750-LFC OPERATING INSTRUCTIONS
10
NOTE: To guarantee optimum performance,
use Meyer Sound’s MAPP software to design
systems with the 750
-
LFC.
The 750
-
LFC is available with or without Meyer Sound’s
QuickFly
®
rigging. When equipped with the optional MRK
-
750
rigging kit, the 750
-
LFC cabinet’s captive GuideALinks allow
it to be flown from the MG-MINA/LINA/750-LFC multipurpose
grid in LINA/750-LFC arrays without any transition frame
between the 750
-
LFC and LINA loudspeakers (Figure 2, left).
The MG
-
MINA/LINA/750
-
LFC grid can also be used to create
a wider base for groundstacks (Figure 2, right).
750
-
LFC loudspeakers can be flown separately as a
subwoofer array with variable splay angles from 0° to 5°. It is
also possible to configure the 750-LFC loudspeaker in
cardioid arrays to reduce output behind the loudspeakers.
Optional MCF-750 caster frames are available for
transporting the 750
-
LFC loudspeaker in stacks. The caster
frame comes in two versions (for loudspeakers equipped with
the rigging kit or not). Please specify the appropriate caster
frame version when placing an order.
The 750-LFC integral pole-mount facilitates placement of one
or two LINA loudspeakers on top of a pole using the
MUB
-
LINA (Figure 3) or MYA
-
LINA yoke. In addition, the pole
mount can be used to pair the 750
-
LFC with the ULTRA-X40
and other UltraSeries loudspeakers.
NATIVE MODE
LINA and 750
-
LFC loudspeakers are optimized for use in
certain flown and groundstacked configurations without any
array compensation or other signal processing. This
capability, called
Native mode , allows LINA/750
-
LFC systems
to be deployed quickly with excellent results, without
equalization, tuning, or use of presets.
To use LINA and 750
-
LFC loudspeakers in Native mode, send
an identical, unmodified signal to each element in the array.
The simplest method is by looping the same, unprocessed
source signal through all array elements.
The following coplanar configurations can be used in Native
mode (without any signal processing):
•
Flown mixed arrays of LINA and 750
-
LFC loudspeakers
(Figure 4)
•
Flown separate arrays of LINA and 750
-
LFC
loudspeakers (Figure 5)
•
Mixed groundstacks of LINA and 750
-
LFC loudspeakers
(Figure 2, right and Figure 6)
•
LINA or ULTRA-X40 loudspeakers pole-mounted on top
of a 750-LFC loudspeaker (Figure 3 and Figure 7)
In addition, 750-LFC and ULTRA-X40 loudspeakers are
optimized for use together in groundstacked configurations
without any array compensation or other signal processing.
