CBT 50LA-1 & CBT 100LA-1 Bracket Installation Guide Rev B – For Swivel (Pan) / Tilt Wall Bracket Included: SPEAKER BRACKET M6-34L SWIVEL-TILT WALL BRACKET M6-15L M6 nuts SS Lock washers CBT 100LA-1 CBT 50LA-1 SS Flat washers switch covers CBT 50LA-1 & CBT 100LA-1 Bracket Installation Guide – Page 2 WALL SURFACE MOUNTING Note that the BRACKET ASSEMBLY consists of a SPEAKER BRACKET and a WALL BRACKET. 1) RUN WIRING -- Run the wiring from the power amplifier to the location desired for mounting the JBL CBT Loudspeakers. 2) ATTACH WALL BRACKET TO WALL -- Using a level to ensure that the WALL BRACKET is straight, secure the WALL BRACKET to the wall. Be sure to use the appropriate wall anchors for attaching the bracket. Use all four screw holes for maximum integrity and safety. Be sure that the slot feature is at the top. Hardware for attaching WALL BRACKET to wall not included. CBT 50LA-1 & CBT 100LA-1 Bracket Installation Guide – Page 3 3) ATTACH SPEAKER BRACKET TO SPEAKER 3a) CBT 50LA-1 -- Mount the SPEAKER BRACKET to the speaker with the provided M6-15L pan head bolts, lock washers and flat washers, as shown below.

For tilt and swivel (pan) angles before wall interference, see “Maximum Swivel Angle Before Wall Interference” chart, later in this guide. CBT 50LA-1 & CBT 100LA-1 Bracket Installation Guide – Page 5 4) SLIDE SPEAKER WITH SPEAKER BRACKET ONTO WALL BRACKET -- Once the wall mount has been attached to the wall and speaker mount has been attached to the speaker, slide the speaker forward so that the SPEAKER BRACKET engages into the WALL BRACKET, dropping the hook slot of the SPEAKER BRACKET onto the pivot bolt (which will already be installed loosely in the WALL BRACKET). 5) SET THE TILT ANGLE – Once the speaker has nested securely on the pivot bolt, slide the second M6 34mm bolt into one of the holes in top of the wall bracket to set the angle. 5a) TILT ANGLES -- The bracket allows for +/-15 degrees of tilt. Some of the extreme tilt angles are not recommended because the speaker will run into the wall first. 5b) PRE- SET ANGLES and CONTINUOUSLY VARIABLE ANGLE -- The bracket has through holes for mounting angles of +/- 15 degrees in 5 degree increments. There is also a slot above the set of holes for continuously variable adjustment. The pre-set angles are recommended for accurate aiming. Either can be utilized for setting the speaker’s tilt angle. 5c) SECURE THE ANGLE SETTING -- Once the angle has been chosen, tighten both bolts with hardware provided. CBT 50LA-1 & CBT 100LA-1 Bracket Installation Guide – Page 6 6) 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 corner, 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.
