Outdoor Microphone
Always activate the frequency correction fil-•
ter in the XL2 when measuring a horizontal
sound incidence (sound source from the side)
with the M2230-WP. The filter ensures that
the measurements accuracy meets the class
1 requirements of IEC 61672 and ANSI S1.4.
Deactivate the filter only if you are measur-•
ing a vertical sound incidence (sound source
from above e.g. airplane noise).
The outdoor windscreen is recommended to •
be replaced annually. The “WP30 Windscreen
Replacement” includes two spare wind-
screens, NTi Audio # 600 040 061.
The water-repellent membrane in the top sec-•
tion is mounted with two O-Rings. Inspect
these O-Rings and the membrane annually
for proper seating and good condition. Do not
touch the water-repellent membrane.
Do not use the M2230-WP in a horizontal po-
sition. Raindrops may reach and damage the
M2230 measurement microphone.
