CHAPTER 4: QUICKFLY RIGGING

NOTE: To achieve an accurate cardioid pattern,
you must use Meyer Sound’s MAPP prediction
software. Use MAPP to calculate the appropriate
ratio of forward- to rear-facing loudspeakers, as well as
the processor settings for polarity. A myriad of possible
cardioid and directional configurations can be calculated
and predicted with MAPP. For more information, contact
Meyer Sound Technical Support.
MRK-750 RIGGING KIT
The optional MRK-750 rigging kit allows the 750-LFC
loudspeaker to be flown and groundstacked with the
MG-MINA/LINA/750-LFC multipurpose grid. The kit also allows
750-LFC loudspeakers to be flown and groundstacked with
LINA loudspeakers 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.
NOTE: For more information about the MRK-750
rigging kit, including its kit contents, weight, and
installation instructions, refer to the
MG-MINA/LINA/750-LFC Assembly Guide
(PN 05.207.101.02) available at
meyersound.com/documents
.
750-LFC GUIDEALINKS
When equipped with the MRK-750 rigging kit, the 750-LFC
cabinet 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. GuideALinks
extend and retract with knobs and are secured with two quick-
release pins: one each in the top and bottom cabinets.
GuideALinks accommodate reversed units for cardioid arrays.
The MRK-750 rigging kit includes ten loudspeaker quick-
release pins (0.25 in x 0.53 in, black button, PN 134.039
).
