Topic: AT933 distortion

[j.mart]

hehe, this is getting pretty confusing..
these were (and still are) my thoughts about the cmc-8s

old versions of the cmc-8's, aka at933's: small body + adapter + at853c caps

new version of the cmc-8s, aka at943's: small body + small at943c caps

I have to disagree. Here are pictures from each model from the AT site:

853: http://www.audio-technica.com/cms/resource_library/product_images/c61598d80f344d03/orig/at853a.jpg
933: http://www.audio-technica.com/cms/resource_library/product_images/b2dfae1d1a225f9d/orig/es933c.jpg
943: http://www.audio-technica.com/cms/resource_library/product_images/37d9bd4b4d234441/orig/es943c.jpg

let's forget the SP (sound pro's 4,8) products, and focus on AT itself. The 933/943 difference is very hard to tell, and they are identical in specs, which leads me to think that they are the same capsules, only with different bodies. The adapter has nothing to do with the model. Altough, the 853/943 difference is quite obvious. Hope this clears everything up

ftr, the 933 is a discontinued model. so, to sum up, the 943 is a replacement model of the 933

you're probably right.. but still, my mics aren't in the pictures you linked to

i know i have sp-cmc-8's, i know my mics use the at853c caps attached to a smaller body than regular at853's through an adapter. here's a pic (that should actually be the first link in my previous post):

i thought they were the at933's, but that's just what i read in other topics..

My guess is that the SP used to furnish people that model insted of 933/943. only recently they started to display the name of the AT cap on their product, but you should contact them to be sure. I don't know why, but i'm pretty sure on what is what when it comes to AT caps.

I think we're getting there in unravelling the mystery of the small bodied mics!

If you examine the two spec sheets for the ES933 and ES943 bodies:

Hanging, ES933:

Lavalier, ES943:
http://www.audio-technica.com/cms/wired_mics/4ea31b4441f095b9/index.html

The specs are identical EXCEPT that the ES943 has a groove for the clip.

I believe that Stutter is right, Sound Professionals used to supply (as model SP-CMC8):

ES933 body + adapter + AT853 caps

This is what I bought originally as a 1998 model (they are now lost), and I believe is what SkttrWave has.
 
To use them as lavalier mics (ie with clips), they had a clear plastic ring and these clips (I still have a couple, thay are useless to me without the ring):



When the AT943 caps came out, SP used these instead, at the same time changing to the new ES943 body, with clip groove.

They kept the same part number, SP-CMC8 to confuse us..hehe

Humbug

ps SkttrWave, how are you getting on with sourcing a 3-wire bb?

There are many variants of these mics.  I should know, I've got (too) many of them!!!

All bodies (including AT831 BTW) are similar.  The two caps are either big (AT853) or smaller (AT943, ES933).  The bigger caps sound (a bit) better.  All of them need the 3-wire mod to sound decent.  Even under somewhat loud environments (ie., any rock show) you should see an improvement with proper powering.  Use either Phantom adapters or 3-wire and they will sound great.

I have been using the 4.7k mod with the 2-wire for some time now and have had terrific results.  I have taped in very loud rock situations with no distortion.  It is nice having the 2-wire because in times when you need to be very stealthy you can just plug the mics directly into you recorder.

Yep, that works great too.  I've found loud sounds will overload if you just run plug-in-power.  But great for stealthing quieter shows.  But most of my mics have a hard-wired battery box anyway.  Not much more to carry and no worries about levels.

it's getting a lot clearer now
only thing i'm still not sure about: is "at933's" the proper way to list my mics in source info?

ps SkttrWave, how are you getting on with sourcing a 3-wire bb?

I don't have the parts yet. I do know what i'm going to order and hope to have everything before the holidays, then i'll have some free time to start working on it.

According to the info given above, you should have the 853 capsules. They are the big ones right?

If so something like this should do it: AT933 (AT853 caps), or simply AT853. I'd go for the latter.
