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 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.

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

120V AC, 3-Phase Wye System (Two Lines) -- Line-Line-Earth/Ground

The figure below 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 ULTRA-X20/22/23 tolerates elevated voltages from the ground line and does not require a neutral line. This system delivers 208 V AC to each loudspeaker.

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 audible hum.

230V AC, 3-Phase Wye System (Single Line) -- Line-Neutral-Earth/Ground

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

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

Caution

For 230 V AC, 3-phase Wye systems, never connect two lines to the AC input of ULTRA-X20/22/23, as the resulting voltage would exceed the upper voltage limit (275 V AC) and will damage the loudspeaker.

The ULTRA-X20/22/23 user panel includes two powerCON 20 connectors, shown in the figure below, one for AC Input (blue) and one for AC Loop Output (gray).

AC Input (Top) and AC Loop Output (Bottom) Connectors

The weather-protected and digital versions use the extremely robust PowerCON TRUE1 TOP (Total Outdoor Protection) chassis connector, shown in the figure below.

PowerCON TRUE1 TOP Connector Panel (Input Sealing Cover Open, Loop Sealing Cover Closed)

AC Input (Blue)

The blue AC Input connector supplies power to ULTRA-X20/22/23. 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 the included AC power cable is replaced, make sure to use a cable with the appropriate power plug (on the other end) for the region where the unit will be operated. ULTRA-X20/22/23 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 ([→ _bookmark15]Table 1).

AC Loop Output (Gray)

The gray AC Loop Output connector allows multiple ULTRA-X20/22/23 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 ULTRA-X20/22/23, 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 ULTRA-X20/22/23 loudspeaker, as described in the table below.

Table 1. Maximum ULTRA-X20/22/23s that Can Be Looped with AC Power

Circuit Breaker/ Connector Rating	115 V AC	230 V AC	100 V AC
15 A	10 looped (11 total)	20 looped (21 total)	8 looped (9 total)
20 A	16 looped (17 total)	29 looped (30 total)	12 looped (13 total)

Note

Current draw for ULTRA-X20/22/23 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.

ULTRA-X20/22/23 ships with a gray powerCON20 cable mount connector, rated at 20A, for assembling AC looping cables. Assembled 1-meter AC looping cables are also available from Meyer Sound.

ULTRA-X20/22/23 ships with a gray powerCON 20 cable mount connector, rated at 20 A, for assembling AC looping cables, as shown in the figure below. The pins on the powerCON 20 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 shown in the figure below and described in the table below:

AC Wiring Scheme

ULTRA-X20/22/23 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 in the table below to select the appropriate cable gauge and 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.

ULTRA-X20/22/23’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 the ULTRA-X20/22/23

When powering on the ULTRA-X20/22/23 loudspeaker, 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 Limit and On/Status LED flashes multiple colors successively.

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

Caution

If the Limit and On/Status LED does not turn solid green, or the ULTRA-X20/22/23 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.

AMPLIFICATION AND AUDIO CONNECTORS

The ULTRA-X20/22/23 drivers are powered by a proprietary three-channel, open-loop, class D amplifier. The audio signal is processed with electronic crossover, 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.

TRUPOWER LIMITING

The ULTRA-X20/22/23 employs Meyer Sound’s advanced TruPower® limiting. Conventional limiters assume a constant driver impedance and set the limiting threshold by measuring voltage alone. This method is inaccurate, because driver 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 driver 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.

ULTRA-X20/22/23 ANALOG VERSION USER PANEL

The ULTRA-X20/22/23 Analog Version user panel, shown in the figure below, includes XLR Input and Loop output connectors for audio, a Limit and On/Status LED, and optional RMS connectors and controls (see RMS Remote Monitoring System).

ULTRA-X20/22/23 User Panel (5-pin XLR and optional RMS)

Audio Connectors

ULTRA-X20/22/23 is available with XLR 5-pin, as shown in the first figure below, or 3-pin connectors shown in the second figure below, for audio Input and audio Loop output. XLR 5-pin connectors accommodate both balanced audio and RMS signals.

