10. Use only with a cart, stand, bracket, or table specified by the 

manufacturer or sold with the apparatus. When a cart is used, use

caution when moving the cart / apparatus combination to avoid

injury from tip-over.

11. Refer all servicing to qualified service personnel.

Servicing is required when an apparatus has been

damaged in any way, such as power-cord or plug

is damaged, liquid has been spilled, or objects

have fallen into the apparatus, the apparatus has

been exposed to rain or moisture, does not 

operate normally, or has been dropped.

12. To reduce the risk of fire or electric shock, do not expose this

apparatus to rain or moisture.

13. Hearing damage, prolonged exposure to excessive SPL, the 

loudspeaker is easily capable of generating sound pressure levels

(SPL) sufficient to cause permanent hearing damage to performers,

production crew and audience members. Caution should be taken

to avoid prolonged exposuro SPL in excess of 90 dB.

IMPORTANT SAFETY INSTRUCTIONS

 

 

The MG Series loudspeakers covered by this manual are not intended for fixed installation in outdoor or high
moisture environments. Moisture can damage the speaker cone and surround and cause corrosion of electrical
contacts and metal parts. Avoid exposing the speakers to direct moisture. Keep speakers out of extended or
intense direct sunlight. The driver suspension will prematurely dry out and finished surfaces may be degraded by
long-term exposure to intense ultra-violet (UV) light. 

The MG Series speakers can generate considerable energy. When placed on a slippery surface such as 
polished wood or linoleum, the speaker may move due to its acoustical energy output. Precautions should be

 

 

 

taken to assure that the speaker does not fall off a stage or table on which it is placed.

PATENTS

MG series products are manufactured and sold under U.S. patents 5,748,760; 6,112,847; 6,394,223; 6,847,726;
