Title: Binaural mics - lowcost solution
Post by: kleiner Rainer 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?

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.
