INTRODUCING THE JM-1P LOUDSPEAKER
The JM-1P self-powered loudspeaker is a high-Q, arrayable
loudspeaker suited for a wide range of applications. Utilizing
Meyer Sound's patented REM™ technology and trapezoidal
cabinet design, the JM-1P can be deployed in tightlypacked array clusters to deliver coverage that is proportional to the number of units in the array. While JM-1P point
source arrays are optimized for horizontal installations, they
can also be used vertically when necessary. With its scalable coverage and versatile QuickFly
JM-1P loudspeaker can be used for touring, rental, and
fixed installations.

JM-1P Arrayable Loudspeaker
Boasting a wide operating frequency range of 53 Hz to
18 kHz, the JM-1P delivers a remarkably smooth sound with
ample low-frequency headroom. Designed and manufactured at Meyer Sound headquarters in Berkeley, California,
the JM-1P's drivers include one low-frequency 15-inch long
excursion cone driver, and one high-frequency 4-inch compression driver with an REM manifold coupled to an
extremely accurate horn. The JM-1P is distinguished by its
constant-Q horn that provides a 20-degree horizontal by 60degree vertical coverage. The unit's consistent polar
response and trapezoidal enclosure allow for tightly packed
arrays with minimal overlap in high frequencies.

CHAPTER 1: INTRODUCTION
The JM-1P's sophisticated onboard amplification and processing produces consistent and predictable results in any
system design. A proprietary two-channel, class AB/H
power amplifier with complementary MOSFET output stages
yields a total power output of 1275 W (2550 W peak). Builtin signal processing includes an electronic crossover, driver
protection, and correction filters for achieving flat phase and
frequency responses. Each amplifier channel has peak and
rms limiters that prevent driver overexcursion and regulate
voice coil temperatures. Limiting activity is easily monitored
with the rear panel limit LEDs. The optional RMS™ remote
monitoring system provides comprehensive monitoring of
system parameters on a Windows
®
-based computer.
The JM-1P's end plates include captive GuideALinks™ and
quick-release pins that allow the unit to be easily linked with
other JM-1Ps in arrays. The optional MPA-JM1 pickup plate
suspends JM-1P horizontal arrays of up to four units with
uptilt or downtilt from a single hanging point; two pickup
plates can suspend arrays of up to six units from a single
hanging point or motor using the MTGSB-4B spreader bar.
The optional MTG-JM1 grid suspends vertical arrays of up
to six JM-1Ps.
MTG-JM1 Vertical Grid with Two JM-1Ps
Constructed of premium birch plywood, the durable JM-1P
enclosure is coated with a black-textured, hard-shell finish.
A 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. The
optional MDB-JM1 dolly board transports the JM-1P on
caster wheels; multiple dolly boards can be interlocked to
transport up to three linked JM-1Ps.

!
The JM-1P loudspeaker combines advanced loudspeaker
technology with equally advanced power capabilities.
Understanding power distribution, voltage and current
requirements, as well as electrical safety issues, is critical to
the safe operation of the JM-1P.
AC POWER DISTRIBUTION
All components in an audio system (self-powered loudspeakers, processors, etc.) 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 as the neutral and line cables.
NOTE: Improper grounding 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.
CAUTION: Before applying AC power to any
Meyer Sound self-powered loudspeaker, make
sure that the voltage potential difference between
neutral and earth ground is less than 5 V AC.
Figure 1 illustrates a basic three-phase AC distribution system with the loudspeaker load distributed across the three
phases. All loudspeakers are connected to common neutral
and earth-ground points.
THE AC CONNECTORS
The user panel on the back of the JM-1P includes the fol-
®
lowing PowerCon
JM-1P AC Input (left) and AC Loop Output (right) Connectors
AC connectors:
The AC Input Connector (Blue)
The blue AC Input connector supplies power to the JM-1P.
The connector is rated at 20 amps and uses a PowerCon AC
mains locking connector that prevents accidental disconnections. A 10-foot AC power cable, rated at 15 amps, is
included with each loudspeaker. If you replace the included
AC power cable, make sure to use a cable with the appropriate power plug (on the other end) for the area in which you
will operate the unit.
The AC Input connector also supplies power to any additional loudspeakers connected to the loudspeaker’s gray
Loop Output connector. Each JM-1P loudspeaker requires
approximately 5 A rms (maximum long-term continuous
current) at 115 V AC for proper operation.
Figure 1: AC Power Distribution System
CAUTION: When using the included AC power
cable, do not loop more than two additional
JM-1P loudspeakers from the AC Loop Output connector at 115 V (three total for the circuit), and not
more than five at 230 V (six total for the circuit).
The AC Loop Output Connector (Gray)
The gray AC Loop Output connector allows multiple JM-1P
loudspeakers to be looped and powered from a single
power source. Connect the AC Loop Output of the first
loudspeaker to the AC Input of the second, and so forth. The
AC Loop Output uses a PowerCon3 AC mains locking connector that prevents accidental disconnections.

