1 INTRODUCTION These operating instructions provide important information about the form, features, function, and specifications of the M’elodie TM ultracompact high-power curvilinear array loudspeaker .
2 INTRODUCTION.
3 CHAPTER 1 The self-powered M’elodie ultracompact high-power curvilinear array loudspeaker is a member of the popular MILO ® family of loudspeakers. Its extended high-frequency headroom gives it a smooth sound over its wide operating frequency range of 70 Hz to 18 kHz.
4 CHAPTER 1 Figure 1.2. M’elodie amplifier This modular , field-replaceable amplifier/processing package also incorporates Meyer Sound’ s Intelligent AC™ power supply , which automatically adjusts for any line voltage worldwide and provides both soft turn-on and transient protection.
5 CHAPTER 1 Figure 1.4. Ground-stacked M’elodie cabinets The MCF-M’elodie caster frame is designed for transporting stacks of multiple units and facilitate the use of forklifts. A range of rugged protective transport covers is available. M’elodie is also truck-smart.
6 CHAPTER 1 Figure 1.7. The 600-HP high-power subwoofer M’elodie is supported by Meyer Sound’ s MAPP Online Pro acoustical pr ediction program and the Galileo™ loudspeaker management system. Once a M’elodie system is designed and installed, its performance can be confirmed using a SIM 3 audio analyzer system.
7 CHAPTER 2 Self-powered and ultracompact, M’elodie combines advanced loudspeaker technology with equally advanced power capabilities. Understanding the loudspeaker’ s power distribution, voltage, and current r equirements, as well as electrical safety issues, is critical to the safe and correct operation and deployment of M’elodie.
8 CHAPTER 2 The blue connector serves as the input for all the units looped in that circuit and it is rated to 20 amps maximum. Please make sure never to exceed 20 amps on any single connector .
9 CHAPTER 2 TIP: Since M’elodie does not requir e a dedi- cated neutral, it can tolerate elevated volt- ages from gr ound and can be connected between line-line terminals in a 120 V 3-phase Wye system.
10 CHAPTER 2 NOTE: For best performance, the AC cable voltage drop should not exceed 10 volts, or 10 percent at 115 volts and 5 per cent at 230 volts. Make sure that even with the AC voltage dr op, the AC voltage always stays in the operating windows.
11 CHAPTER 3 More than just a self-power ed loudspeaker , M’elodie uses sophisticated amplification and protection cir cuitry and an advanced limiting system to produce consistent and predictable r esults in any system design.
12 CHAPTER 3 NOTE: For details on the M’elodie loud- speaker’ s audio input characteristics and amplification, see Appendix C. AMPLIFICA TION AND PROTECTION CIRCUITRY M’elodie is powered by Meyer Sound MP-1/M’elodie ampli- fier modules in a three-channel amplifier configuration with a total power of 1275 watts (2550 watts peak).
13 CHAPTER 3 M’elodie is performing within its acoustical specifications and operating at a normal temperature if the limit LEDs ar e lit for no longer than two seconds, and then go off for at least one second.
14 CHAPTER 3.
15 CHAPTER 4 RMS is a real-time monitoring system that connects Meyer Sound self-powered loudspeakers with a Windows-based PC at the sound mix position or other location. Optional RMS software delivers extensive status and system perfor - mance data from every installed loudspeaker .
16 CHAPTER 4 Service LED (Red) The Service LED blinks every two seconds to indicate that the network hardwar e is operational, but the loudspeaker is not installed (commissioned) on the network.
17 CHAPTER 5 HOW LINE ARRA YS WORK Line arrays achieve directivity thr ough constructive and destructive interference. For example, consider one loudspeaker with a single 12-inch cone radiator in an enclosure.
18 CHAPTER 5 Figure 5.1. MAPP Online Pro predictions of 6-, 12-, and 18-cabinet M’elodie line arrays at 125 Hz (top) and 250 Hz shows how directionality increases with length of array .
19 CHAPTER 5 Low-Frequency Design Strategies While wave guides provide isolated contr ol over various mid- to high-frequency coverage ar eas, the low-frequency section of a M’elodie array still requir es mutual coupling — with equal amplitude and phase — to achieve better directionality .
20 CHAPTER 5 The block diagram below (Figure 5.3) shows one method of driving this example array , along with subwoofers (not in the MAPP Online Pro pr edictions). CAUTION: This example is not meant to be used as a template for your own system designs.
21 CHAPTER 5 Using Meyer Sound Processors to Drive and Optimize the Array The Galileo 616 loudspeaker management system and the LD-3 compensating line driver are specifically designed to allow you to follow these optimization strategies: ■ The array can be divided in zones.
22 CHAPTER 5 NOTE: When p re cise a rray d esign, subwo ofer integr ation, DSP a nd del ay sys tems, and compen sation for a cousti cal co nditio ns all come into play , measur eme nt and corr ecti on too ls ar e a must.

25 CHAPTER 7 M’elodie loudspeakers feature Meyer Sound’ s QuickFly rigging system with rugged, reliable and simple components. QuickFly facilitates deploying the loudspeakers in a variety of applications.
26 CHAPTER 7 The rear GuideALinks permit 12 splay angles between 0 and 11 degrees in 1-degr ee increments. The GuideALink has four rows each with 3 columns. The splay angle between cabinets increases by one degr ee as the GuideAlink is pinned in adjacent positions from fr ont to back and top to bottom.

29 CHAPTER 7 CAUTION: Do not exceed five M’elodie cabinets high to avoid tipping over the stack. CAUTION: Avoid moving the M’elodie stack in the front-to-back dir ection of the loudspeakers (the long side); always move the stack sideways to avoid tipping it over .
30 CHAPTER 7 Figure 7.15. T ransporting M’elodie enclosures with the MG-M’elodie installed on the top of the stack CAUTION: When using the MCF-M’elodie caster frame to ground-stack M’elodie loudspeakers, make sure all four caster wheels ar e blocked to prevent the stack fr om rolling away .
31 APPENDIX A In weather -protected versions, a rain hood is included to safeguard the user panel and connectors fr om the elements. INST ALLING THE M’ELODIE QUICK-CLIP RAIN HOOD 1. Check the rain hood to assure that the gasket material is firmly attached along all the inner edges.
32 APPENDIX B The M’elodie loudspeaker requir es a grounded outlet. It is very important that the system be properly gr ounded in order to operate safely and pr operly .
