Topic: powering at943's

[jerryfreak]

what sort of power do they want? SP's site says they run on plug in-power, or can be used with the phantom power adapter. in the specs it say sit wants 48V phantom at 4ma per mic (thats a lot for mics this size), i'm assuming that means with the adapter. If powering these caps directly, what 'plug-in' voltage do they want? and what is the current draw at that voltage

best powering option for these is 9v 3 wire battery box. you can't put 48v phantom to these unless its with the adapter and down converted to 9v if i am not mistaken. i assume you are talking about the sound pro CMC-8 mics which is the AT943 small body cap.

there are a lot of threads discussing the powering of the AT943 and the AT853 and all conclude that the 3 wire BB is the best way to go since this is a 3 wire mic.

you can do the 4.7k mod to them which would let you run them with a 1/8" plug into a standard 2 wire box like SP sells. you can also run with phantom but you need the At8533 adapter or similar PM4 module which brings the power back to 9v. this is a 3 wire setup as well (XLR). the other 3 wire option is mini XLR and there are boxes to find in yardsale or i think chris church makes them.

i would search 3 wire bb on here and you'll find loads of threads.....

The preamp I sold you will work with these mics. But you really should send it back to me so we can get it to work with your Schoeps...

well, i'm actually trying to get it to work with a mic2496 for a fellow ts'er

while i dont expect you to support that product, if you know the voltage these caps want directly, and what the different color wires designate (white, red, ground), that would be helpful. I assume red=power, white = signal, or vice-versa? i know what voltages the mic2496 puts out when jumpered in different ways (although the mic2496 when jumpered down to 9V is actually 'bias' power on the same as the signal wire, so i'm guessing a 4.7K off of this common power/signal wire, connected to the power lead of the mic?)

i tried emailing len last week to no avail. anybody used at943 with a mic2496. Its got 48V phantom, but then the adapters are huge and its not very low-pro.

FYI, searching '3 wire battery box' or 3-wire battery box' only brings up this thread. any links to further reading?

3 wire powering is the way to be.

Use a pair of 10k resistors and a 9 volt battery with a 10uf poly cap and your set. You can run the mics two wire and they are all good to go let me know if you need any help.

thanks guys, I'll do some homework!

Not always lol....   

EDIT I guess I did not say enough in this post.. So I am going to add to it.. WE NEED MORE COWBELL....

i don't see any reason to be laughing at them. that just seems mean.

I see no problem laughing at phantom adapters or 3-wire setups !

I do get it:

I would rather run:
AT933s/4.7k-mod(H/O)>9v Bat Box>AD-20>NJB3

Than:
AT933s(H/O)> jklab modified Samson PM4s>ps2 >AD-20>NJB3


To each their own my freind!