The maximum number of loudspeakers that can be looped
from the Loop Output connector is determined by the voltage of the power source, the circuit breaker rating, and the
rating of the AC power cable connected to the first JM-1P
loudspeaker.

Each JM-1P loudspeaker ships with one AC looping connector for making AC looping cables. Assembled AC looping cables are available from Meyer Sound (15-inch UL AC
looping cable, PN 28.115.032.01; 0.35 m CE AC looping
cable, PN 28.115.032.02).
CAUTION: Do not exceed the current capabil-
ity of the 20-amp Input connector for the
JM-1P loudspeakers. When looping loudspeakers,
consider the total current draw for all loudspeakers
on the circuit, including the first loudspeaker.
When wiring international or special-purpose power connectors:
Connect the blue wire to the black terminal, or the termi-
nal marked with an N.
Connect the brown wire to the red terminal, or the termi-
nal marked with an L.
Connect the yellow and green wire to the green (or green
and yellow) terminal, or the terminal marked with an E.
CAUTION: When creating 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. The JM-1P requires a
grounded connection. Always use a grounded outlet
and plug. It is extremely important that the system be
properly grounded in order to operate safely and
properly. Do not ground-lift the AC cable.
JM-1P VOLTAGE REQUIREMENTS
The JM-1P operates safely and continuously when the AC
voltage stays within 95–125 V AC and 208–235 V AC at 50
or 60 Hz. The JM-1P allows any combination of voltage to
GND (neutral-line-ground or line-line-ground).
AC Connections with VEAM Cabling
The JM-1P can be ordered from the factory with a VEAM allin-one connector. VEAM connectors consolidate AC power,
audio, and RMS into a single cable, facilitating easy connections and quick setups. For more information, see
Appendix A, “Optional VEAM Multipin Connector.”
POWER CONNECTOR WIRING
The JM-1P requires a grounded outlet. To operate safely
and effectively, it is extremely important that the entire system be properly grounded.
AC Cable Wiring Scheme
If the voltage drops below 85 V (brownout), the JM-1P uses
stored power to continue operating temporarily; the loudspeaker will shut down if the voltage does not rise above the
low boundary before the stored power is used.
If the voltage rises above 235 V, the power supply could
become damaged.
CAUTION: The power source for the JM-1P
should always operate within the required voltage range, at least a few volts from the upper and
lower ranges. This will ensure that AC voltage variations from the service entry — or peak voltage drops
due to cable runs — will not cause the loudspeaker’s
amplifiers to cycle on and off or cause damage to the
power supply.
Powering Up the JM-1P
When AC power is applied to the JM-1P, its Intelligent AC™
power supply automatically selects the correct operating
voltage, allowing it to be used internationally without manually setting voltage switches. In addition, Intelligent AC also
suppresses high-voltage transients up to several kilovolts,
filters common mode and differential mode radio frequencies (EMI), and sustains operation temporarily during lowvoltage periods.