Note

• The 5-pin XLR connector option is not available for weather-protected models.

• Weather-protected models only are equipped with 3-pin XLR TOP (Total Outdoor Protection) connectors.

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 kΩ. The connector uses the following wiring scheme:

• Pin 1 — 1 kΩ to chassis and earth ground (ESD clamped)

• Pin 2 — Audio (+)

• Pin 3 — Audio (–)

• 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 kΩ, 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 the loudspeaker produces unwanted noise or hiss, 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 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). For applications that require multiple ULTRA-X20/22/23, 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 loudspeaker 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 Ω) to yield the maximum SPL over the operating bandwidth of the loudspeakers.

To calculate the load impedance for the looped loudspeakers, divide 10 kΩ (the input impedance for a single loudspeaker) by the number of looped loudspeakers. For example, the load impedance for 10 ULTRA-X20/22/23 is 1000 Ω (10 kΩ/ 10). To drive this number of looped loudspeakers, the source device should have an output impedance of 100 Ω or less. This same rule applies when looping ULTRA-X20/22/23 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 loudspeaker GALAXY Network Platform have an output impedance of 50 ohms. Each output can drive up to 20 Meyer Sound (10 kΩ) 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.

Weather-Protected Analog Audio Connectors

The weather-protected analog audio units are equipped with 3-pin XLR TOP connectors—a 3-pin female for the audio input and a 3-pin male for the audio loop.

Caution

• Always seal connectors (input or loop) with their attached sealing caps when not in use.

• This XLR TOP chassis connector is certified for outdoor protection only when used in combination with an XLR TOP cable connector or with the sealing cap in place when the chassis connector is not in use.

ULTRA-X20/22/23 Analog Version Limit and On/Status LED

Limiting

During normal operation, when ULTRA-X20/22/23 is powered on, the shared Limit and On/Status LED is solid green.

The low- and high-frequency drivers for ULTRA-X20/22/23 are powered by separate amplifier channels, each with their own limiter. Limiting activity is indicated by the Limit and On/Status LED illuminating yellow on the user panel. The LED, shown in the figure below, displays solid yellow for 1 second when the high-frequency channel limits and pulses yellow when the low-frequency channel limits.

ULTRA-X20/22/23 Analog Version Limit and On/Status LED

When limiting is engaged for a channel, its gain is reduced. The limiter protects the drivers and prevents signal peaks from causing excessive distortion in the amplifier, thereby preserving headroom and maintaining a smooth frequency response at high levels. When source levels return to normal below the limiter’s threshold, the LED turns green and limiting ceases.

The ULTRA-X20/22/23 performs within its acoustical specifications at normal temperatures when the Limit and On/Status LED is green, or when limiting is not continuous. During continuous limiting, the loudspeaker is nearing its operational limits, resulting in the following effects:

• Increases to the input level have no effect.

• Distortion increases due to clipping and nonlinear driver operation.

• The drivers are subjected to excessive heat and excur- sion, which compromises their life span and may eventu- ally damage them.

Caution

The Limit and On/Status LED indicates when a safe, optimum level is exceeded. If an ULTRA-X20/22/23 loudspeaker system begins to limit before reaching the desired SPL, consider adding more units to the system.

On/Status

During normal operation, when ULTRA-X20/22/23 is powered on, the Limit and On/Status LED is solid green.

ULTRA-X20/22/23 Limit and On/Status LED

If the loudspeaker encounters a hardware fault, or the unit 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, this situation may be verified in Compass RMS), a reduction in SPL may be necessary. If after a reduction in SPL and an appropriate cooling period the Limit and On/Status LED continues to flash red (does not return to solid green), contact Meyer Sound Technical Support.

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

Caution

If an ULTRA-X20/22/23 loudspeaker system consistently overheats before reaching the desired SPL, consider adding more units to the system.

Note

During startup, the Limit and On/Status LED flashes multiple colors successively.

Tip

When an ULTRA-X20/22/23 is connected to an RMS network, the Compass RMS software provides additional feedback about the loudspeaker’s hardware status and operating temperature (see RMS Remote Monitoring System).

