PACKAGE CONTENTS
SPEAKER ORIENTATION
RIGHT
The NEAR A12 is acoustically designed to operate in a vertical orientation with the NEAR logo right side up. This orientation will provide 90 degrees of hori­zontal coverage and 45 degrees of vertical coverage.
RIGHT
WRONG
The A12 is a ported speaker, designed to shed water, and includes a unique water-repellent 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.
WRONG
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 an- gles. 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).
