Arni - what do the manufacturers' specs say about the different sensitivity of these mics??  That would yield the most useful info.  Tschuss.

DPA 4061:
Sensitivity, nominal, ±3 dB:
6 mV/Pa; -44.5 dB re. 1 V/Pa


MM-HLSC-1:
Open Circuit Sensitivity: 8 mv/pa +/- 2.5db


25dB are a fact ;)...my DPA 4061 where modded to a single 1/8"(3.5mm) plug by Chris Church, hope Chris didn´t put his 4.7k resistor to my mics ...just kidding ;D!


Where did you purchase these mics? I tested a bunch of mics for a fellow user here at T.S and some of them were WAY off spec. I dont remember terminating any other DPA mics for anyone else accept him. So you must have got a set from the same person. I gave him all the info on the mics as far as the sensitivity of each pair he had sent me over 7 pairs and I paired them as best I could. I do remember one pair being really bad, I am not trying to stir up any shit here, I just dont want people thinking I did some bad work. When all I did for this guy was test his mics and give him matched pairs as close as possible based on the mics this user provided me.

Chris

It´s "redbooks" DPA 4061 which you modded to 3.5mm.
He told me he sent them to you for cleaning and measuring and he also told me you modded them to 3.5mm.

-34db/-38db was written on a blue sticker when I got the mics....4db difference.
you remember chris?


Then they are 4db apart.. The sensitivity was not as good as some of the others I measured. That was measured at 1k with a 9 volt battery source into my computer audio interface with a 10k input impedance.

yeah chris, i know they are 4db apart, BUT where does the very low sensitivity come from?

AGE. And sweat. I would use a 1k tone and measure them both remember that your trying to compair a directional mic with a omni mic this test must be done with one speaker on axis no more then 4 inches away from a tweeter. To be accurate. make sure that each mic is held in the exact same position for the test. DO not use music as a source to compair microphone sensitivity especially when they have different polar patterns..

thx moke....redbook told me these mics were used at czech TV stations....that might be the reason for their insensivity......i payed 450$ for both mics.....
at least on mic-in they sound great for amplified rock shows. ;)

I had good luck here with the Broadway sellers, my dpa 4061's are faily well matched and have done great recordings for 2 years after purchase.

I also own a pair of MM-HLSC-1 as well as 4061's and I have experienced the same thing. My DPA's are from Core Sound so they were up to spec when I got them. The output from the MM-HLSC-1s are way higher than any other mic I have run. They run so hot that they are impossible to use with a AD-20 for any normally loud show without an attenuator cable. Using a -20db attenuator cable brings the output in the same ball park as the DPA's.

i run the dpa 4061 and the mma 6000, i dont know if it makes a difference between battery box and pre amp, but I aslo have a increased resistor in edirol r-09 for increased gain, so if i were to have my gain at 30 on edirol r-09 then i would need to put the mma 6000 on only about 2db as i would clip the sound

i am trying to record tonight

are the senn's cardoid pattern?

wouldnt that make soem difference in how the study shold be conducted as far as polar patterns

to me the DPA recordings with 4061 is cleaner( especially when using the mma6000) and fuller than with the senns when listening to a recording

what do other people think about the 2 in performance sound?

yes the senn´s are cardioids....i just wanted to say I can´t use my DPA 4061´s+12V bbox on line-in of the edirol  r09 even at full gain.... as I don´t get enough signal at loud amplified shows ;).

The DPA mma6000 amplifier is a wonderful piece of gear to have when running the dpa mini mics!! I don't use my mt2496 for gain control whatsoever - I totally use the mma6000 and have no problem whatsoever with having enough gain running line in...  I would suggest purchasing the mma6000 if you plan on keeping the dpa mics.

Not true - I manage it with no problem...  Maybe size really does matter.   :yack: :yack:

I used to have Church Audio's preamp for the 4061s and that is not much bigger than an Edirol R-09 and it should do the job just as good as DPA's own preamp. How about those who stealth with a JB3, that thing is big and heavy, in contrast to the R-09/iRiver/MD-recorders!  :P

my mics a 1/8" single plug terminated, maybe I´ll try them with my mm-preamp in 2 weeks.
