SPEAKER ORIENTATION

CORRECT

The A12 Armadillo Loudspeaker is acoustically designed to operate in a vertical
orientation. This orientation will provide 90 degrees of horizontal coverage and
45 degrees of vertical coverage.

WRONG

The A12 is a ported speaker, designed to shed water, and includes a unique water­repellent scrim. This scrim covers the ports and horn throat to slow the ingress of
water, but a small amount of water may still enter the cabinet. Weep holes are pro­vided at the bottom of the speaker baffle to drain any water that enters the cabinet.

NOTE: It is very important that the speaker be mounted with its face either vertical
or facing down. Never install the speaker with the face tilted up, as this will under­mine the water-shedding aspects of the design and allow excessive water to enter
the cabinet.

YOKE INSTALLATION

After selecting the speaker location, securely attach the yoke to the surface. An
Adjustable Tilt-Mount Adapter (TMA812) is available to provide various tilt angles.
The TMA812 allows attachment to walls and posts.

WARNING: Mounting brackets must be secured in accordance with local codes.
If in doubt, consult a professional contractor to determine the integrity of the struc­ture to which the bracket will be attached. When required, a safety cable can be
secured to the back of the speaker using the threaded brass insert on the back of
the speaker housing and the forged steel safety bolt (included).

MOUNTING THE SPEAKER ON THE YOKE

The A12 yoke allows the speaker to be
slipped onto it with the locking knobs
attached. First, both knobs need to be
removed and the supplied rubber friction
disks applied to the speaker enclosure
where the knobs clamp. Do not apply the
friction disks directly to the mounting
knobs. Next, screw the knobs back onto
the enclosure about two turns and simply
slide the knob shafts down the slots in the
yoke. Now tighten the knobs making sure
that the shoulder of the knob seats
properly through the large hole at the end
of the yoke.

SOME FACTORS TO CONSIDER

Distance is not the only factor affecting sound intensity. Also consider what adjacent
surfaces may affect the sound (including but not limited to buildings, walls, and
overhangs). These structures may provide positive effects (low frequency
reinforcement) or negative effects (high-frequency reflections that will degrade
intelligibility).
