The 1100‑LFC low-frequency control element is a self-powered loudspeaker defined by its sonic linearity in reproducing low-frequency transients at high, continuous output levels with very low distortion. This ultralow distortion, coupled with exceptional headroom and optimized rigging options, makes the 1100‑LFC a flexible tool for low-end directional applications for large-scale tours and installations.

To guarantee optimum performance, 1100‑LFC systems must be designed with Meyer Sound’s MAPP Online Pro® acoustical prediction software. The intuitive, cross-platform application accu‑ rately predicts directional patterns, frequency and impulse responses, and maximum peak SPL for 1100‑LFC systems, ensuring that systems de‑ liver the required coverage and SPL.

An optimally tuned, vented cabinet houses the 1100‑LFC’s two linear, high-excursion 18‑inch cone drivers. The loudspeaker’s 28 Hz to 100 Hz operating frequency range complements MILO®, MICA®, JM‑1P and other Meyer Sound loudspeak‑ ers, allowing it to integrate seamlessly with line arrays and curvilinear arrays.

The unit’s power amplifier operates at voltages 1100-LFC : Low-Frequency Control Element DATASHEET from 208 to 235 V AC, at 50/60 Hz. TruPower® limiting ensures maximum driver protection, minimizing power compression while yielding high constant output under high continuous and peak power conditions. The amplifier, control electronics, and power supply are contained in a single field-replaceable module located on the rear of the cabinet.

Protective, plastic skids are included on the bottom of the 1100‑LFC cabinet that securely align with the cabinet’s top slots. Units can be stacked normally or reversed for cardioid configurations.

The optional MRK‑1100 rigging kit, available as a factory-installed option or field upgrade, includes captive GuideALinks™ that allow the loudspeaker to be flown from the MTG‑1100 top grid. The GuideALinks, located at the front and rear of the cabinet, are easily set with convenient, pinned handles and slots. The GuideALinks also accommodate reversed units for flown cardioid arrays.

The optional MTG‑1100 top grid can suspend line arrays comprised of up to 12 cabinets at a 7:1 safety factor, or up to 16 cabinets at a 5:1 safety factor. The optional MAS‑1100 array spacer can be placed between cabinets to lengthen 1100‑LFC arrays, improving vertical directionality. For touring and portable systems, the 1100‑LFC can travel securely in stacks of three units with the optional MCF‑1100 caster frame. Durable nylon covers, accommodating stacks of two or three units, are optionally available to ensure the 1100-LFC is completely road ready.

Meyer Sound’s RMS™ remote monitoring system comes standard with all 1100‑LFCs and provides comprehensive monitoring of system parameters on a Windows®-based computer. Convenient 5-pin XLR connectors allow the use of composite cables carrying both RMS and balanced audio (3‑pin XLR audio connectors are also available).

The 1100‑LFC cabinet is constructed of multi-ply hardwood and coated with a blacktextured finish. A hex-stamped, steel grille with acoustical black mesh protects the unit’s drivers. Other options include weather protection and custom color finishes for fixed installations and applications with specific cosmetic requirements.
