Operate the measurement microphones with 24V phantom power?

Yes, the measurement microphones M2230, M2211 and M2215 can be operated at lower phantom power voltages than 48 VDC at special applications without the XL2 Analyzer. The lower phantom power voltage reduces just the maximum sound pressure level of the measurement microphone. All other specified parameters remain applicable.

Maximum sound pressure level @ THD 3%, 1 kHz, Rp*:
