Meyer Sound LEO M, 1100-LFC, and Galaxy Overview

1. Meyer Sound LEO M

1.1 What It Is

The LEO M is a self-powered linear line-array loudspeaker designed for large-scale sound reinforcement in arenas, stadiums, and tours. It delivers extremely high output with clarity and linearity, making it ideal for long-throw applications.

1.2 Key Specifications

• Frequency Range: ~55 Hz – 16 kHz

• Peak Output (SPL): Up to 149.5 dB (M-noise, referenced to 1 m)

• Amplification: 3-channel MOSFET (class AB/H bridged)

• Dimensions: 44.4 in (W) × 17.8 in (H) × 23 in (D)

• Weight: ~265 lb (120 kg)

• Rigging: Integrated “GuideALinks” system for adjustable splay angles

1.3 Usage

• Forms the main mid/high array in a concert system

• Often paired with downfill elements for near-field coverage

• Typically used alongside 1100-LFC units for low-frequency reinforcement

2. Meyer Sound 1100-LFC

2.1 What It Is

The 1100-LFC is a self-powered low-frequency control element (subwoofer). It extends system response down to 28 Hz and provides powerful, linear low-end energy for large venues.

2.2 Key Specifications

• Operating Range: 28 Hz – 100 Hz

• Frequency Response: 30 Hz – 85 Hz (±4 dB, half-space)

• Peak Output (SPL): ~140 dB

• Drivers: Two 18-inch long-excursion cone drivers

• Amplification: 2-channel MOSFET (class AB/H bridged)

• Power: Continuous ~10.5 A rms (230 V) / Burst ~18 A rms

• Dimensions: 52.6 in (W) × 20.5 in (H) × 33 in (D)

• Weight: ~249 lb (113 kg)

• Rigging Options: Flyable, stackable, cardioid configurations

2.3 Usage

• Provides sub-bass extension for line arrays like LEO M

• Can be flown or ground-stacked

• Often used in cardioid arrays to control bass directionality and reduce unwanted stage bleed

• Features TruPower limiting and remote monitoring for reliability

3. Meyer Sound Galaxy (Galileo / GALAXY Network Platform)

3.1 What It Is

The GALAXY Network Platform (previously known as Galileo / Callisto) is Meyer Sound’s digital matrix and control system. It provides signal routing, delay, EQ, and system integration for Meyer’s self-powered loudspeakers.

3.2 Core Functions

• Audio Routing / Matrixing: Distributes signals across multiple arrays or zones

• Time Alignment: Ensures all speakers (LEO, subs, fills) remain phase-coherent

• Processing: Parametric EQ, filters, crossovers, and shaping for different speaker models

• Monitoring: Works with RMS for real-time diagnostics

• System Integration: Manages hundreds of loudspeakers in large touring or fixed installations

3.3 Usage

• Sits at the center of the system, managing LEO M arrays and 1100-LFC subs

• Provides crossover management (e.g., LEO handing off around 100 Hz to the 1100-LFC)

• Handles gain structure, delay alignment, and EQ for consistent coverage

4. How They Work Together

A full Meyer Sound system often looks like this:

1. LEO M modules are flown as the main array for mid and high frequencies.

2. 1100-LFCs provide sub-bass reinforcement, flown or ground-stacked in various configurations.

3. Galaxy platform controls, routes, delays, and equalizes signals for all components.

4. System alignment is performed so that subs and arrays blend smoothly, with precise phase and timing.

5. Rigging and prediction software (like MAPP) ensure correct coverage and SPL distribution.

✅ In short:

• LEO M = long-throw, high-output line array (mids/highs)

• 1100-LFC = powerful low-frequency control element (subs)

• Galaxy = the brain of the system, managing processing, routing, and integration
