The 296 was asked for by Gotham Audio in NYC. It was to be an M50 imitator because it too had increased directivity at higher frequencies. The above was told to me by Jerry Graham at Gotham. |

I enclosed a file with a recording I made in 1994 using the 4045 as a test. As soon as the soprano goes up to the higher octaves and gets loud, I hear a pressure on my eardrums, I do not know if MP3 is good enough to show you that. This recording was made with a small A-B of two 4045's. http://webzoom.freewebs.com/eriksikkema/Soprano.mp3 |

I have constructed a very simply diecast box with XLR ins/outs and inside I parallel 5 X Duracell 9V batteries which actually give me 48.5V, and llast for at least 5-8 concerts before needing replacement or the addition of another battery. |

The sound improvement is HUGE. Same works wonders for other mics. |

There can be a negative side when using measuring microphones. The resonance point of this microphone is around 11Khz, there is a 90 degrees phaseshift already around that frequency, which gives some unpredictable behaviour above 20Khz. |

Hello Kostas,
Could you please describe that a bit? What is the difference in sound and in which way is it improved by battery powering? Best regards, Markus |

I found the samples here, origional directed to them by another person. http://www.mil-media.com/LargeEnsembleListeningTest.html There are some more for comparison that may be of interest. Erik, I like your sample, thanks for posting it. To my ear it has some depth to it, how big was the hall ? Dave Blackham UK |

What is the B&K (DPA) 1/2 capsule equivilent of the 4145, ie a B&K mk221 that would be suitable for music recording. If mated to a Josephson would it be prefered over a 4006. thanks, Dave Blackham UK |

Quote <I am still concerned with their S/N for some applications > Do you think it is the preamp or the capsule that is noisy ? Dave Blackham UK |

But, the B&K and Gefell have a much lower (not specified) lower mechanical harmonic distortion. |
