LYON LINEAR LINE ARRAY LOUDSPEAKER

The self-powered LYON™ linear line array loudspeaker

(Figure 1) is a member of Meyer Sound’s LEO

linear loudspeakers, designed to reproduce audio faithfully

with tremendous power and clarity, without coloring the

sound, even when pushed to the limit. LYON delivers the

same headroom and precision as the acclaimed

LEO-M

™

—with the same cutting-edge technology housed in

a lighter and more compact cabinet. Optimized rigging and

self-powered configuration streamline both setup and

breakdown for LYON systems. LYON is ideal for medium- to

large-scale array applications that do not require the extreme

long-throw capability of LEO-M.

Figure 1: LYON Loudspeaker

For greater flexibility, LYON is available in three models:

LYON-M for primary array coverage, LYON-W for wide

coverage, and LYON-WXT for wide coverage with extended

vertical coverage. LYON-W can be used wherever wide

coverage is needed in LYON arrays, at the bottom or in the

middle of primary arrays, or even at the top of outfill arrays.

Because LYON-W matches the acoustical characteristics

and vertical coverage of LYON-M, transitions for horizontal

coverage are seamless. LYON models are matched

acoustically to LEO-M and can be used for downfill and

midfill at the bottom of LEO-M arrays, and as supplemental

sidefill and outfill arrays in LEO-M systems.

LYON arrays are ideally paired with Meyer Sound’s

1100-LFC low-frequency control element for bass

reproduction. Entire systems are driven by Meyer Sound’s

Galileo GALAXY Network Processor, which provides matrix

routing, alignment, and processing for array components. To

guarantee optimum performance, including coverage

patterns and maximum peak SPL, LYON systems should be

designed with Meyer Sound’s MAPP

™

prediction software.

LYON’s high-frequency section comprises two proprietary

compression drivers coupled to a constant-directivity horn

LYON OPERATING INSTRUCTIONS

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

radiating characteristics afford tight vertical coverage. 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

voltages from 85–134 V AC and 165–264 V AC at 50–60 Hz.

TruPower

limiting ensures maximum driver protection,

minimizing power compression while yielding high constant

output under high continuous 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 LYON loudspeakers and provides

comprehensive monitoring of system parameters on a Mac

or Windows

-based computer. Convenient XLR 5-pin

connectors allow the use of composite cables carrying both

RMS and balanced audio signals. XLR 3-pin audio

connectors are also available.

LYON offers intuitive rigging with captive GuideALinks

™

that

can be set to the desired splay angles while cabinets rest in

caster frames. The optional MTG-LYON top grid (Figure 2)

flies arrays of up to 22 LYONs at a 5:1 safety factor (with

some restrictions—always use MAPP to verify load ratings).

The optional MTF-LEO/LYON transition frame flies LYONs at

the bottom of LEO-M arrays. Stacks of up to four LYON

cabinets can be securely transported with the optional

MCF-LYON caster frame; durable nylon covers,

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

available to protect the cabinets during transport.

The LYON cabinet is constructed of premium multi-ply birch

and coated with a slightly textured black finish. A powder-

coated, hex-stamped, steel grille with acoustical black mesh

protects the unit’s drivers. Other options include weather

protection and custom color finishes for fixed installations

and applications with specific cosmetic requirements.

LYON 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 LYON.

AC POWER DISTRIBUTION

All components in an audio system (self-powered

loudspeakers, mixing consoles, and processors) must be

properly 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

LYON remains within its 85–134 V AC and

165–264 V AC operating ranges. 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).

Figure 3: 120 V AC, 3-Phase Wye System (Single Line to Loudspeakers)

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

Line-Line-Earth/Ground

Figure 4 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 LYON tolerates elevated voltages from the ground

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

208 V AC to each loudspeaker.

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 (Single Line)

Line-Neutral-Earth/Ground

Figure 3 illustrates a basic 120 V AC, 3-phase Wye

distribution 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

system delivers 120 V AC to each loudspeaker.

Figure 4: 120 V AC, 3-Phase Wye System (Two Lines to Loudspeakers)

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. It also excludes the potential of

varying ground to neutral voltages producing an audi-

ble hum.

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

Line-Neutral-Earth/Ground

Figure 5 illustrates a basic 230 V AC, 3-phase Wye

distribution system with the loudspeaker load distributed

a single line and common neutral and earth/ground lines. This

system delivers 230 V AC to each loudspeaker.

the upper voltage limit (275 V AC) and will damage

the loudspeaker.

WIRING AC POWER CABLES

LYON ships with a black powerCON 32 cable mount

connector (Figure 7), 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)

AC INPUT

The LYON user panel includes an AC Input connector that

supplies power to the loudspeaker. The 3-conductor

PowerCON 32 (Figure 6) is rated at 32 A and uses a locking

connector that prevents accidental disconnections.

