to generate gates from an incoming guitar signal (single notes). WOuld it be better suited for that very task than Make Noise Maths? Maths is kind of doing the job but it is a bit tricky to set the right threshold...

Yeah, Ears is perfect for that. It has a ton of gain on the input, so it can amplify a line-level guitar up to modular levels to make signal processing much better. The knob on the front controls the sensitivity, and there are jumper settings for the decay.

Maths would be touchy by comparison since you are trying to set the gate threshold so close to zero.

Doepfer A-119 is another relatively inexpensive choice.

it does have a TRRS plug, but it has an adapter that turns it into a TRS plug. Either way it doesn't work. Is there an adapater that will get the signal onto the tip?

Do you know what kind of lavalier mic it is? Most lavalier’s are condenser mics and need phantom power to work...

As I mentioned in my recent post, you need an adapter, that can give the microphone the required power, which I guess is pluginpower, not phantom power. The adapter from Soundman, shown in the link above does that. So you need to find something like that.

quick question for ears owners - i've been looking all over for the voltage range of the envelope follower output, but can't find it. is it 5v or 10v?

Not quite a necro thread ...

Is there enough gain on the input to drive a Sennheiser MD441 - a dynamic mic that needs a lot of preamp usually.
And guitar/instrument straight in is OK? Aren't there usually impedance issues?

Thinking about the usual comparisons with the Doepfer A119 and also considering the Befaco module.

You can go direct in with a guitar with no issues.

Re: Mutable Music Things - Ears module

Hi everybody,
I have a question concerning Ears: It happened that my unit shortened, as I just plugged in a Shure SM58. It has a stereo plug, but Ears has only a mono-jack with a connected switching pin. Anyway, just wanted to ask, as I didn´t found any reliable info about it. Just all the demo-videos I´ve reviewed are showing mono-only-plugs. So maybe Ears is just not designed for stereo plugs? If this is not true, what else could have happened?
Thanks for any hints!

It's not stereo, it's balanced. Is the Ears still functioning at all? There are various ways of wiring balanced cables, some will work with an unbalanced input, as Ears have, some may not. You could try a different XLR to mono jack from the mic.

No, its currently no more functioning, but I will have a look at it to see, if I can repair it. Okay, so I understand you correctly, that plugin in this mic, could maybe cause to destroy a correctly built Ears?
Here is a liik to the manual of the SM58. At the end of it, its principle wiring is shown: https://pubs.shure.com/guide/SM58/en-US
2 and 3 are somehow connected, so I´m sceptical, if this couldn´t cause for the shortcut.

Re: Mutable Music Things - Ears module

I would be very surprised if plugging in any mic could destroy the Ears, there's miniscule current transduced in a mic. Was the cable you used an XLR to minijack, or were you using an adapter? I never like using any kind of adapter to minijack, the sockets just aren't physically string enough to take the combined strain of two jacks and a heavy length of cable.

That's all I can think of, that the input is physically broken.

Any other symptoms? You say shortened, what exactly do you mean?

It was a XLR to minijack cable. The ears was smelling suspect and shutdown. I will double-check it and comeback, if I know more. Thank you for your kind response!
