User manual MARTIN AUDIO EM26

[. . . ] For optimum performance, it is recommended that EM Series loudspeakers are used with EMX System Controllers ­ the EMX1A for the EM26/56/76 and the EMX2A for the EM186. The controllers can be switched between full-range and sub-bass operation and contain limiter circuitry activated by sense lines for loudspeaker protection. [. . . ] Professional loudspeakers are capable of producing extremely high sound levels and should be used with care. Hearing loss is cumulative and can result from levels above 90dB if people are exposed for a long period. Never stand close to loudspeakers driven at high level. 4. 1 Rigging and Suspension WARNING: Suspending the system should only be done by qualified personnel following safe rigging practices. Secure fixings to the building structure are vital. Seek help from architects, structural engineers or other specialists if in any doubt. The EM26, EM56 and EM76 are provided with rear panel fixings for wall brackets. The EM26, EM56, EM76 and EM186 are also fitted with threaded inserts to allow the suspension of a single enclosure. Never suspend one enclosure from another to form an array or cluster using these fittings. The common practice of using commercially available eye bolts for suspension should only be undertaken with great caution. Eye bolts are strongest along the thread axis. Angling the enclosures will result in an angle pull and it is important to use eye bolts that are safe in these circumstances. Only forged shoulder eye bolts should be considered and it is important that the thread length is at least 30mm. A flat washer should be inserted between the eyebolt and the enclosure. [. . . ] The sound balance of the complete system can be set up by using a screwdriver to adjust the trim controls accessible through the controller front panel. Please refer to the EMX1A or EMX2A User's Guide for further information. 9 WARRANTY Martin Audio EM Series products are warranted against manufacturing defects in materials or craftsmanship over a period of 5 years from the date of original purchase.
