User manual MARTIN AUDIO W8LCI SCHEMATICS

[. . . ] It is also provided with a top hat fitting for use with a tripod or as a pole socket for mounting above a Blackline subwoofer. Use of a controller with the F8 is optional. For demanding applications, use with an M3 or DX1 electronic controller is recommended. 3. 2 F10 Full-range system (Fig 2) The F10 is a 2-way passive system, designed to provide exceptional club sound reinforcement and stage monitoring from a very compact enclosure. [. . . ] It can operate in either passive add-on mode using its own internal switchable passive network or may be used actively with an M3 or DX1 controller. In the active configuration, the controller will provide crossover, EQ and limiter functions for the S12 and F8/F10 combination. Please refer to the M3 or DX1 user's guide for further information. The S12 is provided with a top hat fitting that can be used as a pole socket to mount an F8 or F10 above the enclosure. 3. 4 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 then gently levering the grille out of the side channels. 4 Martin Audio ­ Blackline F8, F10, S12 CONTENTS < 4 > ENGLISH PRINT GUIDES 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 a high level. Tripod Mounting The F8 and F10 incorporate a pole mounting socket to facilitate mounting on tripod stands. It is important to understand that a low power amplifier driven into clipping is more likely to damage a loudspeaker than a higher power amplifier used within its ratings. This is because music signals have a high peak-to-average "crest" factor. When an amplifier is severely overdriven, its output waveform is clipped (its peaks are squared off) ­ reducing the crest factor. In extreme cases, the waveform can approach that of a square wave. An amplifier is normally capable of producing far more power under these conditions than its undistorted rated power output. The use of very high power amplifiers with outputs greater than those recommended is discouraged. Care should be taken to avoid switch-on surges, which can result in momentary power peaks in excess of specified ratings. When powering up a sound system it is important to switch on the amplifiers after the mixer and control electronics have stabilised. When powering down the system, reverse the sequence and switch off the amplifiers first. 6 Martin Audio ­ Blackline F8, F10, S12 CONTENTS < 6 > ENGLISH PRINT GUIDES CONNECTIONS Each connector panel has two Neutrik Speakon connectors wired in parallel with each other. The second connector allows use of a short link lead to power another parallel loudspeaker. The connectors are wired as follows: F8/F10/S12 Passive (Fig 4) 7 CABLE LENGTHS When connecting Blackline systems to an amplifier, it is recommended that the return resistance of the cable used is less than one tenth of the nominal impedance of the system or systems in parallel. [. . . ] This configuration will present a 4 ohm load to the amplifier. An M3 or DX1 controller for this passive configuration is optional ­ just performing limiting functions without any additional system EQ.
