hardware. For the CBT 70J-1 there are three (3) possible mounting positions. Choose the one
that best suits the application. Be sure the hook feature is downward.

SET THE TILT ANGLE
– Once the speaker has nested securely on the pivot bolt, slide the second
M6-60L bolt into one of the holes in top of the wall bracket to set the angle.
5a) TILT ANGLES
5b) PRE- SET ANGLES and CONTINUOUSLY VARIABLE ANGLE
-- The bracket allows for +/-15 degrees of tilt.
-- The bracket has through
holes for mounting angles of +/- 15 degrees in 5 degree increments. There is also a slot above the
holes for continuously variable adjustment. The pre-set angles are recommended for accurate
aiming.
5C) SECURE THE ANGLE SETTING
with hardware provided.
-- Once the angle has been chosen re- tighten both bolts

SET THE SWIVEL (PAN) ANGLE
– Loosen the top and bottom bolts on the pivot. Adjust the
side-to-side swivel (ie, pan) aiming angle of the speaker. Re-tighten the bolts securely at desired
swivel (pan) angle.
Maximum Swivel Angles before Wall Interference
– The bracket swivels a full 90 degrees from
side-to-side, however when mounting the CBT speaker onto a wall, the side-to-side swivel may be
limited by the end of the speaker encountering the wall. The maximum swivel angle depends on:
a) which of the rear-panel insert points on the speaker the SPEAKER BRACKET is mounted onto,
and b) the down-tilt angle setting.
The following charts lists the typical maximum side-to-side swivel angles for some of the possible
Speaker Bracket mounting point locations, and for 0°, 5°, 10°, and 15° down-tilt angle settings.
(For the combination CBT 70J-1+70JE-1 array, the only recommended mounting point for the
SPEAKER BRACKET
is on the Coupler Plate, so that is the only mounting point shown in the
chart for the array.)

Maximum Swivel Angles in Other Mounting Situations
– The bracket itself can swivel up to 90
degrees (side-to-side), so if the speaker is being mounted onto a pole or an outside corne r, for
example, where interference with a wall may not be a factor, then greater swivel angles than those
stated in the above chart may be achieved.
7)
SAFETY CABLE --
Attach a safety cable (not included) to any of the 6 mm inserts on the back of
the CBT 70J and/or 70JE cabinet using the included M6-15L mm bolt. Prepare to attach the other
end of the cable to a secondary attachment point on the wall.
8)
SWITCH COVERS –
To discourage tampering with the switch settings, adhesive switch covers are
provided. Peel off the backing from the switch cover and stick the cover over the switch shaft,
lining up the ridge with the recess in the switch shaft.
