Ip Ratings - Meyer Sound LINA Operating Instructions Manual

IP RATINGS

IP stands for "Ingress Protection." The current format for expressing an IP rating is a 2-digit code. The first digit of an IP
rating represents protection from solid objects. The second digit of an IP rating represents protection from water or
moisture. Table 5 provides a chart of IP ratings and the corresponding definitions of the rating.
NOTE: IP ratings only apply to the "ENCLOSURE." A loudspeaker is considered an enclosure and as such we
can apply an IP rating to it. Rigging hardware is not an enclosure and therefore IP ratings do not apply. Also,
cable and cable-mount connectors used to connect to the loudspeaker are NOT part of the enclosure and therefore
not part of the IP rating. Only the chassis-mounted part of the connector is considered part of the enclosure.
