    Always discuss the environmental conditions of your Meyer Standard Weather Protection Sound installation with your Sales Manager, and verify the Meyer Sound designs toward an IP rating of IPX4 (see “IP availability of Weather Protection for your selected Ratings” on page 41) for Standard Weather Protection, loudspeaker models.

  • Page 41: Ip Ratings

    OPERATING INSTRUCTIONS 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.

  • Page 49 CAUTION: There is only one proper loudspeaker orientation once the rainhood is installed. See Figure 48. CAUTION: The weather-protected LINA must be mounted with a 0 ° tilt, or preferably with a slight down-tilt. This angle shields the driver from the elements and does not allow water to accumulate. Do not tilt the cabinet up, as the drivers and cabinet will accumulate water.