Figure 6: PowerCON 32 AC Input Connector

LYON ships with a black powerCON 32 cable mount

connector, 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 12) and equipped

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

in which you will operate the unit.

LYON requires a grounded outlet. To operate safely and

effectively, it is extremely important that the entire system be

properly grounded.

Figure 7: PowerCON 32 Cable Mount Connector

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

AC power distribution system used (see “AC Power

Distribution” on page 11). When wiring AC power cables for

single-line systems, use one of the wiring schemes described

in Table 1 and illustrated in Figure 8:

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. LYON requires a grounded

connection. 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.

CHAPTER 2: POWER REQUIREMENTS

Supported PowerCON 32 Cable Gauges

While the powerCON 32 connector supports cable gauges of

14–10 AWG (2.5–6.0 mm

10 AWG (6.0 mm

), because of LYON’s current draw,

) should be used whenever possible.

LYON VOLTAGE REQUIREMENTS

LYON operates as intended when receiving AC voltage within

the following ranges:

•85–134 V AC, 50–60 Hz

•165–264 V AC, 50–60 Hz

If the voltage drops below 85V, the loudspeaker uses stored

power to continue operating temporarily; the loudspeaker

powers off if the voltage does not return to its operating range.

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

become damaged.

CAUTION: The power source for LYON should

always operate within the required operating

range, at least a few volts from the upper and lower

limits. This ensures that AC voltage variations from the

service entry—or peak voltage drops due to cable

runs—will not cause the loudspeaker’s amplifier to

cycle on and off or cause damage to the power supply.

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.

Use the information provided in Table 2 as a guide for

selecting the gauge of cables and the circuit breaker ratings

for the system’s operating 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 combined Maximum Long-Term

Continuous amperages is recommended to prevent peak

voltage drops at the service entry.

LYON CURRENT REQUIREMENTS

Current draw for loudspeakers is dynamic and fluctuates as

operating levels change. Because different cables and circuit

breakers heat up at varying rates, it is important to understand

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 the size and gauge of the cables conform to

electrical code standards. The current rating is also used

to select appropriately rated, slow-reacting thermal

breakers, which are recommended 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:

NOTE: For best performance, the AC cable volt-

age drop should not exceed 10 V (10percent at

115 V and 5 percent at 230 V). This ensures that the

AC voltage variations from the service entry—or peak

voltage drops due to longer cable runs—do not cause

the amplifier to cycle on and off.

DO NOT RESET CIRCUIT BREAKERS!

CAUTION: In the unlikely event that one of

LYON’s circuit breakers trips (the center button

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

LYON’s Intelligent AC™ power supply automatically selects

the correct operating voltage (allowing the loudspeaker to be

used internationally without manually setting voltage

switches), eliminates high inrush currents with soft-start

power up, suppresses high-voltage transients up to several

kilovolts, filters common mode and differential mode radio

LYON OPERATING INSTRUCTIONS

frequencies (EMI), and sustains operation temporarily during

low-voltage periods.

Powering on LYON

When powering on LYON, the following startup events take

place over several seconds.

1.Audio output is muted.

2.Voltage is detected and the power supply mode is auto-

matically adjusted as necessary.

3.The primary fan turns on.

4.The power supply ramps up.

5.On the user panel, the Active/Status LED flashes multiple

colors successively.

6.The Active/Status LED turns solid green, indicating the

loudspeaker is already unmuted and ready to output

audio.

CAUTION: If the Active/Status LED does not

turn solid green, or LYON does not output

audio after 10 seconds, remove AC power

immediately and verify that the voltage is within the

required range. If the problem persists, contact

Meyer Sound Technical Support.

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

rings for any other purpose.

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 energized. Either de-

energize or disconnect the other end of the cable.

•LYON 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 loudspeaker if the power cable is

frayed or broken.

•Keep all liquids away from LYON loudspeakers to avoid

hazards from electrical shock.

•Use the cable rings (see “Cable Rings” on page 16) on

the rear of the LYON cabinet to reduce strain on the AC

CHAPTER 3: AMPLIFICATION AND AUDIO

LYON’s drivers are powered by a proprietary three-channel

amplifier with bridged MOSFET output stages. The audio

signal is processed with an electronic crossover plus

correction filters for flat phase and frequency responses, and

by driver protection circuitry. Each channel has peak and rms

limiters that prevent driver over-excursion and regulate voice

coil temperatures.

The LYON user panel (Figure 9) includes Input and Loop

output connectors for audio, Limit and Active LEDs, and RMS

connectors and controls (see Chapter 5, “RMS Remote

Monitoring System”).

AUDIO CONNECTORS

LYON is available with XLR 3-pin or 5-pin connectors for

audio Input and audio Loop output (Figure 10 and Figure 11).

XLR 5-pin connectors accommodate both balanced audio

and RMS signals.

Figure 10: XLR 5-Pin Audio Connectors, Input and Loop Output

Figure 9: LYON User Panel

Figure 11: XLR 3-Pin Audio Connectors, Input and Loop Output

Audio Input (XLR 3-Pin or 5-Pin Female)

The XLR 3-pin or 5-pin female Input connector accepts

balanced audio signals with an input impedance of 10 kOhm.

The connector uses the following wiring scheme:

•Pin 1 — 1 kOhm to chassis and earth ground (ESD

clamped)

•Pin 2 — Signal (+)

•Pin 3 — Signal (–)

•Pin 4 — RMS (polarity insensitive)

•Pin 5 — RMS (polarity insensitive)

•Case — Earth (AC) ground and chassis

NOTE: Pins 4 and 5 (RMS) are included only

with XLR 5-pin connectors.

LYON OPERATING INSTRUCTIONS

Pins 2 and 3 carry the input as a differential signal. Pin 1 is

connected to earth through a 1 kOhm, 1000 pF, 15 V

clamped network. This circuitry provides virtual ground lift for

audio frequencies while allowing unwanted signals to bleed to

ground. Make sure to use balanced XLR audio cables with

pins 1–3 connected on both ends. Telescopic grounding is

not recommended and shorting an input connector pin to the

case may cause a ground loop, resulting in hum.

TIP: If unwanted noise or hiss is produced by the

loudspeaker, disconnect its input cable. If the

noise stops, there is most likely nothing wrong with the

loudspeaker. To locate the source of the noise, check

the audio cable, source audio, AC power, and electri-

cal ground.

Audio Loop Output (XLR 3-Pin or 5-Pin Male)

The XLR 3-pin or 5-pin male Loop output connector allows

multiple loudspeakers to be looped from a single audio

source. The Loop output connector uses the same wiring

scheme as the Input connector (see “Audio Input (XLR 3-Pin

or 5-Pin Female)” on page 15). For applications that require

multiple LYONs, connect the Loop output of the first

loudspeaker to the Input of the second loudspeaker, and so

forth.

NOTE: Most source devices are capable of

driving loads no less than 10 times their output

impedance.

TIP: Audio outputs from Meyer Sound’s

Galileo GALAXY Network Platform have an out-

put impedance of 50 ohms. Each output can drive up

to 20 Meyer Sound (10 kOhm) loudspeakers without

distortion.

CAUTION: Make sure that all cabling for

looped loudspeakers is wired correctly (Pin 1

to Pin 1, Pin 2 to Pin 2, and so forth) to prevent the

polarity from being reversed. If one or more

loudspeakers in a system have reversed polarity,

frequency response and coverage will be significantly

degraded.

CABLE RINGS

Two cable rings are provided on the rear of the LYON cabinet

(Figure 12). Power and audio cables should be tied off to the

rings to reduce strain on the cables and prevent damage to

them during installation. The cable rings should not be used

for any other purpose.

NOTE: The Loop output connector is wired in

parallel to the Input connector and transmits

the unbuffered source signal even when the loud-

speaker is powered off.

Calculating Load Impedance for Looped Audio

Signals

To avoid distortion when looping multiple loudspeakers,

make sure the source device can drive the total load

impedance of the looped loudspeakers. In addition, the

source device must be capable of delivering approximately

20 dBV (10 V rms into 600 ohms) to yield the maximum SPL

over the operating bandwidth of the loudspeakers.

To calculate the load impedance for the looped

loudspeakers, divide 10 kOhms (the input impedance for a

single loudspeaker) by the number of looped loudspeakers.

For example, the load impedance for ten LYONs is

1000 ohms (10 kOhms / 10). To drive this number of looped

loudspeakers, the source device should have an output

impedance of 100 ohms or less. This same rule applies when

looping LYONs with other Meyer Sound self-powered

loudspeakers.

Figure 12: Cables Tied Off to Cable Ring

CAUTION: LYON cable rings should only be

used to reduce strain on cables. The cable

rings should not be used for any other purpose.

TRUPOWER LIMITING

LYON employs Meyer Sound’s advanced TruPower® limiting.

Conventional limiters assume a constant loudspeaker

impedance and set the limiting threshold by measuring

voltage alone. This method is inaccurate because

loudspeaker impedances change as frequency content in the

CHAPTER 3: AMPLIFICATION AND AUDIO

source material changes, and as thermal values for the

loudspeaker’s voice coil and magnet vary. Consequently,

conventional limiters often begin limiting prematurely, which

reduces system headroom and dynamic range.

In contrast, TruPower limiting anticipates varying

loudspeaker impedances by measuring both current and

voltage to compute the actual power dissipation in the voice

coil. This approach improves performance, both before and

during limiting, by allowing the driver to produce the

maximum SPL across its entire frequency range, while also

retaining signal peaks. TruPower limiting also eliminates

power compression at high levels over lengthy periods, which

helps regulate voice coil temperatures, thereby extending the

life of the driver.

HF and LF Limit LEDs

The low- and high-frequency drivers for LYON are powered

by separate amplifier channels, each with their own limiter.

