Meyer Sound Documentation

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.

120V AC, 3-Phase Wye System (Single Line) — Line-Neutral-Earth/Ground

The figure below illustrates a basic 120V 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 120V AC to each loudspeaker.

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

Line-Line-Earth/Ground

The figure below illustrates a 120V AC, 3-phase Wye distribution system with each loudspeaker connected to two lines and a common earth/ground line. This configuration is possible because LEOPARD tolerates elevated voltages from the ground line and does not require a neutral line. This system delivers 208V AC to each loudspeaker.

120V 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 audible hum.

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

Line-Neutral-Earth/Ground

The figure below illustrates a basic 230V 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 230V AC to each loudspeaker.

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

Caution

For 230V AC, 3-phase Wye systems, never connect two lines to the AC input of LEOPARD, as the resulting voltage would exceed the upper voltage limit (275V AC) and will damage the loudspeaker.

The LEOPARD user panel includes two powerCON 20 connectors, as shown in the figure below, one for AC Input (blue) and one for AC Loop Output (gray).

AC Input (Left) and AC Loop Output (Right) Connectors

AC Input (Blue)

The blue AC Input connector supplies power to LEOPARD. The 3-conductor powerCON 20 is rated at 20 A and uses a locking connector that prevents accidental disconnections. A 10-foot AC power cable, rated at 15 A, 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 loudspeaker. LEOPARD requires a grounded outlet. To operate safely and effectively, it is extremely important that the entire system be properly grounded.

The AC Input connector also supplies power to any additional loudspeakers connected to the loudspeaker’s gray Loop Output connector.

Caution

When looping AC power for loudspeakers, do not exceed the current capability of the AC Input connector (20 A) or the included AC power cable (15 A). Consider the total current draw for all loudspeakers on the circuit, including the first loudspeaker. See AC Loop Output (Gray) for more information.

AC Loop Output (Gray)

The gray AC Loop Output connector allows multiple LEOPARDs to be looped and powered from a single power source. The 3-conductor powerCON 20 is rated at 20 A and uses a locking connector that prevents accidental disconnections. For applications that require multiple LEOPARDs, connect the AC Loop Output of the first loudspeaker to the AC Input of the second loudspeaker, and so forth.

The maximum number of loudspeakers that can be looped from the AC Loop Output connector is determined by the voltage of the power source, the current draw of the looped loudspeakers, the circuit breaker rating, and the rating of the AC power cable connected to the first LEOPARD loudspeaker, as shown in the table below.

Table 1. Maximum LEOPARDs that Can Be Looped with AC Power

Circuit Breaker/ Connector Rating	115 V AC	230 V AC	100 V AC
15 A / 16 A	4 looped (5 total)	9 looped (10 total)	3 looped (4 total)
20 A	5 looped (6 total)	12 looped (13 total)	4 looped (5 total)

Note

Current draw for LEOPARD is dynamic and fluctuates as operating levels change. The indicated number of loudspeakers that can be looped assumes that operating levels are normal and not such that loudspeakers are constantly limiting.

LEOPARD ships with a gray powerCON 20 cable mount connector, rated at 20 A, for assembling AC looping cables. Assembled AC looping cables are also available from Meyer Sound.

Caution

When looping AC power for loudspeakers, do not exceed the current capability of the AC Input connector (20 A) or the included AC power cable (15 A). Consider the total current draw for all loudspeakers on the circuit, including the first loudspeaker, as shown in the table above.

LEOPARD ships with a gray powerCON20 cable mount connector rated at 20A, for assembling AC looping cables, as shown in the figure below. The pins on the powerCON20 cable mount connector are labeled as follows:

powerCON 20 Cable Mount Connector

How AC power cables are wired is determined by the type of AC power distribution system used ( see AC Power Distribution). When wiring AC power cables for single-line systems, use one of the wiring schemes described in the table and illustrated in the figure below:

AC Wiring Scheme, illustrated

LEOPARD operates as intended when receiving AC voltage within the following range:

If the voltage drops below 90 V, 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.

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.

