Confirmed its the 4-pin mini-XLR. The entire rig looks similar to the one jefflester posted.
Core Sound doesn't seem to provide any other battery boxes other than the one i have. Sound Professionals does seem to have some smaller ones, but they all tend to terminated in a 3.5mm headphone jack. Unfortunately I don't have the know-how to make my own at this time.
Any other stealthy off-the-shelf suggestions? Or does someone do work to change the termination on the DPA4061s from the 4-pin to a 3.5mm? Not even sure if that would work.
thanks in advance!
Yes, that photo shows the standard CoreSound setup. Thanks Jeff.
Yes, reterminating from 4-pin mini xlr to stereo 3.5mm minijack will work and will be required to use an alternate battery box.
Best option would seem to be a replacement CoreSound battery box as long as the previous one that's no longer working suited your needs. I'd contact Len at CoreSound about a replacement, and ask if they might take a look at your old one. They may be able to repair it. If not they should be able to supply a new one. Either way, no modification of the existing wiring will be required.
The CoreSound wiring scheme in and out of the battery box is somewhat clever and unique, and advantageous in a few ways. There is only one wiring cable needed which remains attached to the mics, the battery box uses just a single connector (most will have separate input and output jacks), and that connector is a positive locking type (mini-xlr).
To use a different battery box other than the CoreSound one you'll need to have the mics reterminated, replacing the 4-pin mini-xlr with whatever input connector is used by the new battery box. Stereo 3.5mm mini-plug is the most common connector type for that. The cables from both mics will be unsoldered from the mini-XLR and resoldered to the new connector. Not difficult, but somewhat fidgety and requires proper soldering skills. Any other battery box will then use an additional separate cable out from the battery box and into the recorder - typically terminated with a stereo 3.5mm plug at either end.
A 9V Sound Pro's battery box will work and may be smaller than the CoreSound box. I'd not choose one that provides any higher voltage as that could damage the mics. It is likely to have a stereo 3.5mm mini-jack input and separate stereo 3.5mm mini-jack output. Those connections are not likely locking types, but if they are you'll see threads around the outside of the jacks and could have the mics reterminated to a locking 3.5mm mini-plug if retaining the positive locking feature is important to you. Realize that if going this route you will have three mini-jack>mini-plug connections in the signal chain instead of just the single one you now have (into the recorder itself) along with the locking mini-xlr. Connections are common points of failure, so it can be wise to gaff tape non-locking connections into and out of the battery box to assure nothing comes loose while recording if you choose to go this route.
And to clarify how locking mini-jacks work- A standard non-locking male mini-plug will fit into both locking and non-locking female minijacks. A locking male mini-plug incorporates a female threaded ferrule that screws onto the threads surrounding a locking mini-jack, secureing the two.
