Sound Level Meter
Level Difference
Prior to the start of the live event, the level difference between
the loudest and the measurement position is measured. The
XL2 Analyzer calculates the level difference automatically based
on the individual sound level measurements at both locations.
This level difference is included in the sound level reading dur-
ing the live event, and the XL2 thereby displays and records the
sound pressure level of the loudest point.
