LYON OPERATING INSTRUCTIONS
LYON GUIDEALINKS
LYON is equipped with four captive GuideALinks and four
mating link slots that link to adjacent units in flown arrays.
Located at the top corners of the cabinet, GuideALinks
extend up and into the link slots of the cabinet above it, or into
the link slots of the MTG-LYON grid, making it easy to link
cabinets once they are stacked (Figure 14 and Figure 15).
GuideALinks extend and retract with knobs and are secured
with two quick-release pins: one each in the top and bottom
cabinets. Each LYON loudspeaker ships with 10
7/16 x 0.90-inch quick-release pins (black button)
(PN 134.050).

CAUTION:
GuideALinks must be secured with
the included quick-release pins. At no time
should the weight of the loudspeaker rest on the
GuideALink knobs when the links are fully extended
(without the pins inserted). GuideALink knobs are for
extending and retracting the links only.
LYON Splay Angles
Rear GuideALinks attach at a fixed splay angle of 0 degrees
and act as a pivot point between linked LYONs, with the splay
angle between the units determined by the front GuideALink
22
positions. Rear GuideALinks can be pinned in either of two
positions: extended or stowed.
Figure 15: LYON GuideALinks (Exposed) Attached at 0 Degrees
Front GuideALinks determine the loudspeaker splay angles
and are configured with the yellow ANGLE positions when the
cabinets are resting in the caster frame (Figure 16). After the
stack is lifted with the motors, the loudspeakers rotate on the
axis of the rear GuideALinks and the front GuideALinks slide
into position as the weight of the loudspeakers causes the
cabinets to shift, at which point, quick-release pins are
inserted in the corresponding blue LOCKING positions to lock
the splay angles.
Available splay angles for linked LYONs include 0.0, 0.5, 1.0,
1.5, 2.0, 3.0, 4.0, 5.0, 7.0, and 9.0 degrees and are indicated
by the blue and yellow GuideALink labels.
CAUTION:
Splay angles of 0 degrees should
only be used for the top cabinet attached to
the grid. Splay angles of at least 0.5 degrees are
recommended for cabinets near the top of the array.
If multiple cabinets are set to 0 degrees and the array
is flown with downtilt, the resulting splay angles could
be negative because of the gaps in the links and pins
that facilitate easy pinning.
