The Meyer Sound MSL-10A is an extremely high-power, high-performance loudspeaker system designed for large-scale music reinforcement and public address applications. The MSL-10A system comprises an all-horn, integral full-range loudspeaker cabinet constructed as a 30-degree arrayable section, and a 19" electronics rack (on wheels) housing the M-10A Control Electronics Unit, three MS-10 Power Amplifiers and an Interface Unit.

The minimum standard MSL-10A configuration comprises two loudspeaker cabinets, each with its own electronics rack. Additional MSL-10A cabinets may be employed as modular 30-degree building blocks to increase the coverage and acoustical power of the system, providing extensive flexibility to meet specific application requirements.

The MSL-10A Loudspeaker cabinet is fortified for long-term reliability in outdoor installations, and is thoroughly inspected at several stages during assembly. Constructed of high-grade Finnish birch hardwood, the enclosure is resin-impregnated in critical areas, bonded with structural epoxy adhesive, and coated with a finish that tolerates cabinet swelling without cracking. Thermostatically-controlled environmental heating and cooling systems, which receive power from the MSL-10A Rack, ventilate the cabinet and stabilize its interior temperature.

The MSL-10A cabinet is internally damped and braced for maximum energy transfer and highly intelligible reproduction of voice and music - which is especially important in acoustically difficult environments. Internal and external steel bracing and integral all-steel rigging points ensure safe, efficient installation and integral forklift brackets ease handling.

Component Quality and Linearity
The MSL-10A Loudspeaker employs driver components whose design, construction and testing have been proven in over a decade of demanding professional use. The transducer magnetic circuits and suspensions have been optimized for maximum linearity, resulting in extremely low harmonic distortion and consistent sonic accuracy at all dynamic levels. Ferrofluid cooling and aback-vented gaps and pole pieces maximize power handling and water resistant treatment of all driver elements ensures greatest reliability in outdoor installations. Gold-plated contacts and stainless steel mounting hardware resist corrosion.

Rigorous Testing
The M-10A Control Electronics and MSL-10A Loudspeaker components are individually and fully tested at several stages of manufacture to ensure maximum reliability and minimum component failure.

Each Driver is subject to an eight-hour dynamic burn-in test for power handling and peak excursion performance and thorough computer-based testing prior to shipment snsures optimal system operation upon installation.

Finally, the MSL-10A System has undergone years of field testing in stadium installations and touring reinforcement, resulting in a mature, refined technology that offers unmatched performance.
