Bought an AT3035 on Monday. Finally got a chance to use it last night.
Plugged it in, turned on the preamp, flipped the phantom power switch. No
sound. Nothing. Not a sausage.

Checked my signal chain. All was right. Turned off the P-power and the
preamp and switched it with another mic. Worked fine. I'm assuming it's a
bad mic. Is there any idiosyncracy with the 3035 that might have caused this
(don't want to drive all the way back just to find out the mic's okay and I
effed up), or did I just get a bad mic?

Did you switch the mic with another condenser? If yes, than it is most
likely something wrong with your AT3035. If you tried with a dynamic it
could be something wrong with your phantom-power.

Yes, it was another condenser mic.

Take 'er back. It's messed up.

Hmmm does the 3035 require a full 48VDC Phantom.....?

Why yes it requires 48VDC and 3ma of current to be happy. Was your phantom
supply capable of that? Some aren't

Which preamp?

Jeeze Ty, it would be a pretty sad preamp that could trickle out a measely
3mA, wouldn't it ?

David Satz has pretty much put the fear into me about various
contemporary commercial phantom supplies.

Trust, but verify. (Politics!)

Geoff,

Why yes it would, but there are some out there I've heard about that don't
deliver it, or mixers that can't deliver it for more than a couple of mics
before starving the rest.

Somewhere there are Phantom Supplies that give 24VDC and that's about it.

If he was using electret condensers, he might be fine because they take less
juice.

Dunno. Just a few thoughts.

Ty Ford

Example, Rolls MP-13

Even less voltage:

Example, a Behringer MXB 1002 running on batteries.

Example: A number of the Benchmark Media mic preamps only put out 12 volts.

Moral of the story - sometimes its nice to have a stand-alone phantom power
box. Mine is A/T's 4 slot box.

Other moral of story, there are some mics that have problems if you go even
slightly over 48 volts. Mogami sent out a whole slug of MXL-603s that got
very noisy this way. They'd fix them for free, but it was inconvenient if
you had any of them.

It would, but it's not unheard of for a preamp to trickle out only a
measly 18 or 24 or 30 volts open circuit. Nor is it unheard of for a
mixer which provides 48 volts open circuit to drop to a too-low a
voltage when more mics than the designer counted on (but still fewer
than the number of inputs) are plugged in.

I was using a dbx 286A preamp. According to the manual, it's 48VDC (doesn't
tell me the amps).

Benchmark is a well repected company. I've heard only good things about these
preamps from people who own them. Is the 12 volt supply an oversight or is
there a good reason for it?

Actually the IEC specification that defines phantom power has criteria
for 12, 24, and 48 powering. I'm sure that Benchmark isn't trying to
put one over on their customers, it was designed for use with
microphones that work with 12V. The AKG C451 works fine when powered
with a 9V battery.

Don

(I'm the original poster) Well, the mic wasn't bad, I was a dumbass,
apparently.

Took the mic back to Guitar Center, the guy pulled another one, and just
before I left, I asked him, "do you have something you can plug this in and
test, just in case." So he grabbed the new mic AND the old one I'd just
returned. He plugged them both in and they both worked.

I assumed I must've had something unplugged or something. I get home, plug
it in and nothing. Still doesn't work.

Then I realize I was running the mic cable into a patch bay and back out to
the preamp. I bypassd the patch bay and the mic works fine. I guess when the
phantom power went through the patch bay it lost some mojo and couldn't
power the mic.

Should I take this to mean I'm not supposed to route phantom power through a
patch bay at all? Or just not with this mic?

Does ANY mic get proper phantom power through your patch bay?
If your patch bay properly passes all three conductors (tip, sleeve,
ring) through properly, no reason why the mic shouldn't be getting
power.

This is correct.. but you shouldn't route phantom power through a 1/4"
patch bay, because of the unpleasantness that happens when the cable is
plugged in. If you need to route mike lines, use an XLR bay.

Yup. I own three other condenser mics. All three of them worked fine routing
through the patch bay. But I'm not going to route mics through there anymore
anyway.

Running mics through patchbays, in general, is a bad idea unless you have the

entire patchbay enclosed in a metal shield, all audio is balanced, and there
are no other audio lines (-10 or full line level) running in that patchbay.

Even then, I'd probably never do it.

Ty Ford


Just the thought of it makes me nervous. The extra connections alone are
enough to scare me off.

Some old Peaveys, for example, as well as a few others that have deservedly
become extinct, such as Tangent. I think some of the Rolls portable mixers
provide only 12 volts of phantom. Fine for a C451, recipe for disaster with any
Neumann.


Scott Fraser

seems like i ran into an old (early '80's?) shure mixer (pa "console"
type, not a small mic mixer that you see so many of) that had 24v
"T-power" or somesuch. it wasn't in my life long.

Shure never used T power (unless it was on one of their field
production mixers) but they did use 24V phantom power on the SR-101
and ProMaster mixers. Since their SM-81 mic works fine on 24V, they
figured that was all anyone needed.