Limiting activity is indicated with two Limit LEDs on the user

panel (Figure 13). The HF Limit LED indicates limiting for the

high-frequency channel and the LF Limit LED indicates

limiting for the low-frequency channel.

Figure 13: LYON Limit LEDs

When engaged, the limiters not only protect the drivers but

also prevent signal peaks from causing excessive distortion in

the amplifier channels, thereby preserving headroom and

maintaining smooth frequency response at high levels. When

levels return to normal, below the limiter thresholds, limiting

ceases.

LYON performs within its acoustical specifications at normal

temperatures when the Limit LEDs are unlit, or when the LEDs

are lit for 2 seconds or less and then turn off for at least

1 second. If the LEDs remain lit for longer than 3seconds, the

loudspeaker enters hard limiting where:

•Increases to the input level have no effect

•Distortion increases due to clipping

•Drivers are subjected to excessive heat and excursion,

thereby compromising their lifespan

CAUTION: The Limit LEDs indicate when a

safe, optimum level is exceeded. If a LYON

loudspeaker system begins to limit before reaching

the desired SPL, consider adding more loudspeakers

to the system.

AMPLIFIER COOLING SYSTEM

LYON employs forced-air cooling with four ultra high-speed

fans (two primary, and two reserve) to prevent the amplifier

from overheating (see Table 3 for details). The fans draw air in

through ducts on the rear of the cabinet, over the heat sinks,

and out the rear of the cabinet. Because dust does not

accumulate in the amplifier and power circuitry, their lifespans

are increased significantly.

CAUTION: To keep LYON from overheating,

allow at least 6 inches behind the cabinet for

proper ventilation.

CHAPTER 4: QUICKFLY RIGGING

IMPORTANT SAFETY CONSIDERATIONS!

When installing Meyer Sound loudspeakers and subwoofers, the following precautions should always be observed:

•All Meyer Sound products must be used in accordance

with local, state, federal, and industry regulations. It is

the owner’s and user’s responsibility to evaluate the reli-

ability of any rigging method for their application. Rigging

should only be carried out by experienced professionals.

•Use mounting and rigging hardware that has been rated

to meet or exceed the weight being hung.

•Make sure to attach mounting hardware to the building’s

structural components (roof truss), and not just to the

wall surface.

•Make sure bolts and eye bolts are tightened securely.

Meyer Sound recommends using Loctite

on all

threaded fasteners.

•Inspect mounting and rigging hardware regularly. Imme-

diately replace any worn or damaged components.

LYON RIGGING OPTIONS

LYON OPERATING INSTRUCTIONS

LYON GUIDEALINKS

LYON is equipped with four captive GuideALinks and four

mating link slots that link to adjacent units in flown arrays.

Located at the top corners of the cabinet, GuideALinks

extend up and into the link slots of the cabinet above it, or into

the link slots of the MTG-LYON grid, making it easy to link

cabinets once they are stacked (Figure 14 and Figure15).

GuideALinks extend and retract with knobs and are secured

with two quick-release pins: one each in the top and bottom

cabinets. Each LYON loudspeaker ships with 10

7/16 x 0.90-inch quick-release pins (black button)

(PN 134.050).

positions. Rear GuideALinks can be pinned in either of two

positions: extended or stowed.

Figure 14: LYON GuideALinks with Quick-Release Pins, Exploded View

CAUTION: GuideALinks must be secured with

the included quick-release pins. At no time

should the weight of the loudspeaker rest on the

GuideALink knobs when the links are fully extended

(without the pins inserted). GuideALink knobs are for

extending and retracting the links only.

LYON Splay Angles

Rear GuideALinks attach at a fixed splay angle of 0 degrees

and act as a pivot point between linked LYONs, with the splay

angle between the units determined by the front GuideALink

Figure 15: LYON GuideALinks (Exposed) Attached at 0 Degrees

Front GuideALinks determine the loudspeaker splay angles

and are configured with the yellow ANGLE positions when the

cabinets are resting in the caster frame (Figure 16). After the

stack is lifted with the motors, the loudspeakers rotate on the

axis of the rear GuideALinks and the front GuideALinks slide

into position as the weight of the loudspeakers causes the

cabinets to shift, at which point, quick-release pins are

inserted in the corresponding blue LOCKING positions to lock

the splay angles.

Available splay angles for linked LYONs include 0.0, 0.5, 1.0,

1.5, 2.0, 3.0, 4.0, 5.0, 7.0, and 9.0 degrees and are indicated

by the blue and yellow GuideALink labels.

CAUTION: Splay angles of 0 degrees should

only be used for the top cabinet attached to

the grid. Splay angles of at least 0.5 degrees are

recommended for cabinets near the top of the array.

If multiple cabinets are set to 0 degrees and the array

is flown with downtilt, the resulting splay angles could

be negative because of the gaps in the links and pins

that facilitate easy pinning.

CHAPTER 4: QUICKFLY RIGGING

NOTE: The splay angles listed on the

GuideALink labels are for relative angles

between the center axes of the linked units. For

example, setting the GuideALinks to 5 degrees yields

a 5-degree downtilt of the lower unit to the upper unit.

How the loudspeakers relate to the floor, stage, and

seating angles in the venue depends on the orientation

of the grid, the angles of the loudspeakers in the array

above them, and other factors. MAPP prediction

software should be used to calculate optimum splay

angles for loudspeakers and to predict coverage

patterns for arrays.

Angle (Yellow)

Sets splay angles for

WHEN TO MOVE THE LOCKING PINS TO THE

“STOW PIN” POSITION

The quick-release pins in the blue LOCKING positions must

be moved to the STOW PIN position before either lifting or

lowering an array. The removal of the quick-release pins from

the LOCKING positions allows the splay angles to expand and

contract when assembling and disassembling the array.

Moving the pins to the STOW PIN position also keeps them

handy so they won’t be dropped or misplaced.

TIP: Resist the urge to put the blue locking pins

in your pocket. Instead place them in the STOW

PIN position before lifting or lowering the array.

LYON OPERATING INSTRUCTIONS

CHAPTER 5: RMS REMOTE MONITORING SYSTEM

LYON includes an RMS remote monitoring system module,

allowing the loudspeaker to be connected to an RMS

network. RMS reports, in real time, the status and power

usage of multiple Meyer Sound loudspeakers from a Mac

Windows

-based computer. The RMServer™ communicates

with Meyer Sound loudspeakers equipped with RMS

™

modules. RMServer

a compact, Ethernet-based hardware

unit with two FT-10 RMS data ports. RMServer stores system

configurations internally, eliminating most manual data entry.

Systems can be monitored from a computer at front-of-house

or backstage, or from a laptop anywhere within the venue over

WiFi.

NOTE: For the latest RMS system require-

ments, visit the Meyer Sound website

(

http://www.meyersound.com

NOTE: RMS does not control AC power.

COMPASS RMS SOFTWARE

Compass RMS™ software provides extensive system status

and performance data for each loudspeaker, including

amplifier voltage, limiting activity, power output, fan and

driver status, as well as mute and solo capability.

Loudspeakers are added to the RMS network and assigned

a node name during a one-time discovery procedure. After

loudspeakers are identified on the RMS network, they appear

in Compass RMS as icons that can be customized to suit your

needs (Figure 17).

Individual loudspeakers can be physically identified with the

Wink option in RMS, which lights the Wink LED on the RMS

module of that particular loudspeaker. Conversely, a

loudspeaker can be identified in Compass RMS by pressing

the Identify button on the loudspeaker’s RMS module.

Loudspeaker icons can be arranged in Compass RMS and

saved as pages to represent how the loudspeakers have been

deployed in the system. Multiple pages can be saved and

recalled for specific performances and venues.

RMS MODULE

The LYON RMS user panel includes an Identify button,

Remote Mute switch, Wink/Activity LED, and two Network

connectors (Figure 18).

Figure 18: LYON RMS Module

NOTE: The Identify button and Wink/Activity

LED on the RMS user panel are used exclu-

sively by RMS and have no effect on the acoustical or

electrical activity of the loudspeaker.

Figure 17: Compass RMS Window

Identify Button

The Identify button serves the following functions:

•If the loudspeaker has not yet been discovered on the

RMS network (Wink/Activity LED not lit), press the Iden-

tify button to discover it.

•To remove the loudspeaker from the RMS network,

press and hold the Identify button during startup (see

“Resetting the RMS Module” on page 26).

•To wink a discovered loudspeaker, press the Identify

button. The Wink LED on the loudspeaker icon in Com-

pass RMS lights up and the Wink/Activity LED on the

loudspeaker’s RMS user panel turns solid green. Press

the Identify button again to unwink the loudspeaker.

TIP: The Wink function is useful for identifying

the physical loudspeaker corresponding to a

loudspeaker icon in Compass RMS.

LYON OPERATING INSTRUCTIONS

Wink/Activity LED (Green)

The green Wink/Activity LED indicates the status of the

loudspeaker:

•During startup, the LED flashes green 10 times.

•If the loudspeaker has not yet been discovered on the

RMS network, the LED is not lit after startup.

•If the loudspeaker has been successfully discovered on

the RMS network, the LED flashes green continuously

and flashes more rapidly with increased data activity.

•When the loudspeaker is winked, either by clicking the

Wink button in Compass RMS or by pressing the Identify

button on the RMS user panel, the LED is solid green.

The LED remains solid green until the loudspeaker is

unwinked.

TIP: The loudspeaker can also be winked by

clicking the Wink button on the loudspeaker

RMS-equipped loudspeaker are RMS cable connectors and

mounting blocks for constructing RMS cables. The RMS

blocks allow Weidmuller connectors to be securely attached

to the RMS module with screws.

