DPA 4063 Low Sens. Low DC
« on: July 17, 2012, 09:43:18 PM »
Has anyone tried these yet...They only need 3volts to power them.  Sounds like a pair conected to a stereo mini plug would work with a R09HR or PCM-10 direct without a battery box?  Any thoughts?  You can't get much smaller or better than this for what we do........

I have used these extensively with a Sonosax MiniR82.  Mine are wired to Binder connectors to use the 3V supplied by the MiniR82, which for some reason was designed to provide either 48V phantom or 3V rather than the more useful 5V which would have allowed me to use 4060s instead.  I mostly low-pass this omni signal to boost the bass on a main pair of 4099s, but the times I have used the 4063s > MiniR82 alone the results are comparable (allowing for the reduced sensitivity) to what I get with 4060s through a DPA MMA6000 preamp, for modestly loud stuff (have not tried it on clavichord music).

If I remember correctly, I think the 4063 has comprable sensitivity to the 4061. 

I've also wondered if they will work correctly powered by the lower Voltage PIP provided by typical low cost Edirol/Sony/Tascam/etc. pocketable recorders.  The MiniR82 is in it's own category and Jeff is the only one I know of who has used the 4063.  Now that the preamps are getting clean and quiet enough on those inexpensive recorders, this is certainly something worth looking into.

i just got the Nagra SD Recorder to replace my old Korg MR-1.  Its super slim, very sturdy, very easy to operate and supposed to last 10 hours on two aa-batteries. 
Also it can power my DPA 4061 just fine. :)
This is super stealthy gear and you can also use the AGC-control if youre uncomfortable with resetting the levels during  the show.
Haven't tried it out in the field yet, will do soon :).

^^^ I have been curious about this recorder.  Maybe you can post some details about it?  Things like ease of use, build quality and materials, a battery test, etc.?  Also, how are you terminating the 4063s?  It looks like the SD has separate left and right 1/8" inputs.  Did you just terminate each mic with an 1/8" mono male?  Or get microdot to 1/8" cables?

I have the DPA DAD6027 connectors which terminate the mirodot cables into 1/8" mono male.
The Right Input is mic in, the left is line-in. Theres no power coming from the line-in (so only tried out a one channel as stereo recording for now).
I ordered a 2 x Mono 1/8" to 1 x Stereo 1/8" Y-Apapter to connect both mics - hopefully both will be powered....
However the Nagra Stereo Cond. Mic is plugged into both inputs - i dont know if this is for power supply (perhaps they're bridged in some kind??)
or just to make sure the mic is plugged in stable.

I usually use the MMA-6000 as preamp.
I was just surprised that the recording sounded very decent even without using the preamp.
When powering the DPA 4061 with the Korg MR-1 theres so much noise you wouldnt even want to
start recording.

The housing is top notch - only the battery lid is made of plastic and it seems like this one can break very easily - and if it does the batteries will jump-out by themself.
Usability is very easy - only flaw i found so far is the position of the hold button (small slide on the back, not on the side - so very hard to to set on and off)
Havent tested anything else yet.

Would it be this one?

Yes that is it.
Just did a three hour non-stop recording with mic-power on. The Battery Indicator still shows "full power". 
So this is enough battery-life to tape even long shows without having to use external backup battery.

Files are being auto-split when file size of 2 GB is reached. The split is seamless.

I'm considering getting an unterminated pair of these mics, wiring them to a right-angle Neutrik stereo plug and using PiP on my M10.

Only four solder points (2 ground (shared), 1 left, 1 right), so it shouldn't be too challenging to somebody with basic soldering skills, right?
I may need to lay off the coffee for a week to be able to hold a soldering iron steady, though :x

Currently running DAB (dynamic audio binaurals) -> DA-120F (9V BB with 120Hz HPF) into the M10 (or R09), which has been my setup the past 4-ish years, so I'm feeling upgraditis :D

The coaxial shield/ground is easy to solder once separated from the reinforcing aramid fibers.  Stripping and soldering the super-fine signal wire is the bigger challenge.

You weren't kidding about the super-fine signal wire.  I ended up burning off
the insulation to solder.  Strange thing about the Neutrik right angle plug is
the ground contact does not have a hole to loop through, so I'm less certain about that solder point.

Things seem to work with PiP out of the M10 at lower volumes, but the DC Offset as reported by SoX is higher than I'm used to (Haven't listened, yet, hearing is still off after a cold).
Thinking about it more, I don't think the M10 PiP off 2x AAs should be expected
to deliver 3V unless I'm using less-common (non-alkaline) batteries or change my batteries every 10 minutes.

But my cell phone battery is 3.7V :D

Digital recording devices would rarely run directly from battery.  Typically they need a 3.3V supply which is generated from a DC converter.

I thought I posted this earlier, but maybe I only hit preview instead of post :x

So with my home stereo maxing out around 104-110 dBC, PiP off the M10 seems fine powering these.  I might be OK without a battery box for many of the shows I go to.  DC offset stayed at 0.000030, which is what I'm used to from my reference DAB > DA-120F > line-in setup, too.

I hit 129 dBC by screaming into the 4063s and DC offset jumps to -0.003368.
But I don't think I've ever hit those levels at a show, not even Mogwai(*).
I measured softer yelling into them at 117 dBC with DC offset of -0.000474.
These might be from having the levels up too high, and my voice is already gone.
My screams and yells are unlistenable regardless, so I can't give comments about
audio quality, either.

Even for most rock/metal shows I go to, the loudest levels from my DAB setup (head-mounting over ears) are from people screaming and clapping near me; so maybe I'll be OK.  I will need to learn to dial in the Mic-In levels on the M10...

I'm using a Galaxy Audio CM-140 SPL meter for dBC measurements, and that seems to max out at 130dB (not sure if that spec is A/C weighted), so maybe my scream measurements aren't very accurate.

DC offset was reported by SoX.

M10 settings: level: 4, mic sens: lo, limiter: off, 24-bit@48kHz

(*) the loudest band I've seen/recorded.  But Mogwai doesn't seem as loud as they used to be.  I wonder if:
a) they lowered their levels over the years
b) I'm favoring positions close to the stage and avoiding room gain/PA coverage
c) they are playing smaller venues with weaker PAs
d) my hearing is less sensitive nowadays :x
I remember folks without earplugs covering their ears and crouching down at the Wiltern back in the day (but I wasn't a taper back then).

DC offset at those levels is not a concern.  The problem you will have from levels in excess of headroom is clipping, not DC offset.  It's possible for asymmetrical clipping to register a small DC offset, but that is not the primary issue.
