GroupDIY Clone U87i with pattern problems
« on: July 18, 2019, 05:23:46 PM »
Hello,

I've just finished an U87 clone following the great instructions here, with Microphone parts capsule, styroflex and . Apparently i did everything right, calibrated the FET and so on.

So far the cardiod functions very well, nice sound as expected, but i see no sound change when i change pattern figures. The sound remains around the same with strong signal in front of the mic and lower in the sides and none in the back, even in figure of eight.
Omni also has a lot more signal in front than in the sides or rear.

What should i do?

Thanks

Have a good day

Leandro

Discovered the problem.

The capsule i've order from Microphone Parts is not with separated backplates. I'm returning it.

That was my first thought upon reading the first post.

Aaaaand that's why that project should perhaps have stated in big red lettering, nice and visibly, that you need a special capsule for it...

But hey, it's better 'cause it's "vintage", because the later version is the spawn of the devil, isn't it? ;D And people get easily sucked in and run into problems like this :(

Discovered the problem.

If they won't let you return it and get the double backplate one, get it from WGTcenter. It'll cost you $50 USD or less, but it's the same capsule.
