Preparing the AMT-Series Yoke Kit for
Assembly with the AMT Loudspeaker

AFTER FIRST SECURELY ATTACHING THE
YOKE to a mounting surface (see section 3),
the loudspeaker can be attached to the yoke.
This is best accomplished with two people,
one to hold the loudspeaker in place, the
other to insert the hardware (bolts, washers,
spacers). The bolt, flat steel washer, steel
spacer, and rubber washer need to be used
on each end of the cabinet (top & bottom) to
securely hold the loudspeaker in place.

Remove Feet from AMT Speaker

If the enclosure will be pivoted more than
a few inches to the left or right / up or down,
remove the 4 feet from the bottom of the
enclosure. This will allow the speaker to
rotate fully. When the desired angle has
been set, fully tighten both the top and
bottom socket head screws.

Holding the loudspeaker in place, line up the holes in the yoke with the holes in
the top and bottom of the enclosure closest to the front of the cabinet. The first
bolt/washer/spacer/rubber washer combination needs to be installed in the correct
order (see Diagram A) on one end of the bracket and speaker, then can be partially
tightened. The second bolt/washer/spacer/rubber washer combination can then
be installed at the other end of the bracket and speaker and partially tightened.
Once the desired orientation of the speaker is selected, the bolts can be fully
tightened to prevent the enclosure from pivoting.

This attaches to the rear thread/rigging
point in the top of the speaker using
the supplied low profile socket head
bolt with the lock washer. The attached
bracket can now be rotated to the most
convenient angle for attaching a safety
cable (cable to be user supplied).