Use the information provided in the table below 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.

LEOPARD’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 frequencies (EMI), and sustains operation temporarily during low-voltage periods

Powering on LEOPARD

When powering on LEOPARD, 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. On the user panel, the Active/Status LED flashes multiple colors successively.

5. The Active/Status LED turns solid green, indicating the loudspeaker is unmuted and ready to output audio.

Caution

If the Active/Status LED does not turn solid green, or LEOPARD 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.

Make sure to observe the following important electrical and safety guidelines.

LEOPARD is available with XLR 5-pin or 3-pin connectors for audio Input and audio Loop output, as shown in the figures below. XLR 5-pin connectors accommodate both balanced audio and RMS signals.

XLR 5-Pin Audio Connectors, Input and Loop Output

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.

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 electrical 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 11). For applications that require multiple LEOPARDs, connect the Loop output of the first loudspeaker to the Input of the second loudspeaker, and so forth.

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 LEOPARDs 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 LEOPARDs with other Meyer Sound self-powered loudspeakers.

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 output 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.

LEOPARD 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 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 LEOPARD are powered by separate amplifier channels, each with their own limiter. Limiting activity is indicated with two Limit LEDs on the user panel, as shown i n the figure below. The HF Limit LED indicates limiting for the high-frequency channel and the LF Limit LED indicates limiting for the low-frequency channel.

LEOPARD 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.

LEOPARD 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 3 seconds, 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 LEOPARD loudspeaker system begins to limit before reaching the desired SPL, consider adding more loudspeakers to the system.

LEOPARD is convection cooled. The amplifier’s heat sink provides natural convection cooling from the air flowing near its fins. When exposed to high ambient temperatures or when driven continuously at high output levels, a variable-speed fan circulates air internally to ensure that LEOPARD remains operational.

During normal operation, when LEOPARD is powered on, the Active/Status LED is solid green. If the loudspeaker encounters a hardware fault, or the loudspeaker begins to overheat, the LED flashes red. In some instances, the loudspeaker will continue to output audio while the LED flashes red, though with a reduction in the limiter threshold and acoustic output to protect the loudspeaker.

If a loudspeaker is overheating (for RMS-equipped loudspeakers, you can verify this situation in Compass RMS), a reduction in SPL may be necessary. If, after a reduction in SPL and an appropriate cooling period, the Active/Status LED continues to flash red (does not return to solid green), contact Meyer Sound Technical Support.

If the Active/Status LED flashes red and the loudspeaker does not output audio, contact Meyer Sound Technical Support immediately.

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

The table below summarizes the available rigging options for LEOPARD. For complete information about rigging hardware, including dimensions, weight, configuration, and load ratings, refer to the MG-LEOPARD/900 Assembly Guide (PN 05.243.080.01).

Rigging Example, LEOPARD Array with Pull-Back

Rigging Example, Mixed Array with 900-LFCs and LEOPARDS

Rigging Example, LYON Array with LEOPARD Downfill

LEOPARD is equipped with four captive GuideALinks and four mating links slots that link to adjacent LEOPARDs or 900-LFCs in flown and groundstacked arrays. Located at the top corners of the cabinet, GuideALinks extend up and into the link slots of the cabinet above it ([→ _bookmark35]Figure 16 and [→ _bookmark36]Figure 17), or into the link slots of the MG-LEOPARD/900 grid or MTF-LYON/LEOPARD transition frame. GuideALinks extend and retract with knobs and are secured with two quick-release pins: one each in the top and bottom cabinets. Each LEOPARD loudspeaker ships with eight 5/16 x 0.063-inch quick-release pins (black button) (PN 134.024).

LEOPARD GuideALinks with Quick-Release Pins, Exploded View

LEOPARD Splay Angles

Front GuideALinks attach at splay angles of 0 or +5 degrees. However, the front GuideALinks should almost always be attached at 0 degrees, to ensure that coverage between

linked cabinets is continuous. When attached at 0 degrees, the front GuideALinks act as a pivot point between the linked LEOPARDs, with the splay angle between the units determined by the rear GuideALink positions. When attached at +5 degrees, the front GuideALinks add 5 degrees to the splay angle configured with the rear GuideALinks, making it possible to achieve splay angles of 11 to 15 degrees. To stow the front GuideALinks, move them all the way down to STOW and pin them.

