EQU47 Mic Bodies | Orders open on January 19th 2013

When we do the next run, my goal is to re-design the end connector to use an equally high-quality amphenol/tuchel connector which will be less expensive and more readily available to you guys.

Will this be the same pattern of connector?

Good to know there will be patch #3

It won't be compatible with previous EQU47s, but if a new connector ends up being used, I'd like it to:
• be at least 7pin or more
• rated for 250V / 3A+
• screw-locking design
• interchangeable with standard 3-pin neutrik XLR

Can you tell us more about the measured frequency responses?  What set up are you using?

Our setup is entirely proprietary. We utilize a piece of software developed by Justin and myself called "EquiLog".
You can find out more about it here:

Wow...that is all.

Hello

I have never built a mic before. Please excuse me on 2 levels. My lack of knowledge on the subject, and my not skimming through all 35 pages in this thread.

If I wanted to build an EQ47, Where I could I get the body, power supply kit, mic PCB and all other parts needed?

The EQU47 is a DIY friendly mic enclosure inspired by the Neumann U47 (including the same layered mesh pattern and internal headbasket dimensions).

You can build any mic inside the EQU47 you like; tube, solid state, etc.  There are several mic projects on this forum as well as other spots around the web.

As for where to purchase the EQU47, it will be available starting this Friday at www.equinoxsystems.net, but expect them to potentially sell out quickly; there are people who have been waiting 6+ months for these to be in stock.

If you'd like to receive additional updates about product availability, we have a mailing list you can sign up for here:

Progress.

B-stock will be sold at TBA price reductions as available.

very interested in b-stock bodies, as i've been considering a refinish anyhow.  if i went for a pair of the JV-team bodies, should i expect fit issues or are the defects mostly cosmetic?  sorry if it's a minor sidetrack or too soon to inquire, but it'll definitely affect my plans for friday morning  ;D.  well done gents.

Perhaps you could design a new bottom piece that has provision for a bolt-on Binder type connector, such as you're using now, or optionally a Switchcraft XLR (such as http://www.mouser.com/Search/Refine.aspx?Keyword=502-b3m ).  That way, if people want a tube mic they can go the Binder route, or opt, in the case of a FET circuit, to use the Switchcraft XLR.

Or you can design two different bottom plates, one for the Binder, and the other with an XLR-size tube that accepts standard Switchcraft or Neutrik XLR-M inserts.  Then people could select from a number of XLR insert options, including 7-pin for a tube mic, yet have the convenience of an XLR rather than a screw-on type like the Binder.

I would opt for the XLR version myself, as I want to build a pair of FET circuits in these.  As it is, I'll just make a short cable to adapt from the Binder to a standard 3-pin XLR.

There are a variety of issues in the B-stock inventory, i'll go over a few:

• small defects (milky spots or small dust particles) in headbasket nickel plating
• small dents/depressions in headbasket wire mesh which can usually be pressed back out
• small scratches or nicks on headbasket, body tube, or end cap
• outer mesh not biased at 45 degrees  (biased correctly on sides, just not top)

We have been very picky and very carefully QA'd every single unit in this batch.  It is very likely some people might not even be able to look at a B stock unit and figure out why it is B stock, but there is a reason.  Due to time and technical web store constraints, we will not be able to offer a method which tells you what defect your B stock unit would have before you order it; if you order B stock, you could get any of the above or possibly some other small defect not discovered yet.  All b stock units will be 100% usable; if a a unit has a significant non cosmetic problem it is parted out and the defective portion is not sold at all.

Whatever the solution ends up being, I will make sure it's simple and elegant.
I agree that there should be a straight-forward way to build either a tube or solid-state mic by configuring the connector.
Thanks for getting the wheels spinning—I'll see what I can do.

Hi Skylar,

I would like to support the idea that the Tuchel bottom bell is still an available option in the future.

As you have the design and the tooling already done, would it be too difficult to do another run of those as well, as an alternative to the XLR bell, so that future customers could state their preference when ordering?

If I was able to I would be ordering my bodies now, but like many others I'm cleaned out after paying my quarterly bills. I imagine I am not the only one in this situation who is hoping to buy an EQU47 in round three but with the Tuchel connector type.

What say you on the option plan? Isn't the Tuchel connector one of the touches that is a part of what makes the EQU47 so special, after all?

Right now, the end connector is Binder 691-series. These work great, but they're very expensive for everyone to buy.
My ideal is to revise the end cap for batch #3 so that it works with either an amphenol/tuchel 7-pin or a standard XLR 3-pin.
All the user needs to do is decide whether they want to build a tube mic or solid-state, and it would be a simple matter of dropping in the appropriate connector insert (available inexpensively at Mouser or similar).
I feel this would give added flexibility and be much more affordable to DIY builders.

This route would retain the "look" that makes the EQU47 special.

Can you be more specific? Which amphenol/tuchel connector type do you have in mind?

I was thinking 97 series in black, but honestly I've thought about Hirose, SealCon, and other brands with equally rugged and bulky circular connectors.
There's still a lot of sampling, testing, and measuring to be done. Still in the exploration stage.
