Everything I know about mics so far.

Octava hypers can do amazing things when in close proximity. While shooting a no budget movie for my church, I has scheduled a scene to be shot at a pizza restaurant at 2pm - just to be sure it would not be busy. Got our actors seated at a table, ready to shoot, when a ball team walked in. The place was soon jam packed and noise level to the point you had to shout for the person beside you to hear. We could not reschedule, so I
dropped the Octava just above head level pointing down and framed the actors soap opera style, extreme closeups. The background noise was there, but at the level I would have ended up replacing it with in post had there been no customers. The dialog was crystal clear and the mic certainly passed the test.

If you're indoors in a situation where you can, always avoid wind protection!

Not true, I'm afraid, especially with shotguns.

True, you don't need a full basket windshield with Windjammer - but you *do* still need a foam windshield as you will get wind noise as you move the mic.



(Oops - just noticed that this is a very old thread that I have just come across and have replied to a very old post - sorry - still true, though).

I'm curious. What is a hyper?
Click to expand...

A "hyper" is a Hyper-cardioid mic..

The pattern is about half way between a cardioid and fig-8 - it's about one part omni and two parts fig-8 (cardioid is equal parts of omni and fig-8).

The hyper-cardioid microphone has it’s angle of maximum rejection at 109.5º.
It is optimised for the maximum directivity coefficient of 4.0.
Rejection at 90º is -12dB
Rejection at 180º is -6dB

Super-Cardioid
The super-cardioid microphone has it’s angle of maximum rejection at 125.3º.
It is optimised for the maximum front to rear index and has a directivity coefficient of 3.73.
Rejection at 90º is -8.7dB
Rejection at 180º is -11.6dB

Though Sennheiser started the tradition of making a super-cardioid that has a directivity coefficient of 3.86.
Rejection at 90º is -9.5dB
Rejection at 180º is also -9.5dB
The attenuation at 90º is equal to the attenuation at 180º (the 180º signal being out-of-phase of course), this means that the attention is concentrated on the sound coming to the front of the
microphone.

The disadvantage of the hyper-cardioid is that sounds from the rear can be too high due to the lack of rear attenuation, and the disadvantage of the standard super-cardioid is that its side rejection is not enough.

I hope this helps.

So if I was a one man crew for a wedding and i had a boom mic for secondary sound and a Lavalier mic to wire the Groom....would the Oktava mk012 Indoor Mic do good for the camera mounted mic and a Lecto M150 for the wireless mic. Will this do the job for an alright sound for 1 man crew? Plus i need the best bang for the buck. If someone can fill me in on this that would be great
Thanks

The Oktava camera mounted would be a nightmare of handling noise. You can listen to my handling noise tests here. http://www.kenstone.net/fcp_homepage/right_mic_brockett.html
The Audio-Technica AT875r was created as an camera mounted mic and sounds great on camera, and off with a boom. I used it camera mounted for ambient on the Prison Break set last week and it worked really well.

Just a short note ...it is Dec. 2011...almost 2012....and I have really really enjoyed this thread.... thanks to all for posting !
