A. Loosen and remove the molded nut (2) by turning it counter
clockwise. Use the supplied metal bar (5) if necessary by inserting
it in one of the holes on the molded nut (2).
B. Pull the ball/shaft (3) out of the wall bracket (4).
C. Slide on the molded nut (2) onto the ball/shaft (3) with threaded
opening facing the ball, and thread on the metal nut (1) all the way
onto the ball/shaft (3), with the nut's (1) "knurled" surface facing
away from the ball.
D. Screw on the ball/shaft (3) into the threaded 1/4"-20 insert on the
back of the speaker cabinet (6) until it is fully seated against the
bottom of the insert. Back out the ball-shaft assembly 1/2 of a
turn and tighten the nut against the speaker. If the ball and shaft
assembly is not backed out before tightening the nut, performing
Step G below may dislodge the threaded insert in the speaker
housing and permanently damage the speaker.
E. Tighten the "knurled" nut (1) using a crescent wrench until it is
firmly seated against the back of the speaker and has fully locked
the ball/shaft (3) and the speaker cabinet together. Pleace note that
once this nut is tightened, it may embed some marks on the back of
the speaker where the attachment is made. However, these marks
will be covered by the nut (1).
F. The back-up cord (8) is provided as an additional measure to
prevent the fall of the speaker in case the speaker becomes
detached from the wall bracket.
One of the two lower screws (9) that attach the wall bracket (4) to
the wall will need to go through the eyelet (11) at the end of the cord
before going through the wall bracket hole. Mount the wall bracket
(4) onto a wood stud on the wall, using #10, minimum 1-inch-long,
panhead wood screws. Make sure that all 4 screws are driven into
the stud, not drywall. If the bracket needs to be mounted on drywall,
the use of properly selected and installed wall-anchors and screws
is essential. Make sure that the screw head is at least 0.36 of an
inches (approximately 3/8 of an inches) or larger in diameter so that it
can properly hold the backup cord eyelet (11).
G. Holding the speaker cabinet (7) with both hands, reinsert the ball
portion of the ball/shaft (3) into the wall bracket (4).
H. Hand-tighten the molded nut (2) while positioning the speaker for
the intended orientation.
I. Once the orientation of the speaker is finalized, use the metal bar
(5) in one of the holes on the molded nut (2) and tighten securely.
J. Securely attach the other end (10) of the backup cord (8) to the
Control 2.4G, by engaging it through the bar (12) on the back
speaker.
Also included with the system is a wall-mount holder for the active
speaker's power supply. If desired, you may attach this holder to the
wall and insert the speaker's power supply.
