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. Tighten the bolts securely.
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 is
limited by the end of the speaker encountering the wall. The maximum swivel angle depends on:
a) which of the speaker’s rear-panel positions the
SPEAKER BRACKET
is mounted to, and b) the
down-tilt angle setting.
The following chart 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.

**
The very top bracket position and 15° tilt angle interferes with wall even with no swivel angle.
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 100LA/50LA-1 cabinet using one of the extra included M6 mm bolts. 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.