The ULTRA-X20/22/23 Digital user panel (also referred to as the Type 3M Audio Input Module, shown in the figure below, includes an etherCON TOP (Total Outdoor Protection) for audio input, an Ethernet connectivity LED, an On/Status LED, and a Wink button/LED.

Remote Monitoring

ULTRA-X20/22/23 Digital loudspeakers include Meyer Sound remote monitoring functionality. No additional connections are required. When an ULTRA-X20/22/23 Digital loudspeaker and Compass computer are connected to the same network via an AVB-enabled network switch, the loudspeaker will appear under the Compass Control Software Inventory tab. The ULTRA-X20/22/23 Digital loudspeaker must be allocated to an available audio source channel (Talker) as a Listener.

Wink Function

Once the ULTRA-X20/22/23Digital has been configured into a network in Compass Control Software, the icons within the loudspeaker’s detail page include a W (Wink) icon. Pressing this icon will turn it green and cause the Wink push button of the associated loudspeaker to illuminate at the center

ULTRA-X20/22/23 Digital Audio Wink Push Button and LED

Conversely, if the Wink button on the ULTRA-X20/22/23Digital loudspeaker is pressed, a winking happy face is displayed on the associated loudspeaker page in Compass, as shown in the figure below.

Note

When pressed and released, the physical Wink button LED toggles between dark and solid green. When the Wink button is pressed and held, the On/Status LED will turn solid red. This is normal.

Result of Pressing Wink Button on Rear of Loudspeaker

These features facilitate matching of the physical loudspeaker to the Compass control software loudspeaker listings.

Ethernet/Network Connectivity LED

The Ethernet connectivity LED (Figure18, right) turns solid yellow when a 100Mb link is established; otherwise, it is off.

On/Status

During normal operation, when the ULTRA-X20/22/23 Digital is powered on, the On/Status LED is solid green.

The On/Status LED works in an identical manner to the analog version. It indicates limiting activity by turning yellow (see Limiting) and fault status with red (see On/ Status).

ULTRA-X20/22/23 On/Status LED and Ethernet LED (right)

Tip

When an ULTRA-X20/22/23 Digital and a computer running the Compass Control Software are connected to the same network, the Compass software provides additional feedback about the loudspeaker’s hardware status and operating temperature (see RMS Remote Monitoring System).

CONNECTING TO THE ULTRA-X20/22/23 DIGITAL VERSION

Help videos are also available at meyersound.com/videos.

AMPLIFIER COOLING SYSTEM

The ULTRA-X20/22/23 loudspeaker is convection cooled. The amplifier’s heat sink provides natural convection cooling from the air flowing near its fins.

Caution

• To keep ULTRA-X20/22/23 from overheating, allow at least 3 inches behind the loudspeaker for proper ventilation.

• The ULTRA-X20/22/23 heat sink can reach temperatures up to 80° C (176° F) during extreme operation. Wait 15 minutes for the unit to cool before touching.

ADDING LOW FREQUENCY CONTROL

An ULTRA-X20/22/23 loudspeaker system can be deployed with Meyer Sound self-powered low frequency control elements (see [→ _bookmark43]Table 4). These subwoofers achieve very low frequency responses and extend the system response appreciably, increasing the overall acoustic power of the system in the lowest frequencies.

The ideal ratio of ULTRA-X20/22/23 loudspeakers to low frequency control element depends on the following variables:

• Subwoofer model

• System configuration

• Frequency content of source material

• Headroom required for low frequencies

For most applications, the ratios in [→ _bookmark43]Table 4 should yield good results.

Table 4. Recommended Meyer Sound Subwoofer

Subwoofer	Frequency Response	Recommended Ratio (Number of ULTRA-X20/22/23s per Subwoofer)
USW-112P	36–125 Hz ±4 dB	1:1 for most applications
USW-210P	32–123 Hz ±4 dB	1:1 for most applications 1:2 for applications requiring more low end
750-LFC	37–110 Hz ±4 dB	1:1 for most applications
900-LFC	32–115 Hz ±4 dB	2:1 for most applications 1:1 for applications requiring extreme low end

ADDING SUBWOOFERS BY DAISY-CHAINING

Full-range signals can be connected directly to Meyer Sound self-powered loudspeakers because the loudspeakers have built-in active crossovers. Subwoofers can be added to an ULTRA-X20/22/23 system by simply daisy-chaining them to the ULTRA-X20/22/23 loudspeakers.

