Topic: Max SPL on Beyerdynamic MCE 10.11 N(C)

[sacchini]

After more than 15 years, I'd like to use again a pair of Beyerdynamic MCE 10.11 N(C)PV.
A long time ago I used them with battery supply (IEC 4 F 16, 5.6 V) but I've had overloading and brickwalling on high sound pressure level shows.
Now I'm going to use the same mics with phantom supply provided by my brand new Roland R-26.
Should overloading and brickwalling get better or can't I expect no improvement?
