Default omni mics in live sound reinforcement

has anybody done this?

It seems like it would be perilous. just wondering if there is ever a
situation where it's useful. maybe placed in the middle of a violin/
viola/cello trio in a low-volume setting.

I tried it on fiddle one time. Not good at all. It sounded fine, but
had no gain before feedback to speak of.

We went with a pickup into a buffer.

Lots of people.

Tons of Countryman E6s are being used for live sound, and the basic element
is a subminiature omni.


One nice thing about omnis, no proximity effect.

Well, a couple of examples in addition to theatre work and lavalieres in
general ; the Shure 520DX, a commonly used harmonic mic is an omni.
Admittedly this could be argued about but Shure claims its an omni.

In bluegrass it is common for the group on stage to half circle around an
omni.

Sometimes an omni can be used without feedback in a band situation when
micing a loud instrument such as a guitar amp, however you will probably
pickup much stage "wash" as well.

It depends on the situation. You have the inverse square law working in
your favor. If the omni mic is an inch above the sound board on a violin
and the monitors aren't too loud (or don't exist at all, or are not
speakers, but earphones) then an omni can work very well. In fact there
are many tiny omni mics used in this manner all the time in sound
reinforcement.

As long as the mic is really close to the sound source, fine, but if
it's a quiet instrument and you have to crank the gain to make it
heard (like say an oboe), potentially big trouble.

Okay.... deep breath here.... think about the 1-3 rule. Now, imagine
with an omni microphone that the 1-3 rule has turned into a 1-10 rule.

So, it's fine, as long as you get it close enough. And it's fine when
you don't need a lot of gain, or when you can block the microphone in
such a way that the splatter from the mains is reduced.

One good example is back-miking guitar cabinets... a 635A can be great
there. The microphone is shielded from the mains and monitors by the
cabinet. The source is loud, the microphone is right up against the
source. GBF quickly becomes a non-issue.

It really is an omni. Shure used to call it a noise-cancelling mike,
but it's really not.

In bluegrass it is common for the group on stage to half circle around an
omni.


Actually, it is much more common to see a cardioid or even a hypercardioid
used here, because the gain before feedback is much better. I see the
AT4033 as one of the more popular mikes that bluegrass guys use for this.

Sometimes an omni can be used without feedback in a band situation when
micing a loud instrument such as a guitar amp, however you will probably
pickup much stage "wash" as well.


Yup!