NEURON ID FOR RMS MODULE

Each RMS module has a unique 12-character Neuron ID (NID)

that identifies the loudspeaker on the network. The NID is

automatically detected by RMServer but can also be entered

manually, if necessary, when configuring RMS systems in

Compass RMS without loudspeakers present. The NID label

is located on the RMS user panel near the orange Network

connectors.

RESETTING THE RMS MODULE

Use the Identify button to reset the LYON RMS module when

powering on the loudspeaker. This action will cause the

module to be removed from the RMS network.

To reset the RMS module:

1.Power down the loudspeaker.

2.Press and hold the Identify button.

3.While continuing to hold down the Identify button, power

on the loudspeaker.

CHAPTER 6: SYSTEM DESIGN AND INTEGRATION TOOLS

This chapter introduces MAPP, Meyer Sound’s patented

system design tool, the Galileo GALAXY Network Platform,

and SIM, a comprehensive system for measurement and

analysis.

MAPP SYSTEM DESIGN TOOL

The MAPP System Design Tool (Figure 20) is a powerful,

cross-platform application for accurately predicting the

coverage pattern, frequency response, phase response,

impulse response, and SPL capability of single or arrayed

Meyer Sound loudspeakers.

Figure 20: MAPP System Design Tool

Whether planning for fixed installations or for tours with

multiple venues, use MAPP to accurately predict the

appropriate loudspeaker deployment for each job, complete

with coverage data, system delay and equalization settings,

rigging information, and detailed design illustrations. MAPP’s

accurate, high-resolution predictions ensure that systems

will perform as expected, thereby eliminating unexpected

coverage problems and minimizing onsite adjustments.

The key to the accuracy of MAPP’s predictions is

Meyer Sound’s exhaustive database of loudspeaker

measurements. Performance predictions for each

loudspeaker are based on 720 1/48th-octave-band

measurements taken with a SIM audio analyzer (see “” on

page 28) in the Meyer Sound anechoic chamber. The

extraordinary consistency between Meyer Sound

loudspeakers guarantees that predictions from MAPP will

closely match their actual performance.

MAPP client software allows for configuration of

Meyer Sound loudspeaker systems and definition of the

environment in which they operate, including air temperature,

pressure, humidity, and even the location and composition of

surfaces. Importation of CAD (.DXF) files containing detailed

venue information to act as a visual aid is also possible.

MAPP prediction requests are sent by the client software to

Meyer Sound servers, where complex, high-resolution

(magnitude and phase) polar data is processed with

sophisticated acoustical prediction algorithms. The resulting

predictions are then displayed in the MAPP client software.

TIP: Meyer Sound offers seminars and webi-

nars on using MAPP. For more information,

visit

www.meyersound.com

MAPP Capabilities

With MAPP, the user can:

•Simulate different loudspeaker configurations to refine

system designs and determine the best coverage for

intended audience areas

•Model loudspeaker interactions to locate constructive

and destructive interferences, so that loudspeakers can

be re-aimed and repositioned as necessary

•Place microphones anywhere in the sound field and

predict loudspeaker frequency response, phase

response, and sound pressure levels at each microphone

position

•Determine delay settings for fill loudspeakers using the

Inverse Fast Fourier Transform feature

•Preview the results of signal processing to determine

optimum settings for the best system response

•Automatically calculate load information for arrays to

determine necessary minimum rigging capacity,

front-to-back weight distribution, and center of gravity

location

•Generate and export system images and full-system PDF

reports for client presentations

LYON OPERATING INSTRUCTIONS

GALILEO GALAXY NETWORK PLATFORM

The Galileo GALAXY Network Platform is a sophisticated

loudspeaker management tool for controlling all

Meyer Sound speaker types. The GALAXY loudspeaker

processor extends a high level of audio control in driving

and aligning loudspeaker systems with multiple zones. It

provides a powerful tool set for corrective equalization (EQ)

and creative fine-tuning for a full range of applications from

touring to cinema.

Users can readily program the GALAXY processor using

Compass software running on a host computer or via the

Compass Go application for the iPad. Compass Control

Software includes custom-designed settings for each family

of speakers, as well as to integrate families together. For

example, the Product Integration feature matches the phase

characteristics between Meyer speaker families to ensure

the most coherent summation.

Processing tools for inputs and outputs include delay,

parametric EQ and U-Shaping EQ. Output processing also

includes polarity reversal, Low-Mid Beam control (LMBC),

atmospheric correction, and All Pass filters.

The built-in summing and delay matrices allow a user to

easily assign gain and delay values, respectively, at each

cross point. This capability greatly facilitates using one

loudspeaker to satisfy multiple purposes.

Front panel controls let a user intuitively and quickly operate

a GALAXY processor without a computer during live use.

The rear panel includes SIM bus port(s) for direct connection

to Meyer Sound’s SIM audio analyzer, allowing the GALAXY

processor to function as a line switcher for the analyzer.

