The 750-LFC cabinet's front and middle links insert into slots in

loudspeaker's middle GuideALinks when flying
the 750-LFC below the MG-MINA/LINA/750-LFC
grid or when flying below another 750-LFC. Always use
the front and rear GuideALinks when flying the
750-LFC.
750-LFC Splay Angles
The front and rear GuideALinks attach at angles of 0°, 1.5°, 3.25°
or 4.75°, allowing for curved 750-LFC arrays. Because the
cabinet's front and rear GuideALinks are symmetrical, the
curved arrays can also include cardioid configurations.
Figure 22: 750-LFC Front GuideALinks Label
The labels next to the front and rear GuideALinks indicate the
splay angle between cabinets (when the opposing links are set
to 0°). As the links are moved down, the splay angle increases.
To stow the GuideALinks, move them all the way up to STOW
and pin them.
NOTE: Curved 750-LFC arrays do not provide
directionality for low-frequency content. The
curved array capability of the 750-LFC is provided
