I ordered a calibrated mic. Do I need a microphone preamp to power it in order to use REW? Any suggestions to which one if it is needed?
Thanks!

You'll need something to provide phantom power for the microphone. I'll let others give pre-amp/soundcard recommendations, but I'm partial to the Presonus firewire line of sound cards.

Re: CSL-Calibrated EMM-6 microphone sale

I'd be willing to bet they're the same microphone as the Behringers made in the same factory by the same people, just sorted & labeled differently.

I was VERY unhappy with the Behringers. They would probably be OK just for measurement purposes, but Behringer way too noisy for anything else. They publish 3 different sets of specs for the same microphones and I don't know which ones to believe. Though the specs INSIDE the box seem to be close.

Strangely, almost all pencil omnis use the exact same Panasonic capsules including some of the Earthworks mics. The main difference is #1, how the capsules are preselected/sorted and #2, the internal electronics. After my dissapointment with the Behringers, I returned them and got a set of Avenson STO-2s which come as a matched pair in a nice little wood case. They're cleaner and quieter which is great for me since I do recording work.
Well yes I have to agree it’s a name change of short. Tell me, this isn’t the same microphone as my ECM8000.



Even the microphone supplied with JBL LSR series looks the same

Although there is some slight cosmetic difference with the JBL calibration microphone!



Even dbx have their own calibration microphone. hold on I’ll get the spray paint out and spray mine black!:bigsmile:



The parts that make up the microphone itself are cheap right? I think there no more than £5.00 pounds! Might as well buy the parts and stick them on penile with blutac.:rofl2:

If loudspeaker measurements are your primary use (as opposed to room acoustics), you should be okay with the basic model.

Guess I didn't ask the ? properly. I'm not really interested in measuring just the speakers. My goal is to work on room acoustics, but full range, not just for the future subwoofer. Only mentioned the Khorns because I believe their dispersion (being corner horns) may be different than the typical direct radiator speakers.

Thanks for your good support with this.

Sorry for quoting myself here, but perhaps Anechoic missed this. I would like to order a mic, and know the sale ends soon. Which one should I order considering the above?

Thanks very much,
Rod

Well boys and girls, the sale is over.

This is what I'm left to deal with:


(this is shipment #1 of 6)

So I'm going to be pretty busy in the lab trying to process all these mics. First batch went out already and the next batch should go out later today.

I'll try to pop back in later with some observations by my initial impression is that the ECM8000 is a batter mic below 20 Hz and the EMM-6 is a better mic above 20 Hz.

The good news for those that missed the sale is that when I'm done filling all the orders I should have some extras that I'll sell for the discounted rate. I'm not going to offer the $5 off for HTS members, but I will post here first to give HTS members a shot at it. Those extras probably won't go on sale until the 2nd week of October, but since I'll already have them, they should ship quickly.

Thanks a lot guys for giving me my own little stimulus program. ;)

Newbie here. I have the Radio Shack 33-2050 meter for measurement. I understand it is very low resolution compared to this EMM-6. Now if I was to buy this, can I also use this for other uses (like a regular vocal microphone for karaoke)? It's not a lot of money, but if I just to cal my sub I think the RS meter is fine, right? Thanks!

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.

Interesting question indeed.

It's an open-loop voltage measurement.

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

Anechoic,

I'm in absolutely no hurry for mine as I don't have the other equipment I need to use it and wont for awhile. So feel free to take your time with mine.

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.

Don't sweat it, I was away for the weekend and now that I'm back I just wanted to give a status update. You good people have given me your money and you all have every right to know when you should expect to get what you paid for.

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.