To daisy-chain the suggested number of ULTRA-X20/22/23 loudspeakers for your subwoofer (see Table 1).

1. Connect the source signal to the Input of the first ULTRA-X20/22/23, then connect the Loop output of the first ULTRA-X20/22/23 to the Input of the second ULTRA-X20/22/23 (and so forth).

2. Connect the Loop output of the last ULTRA-X20/22/23 in the chain to the subwoofer Input.

When ULTRA-X20/22/23 loudspeakers are coplanar, or they are very close together, about four to six feet like in the case of pole mounting, the phase response will work well in the area of interaction and the result will be a fairly flat frequency response. However, the response will show an increase in the 60–200 Hz range where the response of the loudspeakers overlaps.

Note

If the subwoofer’s Limit LEDs begin to light before reaching the required SPL, consider adding more subwoofers to meet the SPL requirements without exposing the drivers to excessive heat and excursion.

USING A PROCESSOR

In larger systems when individual control for the ULTRA-X20/22/23 and subwoofers are needed or desired, if the ULTRA-X20/22/23 loudspeakers and subwoofer are more than six feet apart, or if a delay is required between them, use a measurement system to determine appropriate delay and polarity settings.

Caution

Make sure the source signal is sufficient to drive the total load impedance of the daisy-chained loudspeakers (see Audio Loop Output (XLR 3-Pin or 5-Pin Male)).

Tip

MAPP can be used to accurately predict the appropriate loudspeaker deployment and subwoofer integration for loudspeaker systems, complete with coverage data, system delay and equalization settings, rigging information, and detailed design illustrations. For more information, see MAPP System Design Tool.

The ULTRA-X20, ULTRA-X22 AND ULTRA-X23 loudspeakers are compatible with Meyer Sound’s QuickFly system, a comprehensive collection of custom-designed rigging, flying, and mounting options. Comprised of rugged, reliable, and easy-to-configure components, QuickFly enables deployment of ULTRA-X20/22/23 loudspeakers as either individual loudspeakers or as two-speaker clusters at precise angles to take full advantage of their directional components.

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

The top and bottom aluminum plates for the ULTRA-X20/22/23 cabinet include rigging points that provide two M8 x 1.25 threaded holes (on each end) for easy connection to QuickFly rigging and third-party mounting options.

ULTRA-X20/22/23 Rigging Points

Meyer Sound offers a number of rigging options that facilitate a wide variety of configurations, as described in the table below.

The ULTRA-X20 loudspeaker can be suspended simply by using one or two M8 eye bolts. The use of two eye bolts provides the added flexibility of aiming and tilting the loudspeaker for targeted coverage.

ULTRA-X20 with One Eye Bolt

The MPK-POLE-35MM-M20 (PN40.010.973.01) provides an easy and efficient way to mount the ULTRA-X20/22/23 on top of a USW-112P, 750-LFC or 900-LFC. The MPK-POLE-35MM-M20 features all steel shafts that telescope from 36.5–60inches and employs a secure knob to hold it in a specific position. The upper shaft includes the removable PAS-M20-35MM with M20 Slug Adapter Sleeve as well as the PAS-M8 Adapter Sleeve.

MPK-POLE kit

The MPK-POLE features a lift assist that provides approximately 40 lb of internal gas cylinder pneumatic lift. The lower end of the pole is 35 mm in diameter and has an M20 threaded lug for stability that can be removed if necessary. In addition, the MPK-POLE-35MM-M20 kit includes an adapter for converting the bottom diameter from 35 mm to 38 mm.

The pole can be used without the lug for loudspeakers that have 35 mm cup mounts without M20 threads, or the 35 mm to 38 mm adapter may be slipped onto the bottom for loudspeakers that have 38 mm cups, as shown in the figure below.

