DIY batterybox for dpa 4061 (iso: schematics?) edit: Now with pictures!

[dabbler]

Actually, I've been hoping to switch to the EBL 9V Li-ions which are only 8.4V.
I would get a nice weight reduction, too.

Hi here this is official DPA 9 Volt schematic

sorry to dig up old thread. does it matter which way cap goes in this schematic? firmdragon's sketch has the + facing the mics, DPA schematic doesnt specify. Also in headroom's post here:

https://taperssection.com/index.php?topic=94046.msg1397122#msg1397122

he suggests using a 470 uF 10V cap, which seems way different. what is the effect of changing the capacitance by so much?

anybody know where to get female microdot panel connectors (or somethign small i could pot)

like this, but in the US

Found this just by Googling, $112 apiece.

i should have added affordable! i see a few stateside for $30-$50, and ones from china for $2. theres gotta be a middle ground

If you're hearing distortion, it's not from the DPAs.

Even 10k Ohm is marginal in protecting the capsule. With a fresh, so-called "9 Volt" battery (which can really measure as much as 9.6 Volts), you risk damaging the capsule.

With 4.7k you'll almost certainly eventually damage or destroy it.

is it always wise to limit current to less than the capsule maximum? in this case is the capsule max current the max it will draw, or the max it should be allowed to draw?

Here's the battery box I use.  Works flawlessly with my DPA 4061's.  This BB is super tiny.

so it took me a while to sucessfully test it out.  but here's some a pic of what it looks like and how it compares to a soundpro SP-SPSB-1.

edit:
I used a piece of veraboard and used a female mini-jack from an old soundcard.  the resistors and cap are all pretty common.  all held in togethor with hot glue.  in hindsight,  i should have used an old headphone male mini-jack instead of regular wire and that new gold jack.  the fact that the gold jack isn't a right angle plug also kinda sucks. also a some sort of housing for the battery probably wouldn't be a bad idea either.  one time between sets, i couldn't figure out why i wasn't getting levels, turned out the battery had become disconnected from the bb.

questions, comments, suggestions? all welcomed.

I think the sp 11 used to be quite similar in size...had the roll off switches, but was tiny and had a nice " sled" that the 9v fit into.  They're not making it any longer...

Not true.  Sound Professionals still makes the SPSB-11.  However, its slightly bigger than the SPSB-10.   SP-10 is the way to go, imo.  Ultra tiny setup.

According to Len 12 V will kill your 406x in short order

Well, the 11 USED to be smaller. Also, it was a 9v.

theres a somewhat spendy mps6040 batt box on reverb right now

They used to sell this box as the SP-SPSB-10 back around 2008, my original rig had one. When I replaced it in 2012 I noticed that they now sell that box as the SPSB-11 and the new SPSB-10 is the same box but without switches
