Microphones
The plug-on measurement microphones combined with the
XL2 Analyzer form a comprehensive sound level meter and
acoustic analyzer. The microphones are 48 VDC phantom-pow-
ered and include an electronic data sheet.
Integrated Preamplifier
The microphone bodies contain a preamplifier and require
48 VDC phantom power supply for operation. They combine
high dynamic range and wide frequency range with low noise.
The measurement microphones can also be connected to the
XL2 Audio and Acoustic Analyzer using an ASD Cable for mea-
surements at remote locations or for reduction of acoustic re-
flections.
Electronic Data Sheet
The microphones include an electronic data sheet. The Auto-
mated Sensor Detection (ASD) of the XL2 Analyzer automati-
cally reads this data, i.e. the microphone model and calibration
data. This promotes faster setup and ensures accurate mea-
surements.
