Re: Mic question

[Mark Finley]

I should add that it only has to be used to pick up the spoken word, not
singing. If that makes any difference.

What's it for? Singing? Public address? What enironment? A living room?
An auditorium? The police station? Indoors or outdoors?

In short, what other factors attend the intended use of this mic?

It's for a baptismal at church. I would like to suspend a mic above the
pastor that will pick up his talking. Right now we put a dynamic mic in a
mic holder that is about at mouth level, but a couple feet away from where
he is actually standing. We have a hard time getting the gain turned up
enough to hear him without feedback.

The Audio Technica-AT853 is a very popular and effective mic for this
application. There's different versions, depending on your needs...AT853a,
if your mixer doesn't have phantom power capabilites. AT853Rx if it does.
They come in black or white...

Mark if you going to go with a "regular mic' go with a "starndard, ie a
sm57 process it with a parametric eq of Sabine FBX solo and a compressor
the reason for the sm57 is condensor mics HATE humid enviroments
a beta 57 would be a better choice

you could mount a goosneck near the point of use or possibly a boom stand
the AT mic would need to be so moveable that the hanging option is really
unusable
and if they are not close the feedback gremlin will get you
these are great for choirs but not so great for single spoken word

you get into the entire"how do I prevent feedback " issue with this
situation

the best way to prevent feedback is to get the mic close to the preacher
fortunatly I have never met a baptist preacher who did not deliver his voice
powerfully enough to be heard

if you around Central NY I would be glad to come out NO charge and demo some
systems

IMO the order of systems I would choose would be
1 wireless lav
2 gooseneck/stand dynamic ala beta 57a
3 Boundry effect (shure beta 91a mounted on wall across from preacher(but
within 3 feet) water sheilded
4 Hanging choir type mic

I would have a parametric eq(or sabine unit) inserted into this dedicated
mic channel for any mic

this baptismal mic should not be a general use mic that need to pull duty at
the organ or choir, it should be dedicated for baptismal only as the eq
curve required to get good results is extreme and not compatible with
"outside the tank" applications

I was reading George Gleason's comments, and one thing he said that seemed
to make a lot of sense was to use a SM57 (or 58 I might add) because
dynamics live better in moist environments. Well, there's lots of dynamics
and the EV 635 family is almost as popular as the SM57/58 in some markets...

I think that the dynamic/condenser issue partially depends on how many
baptisms you have. Some churches have them every week (and that's a good
thing!) so moisture resistance can be an issue. Other churches have them
once a year or less (and that's not good, but it can be real-world) and it
probably doesn't matter what kind of mic you use from the standpoint of
moisture.

We use a SM57 on a nasty old chrome gooseneck with a big foam pop filter in
our baptistery. We don't have a lot of baptisms and the same mic is used by
guest singers most of the rest of the time which is to say it's hardly used.

The downside is that SM57s and most dynamics aren't what you'd call high
output mics so you're probably going to have to goose the console trim to
get good levels.

So use a SM57 and goose the trim. Now, the only remaining question is what
your feedback margins look like. You said they suck in your room.

In our case we have really big JBL constant directivity horns set up in a
well designed-pattern. The baptistery is at the back edge of the platform.
Therefore, on the stage and especially in the baptistery you almost can't
tell if the SR system is on or off by just listening for the mains.

IOW, feedback from the mains just isn't a problem in my church. We've got an
8-bus mixer and the baptistery mic doesn't come within a million miles of
feeding the stage monitors. Stability city as long as the knobs are set
right.

You might want to look at the acoustical reasons why your stability margins
are so poor. Is it because your mains are not set up right? Is it because
you're putting the baptistery mic into the mix for the stage monitors? Is
there an acoustical situation in and around your baptistery that a few
sheets of 703 or foam could address?