With this capability, a user can take measurements from any

selection of GALAXY inputs and outputs without patching

beyond a single connection to the analyzer.

The GALAXY 408, GALAXY 816 and GALAXY 816-AES3

processor versions have the same audio processing capa-

bility with different I/O. See www.meyersound.com to locate

their datasheets for more information.

APPENDIX A: PRODUCT INTEGRATION

Product Integration combines both the Delay Integration setting and the Starting Points setting in a single dialog. By selecting

the loudspeaker model in the pop-up window, the Delay Integration and Starting Points drop-down menus are populated with

the available options. Using Product Integration is the first step to complete when optimizing a system. It is not recommended

for use when a system has previously been optimized, as some or all of the output processing filters and settings may be over-

written.

DELAY INTEGRATION

Delay Integration aligns the phase responses of different loudspeaker model families. Select the product and use the lowest

target phase curve frequency: 55-70, 100, or 125 (Hz) that is available for all of the loudspeaker models in a system. Not all

products will have every option available, with the exception of 125 Hz.

Figure 21 shows the Frequency and Phase Responses of the LEO (red line) and LYON (brown line) loudspeakers. Note the

phase differences, especially between 63 to 125 Hz.

Figure 21: LEO (red) and LYON (brown) Loudspeaker Phase Responses—No Delay Integration

LYON OPERATING INSTRUCTIONS

For the example shown in Figure 22, both products (LEO—magenta line, LYON—blue line) have been set to target phase

curves with a frequency of 100 Hz (pc100). The phase responses are now much more closely aligned than without Delay

Integration.

APPENDIX A: PRODUCT INTEGRATION

STARTING POINTS

The Starting Points feature lets a user recall files that are saved channel settings. In previous versions of Compass, these files

were referred to as Saved Settings. The Starting Points files are created and tested by the factory and are included in the

Compass software installation. Additional files can be created and stored by users for later recall.

Factory Starting Points files include two types of settings:

•Line Arrays:

U-Shaping filters are set to adjust the frequency response to a usable result. The response will be close to equal magni-

tude (flat) for arrays that are 6–8 elements.

There are several options for each model, based on the total splay angle between groups of loudspeakers, starting at the

top of the array. Select the Standard option to start. There are angles referred to in the file names, such as 1.5 to 5,

which refer to the total splay angle between groups of four loudspeakers.

•Gradient Subwoofer Arrays:

Gradient subwoofer arrays are assembled using groups of elements: forward-facing with rear-facing between them. The

Front-Facing selection for most models does not alter the signal processing. The Rear-Facing selection usually inverts

the polarity relative to the Front-Facing setting. Delay is also applied to synchronize the output of the rear-facing element

with the output of the front-facing elements behind the array.

NOTE: The Starting Points drop-down is populated from the files stored in both of the locations below. The

first location is a collection of all files that have been stored on the client computer. The second location

contains the current files distributed with Compass. Additional user created files can be created and stored in

either location.

NOTE: The software version number on a particular system may differ from what is shown below, but the

format of the link will be similar.

to different and often harsh weather conditions.

Meyer Sound Weather Protection includes a penetrating

treatment to raw wood, use of special primers, and plating

on all steel parts used (or alternatively, the use of stainless

steel hardware). Weather Protection is designed to prevent

malfunctions caused by harsh operating environments and

slows the accelerated wear and tear that occurs in outdoor

environments.

When Is Weather Protection Advisable?

Weather Protection is strongly recommended for all

permanent outdoor installations where loudspeakers are

directly exposed to the elements. This recommendation

includes desert and semi-arid climates, where protection

against dust and sand is important, and where infrequent

rainstorms can contribute to deterioration of loudspeaker

components.

Weather Protection is also recommended when the

loudspeakers are sheltered from direct exposure to

precipitation, but are nevertheless exposed to prolonged

high humidity, fog or mist. Examples would be installations

on covered outdoor terraces or pavilions.

Weather Protection is further advisable for portable or

touring systems when any significant outdoor use is

anticipated. Even though standard procedures may call for

using external protective measures, these are often not

implemented in time to prevent moisture intrusions that

could lead to premature performance degradation of the

loudspeaker.

Climate Variation and Owner Maintenance

The wear and tear on a loudspeaker will vary significantly

with different climatic conditions. For example, a

weather-protected loudspeaker installed in a

sunlight-exposed location on an ocean pier will experience

much harsher conditions than a loudspeaker in a similar

installation that is shaded by trees and exposed only to

rainfall. The constant exposure to direct UV radiation and a

salt air environment will cause a loudspeaker to wear more

quickly than one with partial UV shielding and exposed only

to freshwater moisture.

air environments, the exterior grille can quickly show signs

of oxidation, causing unsightly discoloration.

Apart from selecting suitable weather protection, the

progress of wear and tear on the loudspeaker can be

slowed by a regular schedule of inspection and cleaning.

