User manual MARTIN AUDIO LE1200S SCHEMATICS

[. . . ] High frequencies are reproduced by a 1. 4" (35mm) exit titanium diaphragm compression driver loaded by a proprietary differential dispersion 50°-100° horizontal x 70° vertical horn. The differential dispersion horn varies its horizontal dispersion from wide to narrow as the performer moves back from the monitor. This narrowing dispersion effectively changes the forward gain of the horn which enables the horn to throw further, increasing the operating range of the monitor and reducing excess spill. [. . . ] As the performer moves closer to the monitor the dispersion widens giving the performer the ability to hear themselves clearly even when positioned directly above or to the left or right of the monitor. The multi-angled enclosure is of multi-laminate birch ply construction and is available in left and right-handed versions. Incorporating a tough punched 2 Martin Audio ­ LE12JB SERIES MONITOR CONTENTS < > ENGLISH PRINT GUIDES steel grille and recessed side handles, the cabinet is finished in black textured paint. When operated in passive mode the LE12JB can be used without a controller. Used actively the LE12JB is best operated with DX1 or MX5 controllers to provide crossover, limiting and eq functions. In either mode sound quality is consistent, enabling mixing of configurations on stage, without the need to compensate for differing tonal balance. When using the LE12JB in active mode performance is identical to its predecessor, the LE12J.
