QUICK GUIDECommission an Installed Sound Environment
Play the cyclic PNOISE from the MR-PRO through your sys-
tem. Adjust the gain of your system and your MR-PRO so
that there is enough energy to reach the top of the Level
markers in as many frequency bands as possible on the
XL2. WARNING: It is advisable to wear hearing protection.
Hint: You may have to increase the bass frequencies on your
system. Even so, it is often impossible to create enough en-
ergy in the 63Hz frequency band.
On the XL2, press the Play button.
The status (STAT) changes to ARMED. Each time a cycle
is completed by the MR-PRO, the AVRG value increments.
Take at least 3 measurements ensuring that each frequency
band displays a tick mark after each measurement cycle
(except maybe the 63Hz band).
On the XL2, press the Stop button.
On the MR-PRO, press the mute button.
On the XL2, select Res from the second menu. The RT60
results are shown.
Select CYC to review the results of each cycle and delete
cycles that are dissimilar.
Save the test.