JM-1P OPERATING INSTRUCTIONS
!
!
When powering up the JM-1P, the following startup events
take place over several seconds.
1. Audio output is muted.
2. Voltage is detected and the power supply mode is automatically adjusted as necessary.
3. The power supply ramps up.
4. The green On/Temp LED on the user panel lights up,
indicating the loudspeaker is ready to output audio.
NOTE: The fan remains off at turn-on. It is con-
trolled by audio level and operates only at high
audio levels.
CAUTION: If the On/Temp LED does not light
up, or the loudspeaker does not output audio
after ten seconds, remove AC power immediately
and verify that the voltage is within the required
range. If the problem persists, contact Meyer Sound
Technical Support.
CAUTION: If either of the loudspeaker’s circuit
breakers trip (the white center buttons disengage), make sure to disconnect the AC power cable
before resetting the breakers. If necessary, contact
Meyer Sound for repair information.
JM-1P CURRENT REQUIREMENTS
The current draw for the JM-1P is dynamic and fluctuates as
operating levels change. Since 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 cable sizes and gauges conform to electrical
code standards. The current rating is also used as a rating for slow-reacting thermal breakers. In addition, the
Maximum Long-Term Continuous Current can be used to
calculate the AC looping capability of the JM-1P.
Burst Current — The maximum rms current during a
period of around one second. The Burst Current is used
as a rating for magnetic breakers. It is also used for calculating the peak voltage drop in long AC cable runs
according to the following formula:
V pk (drop) = I pk x R (cable total)
Ultimate Short-Term Peak Current — A rating for fast-
reacting magnetic breakers.
Inrush Current — The spike of initial current encoun-
tered when powering on.
You can use the following table as a guide for selecting
cable gauges and circuit breaker ratings for the system’s
operating voltage.

20.8 A peak 13.0 A peak 21.6 A peak
The minimum electrical service amperage required by a
JM-1P loudspeaker system is the sum of the Maximum
Long-Term Continuous Current for each loudspeaker. An
additional 30 percent above the minimum amperage is recommended to prevent peak voltage drops at the service
entry.
NOTE: For best performance, the AC cable
voltage drop should not exceed 10 V, or
10 percent at 115 V and 5 percent at 230 V. Make
sure that even with AC voltage drops that the AC
voltage always remains within the operating windows.

