LEO-M LINEAR LINE ARRAY LOUDSPEAKER

The LEO-M™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.

To guarantee optimum performance, LEO array systems

should be designed with Meyer Sound’s MAPP™prediction

software. The intuitive, cross-platform application accurately

predicts coverage patterns, frequency and impulse

responses, and maximum peak SPL for LEO array systems,

ensuring that systems deliver the required SPL and ideal

coverage for the intended audience areas.

LEO-M’s high-frequency section is comprised of two propri-

etary compression drivers coupled to a constant-directivity

horn through a patented REM®manifold. The manifold’s

smooth radiating characteristics afford tight vertical cover-

age. The low-frequency section includes two long-excursion

cone drivers, also proprietary, capable of withstanding high,

continuous output levels. Precise phase and magnitude

alignment between low- and high-frequency drivers yields

consistent and well-behaved system responses.

The unit’s onboard power amplifier operates at nominal volt-

ages from 165–264 V AC at 50–60 Hz. TruPower®limiting

ensures maximum driver protection, minimizing power com-

pression while yielding high constant output under high con-

tinuous and peak power conditions. The amplifier, control

electronics, and power supply are contained in a single field-

replaceable module located on the rear of the cabinet.

Meyer Sound’s RMS™remote monitoring system comes

standard with all LEO-M loudspeakers and provides com-

prehensive monitoring of system parameters on a Mac®or

Windows®-based computer. Convenient XLR 5-pin connec-

tors allow the use of composite cables carrying both RMS

and balanced audio signals.

LEO-M Loudspeaker

CHAPTER 1: INTRODUCTION

LEO-M offers intuitive rigging with captive GuideALinks™

that can be set to the desired splay angles while cabinets

rest in caster frames. The MTG-LEO-M top grid flies arrays

of up to 18 LEO-Ms at a 7:1 safety factor (with some restric-

tions). Optional transition frames are available for flying

LYONs or MICAs below LEO-M arrays for downfill. Stacks of

up to four LEO-Ms can be securely transported with the

optional MCF-LEO-M caster frame; durable nylon covers,

accommodating stacks of two, three, or four units, are avail-

able to protect the cabinets during transport.

The vented LEO-M cabinet is constructed of multi-ply hard-

wood and coated with a black-textured finish. A hex-

stamped, steel grille with acoustical black mesh protects the

unit’s drivers. The cabinet is weather protected and includes

a collapsible rain hood that shields user panel connectors

from water intrusion.

CHAPTER 2: POWER REQUIREMENTS

LEO-M combines advanced loudspeaker technology with

equally advanced power capabilities. Understanding power

distribution, voltage and current requirements, and electrical

safety guidelines is critical to the safe operation of LEO-M.

AC POWER DISTRIBUTION

All components in an audio system (self-powered loud-

speakers, mixing consoles, and processors) must be prop-

erly connected to an AC power distribution system, ensuring

that AC line polarity is preserved and that all grounding

points are connected to a single node or common point

using the same cable gauge (or larger) as the neutral and

line cables.

CAUTION: Make sure the voltage received by

LEO-M remains within its 165–264 V AC oper-

ating range. In addition, the ground line must always

be used for safety reasons and the line-to-ground

voltage should never exceed 250 V AC (typically

120 V AC from line to ground).

CAUTION: Before applying AC power to any

Meyer Sound self-powered loudspeaker, make

sure that the voltage potential difference between the

neutral and earth-ground lines is less than 5 V AC

when using single-phase AC wiring.

NOTE: Improper grounding of connections

between loudspeakers and the rest of the

audio system may produce noise or hum, or cause

serious damage to the input and output stages of the

system’s electronic components.

120 V AC, 3-Phase Wye System (Two Lines)

Line-Line-Earth/Ground

Figure 1 illustrates a 120 V AC, 3-phase Wye distribution

system with each loudspeaker connected to two lines and a

common earth/ground line. This configuration is possible

because LEO-M tolerates elevated voltages from the ground

line and does not require a neutral line. This system delivers

208 V AC to each loudspeaker.

TIP: The 120 V AC, 3-phase Wye system with

two lines is recommended because it allows

loudspeakers to draw less current than with single-

line systems, thereby reducing voltage drop due to

cable resistance.

220 V AC, 3-Phase Wye System (Single Line)

Line-Neutral-Earth/Ground

Figure 2 illustrates a basic 220 V AC, 3-phase Wye distribu-

tion system with the loudspeaker load distributed across all

three phases, with each loudspeaker connected to a single

line and common neutral and earth/ground lines. This sys-

tem delivers 220 V AC to each loudspeaker.

CAUTION: For 220 V AC, 3-phase Wye sys-

tems, never connect two lines to the AC input

of LEO-M, as the resulting voltage would be higher

than the allowable upper voltage range (275 V AC)

and would damage the loudspeaker.

CHAPTER 2: POWER REQUIREMENTS

AC INPUT

The LEO-M user panel includes an AC Input connector that

supplies power to the loudspeaker. The 3-conductor

powerCON 32 is rated at 32 A and uses a locking connector

that prevents accidental disconnections.

LEO-M ships with a black powerCON 32 cable mount con-

nector, rated at 32 A, for assembling AC power cables.

Make sure to use an AC power cable that is wired correctly

(see “Wiring AC Power Cables” on page 8) and equipped

with the appropriate power plug (on the other end) for the

area in which you will operate the unit.

LEO-M requires a grounded outlet. To operate safely and

effectively, it is extremely important that the entire system be

properly grounded.

