so, will the bat box 9v with the switch for bass filter on and off that I bought for my
"corpsesound binaurals" work with DPA 4061's to increase the spl handling?
Why are you currently brickwalling the DPA's, whats the setup?
As for the question I don't know for sure but I don't think you use a standard Core Sound Battery Box
DPA 4061's are what they use in their High End Binaurals and from the CS website:-
"Due to different voltage requirements, the HEB battery box is not compatible with the battery box used with the Core Sound Binaural or Core Sound Stealthy Cardioid microphones."
I think this is due to the modification CS does to powering the capsule (?Linkwitz)
But you can use a standard Sound Professionals battery box provided you have a 1/8" jack on the DPA's.
As to wether this increases spl handing of the mics it depends on what you're using as powering at the moment. DPA spec sheets quote a power requirement of between 5-50V (NB USING their adaptors DONT try phantom power without an adaptor and say I told you it was okay
) so thats not particularly helpful but I've certainly read anecdotal reports that they sound better with the 9volts that they get from SP battery box.
However a number of people seem to be using them with the microtrack 1/4" TRS taking power (?5V) from the 1/8" socket and getting good records so maybe you'd have to try a 9V battery box and see if it's better than your current setup.