ELECTRICAL SAFETY ISSUES
Pay close attention to these important electrical and safety
issues.
The JM-1P 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.
Do not exceed the current capability of the 20-amp AC
Input connector for the loudspeaker. When looping loudspeakers, consider the total current draw for all loudspeakers on the circuit, including the first loudspeaker.
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. In addition, the AC power cable must be rated for the total current draw of all loudspeakers looped from the power
source.
Do not operate the unit if the power cables are frayed or
broken.
Keep all liquids away from the JM-1P to avoid hazards
from electrical shock.
12
Page 13
CHAPTER 3: AMPLIFICATION AND AUDIO
The JM-1P low- and high-frequency drivers are powered by
a proprietary two-channel Meyer Sound amplifier with
MOSFET output stages. The audio signal is processed with
an electronic crossover, correction filters for phase and frequency response, and driver protection circuitry. Each channel has peak and rms limiters that prevent driver overexcursion and regulate the temperature of the voice coil.
The user panel on the back of the JM-1P has two slots for
modules. The top slot contains an audio input module
(described in this chapter). The bottom slot is reserved for
the optional RMS module, used for connecting to the RMS
remote monitoring system (see Chapter 6, “The RMS
Remote Monitoring System”).
VEAM CABLING
The JM-1P can be ordered from the factory with a VEAM allin-one connector. VEAM connectors consolidate AC power,
audio, and RMS into a single cable, facilitating easy connections and quick setups. For more information, see
Appendix A, “Optional VEAM Multipin Connector.”
THE LOOPING AUDIO INPUT MODULE
The Looping Audio Input module includes input and looping
connectors, and LEDs for monitoring temperature and limiting.
Input Connector
The female XLR Input connector accepts a balanced audio
signal with an input impedance of 10 kOhm. The connector
uses the following wiring:
Pin 1 — 220 kOhm to chassis and earth ground (ESD
clamped)
Pin 2 — Signal (+)
Pin 3 — Signal (–)
Case — Earth (AC) ground and chassis
Pins 2 and 3 carry the input as a differential signal. Pin 1 is
connected to earth through a 220 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 standard, balanced XLR
audio cables with all three pins 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, and AC
power.
Looping Audio Input Module
Loop Connector
The male XLR Loop connector allows multiple JM-1P loudspeakers to be looped from a single audio source. Connect
the Loop output of the first loudspeaker to the Input of the
second, and so forth. The Loop connector is wired in parallel
to the Input connector and transmits the unbuffered source
signal even when the loudspeaker is powered off.
To avoid distortion when looping multiple JM-1P 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 20 dBV
(10 V rms into 600 ohms) to yield the maximum peak SPL
over the operating bandwidth of the loudspeaker.
13
Page 14
CHAPTER 3: AMPLIFICATION AND AUDIO
High-frequency limiter LED
Low-frequency limiter LED
!
To calculate the load impedance for the looped loudspeakers, divide 10 kOhms (the input impedance for a single
JM-1P) by the number of looped loudspeakers. For example, the load impedance for 10 JM-1P loudspeakers 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 JM-1P loudspeakers with other self-powered
Meyer Sound loudspeakers and subwoofers.
NOTE: Most source devices are capable of
driving loads no smaller than 10 times their
output impedance.
NOTE: 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 can be significantly degraded.
Limit LEDs
The low- and high-frequency drivers for the JM-1P are powered by separate amplifier channels, each with their own
limiter. Limiting activity is indicated with the two yellow Limit
LEDs. The top LED indicates limiting for the high-frequency
channel and the bottom LED indicates limiting for the lowfrequency channel. When engaged, a channel’s limiter not
only protects the driver, but also prevents signal peaks from
causing excessive distortion in the amplifier’s channel,
thereby preserving headroom and maintaining smooth frequency responses at high levels. When a channel’s level
returns to normal, below the limiter’s threshold, limiting
ceases.
The JM-1P performs within its acoustical specifications at
normal temperatures when the Limit LEDs are unlit, or if the
LEDs are lit for two seconds or less and then turn off for at
least one second. If an LED remains lit for longer than three
seconds, that channel enters hard limiting where:
Increases to the input level have no effect.
Distortion increases due to clipping and nonlinear driver
operation.
The driver is subjected to excessive heat and excursion,
which will compromise its life span and may eventually
lead to damage over time.
CAUTION: The Limit LEDs indicate when a
safe, optimum level is exceeded. If a JM-1P
loudspeaker begins to limit before reaching the
required SPL, consider adding more loudspeakers to
the system.
NOTE: The JM-1P loudspeaker uses optical
limiters that add no noise and have no effect
on the signal when the limiters are not engaged and
the Limit LEDs are not lit.
On/Temp LED
When the JM-1P is powered on, its On/Temp LED turns
green. If the temperature of the heat sink reaches 85° C
(185° F), the On/Temp LED changes from green to red and
the limiter threshold is lowered to a safe level to prevent the
system from overheating. Under high temperature conditions the output level is reduced by approximately 6 dB.
When the heat sink temperature decreases to 80° C
(176° F), the On/Temp LED changes from red back to green
and the limiter threshold returns to normal.
Limit LEDs
14
NOTE: When the On/Temp LED is red, this is
an indication that the unit is reaching its maximum dissipation and a reduction in SPL is recommended.
TIP: When the JM-1P is connected to an RMS
network, the RMS software provides additional
feedback on the loudspeaker’s operating temperature. For more information, see Chapter 6, “The RMS
Remote Monitoring System.”