WIRING AC POWER CABLES

LEO-M ships with a black powerCON 32 cable mount con-

nector, rated at 32 A, for assembling AC power cables. The

pins on the powerCON 32 cable mount connector are

labeled as follows:

■L (Line)

■N (Neutral)

■PE (Protective Earth or Ground)

How AC power cables are wired is determined by the type of

AC power distribution system used (see “AC Power Distri-

bution” on page 7). When wiring AC power cables for single-

line systems, use one of the following wiring schemes:

CAUTION: When wiring AC power cables and

distribution systems, it is important to preserve

AC line polarity and connect the earth ground on both

ends of the cable. LEO-M requires a grounded con-

nection. Always use a grounded outlet and plug. It is

extremely important that the system be properly

grounded to operate safely and properly. Do not

ground-lift the AC cable.

LEO-M OPERATING INSTRUCTIONS

Supported Cable Gauges for the powerCON 32

While the powerCON 32 connector supports cable gauges

of 14–10 AWG (2.5–6.0 mm2), due to LEO-M’s current draw,

10 AWG (6.0 mm2) should be used whenever possible.

LEO-M VOLTAGE REQUIREMENTS

CAUTION: Due to its expanded power capabil-

ities, LEO-M was engineered to operate only at

220 V AC (208–235 V AC) to reduce current draw.

Make sure to use AC power cables with sufficient

gauge to operate with stable voltages during peaks

and that the AC power source is capable of providing

enough power.

LEO-M operates as intended when receiving AC voltage

within the following range:

■165–264 V AC, 50–60 Hz

If the voltage drops below 165 V, the loudspeaker uses

stored power to continue operating temporarily; the loud-

speaker powers off if the voltage does not return to its oper-

ating range.

If the voltage rises above 275 V, the power supply could

become damaged.

CAUTION: To ensure that LEO-M performs as

specified, without interruption, and without

damage to its power supply:

1. Its power source must operate within the required

voltage window (208–235 V AC).

2. Its AC cable length and gauge must be such that

peak voltage drops do not exceed 5 percent of its

voltage.

NOTE: When voltage fluctuates within the

loudspeaker’s operating ranges, automatic tap

selection stabilizes the voltage. Tap selection is

instantaneous with no audible artifacts, allowing con-

tinuous operation.

LEO-M CURRENT REQUIREMENTS

Current draw for loudspeakers is dynamic and fluctuates as

operating levels change. Since different cables and circuit

breakers heat up at varying rates, it is important to under-

stand the following types of current ratings and how they

affect circuit breaker and cable specifications.

■Idle Current — The maximum rms current during idle

periods.

■Maximum Long-Term Continuous Current — The

maximum rms current during a period of at least

10 seconds. The maximum long-term continuous current

is used to calculate temperature increases for cables, to

ensure that cable sizes and gauges conform to electrical

code standards. The current rating is also used as a rat-

ing for slow-reacting thermal breakers, which are recom-

mended for loudspeaker power distribution.

■Burst Current — The maximum rms current during a

period of around 1 second. The burst current is used as

a rating for magnetic breakers. It is also used for calcu-

lating the peak voltage drop in long AC cable runs

according to the following formula:

V pk (drop) = I pk x R (cable total)

■Maximum Instantaneous Peak Current — A rating for

fast-reacting magnetic breakers.

■Inrush Current — The spike of initial current encoun-

tered when powering on.

You can the following table as a guide for selecting cable

gauges and circuit breaker ratings for the system’s operat-

ing voltage.

The minimum electrical service amperage required by a

loudspeaker system is the sum of the maximum long-term

continuous current for all loudspeakers. An additional

30 percent above the minimum amperage is recommended

to prevent peak voltage drops at the service entry.

CHAPTER 2: POWER REQUIREMENTS

NOTE: For best performance, the AC cable volt-

age drop should not exceed 10 V (5 percent at

230 V). Make sure that even with AC voltage drops that

the voltage always remains within the loudspeaker’s

operating range.

DO NOT RESET CIRCUIT BREAKERS!

CAUTION: In the unlikely event that one of

LEO-M’s circuit breakers trips (the center but-

ton disengages), disconnect the AC power cable and

contact Meyer Sound for repair information. DO NOT

attempt to reset the breaker or reconnect the AC

power cable.

INTELLIGENT AC POWER SUPPLY

LEO-M’s Intelligent AC™ power supply eliminates high

inrush currents with soft-start power up; suppresses high-

voltage transients up to several kilovolts; filters common

mode and differential mode radio frequencies (EMI); and

sustains operation temporarily during low-voltage periods.

Powering on LEO-M

When powering on LEO-M, the following startup events take

place over several seconds.

1. Audio output is muted.

2. The primary fan turns on.

3. The power supply ramps up.

4. On the user panel, the Active LED turns solid green, indi-

cating the loudspeaker is ready to output audio.

CAUTION: If the Active LED does not turn solid

green, or LEO-M does not output audio after

10 seconds, remove AC power immediately and ver-

ify that the voltage is within the required range. If the

problem persists, contact Meyer Sound Technical

Support.

ELECTRICAL SAFETY GUIDELINES

Make sure to observe the following important electrical and

safety guidelines.

■The powerCON 32 connector should not be engaged or

disengaged when under load or live.

■LEO-M requires a grounded outlet. Always use a

grounded outlet and plug.

■Do not use a ground-lifting adapter or cut the AC cable

ground pin.

■Make sure the AC power cable for the loudspeaker has the

appropriate power plug (on the other end) for the area in

which you will operate the loudspeaker.

■Do not operate the unit if the power cable is frayed or

broken.

■Keep all liquids away from LEO-M loudspeakers to avoid

hazards from electrical shock.

■Use the cable rings (see “Cable Rings” on page 12) on

the rear of the LEO-M cabinet to reduce strain on the AC

power cable (and audio cables). Do not use the cable

rings for any other purpose.
