[. . . ] The S218+ is designed to be used as part of a high power active system. It must be electronically crossed over with a Martin Audio M3+, DX1, DX2 or Engineer system controller. 3. 5 Grille removal To remove the grille, first remove any grille retaining screws. The grille can then be removed by inserting a flat bladed screwdriver under one of the notches at the top and bottom of the grille and gently levering the grille out of the side channels. 4 Safety first It is important that loudspeaker systems are used in a safe manner. Please take some time to review the following points concerning safe use of Blackline Series loudspeakers. 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 Pole or stand mounting Blackline+ full-range loudspeakers incorporate pole mounting ("top hat") sockets so that they may be pole or stand mounted. All material © 2007. Subject to change without notice. When using poles or stands, the following precautions are advised: Ensure that the stand will support the weight of the speaker by checking the stand manufacturers rating. (See the Section 10 ­ Technical Specifications - for individual Blackline+ weights and dimensions) Make sure that the stand is placed on a level surface and that its legs are fully extended Do not place more than one speaker on each stand Run cables so that they do not present a trip hazard which could pull the speaker over When used outdoors in the wind, it may be necessary to add some weight to the base of the stand When using a pole mount with a sub-bass system, observe similar precautions. 4. 2 Stacking Ensure that the floor or stage is level and solid Do not stack speakers too high outdoors where winds could topple the stack Be aware that speakers producing very high power levels can move or creep. To avoid this, place friction material between the floor and speaker and between each speaker. 4. 3 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. Blackline+ Series enclosures are designed for portable applications, but can be suspended singly by means of the threaded inserts provided. Enclosures are fitted internally with steel corner reinforcement brackets, where necessary, to ensure that each cabinet is strong enough to be hung from its top. 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. Only forged shoulder eye bolts should be considered and it is important that the thread length is at least 30mm Formed eye bolts i. e. those which are formed from a steel rod bent into an eye are not recommended A flat washer should be inserted between the eyebolt and the enclosure Eye bolts are strongest along the thread axis. Angling the enclosure will result in an angle pull and it is important to use eye bolts that are safe in these circumstances. 5 Amplification Choosing a power amplifier Martin Audio loudspeakers are capable of recreating musical dynamics accurately and with incredible impact if powered correctly. Martin Audio loudspeaker power ratings are quoted for AES power - a longterm average power rating, and Peak power ­ a short-term burst capability. Moving coil loudspeakers can be run up to their AES power rating continuously and up to the higher Peak All material © 2007. Subject to change without notice. power rating for transient musical peaks. 1) Choose amplifiers capable of delivering the loudspeaker's Peak power rating ­ see below 2) For good spectral balance, set your amplifiers to the same voltage gain throughout the system. [. . . ] Martin Audio loudspeaker power ratings are quoted for AES power - a longterm average power rating, and Peak power ­ a short-term burst capability. Moving coil loudspeakers can be run up to their AES power rating continuously and up to the higher Peak power rating for transient musical peaks. Choose an amplifier capable of delivering the loudspeaker's Peak power rating Use the M3+'s carefully timed limiters to avoid exceeding the AES long-term power rating. This policy avoids clipping transient peaks. [. . . ]
