Meyer Sound LEO Linear Line Array Loudspeaker
Linear Approach to Large-Scale Reinforcement
Unleash The Power of Linearity
Experience Meyer Sound LEO — the Meyer Sound flagship line array system that remains linear and predicable across all frequencies and at very high sound levels.
The Sonic Detail of Studio Monitors at Large Concerts
The system’s impressive transparency allows the audience to hear each instrument — vocals, bass, sax, drums, guitar — simultaneously and transparently, without one element coloring the others.
Tailor The Sound to Your Liking
When the tonality of your system stays consistent, you are free to create any desired effects upstream with plugins and know that your subtle enhancements will be reproduced accurately.
A System That Plays No Favorites
An inherently multipurpose system that is equally suited to classical music, heavy metal, electronic dance music, or anything in between.
Self-powered technology eliminates amplifier racks, long loudspeaker cables, and any calibration of gain and crossover settings. The system can be rigged and ready in minutes.
The LEO-M advanced linear array loudspeaker is defined by its sonic linearity at any output level. With exceptional headroom, extremely low distortion, and optimized rigging options, LEO-M forms the nucleus of Meyer Sound’s next-generation LEO array systems, conceived for long-throw applications. LEO arrays are ideally paired with Meyer Sound’s 1100-LFC low-frequency control element for bass reproduction, and the LYON linear line array loudspeaker for downfill. The MICA compact high-power curvilinear array loudspeaker is also well suited for downfill. Entire systems are driven by Meyer Sound’s Galileo Callisto 616 array processor, which provides matrix routing, alignment, and processing for array components.
To guarantee optimum system performance, Meyer Sound LEO array systems should be designed with Meyer Sound’s MAPP Online XT acoustical prediction software. The intuitive, cross-platform application accurately predicts coverage patterns, frequency and impulse responses, and maximum peak SPL for LEO array systems, ensuring that systems deliver the required SPL and ideal coverage for the intended audience areas.
Meyer Sound LEO -M’s high-frequency section is comprised of two proprietary compression drivers coupled to a constant-directivity horn through a patented REM manifold. The manifold’s smooth radiating characteristics afford tight vertical coverage. The low-frequency section includes two longexcursion cone drivers, also proprietary, capable of withstanding high, continuous output levels. Precise phase and magnitude alignment between low- and high-frequency drivers yields consistent and well-behaved system responses.
The unit’s power amplifier operates at nominal voltages from 208—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.
Meyer Sound’s RMS remote monitoring system comes standard with all LEO-M loudspeakers and provides comprehensive monitoring of system parameters on a Mac or Windows-based computer. Convenient XLR 5-pin connectors allow the use of composite cables carrying both RMS and balanced audio.
LEO-M offers intuitive rigging with captive GuideALinks that can be set to the desired splay angles while cabinets rest in caster frames.The MTG-LEO-M top grid flies arrays of up to 18 LEO-Ms at a 7:1 safety factor (with some restrictions). Optional transition frames are available for flying LYONs or MICAs below LEO-M arrays for downfill. Stacks of up to four LEO-Ms can be securely transported with the optional MCF-LEO-M caster frame; durable nylon covers, accommodating stacks of two, three, or four units, are available to protect the cabinets during transport.
The vented LEO-M 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. The cabinet is weather protected and includes a collapsible rain hood that shields user panel connectors from water intrusion.
