User manual MACKIE MR4WT QUICK START

[. . . ] MONITOR MR4T/MR4WT Compact Two-Way Speaker Quick-Start Guide The MR4T (Black) and MR4WT (White) are a compact two-way speaker system designed for constant-voltage systems. The 4. 75" carbon fiber woofer, in combination with a 0. 5" mylar dome tweeter mounted on a 120° x 100° constant-directivity horn, provide natural, smooth sound reproduction, ideal for use in business music systems and indoor/outdoor background music applications. The passive crossover is designed to reduce heat dissipation and optimize the power response of the loudspeaker. [. . . ] Installation ­ Do not install this Mackie Industrial product in any way that is not provided for in the instruction manual. Stacking multiple units ­ To prevent the danger of falling equipment, never stack multiple units of this Mackie Industrial product unless this possibility is expressly indicated in the instructions. Respect the safety standards ­ The entire sound system must be designed in compliance with the current standards and laws regarding electrical systems. 8. Specifications ­ When installing and using this Mackie Industrial product, keep in mind the technical specifications indicated in the dedicated section of the manual. Accessories ­ Install and use this Mackie Industrial product only with the accessories specified by the manufacturer or supplied with the product. Hearing loss - Exposure to high sound levels can cause permanent hearing loss. The sound pressure level which leads to hearing loss varies considerably from one person to another, and depends on the duration of exposure. Government's Occupational Safety and Healt Administration (OSHA) has established the maximum sound pressure levels that can be with stood without causing damage, which are shown in the table below. According to the OSHA regulations, any exposure over the maximum limits indicated in the table can reduce the hearing capacity of a person. To prevent potentially dangerous exposure to high sound pressure levels, anyone subjected to such levels must use suitable protection. When a Mackie Industrial product capable of producing high sound levels is being used, it is therefore necessary to wear ear plugs or protective earphones when the limits shown in the table are exceeded. Consult the specifications provided in the instruction manual to know the maximum sound pressure (SPL) the speaker is capable of producing.