AMPLIFIER COOLING SYSTEM
The amplifier for JM-1P uses natural convection for cooling
at low to moderate audio levels; for high audio levels, it uses
Meyer Sound’s proprietary QuietCool fan technology to prevent overheating. The QuietCool™ fan only engages at high
audio levels, making it virtually inaudible.
CAUTION: To keep the JM-1P from getting too
hot, allow for proper ventilation around the
loudspeaker, especially when it is operated in tightly
packed conditions.
CAUTION: In the unlikely event that the heat
sink temperature for the JM-1P reaches 95° C
(203° F), the loudspeaker will automatically shut
down until AC power is removed to allow the heat
sink to cool. If after cooling and reapplying AC power
the loudspeaker shuts down again, contact Meyer
Sound for repair information.
QuietCool Fan Technology
CAUTION: The heat sink for the JM-1P can
reach temperatures of up to 85° C (185° F) during extreme operation. Use extreme caution when
approaching the rear of the loudspeaker.

SIGNAL / CLIP
MUTE
700-HP subwoofers can be added to JM-1P loudspeaker
systems to enhance the low-frequency response and
increase the overall acoustic power of the system in the lowest frequencies. The ideal ratio of JM-1P loudspeakers to
700-HP subwoofers depends on the frequency content of
the source material and headroom required for low frequencies.

Recommended Ratio
(Number of JM-1Ps per Subwoofer)
2 x 1 for normal applications
3 x 2 for bass-heavy applications
requiring additional low-frequency
headroom
700-HPs can be added to JM-1P systems by daisy-chaining
them to JM-1P loudspeakers. Full-range signals can be
connected directly to Meyer Sound self-powered loudspeakers because the loudspeakers have built-in active
crossovers. In more complex systems, subwoofers should
be integrated using line drivers or digital signal processor to
send multiple outputs to each sub-system. In addition, you
can use low-cut filters to flatten the overall frequency
response of the system while increasing the JM-1P headroom in the lower frequencies.
THE GALILEO LOUDSPEAKER MANAGEMENT SYSTEM
Meyer Sound’s Galileo® loudspeaker management system is
a comprehensive solution for driving and aligning loudspeaker systems, especially those comprised of Meyer
Sound self-powered loudspeakers. The system is available
in two hardware configurations:
The Galileo 616 is a two-space rack unit with six inputs
and 16 low-latency outputs. Processing for the outputs
includes gain, polarity, delay, high- and low-pass filters,
equalization (parametric and TruShaping), and atmospheric correction.
Galileo 616
The Galileo 408 shares the same 24-bit, 96 kHz audio
quality and 32-bit floating point internal processing as
the Galileo 616, though with fewer inputs and outputs.
NOTE: When JM-1P loudspeakers and
700-HP subwoofers are daisy-chained using
the JM-1P’s Loop connector, the result is a fairly flat
frequency response. However, the response will show
an increase in the 60 Hz – 200 Hz range where the
loudspeaker and subwoofer overlap at certain ratios
(see Table 2).
NOTE: If the 700-HP exhibits limiting (its Limit
LED lights) before reaching the required SPL,
consider adding more subwoofers to meet the SPL
requirements without exposing the drivers to excessive heat and excursion.
TIP: MAPP Online Pro™ can be used to accu-
rately predict the appropriate loudspeaker and
subwoofer integration in systems, complete with coverage data, system delay and equalization settings,
rigging information, and detailed design illustrations.
For more information, see “MAPP Online Pro” on
page 31.
Galileo 408
All system parameters for the Galileo 616 and Galileo 408
can be configured from the extensive Compass™ software
®
running on a Windows or Mac
computer. The Galileo 616
can also be configured from its intuitive front panel controls.
The Galileo system interfaces seamlessly with Meyer
Sound’s SIM
®
3 audio analyzer.
TIP: The Galileo 616 and Galileo 408 include
presets optimized for JM-1P loudspeaker sys-
tems.

