User manual MARTIN AUDIO LE1200 SCHEMATICS

[. . . ] A differential dispersion horn varies its horizontal dispersion from wide to narrow as a 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. For optimum performance, it is recommended that the LE Series monitors in active mode are used with the MX5 System Controller or an appropriate digital controller such as the Martin Audio DX1. Please refer to the appropriate controller user guide for information on connections and correct limiter settings. 2 Martin Audio ­ LE SERIES CONTENTS < 3. 1 > LE350A ENGLISH PRINT GUIDES The LE350A is a low-profile monitor with differential dispersion horn technology and a 12" (305mm) bass driver. [. . . ] Please refer to the appropriate controller user guide for information on connections and correct limiter settings. 2 Martin Audio ­ LE SERIES CONTENTS < 3. 1 > LE350A ENGLISH PRINT GUIDES The LE350A is a low-profile monitor with differential dispersion horn technology and a 12" (305mm) bass driver. It is normally supplied as a passive system, available active to order. It can be configured as a left or right-handed monitor by unscrewing the baffle and moving the horn to the required end. 3. 2 LE1200 Featuring differential dispersion horn technology, the LE1200 utilises a high sensitivity 12" (305mm) bass driver and a 1. 4" (35mm) exit titanium diaphragm compression driver. It is an active 2-way system and is supplied in either left or right-handed versions. It is capable of extremely high output levels for its small size and its horizontal coverage pattern of 100 degrees at close range and 50 degrees at distance is ideal for stage monitor situations. 3. 3 LE400C The LE400 has become the industry standard wedge monitor. The LE400C utilises a 15" (385mm) bass driver and a high frequency compression driver mounted on a 40 x 70 degree horn. It features a twin-angle enclosure design, a rotatable baffle to avoid the need for dedicated left and righthanded versions and a switchable active/passive crossover. 3. 4 LE700A The LE700A is an active 2-way monitor with a high power 15" (385mm) bass driver and a 1. 4" (35mm) exit compression driver mounted on a differential dispersion horn.
