Binaural mics - lowcost solution
« on: May 10, 2018, 05:08:18 AM »
Hi all on the old world side of the pond

Thomann has a special offer for Roland binaural mics:

https://www.thomann.de/de/roland_wear_pro.htm#

The mic was designed for an older GoPro camera model, but modifying it for recorder use is straightforward.
If you remove the special Mini USB plug, and connect a 3.5mm stereo plug, you lose the warranty, but you get a very sensitive low-noise binaural mic that operates with plug-in power.
My quick-and-dirty test setup with a PCM-D50 worked very well when set up with my trusty old Sennheiser head (the mics it came with degraded too much after 30 years of outdoor use). There is a bit of wind sensitivity, so I have to find a way to improve the wind screens. I had to switch on the mic attenuator and set the gain to 5, but the sound is great. The sensitivity and low noise floor should be of interest for the nature sound crowd. Operation with a battery box seems possible.

FIY: the red wire is the right channel, yellow the left. Both wires have a separate shield.

Executive summary: recommended hack!

Greetings,

Rainer

Hey man, can you translate the approximate cost in USD?
Also, is that a USB C or mini USB connector?

When you get confused, listen to the music play!

Here you go. US settings (I hope).

It's mini USB.

^^^^^^^^^
Thanks, I guess I could have done google translate- so thanks for sure for doing that for me.
So, less than $20 for these + $36 for shipping? Seems like a deal but not sure how one would connect/power them without a gopro: plugin-powered via GoPro Camera (no Batterys required)
I'm interested but no interface for using them with our current bitbuckets.

Thanks for the tip, too bad they don't come with a microUSB plug as they could probably be used direct with an Android smartphone. I wonder how they would hande loud noise, the Roland CS-10 EM aren't great for that.

EDIT - Ok, ordered ! Will be looking to use them with my Zoom H1 as a use GoPro 3 goes for a lot more than I thought it would ! Will go looking for a jack on eBay or Amazon...TRRS so overkill and pretty ugly but no soldering, would this work : https://www.amazon.co.uk/Cerrxian-bornes-femelle-adaptateur-convertisseur/dp/B06XSD95TC/ or this might even be better https://www.amazon.co.uk/CERRXIAN-Terminal-Headphone-Converter-Adapter/dp/B072N8GYSX/ ?

So it just came in. Nice comprehensive package with many tips. So as expected that MiniUSB adapter is not standard. So now I have the choice between getting a used GoPro 3 or a 3.5mm adapter and use it with my H1...unfortunately it doesn't have a limiter so I'm not sure how well it would work, hum...

Try this on your android phone.  You might also get it to work with and adapter and an OTG cable

Interesting thanks, might give that a try before I butcher the cable then.

EDIT - probably won't work (like my current miniUSB to microUSB adapter) because the GoPro uses a 10 miniUSB port : https://www.tapatalk.com/groups/goprouser/hero3-mini-usb-10-pin-t9625-s10.html - doubt there are adapters for that and can't see how the Android would be able to figure out what do with the input...

Ok I'm up and running !
Got this TRRS plug adapter on eBay https://www.amazon.co.uk/Cerrxian-bornes-femelle-adaptateur-convertisseur/dp/B06XSD95TC/ as I couldn't find the TRS version but I thought it might work...and it does ! It was a bit fiddly and required a few attempts  (could only get one channel for some reason) as the cables of the microphone are very thin.
Plugged into my H1 and will now be experimenting, thanks for the tip ! A lot cheaper than the Roland CS-10EM (that also act as headphones of course but have no use for that) to experiment with binaural.

So I've been experimenting with various eartips and over-the-ear mounting and it's been good fun. The microphones are indeed very sensitive ! Here's an example of a quick walk in the rain last night : https://archive.org/details/ZOOM0036_201806
