Powering SP at933s

(1/1)

John Kelly:
Right now I'm running a modified AD-20 which powers my at933s with battery power.  However, I'm very tempted to get a new preamp, and I'm looking at the M-Audio Firewire 410.  The thing is, that pre only provides phantom power (like most other preamps out there) and I don't have a battery box.  

I've seen this discussion before, but I never found a solid answer.  Can the SP models of the at933s be powered by 48v phantom power?  Has anyone actually *tried* it?  

blu666z:
I have never tried it myself but I don't think they can take 48v.  My AT ES943s take 9v.  I'm thinking 48v wuold fry their asses.

John Kelly:
See I've heard the opposite (and that phantom power and battery power are pretty different), but I was wondering if anyone had tried it...

nickgregory:
I have heard folks have hooked up their 853 based SP mics to 48v phantom and they here the mics crackle...definitely not a good sign...I believe I heard in the past that someone asked Chris at Sound Pros and he said that they were not wired to accept anything higher than 9 volts...

yes you can, but you'll need the AT Phantom Power adaptors.  the model # is AT8533 9-52V Phantom Power Module.