Pole with 35 mm to 38 mm Adapter Sleeve Attached

Meyer Sound recommends that a 750-LFC (or 900-LFC) be upgraded with the 35 mm/M20 internal pole mount cup (PN 40.271.016.02) for a more stable connection, as shown in the figure below. This part is included with the MPK-POLE kit.

35 mm/M20 Internal Pole Mount Cup (PN 40.271.016.02)

The PAS-M8 Adapter is designed to securely fit into an M8 rig nut on the bottom of the ULTRA-X20/22/23. The separate knob on the adapter tightens it to the pole. (It can also be secured onto any other standard 35 mm pole.)

The PAS-M8 may be independently (apart from the pole) threaded into the ULTRA-X20/22/23, as shown in the first figure below, and then the loudspeaker/PAS-M8-35MM Adapter combination mounted onto a pole that is already secured in the subwoofer, as shown in the second figure below. The loudspeaker may be aimed horizontally, and the PAS-M8 knob tightened.

Inserting the PAS-M8 Adapter Sleeve Independently

Settling Loudspeaker/Adapter Combination onto Pole

The MYA-X20 mounting yoke (PN 40.297.450.01) suspends a single ULTRA-X20/22/23 loudspeaker and supports a wide range of horizontal and vertical adjustments. The yoke attaches to the top and bottom of the loudspeaker using the top and bottom center M8 threaded hole, shown in the second figure below. The kit includes two M8 bolts/washers and two M8 knobs/washers. The bolts are recommended for fixed installations. A hanging clamp and steel safety cable (not included) are required to suspend the MYA-X20 mounting yoke.

MYA-X20 Mounting Yoke

The MUB-X20 U-Bracket (PN 40.297.454.01) allows a single ULTRA-X20/22/23 loudspeaker to be mounted on walls, ceilings, trusses and stage lips. The U-bracket’s adjustment slots allow for adjustment on how close the loudspeaker is located to the mounting surface and at what angle it will be positioned. The MUB-X20 kit includes two M8 bolts with washers and two M8 knobs with washers. The bolts are recommended for fixed installations.

MUB-X20 U-Bracket

One ULTRA-X20 can be safely be mounted with the MUB-X20 U-bracket at a 5:1 safety factor. When mounting an ULTRA-X20 with the MUB-X20 U-bracket, the U-bracket must be secured to the mounting surface with one of the configurations indicated in the table below.

The versatile configuration of the channel and link, with the ability to slide the pinnable link within the channel, facilitates 13 different top pickup points. This flexibility allows for approximately +11° to –22° tilting of a loudspeaker that hangs from a single point, as described in the table below.

MTC-X20 Pickup Points

Using three versions of this kit allows the user to create a two-loudspeaker configuration with an angle of 50° between top and bottom speakers, as shown in the figure below.

The MAPP System Design Tool is a powerful, cross-platform application for accurately predicting the coverage pattern, frequency response, phase response, impulse response, and SPL capability of individual or arrayed Meyer Sound loudspeakers.

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 intended, thereby eliminating unexpected coverage problems and minimizing onsite adjustments.

The key to the accuracy of MAPP’s predictions is MeyerSound’s exhaustive database of loudspeaker measurements. Performance predictions for each loudspeaker are based on 3-dimensional, 65,000+ 1/48th-octave-band measurements taken in the MeyerSound anechoic chamber. The extraordinary consistency between Meyer Sound loudspeakers guarantees that predictions from MAPP will closely match their actual performance.

MAPP software allows for configuration of MeyerSound loudspeaker systems and definition of the environment in which they operate, including air temperature, pressure, humidity, and the location of prediction surfaces. Importing both CAD (.DXF) and Sketchup (.SKP) files containing detailed venue information to act as an anchor model to the prediction surfaces and a visual aid to facilitate prediction data interpretation is also possible.

MAPP Capabilities

With MAPP, you 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 MeyerSound 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. 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. See www.meyersound.com to locate their datasheets for more information.

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.
