  • Page 9: Chapter 1: Introduction

    Load Ratings and Specifications Long-term safe operation is a central concern in the design and manufacture of any rigging/flying system. Meyer Sound has taken great care in material selection and component design. In all critical cases, load points are redundant, with a safety margin that allows one or more load points to fail while maintaining system integrity.
  • Page 10 GINS FOR THE SYSTEM COMPONENTS SUSPENDED BELOW THEM. Inspection and Maintenance The Meyer Sound QuickFly systems are an assembly of mechanical devices, and are therefore subject to wear and tear over prolonged use, as well as damage from corrosive agents, extreme impact, or inappropriate use.

  • Page 11: Lina And 750-Lfc Rigging Options

    QuickFly systems are identical to those used in other rigging applications. To the best of our knowledge, most of these suppliers are reputable and their products are reliable. However, Meyer Sound has no way of assuring the quality of products made by these various suppliers.

The kit also allows 750-LFCs to be flown and groundstacked with LINA with no transition hardware. The rigging kit is available as a factory-installed option or as a field upgrade and uses rugged GuideALinks and intuitive quick- release pins to securely link adjacent loudspeakers in flown and groundstacked array configurations.

    CHAPTER 3: 750-LFC GROUNDSTACKS AND CARDIOID ARRAYS GROUNDSTACKING 750-LFC LOUDSPEAKERS (WITHOUT GRID) 750-LFCs can be groundstacked up to three units high, with or without the MRK-750 rigging kit. Protective plastic skids that align with the slots on the cabinet top are included on the bottom of the 750-LFC cabinet. Units can be stacked normally or reversed for cardioid configurations.

  • Page 20: 750-Lfc Cardioid Arrays

    NOTE: information, see Chapter 5, “MG-MINA/LINA/750-LFC Grid.” To achieve an accurate cardioid pattern, you must use Meyer Sound’s MAPP prediction software. Use NOTE: MAPP to calculate the appropriate ratio of forward- to rear-facing loudspeakers, as well as the processor set- tings for polarity.

  • Page 21: Chapter 4: Loudspeaker Guidealinks

    CHAPTER 4: LOUDSPEAKER GUIDEALINKS LINA loudspeakers are compatible with Meyer Sound’s QuickFly rigging system, a comprehensive collection of rigging, fly- ® ing, and mounting hardware. LINA’s captive GuideALinks allow cabinets to be linked at various splay angles for flying, groundstacking, and transport. The heavy-duty GuideALinks allow for easy adjustment of array tilts, eliminating the need for pull-back straps in flown configurations.
  • Page 22 CHAPTER 4: LOUDSPEAKER GUIDEALINKS Front GuideALinks The front GuideALinks act as a pivot point between linked LINAs, with the splay angle between the units determined by the rear GuideALink positions. When stowing front GuideALinks, the knob is positioned at the top of the slot. knob Figure 7: LINA Front GuideALinks Rear GuideALinks...
  • Page 23 MG-MINA/LINA/750-LFC GRID ASSEMBLY GUIDE The label in the lower rear corner of the end frame shows the splay angle between LINAs given a GuideALink pinning posi- tion. With the knob at the bottom, the splay angle is 0 degrees. As the knob is moved up, the angle increases (all the way to 11 degrees).
  • Page 24 CHAPTER 4: LOUDSPEAKER GUIDEALINKS For Ultra-weatherized versions of the LINA (see “ULTRA Weather Protection Version” on page 83), the NOTE: 11° position is not available. The splay angles listed on the GuideALink label are for relative angles between the center axes of the NOTE: linked units.

    MG-MINA/LINA/750-LFC GRID ASSEMBLY GUIDE 750-LFC GUIDEALINKS When equipped with the MRK-750 rigging kit, the 750-LFC includes six captive GuideALinks and six mating link slots that link to adjacent units in flown and groundstacked arrays. Located at the bottom of the cabinet, GuideALinks drop down and into the link slots of the cabinet below it.

    MAPP is a powerful, cross-platform 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 client allows configuration of Meyer Sound loudspeaker systems and definition of the environment in which they will operate, including air temperature, pressure, and humidity.
  • Page 39 MAPP download link. On-screen instructions will provide guidance for the download and installation process. The MAPP client software is regularly upgraded to add support for the latest Meyer Sound loudspeakers and to add feature enhancements. The MAPP database includes nearly all of the current Meyer Sound loudspeakers, subwoofers, and proces- sors.
  • Page 40 CHAPTER 6: FLYING ARRAYS 4. If necessary, adjust the MG-MINA/LINA/750-LFC grid height and grid angle to meet the system’s acoustical require- ments. These properties can be adjusted by entering values in the Edit Flown Loudspeaker Properties dialog box (select Edit and scroll down to Edit Flown Loudspeaker Properties to bring up dialog box), or by manually dragging the grid with the Select and Rotate tools in the Sound Field.
