To maintain signal integrity, the MDM-5000 distribution module offers LEO Family users a dependable and easy way to route AC power, audio, and RMS signals. LEOPARD delivers the same advantages of self‐powered design, linear response, and precise directional control as its bigger siblings, LEO‐MTM and LYONTM.

LEOPARD breaks new ground in loudspeaker array performance, providing exceptional phase coherence and consistent coverage in a light, compact cabinet. Its innovative amplifier, driver, and horn designs ensure that LEOPARD systems reproduce any sound source with linearity over a wide dynamic range, from speech and classical music to rock and EDM. LEOPARD loudspeakers offer Native Mode, a configuration optimized to yield excellent system performance right out of the box with minimal external processing.

Field-replaceable amplifier

A class-D amplifier affords unprecedented efficiency, significantly lowering distortion while reducing power consumption and operating temperature. A single, field-replaceable module contains the onboard amplifier and control circuitry. (See “Why Self-Powered?” below*)

Easy to configure

LEOPARD is portable and easy to configure. Its low weight and narrow profile make it well-suited for small- to medium-sized touring acts and fixed installations, where scalability and ease of rigging are essential. An array of six LEOPARD with two accompanying 900-LFC loudspeakers can be flown using only a ½-ton motor.

Low-frequency control

For low-frequency enhancement, LEOPARD loudspeakers pair with Meyer Sound’s 900-LFC low-frequency control element, which can be flown as part of LEOPARD arrays without transition hardware. Like LEOPARD, the 900-LFC also features an excellent power-to-size ratio, improved efficiency, and versatility.

Standalone or supplemental

In addition to working as a standalone system, LEOPARD can also be used as a supplemental fill loudspeaker in LEO-M and LYON systems. Applications that require more low-frequency headroom can use Meyer Sound’s 1100-LFC, which also integrates with LEOPARD systems.

Galileo® network audio platform

Drive LEOPARD systems with Meyer Sound’s Galileo GALAXY network platform, which provides 24-bit/96kHz audio, matrix routing, alignment, and processing for array components. To guarantee optimum performance, you can design LEOPARD systems with Meyer Sound’s MAPPTM System Design Tool, which effectively anticipates system SPL and coverage requirements, providing visual feedback of dispersion characteristics. This useful tool also helps verify rigging load ratings.

Remote monitoring—Mac/PC

LEOPARD and 900-LFC loudspeakers work with Meyer Sound’s RMSTM remote monitoring system, which provides comprehensive monitoring of system parameters from a Mac or Windows-based computer.

What the pros are saying about Meyer Sound LEOPARD

“LEOPARD brought the audience closer to the stage, giving the hall the intimacy of a club. This transformation is exactly what we aim for when we bring this type of music to a big stage.” — Gerhard Veeck, Technical Director, Moers Festival

“I was impressed by the way the sound was very even across the entire frequency range as you walked toward and away from the arrays. It was a much smoother progression, in both level and consistency of frequency response. To me, this marks a step forward in linear loudspeaker development and makes LEOPARD a bit of a game changer in the small line array category.” — Richard Brooker, Theatrical Sound Designer

“After listening to the LEOPARD system, I was not only surprised but shocked. I couldn’t believe a system so small and lightweight would have such enormous power and brilliant sound—not to mention the simplicity of the rigging and connections.” — Martin Štefanek, Managing Director, Hurricane

“LEOPARD is an exponential improvement in how we’re able to offer amplified concerts. The system can fool me into thinking the sound is not really amplified, even though I know it is–that feels like magic.” — Andrew Dubowski, Operations Director, San Francisco Symphony

“It was truly breathtaking the way the LEOPARD arrays could accurately recreate the unique, full-bodied sound of the London Symphony. LEOPARD’s linearity guarantees a transparent sound image, whether the orchestra is playing loud or soft passages.” — Ivo König, Co-Managing Director, IT AUDIO GmbH


*Why Self-Powered?

Self-powered loudspeakers offer several advantages over their passive counterparts when it comes to fidelity, reliability, and simplicity. The great part is, you’ll start to reap the benefits of a self-powered system before you even power up.

Ease of deployment: System set-up is so much easier when you have fewer components and fewer cables to worry about being miswired. Since self-powered loudspeakers incorporate amplification, you’ll never have to deal with matching speakers to amplifiers or connecting components. You don’t have to worry about calibration of gain and crossover setting which means more time focusing on the show. Eliminating amp racks doesn’t just streamline system deployment, it streamlines your inventory   whether you’re a rental house or a road warrior. And when you consider that the average amp rack weighs nearly 300 pounds and takes up four feet of truck space, the efficiencies get even clearer. Let alone when you want to fly the amplifier racks to get closer to the speakers, often requiring more rigging points and more motors.

Predictable, reliable operation: Internal amplification is closely matched to drivers. Because individual components have been optimized during manufacturing, you can expect consistent sound from show to show. Built-in, factory-optimized protection circuitry provides extra assurance without degrading signal quality. And, when you have less equipment, you have less risk of failure.


Better frequency and phase response: Because self-powered loudspeakers incorporate sophisticated processing, they are calibrated to exhibit optimal response curves in key performance parameters. Active crossovers are more precise, sophisticated designs, and bi-amped systems are time aligned, eliminating phase issues. The result? Accurate sound throughout the speaker’s range, at any volume level.

Unparalleled clarity: In, self-powered floor monitors internal amplifiers are precision-matched to drivers, delivering optimal power at all times for cleaner sound. And because amps are built into loudspeaker cabinets, there’s no need for long lengths of connecting cable, which can become prone to distortion and signal loss.

Tighter transients: Since self-powered loudspeakers have very short internal cables, amps inside can more effectively dampen driver mechanical motion, which leads to better sonic accuracy and tighter, crisper transients. (And, there’s none of the loss in levels and signal quality inherent over long cable distances.)

Certified Safe: Nothing matters more than the safety of your staff and customers. Because self-powered loudspeakers incorporate amplification, they must undergo rigorous testing by Underwriters Laboratories and other international organizations to ensure they operate safely and guard against the risk of fire, electric shock, and inadequate structural design. Enjoy peace of mind knowing Meyer Sound powered products are certified by FCC, UL, CSA, CE, and CEE   the most stringent agencies in the business.

The Problems with Passive

What about passive loudspeakers? At first glance, passive systems may seem like a bargain. But we already know that passive systems require more components and accessories than powered systems. Sonically, they exhibit potential for signal loss over distances, and it is very hard to ensure consistent, optimal sound and volume as amplifiers have many variables to consider when being matched to loudspeakers, such as cable lengths and gauge as well as the number of speakers connected to the amplifier.

Passive systems are often touted as easy to service. But because powered loudspeakers are so complex to design and build, self-powered loudspeakers usually represent the top innovations from leading manufacturers   better quality translates to better reliability, which means fewer maintenance issues in the long run.

At face value, passive systems might seem less expensive and easier to maintain. But once you start adding in amps, cables, and other components   not to mention increased transport and labor costs   you’ll find that those savings just don’t add up to a better value.

Step Up to a Self-Powered System

Once you recognize all of the advantages inherent in self-powered loudspeaker systems, it’s easy to understand why the world’s top venues and productions rely on them to deliver consistently stunning sound.
