Have you had any problems with low frequency feedback ? The ECM8000 is the first Mic I've tried that when you connect it to a stereo in a normal room, will actually give feedback at low bass frequencies (like 35Hz etc) *before* it will give feedback in the midrange. I guess most hand held mic's designed for vocals (including one I was using previously) simply don't have the extended bass response necessary to trigger feedback at such low frequencies. I guess in a choir use you'd have the low frequencies from the mic rolled off a bit though ? Regards, Simon |

Electret capsules like the ECM-8000 uses, have no trouble achieving flat LF output, if the acoustic input levels are not extreme. Maybe it is time to re-test your mics??? |

They are a mic you can use with confidence in your application. I have
no doubt that the older mics are definately flat enough to do speaker work. Just get yourself a 1/2" calibrator on Ebay so you can establish an accurate reference level. I'll report when I chance upon a newer unit, but I doubt much has changed. -k (Simon Byrnand) wrote in message . com... (Ken Kantor) wrote in message . com... Hi Ken, Based on terminal measurements, none of my ECM-8000's appear to have transformers. To verify, I actually opened one up this evening. Needless to say, I messed it up, since the wiring is very tight inside. After I repaired it, I had to re-test its response. (I curse Usenet, again...) Sorry about that Ken... points finger at Arny  Compared to the reference mic (in this case a GenRad), it was within 1 dB down to 10 Hz, the limit of my test jig. I tested a second unit that was identical at the low end. Of course, the quality and input Z of the of the preamp will make a difference at the frequency extremes. Well thats really good to know. When Arny said they were 3dB down at 40Hz, I was a little bit concerned, but it sounds like this is not the case. I wonder if the IC version has a bit of active compensation to flaten out the low end ? (Assuming the capsule needs it...) I have to say, though, that I haven't bought one of these mics in a few years, and so I can't be sure the design hasn't changed. Next time I am in GC, I will pick one up. Yeah, this all assumes they havn't changed the design again of course.... I only bought mine about a month ago, but the pins seem to measure the same as Arny's IC versions so I'm guessing its probably the same....maybe....  For someone like me who is just measuring/building speakers at a hobbiest level this Mic would seem to be bargain of the century, as I've been casually looking around for some kind of measurement mic for quite a while now, and only stumbled across the ECM8000 *after* finding the DEQ2496, deciding to get one, and then seeing they had a recommended microphone to go with it If you do pick up another new one be sure to let us know the results...(don't open it up though Regards, Simon |

om "Arny Krueger" wrote in message ... "Ken Kantor" wrote in message om Based on terminal measurements, none of my ECM-8000's appear to have transformers. To verify, I actually opened one up this evening. Needless to say, I messed it up, since the wiring is very tight inside. Been three, done that. Mine was transformeless, too. All of mine are less than a year old. Two are functioning as choir mics. Here's picture of the elusive?? transformer equipped ECM 8000: http://www.imagendv.com/altavoces/micro_med.htm This is like a mod-ka-teer artical. You've lost me. You think this is a one-off mod? I only use a Rolls pass-though phantom power box when I want to run mics directly into my AP. The tests I just cited used the Behringer Ultragain 2000, the good, pre-tube one. (Input Z is flat at 3K. I have to say, though, that I haven't bought one of these mics in a few years, and so I can't be sure the design hasn't changed. Next time I am in GC, I will pick one up. Buying from GC is IME slow death. Everything takes at least an hour. Musician's Friend and competitors are more to my liking. It might take a couple of days of lead time for delivery, but I usually can plan that well. When I did my comparison I compared it to a DPA 4007 using the two channels of a Symmetrix 202, running into a LynxTwo. The Your sentence cut off. The Symetrix 202 is a decent amp, with a slightly higher input resistance than my preamp, so I don't know where your rolloff is coming from. It may be due to a rise in the mic I was comparing to - the DPA 4007 Electret capsules like the ECM-8000 uses, have no trouble achieving flat LF output, if the acoustic input levels are not extreme. Maybe it is time to re-test your mics??? I don't have the 4007 anymore - the (corporate) owner wanted it back. |

Good point! The best luck I have had in this regard (ie- no futzing)
has been with the plastic GR adapters such as came with the "OmniCal" 1986. How do your the ECM-8000's look against your (Larsen-Davis, I assume) standards? -k Herb Singleton wrote in message ...

Sorry for jumping in but I am in the process to buy a new mic + soundcard and have looked at the ECM-8000. Does anyone know if the frequency response curve presented in the manual is typical of the mic or does it measure different from that curve? I know that there might be individual variations between mics, but not how large ones that can be expected. T |

I compared them with the TerraSonde ATB's stock Type-2 mic (which in turn has been measured by a 3rd party calibration lab) using substitution methods. I've found the ECM-8000's to be +/- 1 to 1.5 dB from 100 Hz to 10kHz. As with Arny I've found a low-frequency rolloff, but (as mentioned in this threat) it seems to be dependent on the amp. The one interesting thing is that even though all three mics were fairly flat, the response curves weren't consistent. It looks like you can't just substitute one ECM-8000 for another and expect the same response - but it will be close. -- Herb Singleton Sound & Vibration Measurements http://www.cross-spectrum.com |