CHAPTER 4: ADDING SUBWOOFERS TO A JM-1P LOUDSPEAKER SYSTEM
USING DIGITAL SIGNAL PROCESSORS
Full-range signals can be connected directly to Meyer
Sound self-powered loudspeakers because the loudspeakers have built-in active crossovers. External crossovers and
digital signal processors are optional and should be used
with caution as they can introduce phase shifts that cause
destructive cancellations.
If a digital signal processor is used, both the JM-1P loudspeakers and subwoofer should be driven from the same
processor to keep their delay times the same. Otherwise a
phase shift between the JM-1Ps and subwoofer may be
encountered. In addition, you should verify the delay time
between channels: some digital signal processors may incur
channel-to-channel delays when the processor is near maximum throughput, which becomes more likely as the number
of filters in use by the processor is increased.
Third-order filters (and higher) are not recommended. If they
must be used, they should be used cautiously, since they
may cause phase shifts that deteriorate the impulse
response; in addition, their higher roll-off may also interfere
with crossover interaction.
TIP: To address the collective concerns of sys-
tem design verification, subwoofer integration,
digital signal processors, delay systems, and acoustical conditions, a measurement system like Meyer
Sound’s SIM 3 is strongly recommended.

CHAPTER 5: QUICKFLY RIGGING
!
The JM-1P loudspeaker is compatible with Meyer Sound’s
QuickFly system, a comprehensive collection of customdesigned rigging, flying, and mounting options. Comprised
of rugged, reliable, and easy-to-configure components,
QuickFly lets you deploy JM-1P loudspeakers as arrays at
precise angles to take full advantage of their directional
components. The top and bottom plates for the JM-1P cabinets are constructed of heavy-duty, high-strength, corrosion-resistant 6061-T6 aluminum and include threaded
metric holes (for M10 screws) for easy connection to QuickFly rigging and third-party mounting options.
Important Safety Considerations!
When installing Meyer Sound loudspeakers, 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 reliability 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.
THE JM-1P GUIDEALINKS
The JM-1P is equipped with GuideALinks on its four right corners that attach to an adjacent JM-1P with the links inserted
in the left corner slots of the linked unit. GuideALinks are
extended and retracted with front and rear knobs. The links
are secured to the linked JM-1P with the quick-release pins
included with each loudspeaker. GuideALinks are also used
when flying JM-1Ps from the MTG-JM1 vertical grid.
Make sure to attach mounting hardware to the building's
structural components (studs or joists), and not just to
the wall surface. Verify that the building's structure and
the anchors used for the installation will safely support
the total weight of the mounted loudspeakers.
Use mounting hardware appropriate for the surface
where the loudspeaker will be installed.
Make sure bolts and eyebolts are tightened securely.
Meyer Sound recommends using Loctite
®
on eyebolt
threads and safety cables.
Inspect mounting and rigging hardware regularly. Imme-
diately replace any worn or damaged components.
JM-1P GuideALinks
CAUTION: When moving and linking JM-1Ps,
avoid placing fingers between the units to pre-
vent injury.

CHAPTER 6: THE RMS REMOTE MONITORING SYSTEM
An optional RMS remote monitoring system module can be
installed in the JM-1P, allowing it to be connected to an
RMS network. RMS allows real-time monitoring of multiple
Meyer Sound self-powered loudspeakers from a Windowsbased computer. The RMS host computer communicates
with Meyer Sound loudspeakers (equipped with RMS modules) via a simple twisted pair network, or an Ethernet network using an FT-10 to Ethernet adapter.
NOTE: For the latest RMS system require-
ments, go to the Meyer Sound website
(http://www.meyersound.com
NOTE: RMS-equipped loudspeakers include a
Mute Jumper that can be installed to enable
the loudspeaker’s mute and solo capability. Meyer
Sound currently ships RMS-equipped loudspeakers
with the Mute Jumper installed. These mute-enabled
loudspeakers can be identified by the blue “ME”
sticker on the face of the RMS module. Older RMSequipped loudspeakers can easily be mute-enabled
by installing the Mute Jumper. For more information,
refer to the RMS User Guide.
).
THE RMS SOFTWARE
The optional RMS software provides extensive system status and performance data for each loudspeaker, including
amplifier voltage, limiting activity, power output, 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 commissioning procedure where the loudspeaker is identified by either entering its unique Neuron ID,
or by pressing its Service button.
RMS Add Loudspeaker Dialog Box
NOTE: The RMS software allows you to dis-
able Mute and Solo functions to eliminate any
possibility of accidentally muting loudspeakers. Mute
and solo capability can also be disabled by removing
the Mute Jumper from RMS modules. For more information, refer to the RMS User Guide.
NOTE: RMS does not control AC power.
Once loudspeakers are identified on the RMS network, they
appear in the RMS software as icons and views; they are
also automatically added to the RMS database on the host
computer.
JM-1P RMS Icon

