Meyer Sound LEO-M Powered Line Array Loudspeaker
Meyer Sound LEO-M Powered Line Array Loudspeaker
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.
Features:
- Optimized line arrays with controlled directivity for even coverage and consistent responses over long throws
- High peak power output with exceptional linearity and transient reproduction at extreme levels
- Self-powered for simplified setup and increased reliability
- Optimized rigging allows splay angles to be set while stacks rest in caster frames
- Integrates seamlessly with 1100-LFC, LYON, and MIC