One recommendation that I'm prone to disagree with would be to use a
conventional wireless system with a lavalier microphone. IME its hard to get
a lavalier to sound right, but that might partially because I'm aware of the
lousy physics of the situation. I think George tacitly commented on this
problem when he recommended using a good non-trivial equalizer. I should do
that for my main wireless system as Mackie mixer equalizers are pretty bare
bones.

If the pastor trips in the baptistery, you're out one non-cheap wireless
system.

Some kind of modern right-at-the-lips mic might sound like an attractive
solution.

However, its a really nice touch if the SR system picks up the words of the
person being baptized, who is often a much less optimal speaker than the
pastor (George's comments on Baptist minister voices being IME right on),
and even further away from the mic than the pastor. If you run with this
problem a while, you might even want to use an omni. I think George might
have tacitly commented on this problem when he mentioned the compressor. I
should try one, it might even make a believer out of me.

From a ministry standpoint I'd like the congregation to get the idea that a
baptism is two-way thing, and I see some priority to giving a good represent
ation of the testimony of both the pastor and the person being baptized. I
don't dig compressors but I may have to broaden my thinking.

However, I might just try an omni (Behr ECM-8000) next time I have a baptism
to do. It would kinda kick up the trim for me automatically because its got
lots of gain over a SM-57 on its own.

People tend to turn green when one mentions omnis and SR in the same
sentence. However, they can be problem solvers for SR. For example, what if
your stability problems trace to reflections off the back wall of the
baptistery that your existing cardiod ends up focusing on very tightly. An
omni could help that problem with a broader pattern that averages the sound
from a wider area. Because the talkers are relatively close and the
baptistery is filled with near reflections of their voices, their voices
might still have precedence.

YMMV and FWIW...

[George Gleason]

Many good points Arny

For PA or recording?
Are you looking for a podium mike with a tight pattern?

In general, any mike with a tight pattern will do this, but for PA work
you also need to spend some time making sure the speaker system isn't
leaking into the mike, and with either recording or PA you need to get
the room fairly dry.

1. Try an AKG C747. It sounds like a telephone, but you get one hell of
a tight pattern at a short distance.

2. Move your speaker system so the speakers are in the null of the mike,
or as close as possible to it.

3. Use aggressive notch filtering (either with a Sabine box or with a
simple parametric EQ) to remove the dominant feedback modes.

You've seen the other answers, My choice for this would be a really good
supercardioid such as the SchoepscMC6/41, but since that is really out of
budget, my second choice would be an Oktava with the hypercardioid capsule with
careful placement.

Really small mics (AT853) don't have really tight polar response, and tend to
have high self noise.

Good point - I think I have some nifty 3M sealing putty that would do the

double-bagging?

Actually, how about the EV N/D 408 or 468? Still a dynamic, but a much
tighter pattern than you get from an SM57.

BTW, Staples now carries a 3M high-strength double-sided grey foam tape that

version which is mediocre, so don't get the wrong stuff. This stuff is
GREAT! They also have an "Industrial Strength" self-adhesive Velcro that is

everybody!

Maybe I'm using some confusing terms, as I am a bass player who recently had
the A/V job thrust upon me, and I am trying to correct things that I know
are substandard.
By feedback, I mean if we turn up the gain so much that the voice can
actually be heard in the baptismal chaimber, the sound sounds too distand,
and we are very close to have the "squeal" come through. I will try turning
down the monitors next time, but we just don't have enough signal coming
through to even light any lights on the mixing board.
Scott in answer to your question, mainly we need this for PA, but it
wouldn't hurt to also be able to feed the signal into our recorder. (MD

Thanks for your help and not making a newbie feel stupid.

Good for you. And you've got your "feedback" rightly termed.

This raises questions in my mind about appropriate gain staging
throughout the signal chain. First get the mic signal into and throught
the board with proper lighting <grin> so that you're operating more
optimally there, then downstream adjust the amps or if you have them,
equalizers and/or crossovers. For instance, by turning down the amps,
you can turn up the console master output and put the board into a
better signal-to-noise arena.