Page 28
CHAPTER 6: THE RMS REMOTE MONITORING SYSTEM
The RMS software displays all loudspeakers on the network
in a panel with icons, Meter views, and Text views that can
be customized to suit your needs. Loudspeaker data is
updated 2–5 times per second. Individual loudspeakers can
be physically identified with the Wink option in RMS, which
lights the Wink LED on the RMS module for that particular
loudspeaker. Conversely, a loudspeaker can be identified in
the RMS software by pressing the Service button on the
loudspeaker’s RMS module.
THE RMS MODULE
The RMS module is installed in the bottom slot of the user
panel on the back of the Meyer Sound loudspeaker. The
RMS user panel has three LEDs, two buttons, and two Network connectors.

NOTE: The LEDs and buttons on the RMS user
panel are used exclusively by RMS and have
no effect on the acoustical or electrical activity of the
JM-1P loudspeaker.
Service LED (Red)
The red Service LED provides the following feedback:
When unlit, the loudspeaker is successfully connected to
the network and commissioned.
RMS User Panel
Loudspeaker icons and views can be arranged to represent
how the loudspeakers have been deployed in the system.
Multiple panels can be saved and recalled for specific performances and venues.
NOTE: When the heat sink for the JM-1P
reaches 85° C (185° F), the On/Temp LED turns
red, while its loudspeaker icon in the RMS software
turns yellow — indicating the loudspeaker is running
hot, but still within safe operating limits. Make sure
that the loudspeaker is properly ventilated.
When blinking once every two seconds, the loudspeaker
is connected to the network but not yet commissioned in
the RMS software.
When lit continuously, the loudspeaker’s RMS hardware
has failed and may indicate that the module has been
damaged (contact Meyer Sound Technical Support).
NOTE: The Service LED on the RMS user
panel is used exclusively by RMS and has no
effect on the acoustical or electrical activity of the
JM-1P loudspeaker.
Service Button
Pressing the Service button identifies the loudspeaker on
the RMS network and notifies the RMS software that the
loudspeaker is connected. You can simultaneously press the
Reset and Service buttons to reset the RMS module and
decommission the loudspeaker from the network (see
“Resetting the RMS Module” on page 29).
28

Wink LED (Green)
The green Wink LED lights when a signal is sent from the
RMS software by clicking the Wink button on the loudspeaker’s icon or on its Text view. This is useful for identifying the physical loudspeaker corresponding to a
loudspeaker icon in the RMS software.
Reset Button
Pressing the Reset button causes the RMS module’s firmware to reboot; this will not affect whether the loudspeaker
is commissioned (which is stored in flash memory). You can
simultaneously press the Reset and Service buttons to reset
the RMS module and decommission the loudspeaker from
the network (see “Resetting the RMS Module” on page 29).
Activity LED (Green)
The green Activity LED flashes continuously when the loudspeaker has been successfully commissioned.

