Electronic Data Sheet

MA220
Microphone PreAmplifier

The MA220 Microphone PreAmplifier includes an electronic data
sheet. The automated sensor detection (ASD) of the XL2 Analyzer
reads this data sheet, enabling the XL2 to automatically recognize
the preamplifier type and serial number, microphone sensitivity
and user calibration date. This ensures correct measurement results using the MA220 Microphone PreAmplifier with 1/2” microphone capsules.