Get the pastor's voice out of the monitors. How large is the chamber? Is
a mic to hear him live really needed? If one just needs to record the
event, then route the mic to storage and skip the PA.

In short, you're going to need to get the mic close to the pastor.
Placed at a distance in a very live room any micing system will appear
prone to feedback. Using a shotgun to narrow the field of capture means
the pastor's movements may put him alternately on and off axis to the
mic, with wildly varying levels from the mic.

This might be a situation where, once the gain staging is optimized and
an appropriate mic and technique chosen, one of those automatic feedback
busters from Sabine, Behringer, etc., could help.

You newbies don't know nothin' about stupid. Real stupidity takes
longterm professional experience. Trust me.

One more thing: you have brought this treatment upon yourself with the
manner in which you have responded to reqeusts for additional

The "distant" sound could be due to echoes in the baptismal chamber (likely
tile - just like the old-time trick of using a bathroom as an echo chamber),
or it could be due to pickup from the monitors and/or the main room. Or
both.

Please see former comments about Owens Corning 703 sound absorbing
insulation or acoustical foam panels in the Baptistery. Absorbing sound
works best if you alternate reflective and absorptive areas. In most
Baptisteries you should be able to put the absorptive panels mostly out of
the line of sight.

> I will try turning down the monitors next time,

You should be able to do that for just that one channel, thus not hurting
operations in the rest of the room.

What mixing board?

I wouldn't get overly worried about not flashing the light. However, please
see former comments about turning up the trim for that particular channel on
the mixing board.

This is caused because sound from the speakers is leaking into the mikes
and being regenerated out again. Your job is to minimize the amount of
stuff making it from the speakers to the mikes.

This gets to the mikes either directly, or after reflecting off of surfaces.

Radical equalization can help, but only after you have done everything else.

Can you hear it, though? Doesn't matter what the meters do as long as it
sounds good.

>Thanks for your help and not making a newbie feel stupid.

I think the FAQ has a pretty good discussion on feedback and how it happens
and what to do about it.

I guess what I don't understand id how feedback can happen if there is hardly
any sound coming through ANY of the speakers, including both the mains or the
monitors. and they are 20 feet away from the baptismal booth. maybe is has
something to do with the aucoustic environment iside the booth, which is like a
bathroom.

He didn't say where to clip it. It could be clipped to his collar, or
glasses frames, or whatever they wear to a baptism. It's only the one
being baptised that goes all the way under.

Actually, AKG showed a minature mic a couple of years ago that they
had water flowing across (and it was still working). It was designed
to be sweat-proof for those active theater people.

We use a Crown PCC on the floor (baptismal(sp?) top is stage level) in
front of the baptismal. Decent gain before feedback. Works fairly well.

Yes, and if I'm now getting the picture, the dunking happens inside a
booth inside a larger chamber? And both of them are probably pretty
resonant spaces with a lot of ambient sound hanging around?

Narrow-band resonances in such spaces can help destabilize a sound
reinforcement system even at very low levels, where the system itself
isn't even delivering "useful" sound.

If the total gain around the system (including the speakers, the mics,
the amplfiers, and the air) is greater than unity and you don't have
much phase shift, you have the potential for feedback. All it takes to
get feedback started is just a single noise - a pin drop will do it.
Once it starts, you no longer have hardly any sound, you have a lot of
sound, so it's able to sustain itself until you reduce the gain in
some way - turn a knob or move a microphone or speaker.

At which point I'd look towards a headset or earset mic, least
noticeable example being the Countryman E6
http://www.countryman.com/html_data_sheets/e6data.html

Otherwise, I think Scott's suggestion of the AKG C747 is your best bet.

The issues are: how near the speakers it is, and its pickup angle. If it
has a very narrow pickup angle, or maybe even a shotgun, it will reject
more noise from the sides and be less prone to feedback through picking
up sound from the speakers.
