hypercardioids and mv/pa
Hello,
I was looking at a mic spec for a hypercardioid mic (the Sterling Audio ST-31). It only has 5 mv/pa output. That seems too low. Do hypercardioids have less mv/pa? Because the company has similar products with much higher outputs (higher than 20mv/pa) when they are cardioids. I'm wondering what the disadvantage is to such a low output. If you are trying to capture sound from 10 feet away, it seems like you would want a mic with more output. |

Great preamps offer gobs of clean and quiet gain, which is necessary with insensitive mics. -- ha shut up and play your guitar |

No, you just turn the trim control up a little bit more. Gain is cheap. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Your issue(s) may be more about clarity than volume, sensitivity or gain. Later... Ron Capik -- |

This is like saying that blue cars are slower than red cars. In the same way that a car's colour has nothing to do with its top speed, so a microphone's pattern has nothing to do with its sensitivity. Some very highly acclaimed microphones have much lower output levels E.G. Electro Voice's RE20 (cardioid) mic has a stated sensitivity of 1.5mV/Pa. See http://www.electro-voice.com/documen...ta%20Sheet.pdf Because the company has similar products with much higher outputs (higher than 20mv/pa) when they are cardioids. Do all blue cars have the same top speed? I'm wondering what the disadvantage is to such a low output. None whatsoever. Just make sure you have a good quality pre-amp. If you are trying to capture sound from 10 feet away, it seems like you would want a mic with more output. Not at all. This is why a microphone is first connected to a pre-amp, so that no matter what the actual output level from the mic is, the pre-amp boosts it to level appropriate for your mixer.
