Meyer Sound LEO
Raise the bar with award-winning stadium systems for concerts and outdoor festivals.
Experience LEO: Large-Scale Linear Line Array Loudspeaker
Experience LEO — the Meyer Sound flagship line array system that remains linear and predicable across all frequencies and at very high sound levels.
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.
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.

MANUFACTURER NOTES
Loudspeaker system predictions for coverage and SPL are available in Meyer Sound’s MAPP System Design Tool.
Recommended maximum operating frequency range. Response depends on loading conditions and room acoustics.
Linear Peak SPL is measured in free‐field at 4 m referred to 1 m. Loudspeaker SPL compression measured with M‐noise at the onset of limiting, 2‐hour duration, and 50‐degree C ambient temperature is <2 dB. M‐noise is a full bandwidth, (10Hz–22.5kHz) test signal developed by Meyer Sound to better measure the loudspeaker’s music performance. It has a constant instantaneous peak level in octave bands, a crest factor that increases with frequency, and a full bandwidth Peak to RMS ratio of 18 dB. Pink noise is a full bandwidth test signal with Peak to RMS ratio of 12.5 dB. B‐noise is a Meyer Sound test signal used to ensure measurements reflect system behavior when reproducing the most common input spectrum, and to verify there is still headroom over pink noise.
Peak power based on the maximum unclipped peak voltage the amplifier will produce into the nominal load impedance.
AC power cabling must be of sufficient gauge so that under burst current rms conditions, cable transmission losses do not cause the loudspeaker’s voltage to drop below the specified operating range.