This maintenance is particularly necessary in harsh

environments. Inspection and cleaning should include

routine removal of any visible oxidation or environmental

particulates, as these can accelerate metal corrosion or

decay of the cabinet. If installed loudspeakers are not in use

for an extended period, exterior protection or temporary

removal and storage of the loudspeakers should be

considered.

Benefits of Weather Protection

There are several benefits to selecting the Meyer Sound

Weather Protection option:

Functionality—Weather Protection prolongs the service life

of the loudspeaker by preventing premature degradation of

internal components.

Safety—Weather Protection lessens the chance of electrical

malfunctions or structural failures.

WARNING: IT IS THE RESPONSIBILITY OF

PURCHASERS/USERS/OPERATORS TO

SELECT WEATHER PROTECTION WHEN

APPROPRIATE FOR THEIR USE AND TO

PERIODICALLY INSPECT THEIR LOUDSPEAKER

INSTALLATIONS FOR ANY DETERIORATION THAT

MAY LEAD TO SAFETY CONCERNS.

Aesthetics—Weather Protection slows wear and tear on the

exterior of the loudspeaker in harsh conditions. Early signs

of wear and tear on the exterior of the loudspeaker indicate

over-exposure to the elements.

Standards Compliance—Weather Protection helps in

meeting IP ratings for loudspeakers. IP ratings are an

internationally recognized standard often used in

installations involving our products. A further explanation of

IP ratings is given in the “IP Ratings” Section on page 35.

Wear can eventually affect the performance of the

loudspeaker. It also affects aesthetics. For example, in salt

LYON OPERATING INSTRUCTIONS

WEATHER PROTECTION COMPONENTS

Standard Weather Protection

Meyer Sound designs toward an IP rating of IPX4 (see “IP

Ratings” on page 35) for Standard Weather Protection,

which includes the following components:

•Wood treatment—Prior to cabinet manufacturing, the

raw wood receives a special treatment that penetrates

and stabilizes the wood fibers to withstand a wide range

of temperatures and exposure to extreme humidity.

•Cabinet finishing—The assembled cabinets receive a

highly impervious finish that includes a sealing primer

and a finishing topcoat. The coatings are applied on both

surfaces, with one coat on the interior and two on the

exterior. The final step is a two-part modified acrylic

urethane similar to that used in military applications.

•Driver treatment—All cone drivers are coated with a

water-resistant sealant.

•Exterior protection—Grille frames are coated to resist

corrosion, and all components that mount to the cabinet

use custom gaskets and stainless steel fasteners.

If in doubt about an installation method, contact Meyer

Sound Technical Support for assistance.

Always discuss the environmental conditions of your Meyer

Sound installation with your Sales Manager, and verify the

availability of Weather Protection for your selected

loudspeaker models. The Sales Manager, together with

Technical Support, will verify the appropriate level of

weather protection for the loudspeakers and related rigging

hardware.

•Removable rain hood—The rain hood is designed to

shield connectors even in wind-driven rain.

INSTALLATION PRACTICES

Meyer Sound assumes normal and accepted installation

practices are used when installing Meyer Sound

Loudspeakers outdoors. Deviation from such practices may

cause weather protection to be ineffective and void the

warranty for the loudspeaker.

Examples of unacceptable and acceptable installation

practices include:

•Loudspeakers installed outdoors should not face

upward.

•Loudspeakers with a rain hood should be installed in

such a way that the rain hood opening is not facing any

direction but down.

•Meyer Sound-supplied rigging components should not

be modified (for example, by drilling additional holes in a

MUB for mounting to a wall). When an installer/integrator

modifies a Meyer Sound supplied rigging component to

support their installation method, it is considered

compromised and out of warranty.

•All loudspeaker cabling must be installed with a

“drip-loop” or equivalent method to ensure that rain or

water is NOT wicked toward the loudspeaker.

APPENDIX B: MEYER SOUND WEATHER PROTECTION

IP RATINGS

IP stands for “Ingress Protection.” The current format for expressing an IP rating is a 2-digit code. The first digit of an IP

rating represents protection from solid objects. The second digit of an IP rating represents protection from water or

moisture. Table 5 provides a chart of IP ratings and the corresponding definitions of the rating.

NOTE: IP ratings only apply to the “ENCLOSURE.” A loudspeaker is considered an enclosure and as such we

can apply an IP rating to it. Rigging hardware is not an enclosure and therefore IP ratings do not apply. Also,

cable and cable-mount connectors used to connect to the loudspeaker are NOT part of the enclosure and

therefore not part of the IP rating. Only the chassis-mounted part of the connector is considered part of the enclo-

sure.

M-noise is a full bandwidth (10 Hz–22.5 kHz) 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 band-

width Peak to RMS ratio of 18 dB. The presence of a greater-than (>) symbol with regard

to crest factor indicates it may be higher depending on EQ and boundary loading.

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.
