Schwillaby, I might have been to quick in my prior reply. I took "48 Volts" to mean a standard phantom power scheme with 6k8 drop resistors already in place. But if you build a power scheme for the DPA 406x from scratch I believe the formula you arrived at is correct and identical to that provided by DPA for these mics. Jon

Yeah they take a 9V battery but they can be dropped to 7V as well, no? Could I use my Sound Pro battery box for this? Just asking....the HEB box (made by coresound for the DPA406xs) in fact uses 9V and just a resistor + a capacitor for each channel (without dropping to 7V).Getting the sound pro battery box to work with the DPAs could be as easy as replacing the resistors with 10K ohm values (that's what HEB boxes use) and the capacitors will also probably need to be replaced with other values as well if you want to use the rolloff.