Tip

Wide splay angles of 11 to 15 degrees should only be used for downfill coverage, or for steering coverage away from structures like balconies.

LEOPARD GuideALinks (Exposed) Attached at 0.5 Degrees

Rear GuideALinks attach at splay angles of 0.5 to 10 degrees. The labels next to the rear GuideALinks indicate the splay angle between cabinets and provide a guide for which of the three pinning positions to use to secure the links, as shown in the figure below. As the links are moved down, the splay angle increases. To stow the rear GuideALinks, move them all the way down to STOW and pin them to the center pin position.

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.

LEOPARD Rear GuideALinks Label

Note

For more information on GuideALink configurations, refer to the MG-LEOPARD/900 Assembly Guide (PN 05.243.080.01).

LEOPARD Splay Angles for Top Flown Cabinets

When flying LEOPARDs below the 900-LFC, MG- LEOPARD/900 grid, or MTF-LYON/LEOPARD transition frame, splay angles of –4.5 to +10 degrees are possible for the top cabinet with the GuideALink configurations listed in the table below.

Table 5. LEOPARD (Top Cabinet) GuideALink Configurations

Rear GuideALinks Set To	Front GuideALinks Set To	Resulting Angle of Attachment
.5°	0°	–4.5°
1°	0°	–4°
2°	0°	–3°
3°	0°	–2°
4°	0°	–1°
5°	0°	0°
6°	0°	1°
7°	0°	2°
8°	0°	3°
9°	0°	4°
10°	0°	5°
6°	+5°	6°
7°	+5°	7°
8°	+5°	8°
9°	+5°	9°
10°	+5°	10°

Note

When flying LEOPARDs from the MG-LEOPARD/900 grid, a splay angle of 0 degrees is recommended for the top cabinet (rear GuideALinks set to 5, front GuideALinks set to 0) to ensure that the cabinet aligns with any lasers or inclinometers mounted on the grid. To add tilt to the top cabinet, the actual grid should instead be tilted with motors attached to the front and rear of the grid. If just one motor is available, you can attach it to one of the 13 center pickup points offset from the center of the grid to achieve the desired tilt.

MAPP 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.

MAPP System Design Tool

Whether planning for fixed installations or for tours with multiple venues, you can 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 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 lets you configure Meyer Sound loudspeaker systems and define the environment in which they operate, including air temperature, pressure, humidity, and even the location and composition of surfaces. You can also import CAD (.DXF) files containing detailed venue information to act as a visual aid.

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.

With MAPP, you can:

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 Model View space 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 and phase response 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 system PDF reports for client presentations

• Synchronize GALAXY processor output channel settings in real-time with virtual or real GALAXY units, allowing in-the-field changes to be predicted during system alignments

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 toolset 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. Connecting MAPP to the GALAXY processor will also allow the user to push output channel settings created in MAPP as a starting point. 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 GALAXY 408, GALAXY 816, and GALAXY 816-AES3 processor versions have the same audio processing capability with different I/O.

Weather Protection is strongly recommended for all permanent outdoor installations where loudspeakers are directly exposed to the elements. This 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.

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 salt air environment will cause a loudspeaker to wear more quickly than one with partial UV shielding and exposed only to freshwater moisture.

Wear can eventually affect the performance of the loudspeaker. It also affects aesthetics. For example, in salt 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.

There are several benefits to selecting the Meyer Sound Weather Protection option:

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:

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.

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. The table below provides a chart of IP ratings and the corresponding definitions of the rating.

Weather-protected LEOPARDs include a quick-clip removable rain hood for indoor/outdoor touring and sheltered outdoor installations.

The LEOPARD quick-clip removable rain hood (Figure 24) is easily attached and removed with its two winghead studs.

Another option for weather-protected LEOPARDs is the collapsible rain hood.
