Meyer Sound’s 900-LFC compact low-frequency control element reproduces low frequencies at high, continuous output levels with extremely low distortion. The 900-LFC offers the same sonic linearity as Meyer Sound’s 1100-LFC low-frequency control element in a smaller, lighter cabinet, making it ideal for building scalable systems to suit touring applications or fixed installations of any size. A newly-designed class D amplifier affords unprecedented efficiency to the 900-LFC, significantly lowering distortion while reducing power consumption and operating temperature. The onboard amplifier and control circuitry are contained in a single, field-replaceable module. In addition to pairing with LEOPARD™ systems, the 900-LFC integrates easily with other Meyer Sound loudspeaker systems, including LEO-M™, LYON™, and ULTRA Series loudspeakers. LEOPARD and 900-LFC can be driven by Meyer Sound’s Galileo Callisto™ 616 array processor, which provides matrix routing, alignment, and processing for array components. To guarantee optimum performance, systems with the 900-LFC should be designed with Meyer Sound’s MAPP™ software. LEOPARD and 900-LFC loudspeakers work with Meyer Sound’s RMS™ remote monitoring system, which provides comprehensive monitoring of system parameters from a Mac® or Windows®-based computer. The 900-LFC is available with or without Meyer Sound’s QuickFly® rigging. When equipped with the optional MRK-900 rigging kit, the 900-LFC’s captive GuideALinks™ allow it to be flown from the MG-LEOPARD/900 multipurpose grid in LEOPARD arrays without a transition frame. 900-LFCs can also be flown separately as a subwoofer array with variable splay angles from 0 to 5 degrees. The MG-LEOPARD/900 grid can also be used for groundstacks with uptilt or downtilt. Both versions of the 900-LFC can be transported in stacks with the optional MCF-900 caster frame. MG-LEOPARD/900 Multipurpose Grid Flies LEOPARDs, 900-LFCs, and mixed arrays. Also supports LEOPARD and 900-LFC groundstack configurations. PBF-LEOPARD Pull-Back Frame Provides pull-back for extreme downtilt of flown LEOPARD and 900-LFC arrays, and allows additional downtilt in groundstacked arrays. Callisto 616 Array Processor Drives and aligns Meyer Sound array systems with 6 x 16 matrix processing, delay integration, and EQ, using Compass software. MVP Motor Vee Plate Attaches to MG-LEOPARD/900 grid and fine tunes horizontal aim of LEOPARD and 900-LFC arrays. MCF-900 Caster Frame Safely transports up to two 900-LFCs, making it easy to assemble and disassemble arrays in blocks of two cabinets. MDM-5000 Distribution Module Integrates routing of audio, power, and RMS to loudspeaker arrays.
