Zoom H1 Crackle

Hi guys,

I am having some issues with my Zoom H1. Recently it has developed a distinct crackling noise during recording. Sounds like it might be electrical. I've updated the firmware but it made no difference.

Here's the link to a sample recording:

Is it possible for someone to let me know whether this might be fixable, or if my H1 is dead?

Thanks.

In the words of Number 2: Information. We want... Information

You haven't provided enough background information -- what settings were in use, what environment you were in, how was the unit supported.

Has it been used near moisture spray? (Close mic'ed to a spitty singer). Condenser elements are quite sensitive to moisture. Bounced around in a shirt pocket (I'd expect a few more thumps if recorded while bouncing around, but...) that may have jarred the elements.

Since the level controls are in the digital realm, it isn't a case of noisy potentiometers (I've had radios that snap/crackle/pop badly until the volume control has been swept back and forth for a few minutes).

Unfortunately, the nature of these devices is such that even Zoom probably doesn't really repair them -- beyond obvious damage/loose wires on the elements themselves, the rest is likely a circuit card swap while under warranty. Zoom does not make parts available, so any general radio/TV repair shop would be limited to maybe swapping in similar microphone capsules, and looking for broken solder traces (though with SMT, even that isn't easy).

Hi Daveozog, :rock: Your post is seen. Why do you think you don't exist?

Your previous posts concern the G5 pedal. Not many forum users have the pedal. I don't and have no interest in the pedal so i don't respond to G5 pedal posts.

OK, sorry for the limited info.

Unit was in my bedroom, on a small flexi tripod. Input level of 60 (crackle is present at all levels of recording). Unit hasn't been exposed to any moisture, nor has it had any rough treatment since last used.

I'm thinking this one might be for the bin.

Cheers!

Out of ideas then... If it were an H5/H6 you'd have been able to test the capsules by swapping the microphone plug-in; but not on any of the other units (the H2/H2n could partly test by changing from front to back elements, but if the all the elements in the unit were involved that wouldn't prove anything)

Thanks for taking the time anyhow :)

As already mentioned above, the capsules are susceptible to moisture. Try placing the H1 in a plastic bag with some dried rice for a day or two, better would be silica-gel bags, but Rice isn't too bad. This should pull any excess moisture out. Not guaranteed, but it's worth a try.