CHAPTER 7: SYSTEM DESIGN AND INTEGRATION TOOLS
Meyer Sound offers two comprehensive tools to assist with
the acoustical and functional requirements of system design
and optimization. This chapter introduces you to MAPP
Online Pro, Meyer Sound’s patented online acoustical prediction tool, and SIM 3, a comprehensive system for measurement and analysis.
MAPP ONLINE PRO
MAPP Online Pro is a powerful, cross-platform, Java-based
application for accurately predicting the coverage pattern,
frequency response, impulse response, and maximum SPL
output of single or arrayed Meyer Sound loudspeakers.
Residing on your local computer, the MAPP Online Pro client
lets you configure Meyer Sound loudspeaker systems and
define the environment in which they will operate, including
air temperature, pressure, humidity, and even the location
and composition of walls. CAD (DXF) files containing
detailed venue information can also be imported.
detailed design illustrations. MAPP Online Pro’s accurate,
high-resolution predictions ensure that systems will perform
as expected, thereby eliminating unexpected coverage
problems and minimizing on-site adjustments.
The key to the accuracy of MAPP Online Pro’s predictions is
its exhaustive database of Meyer Sound loudspeaker measurements. Performance predictions for each loudspeaker
are based on 360 1/48th-octave-band measurements taken
with a SIM audio analyzer in the Meyer Sound anechoic
chamber. The extraordinary consistency between Meyer
Sound loudspeakers guarantees that predictions from
MAPP Online Pro will closely match their actual performance.
MAPP Online Pro predictions are requested by the client
software and sent via the Internet to the high-speed Meyer
Sound servers where high-resolution (magnitude and phase)
polar data is processed with sophisticated acoustical prediction algorithms. The resulting predictions are then
returned to and displayed on the local computer running the
MAPP Online Pro client software.
MAPP Online Pro Applications
With MAPP Online Pro, you can:

Source Independent Measurement Technique
The SIM 3 audio analyzer implements Meyer Sound’s source
independent measurement technique, a dual-channel
method that accommodates statistically unpredictable excitation signals. Any excitation signal within a desired frequency range can be used to obtain highly accurate
measurements for acoustical or electronic systems. For
example, concert halls and loudspeaker systems can be
captured during a performance and used as a SIM 3 test
signal, so you can:
■ View measurement data as amplitude versus time
(impulse response) or amplitude and phase versus frequency (frequency response)
■ Utilize a single-channel spectrum mode
■ View frequency domain data with a logarithmic fre-
quency axis
■ Determine and internally compensate for propagation
delays using the SIM 3 Delay Finder
SIM 3 Applications
SIM 3’s main applications are testing and aligning loudspeaker systems, which entails:
■ Measuring propagation delays between subsystems to
determine appropriate polarities and delay times
■ Measuring variations in frequency response caused by
the acoustical environment and the placement and interaction of loudspeakers to determine corrective equalization
■ Optimizing subwoofer integrations
THE SIM 3 MEASUREMENT SYSTEM
The SIM 3 audio analyzer is a high-resolution audio measurement system comprised of software, hardware, microphones, and accessory cables. SIM 3 is optimized for
measuring audio frequencies with resolutions up 1/48th of
an octave, allowing you to apply precise corrections to balance system response using frequency and phase domain
information.
32
■ Optimizing loudspeaker arrays
SIM 3 can also be used in the following applications:
■ Microphone calibration and equalization
■ Transducer evaluation and correction
■ Echo detection and analysis
■ Vibration analysis
■ Architectural acoustics
■ Underwater acoustics

APPENDIX A: OPTIONAL VEAM MULTIPIN CONNECTOR
Line (brown)
Ground (green/yellow)
Neutral (blue)
The JM-1P can be ordered from the factory with a VEAM allin-one connector. VEAM connectors consolidate AC power,
audio, and RMS into a single cable, facilitating easy connections and quick setups.
JM-1P loudspeakers require a grounded outlet. It is very
important that the system be properly grounded in order to
operate safely and properly. Figure 3 illustrates correct wiring for the creation of power cables and distribution systems
for JM-1P loudspeakers equipped with VEAM multipin connectors.

A weather-protected version of the JM-1P is available with
rain hood kits that safeguard the loudspeaker’s electronics
from the elements in fixed, outdoor installations. The rain
hood is available in both vertical (PN 40.185.038.01) and
horizontal (PN 40.185.084.02) versions. The rain hood kits
are comprised of an upper rain hood that protects the heat
sink, and a lower rain hood that protects the user panel and
connectors. The rain hoods are made of a durable, highimpact polycarbonate that is also transparent, allowing the
loudspeaker's connections and LEDs to be visible.
VERTICAL RAIN HOOD KIT CONTENTS
The JM-1P vertical rain hood is used when the loudspeaker
is oriented vertically. The JM-1P vertical rain hood kit
(PN 40.185.038.01) includes the following parts:
