I apologize if starting Yet Another Dayton EMM-6 thread seems excessive but since this is time sensitive, I wanted to make sure I got your attention.

Parts-Express is having a sale on EMM-6 microphones: $39 + shipping!

Being the magnanimous guy I am, I figured I'd calibrate a few EMM-6 mics and pass the savings on to you!

CSL-calibrated EMM-6 microphones, starting at $70 + shipping.

Of course that pricing is for the little people. Home Theater Shack members are special people (special in a good way of course :) ).

Any Home Theater Shack member who has an account as of September 17 gets $5 off. Just include your HTS username in the "additional information" section of the order form and I'll refund the $5.

The PE sale ends on Thursday, Sep 24. When it ends, so does my sale.

Hi Anechoic,

I ordered the Premium service the day this deal came out and I have a question about the sensitivity measurement. Is the sensitivity figure an open-loop voltage (load impedance >> source impedance) or a voltage delivered to a preamp input impedance which may be low enough to make a difference?

EMM-6 source impedance is quoted as 200 ohms. My microphone preamp (EMU 0404 USB) has an input impedance of 1500 ohms. The voltage at the preamp would then be 1500/1700 = 0.882... times the open-loop voltage or approximately -1 dB.

Very interesting question, I would like to use the same preamp as well.

Hi everyone,

I've been getting a bunch of messages essentially asking "where's my microphone"?

Since you've given me your hard-earned money, that is a completely reasonable question deserving of an answer.

I've shipped out ~35 mics so far. Up to this point I've been attempting to get mics out a few at a time every day on first-come, first-served order basis out of a sense of trying to be fair. I've come to realize that this was horribly inefficient so what I've been doing is processing mics in lots of 75 to try to get them out.

Orders placed before Sep 21, should go out by Weds (a few might dribble out on Thursday). I mentioned earlier in this thread and on the order page that orders placed after 9/21 won't ship until Oct 6. However, I might be able to get a few basic orders out before than.

Please be patient. If this isn't acceptable to anyone, you may of course have your order refunded. If you have a specific need, contact me directly and I'll see what I can do for you.

Thx

Update: about 2/3 of the orders have been shipped out. A few trickled out today, a few will trickle out tomorrow, and the bulk of the remainder should go out on Wednesday. Some people made special requests when making their orders - those orders will hopefully go out by the end of the week.

BTW, I will have extras. Stay tuned.

Just want to confirm that I want one of the extras. I will now look back on the postings on how to get this money out of my pocket and into yours. Too bad about the end of the 5.00 discount, but is more than worth it overall. And no rush for me, take care of the ones in dire need first.

Edit: done, but forgot to include my hts name.

I had hoped to wrap up all the orders by yesterday, but they didn't happen - all the mics are finished, but printing invoices, keeping track of orders and packing everything is taking forever. On the plus side, a few of you (accidentally) got free upgrades with your orders. Enjoy! ;)

As for everyone else - final order group will ship tomorrow.

Okay people, I just returned from the Post Office where I dropped off the last group. With one exception, everyone's mics should be on their way, or already delivered.

About those leftover mics - I wrote before that I would get around to selling those next week. I lied :)

I have seven mics left over. I'm selling them at the discounted price, but without the additional $5 discount for HTS members. However, I'm posting this here a couple of days before I post in other forums to give you guys a little head start.

There is a limit of two microphones per person. If you order more than two, I will cancel the order refund your money (and you'll lose you place in line).

Shipping: Mics will go out no later than Wed, Oct 14 and I should be able to get Basic and Basic Plus orders out before then.

Order here.

I do have a question about about how to take care of the mic.

Previously, on my ECM8000 mic, I'd leave it on the light stand with the cord attached so I'd have less stuff to put together whenever I got the urge to run REW.

I see that the EMM6 comes inside of a plastic bag with those drying crystals. Is that really necessary once the owner gets it if the mic is kept in an air conditioned space ?

As long as you're not actually using it in the rain, you should be fine treating it the same as your ECM8000. The bag and desiccant (I think) are just for shipping purposes.

Also, wrt to deals on ECM8000/EMM-6 or other similar mics - if any of you ever stumble upon a sale on that type (or really, any type) of microphone, please let me know and I'll be happy to do the same thing and buy a bunch of them and pass on the savings.

There are still the regularly-priced calibrated ECM8000 that I sell, although I am running behind right now. And as I wrote above, if you see a sale on ECM8000/EMM-6's or other mics, let me know and I'll be happy to cal them and pass along the savings.

I'm thinking about transitioning the line to EMM-6, but the biggest thing holding me back is that I can free next day shipping for ECM8000's while shipping for the EMM-6 is considerably more expensive if I want to get them next-day or 2-day delivery.

Ok, let's talk about what's in the box


All is top shape, very good packaging, safe and lightweight.

Regards
That's a fantastic picture. I may have to steal it :)

I should mention that about halfway through the production run I changed the labeling for the business-card CD's, and very late into the run I ran out of business-card CDrs so I started sending them out in mini-CDs and full size CDs to avoid further delays. Just in case someone is looking at their CD and wondering why it doesn't look the same.

(Euterpe, did you get a mic clip? I ask because I have an extra here so I know somoeone out there didn't get one, but I'm pretty sure I know the serial# of the mic the clip is from).

A few brief observations of the EMM-6s:

1. They are much more consistent unit-to-unit compared with the ECM8000 although there are still some outliers.

2. IMO the mic clip and the mic case are flimsier than the ones included in the ECM8000

3. I don't like that the box for the EMM-6 is slight larger than the mic case, which means the case can bounce around during shipping. When I sent out my mics, I put some bubble-wrap or wadded paper in the box to tighten things up.

4. The sensitivity values I measure for the EMM-6 are consistently 1 dB off from the value in the included sheet. As I wrote before, I have two acoustic calibrators that have been varied from two separate third-party NIST-traceable labs and they agree, so I think my values are correct.

5. I kept one EMM-6 for myself (well, actually I dropped it and put a dent in it and I figured it would be unfair to send it to a paying customer) so I'll do some distortion measurements and eventually get around to taking it apart.

Thanks for your reply Jim,
Hmmm... So what mixer/power supply do I need? Kinda looking for the most economical solution. I will be using this mic in conjunction with REW and would like to be able to measure the full frequency response of my subs and speakers.
What about the Behringer MX-400 4 channel line mixer? Would this work?
Sorry... I'm still new to all this.
Thanks again for your reply and hopefully you guys can point me in the right direction!
Darin
