Schertler Dyn-Uni-P48 Contact Microphone

I was looking for a really good quality contact microphone for field recording purposes. The 3 options I considered are the Barcus-Berry 4000 Planar Wave, the Trance Audio Inducer and this one.

I haven't managed to try the other 2, but this one does have a great sound quality. It has a very low noise and a very good overall response. It's much richer than the AKG C411.
And it doesn't need a special pre-amplifier like the other 2, which makes it light and easy to take with me.

I bought this guy with some great expectations and they all were satisfied, with some astonishing surprise.

The cutting-edge design allows for it to be easily stuck on any kind of device (giant, big, long, thin, tiny, small, thick, resonant, smudgy, dull, solid, wobbly and more!)

Sound quality is no-compromisingly superb in that handling noise is zeroed, as well as noise floor. Spectrum is flat, gives a really natural feeling once you hear back from it. It really let you hear from the inside of any device. Maybe works TOO well? Don't think so.

That said, the only bug in the cup is that since it has no pre-eq it comes as an extremely sensitive mic, that means you better place it carefully when you're dealing with consistent bass frequencies that might easily bring annoying physical distortion on the unit (no post HP helps here), ruining your recordings, with almost no-way back. So, find the sweet spot even before pressing REC ok?

And now... The breakthrough: This device is capable of detect ELECTROMAGNETIC FIELDS! You know what that means? Perhaps a little risk of re-introduced hum (it doesn't have on its own) but a whole set of creative opportunities (e.g. try to place it next to smartphones or monitors... Yes, you know now!).

So, in all aspects, a great unit. Highly recommended for pro-recordings. Not the best choice if you're on a budget.

Ich hatte schon länger mit dem Dyn-Uni P48 überlegt, da mir ein Kontaktmikrofon eine optimale Wahl scheint, um ohne "Außengeräusche" aufzunehmen.
Das Schertler Dyn-Uni-P48 macht diesen Job im Ersteindruck sehr gut.
Ich sende es jedoch zurück: Leider ist das Gerät sehr anfällig auf Störungen aus dem HF-Bereich (Funkstörungen): Ich hatte ständig Handysignal mit auf der Tonspur und bei Neonbeleuchtung auch das hierfür typische Summen (in dem Fall aus 4m Entfernung!).
Ich hab echt an mir gezweifelt, aber als Ursache erwies sich das Dyn-Uni-P48: Mit der Rückseite kann man - bei Bedarf ganz gezielt - Aufnahmen von HF-Störern machen - einfach mal ans Handy oder irgendein Netzteil halten.
Wer also "die leisen Töne" - (bei hohem Gain) benötigt, sollte sich hier nach einer weniger störempfindlichen Mikrofonierung umsehen.
